Rear BMW 3 SERIES 1989 E30 Workshop Manual

0•4Introduction
The E30 3-Series range first became
available in the UK in March 1983, and
continued in production until April 1991, when
the revised E36 3-Series range (not covered
by this manual) was introduced. Convertible
and Touring (Estate) models were introduced
for 1988, and these models have continued in
E30 form to date.
The E28 5-Series models were introduced
in October 1981, and were superseded in
June 1988 by the revised E34 5-Series range,
Touring versions of which became available
from March 1992. Throughout this manual,
E28 models are also referred to as “old-
shape”, while E34 models are designated
“new-shape”.
The models covered by this manual are
equipped with single overhead cam in-line
four- and six-cylinder engines. Early 316 and
518 models are fitted with carburettors, but all
other models are fitted with fuel injection
systems. Transmissions are a five-speed
manual, or three- or four-speed automatic.
The transmission is mounted to the back of
the engine, and power is transmitted to the
fully-independent rear axle through a two-
piece propeller shaft. The final drive unit is
bolted solidly to a frame crossmember, and
drives the rear wheels through driveshaftsequipped with inner and outer constant
velocity joints.
The front suspension is of MacPherson
strut type, with the coil spring/shock absorber
unit making up the upper suspension link. The
rear suspension is made up of coil spring-
over-shock absorber struts, or coil springs
and conventional shock absorbers,
depending on model.
The brakes are disc type at the front, with
either drums or discs at the rear, depending
on model. Servo assistance is standard on all
models. Some later models are equipped with
an Anti-lock Braking System (ABS).
All models are manufactured to fine limits,
and live up to the BMW reputation of quality
workmanship. Although many of the models
covered by this manual appear complex at
first sight, they should present no problems to
the home mechanic.

0•8Roadside Repairs
Jacking and wheel
changing
The jack supplied with the vehicle should
be used only for raising the vehicle when
changing a tyre or placing axle stands under
the frame.
Warning:Never crawl under the
vehicle or start the engine when
this jack is being used as the
only means of support.
When changing a wheel, the vehicle should
be on level ground, with the handbrake firmly
applied, and the wheels chocked. Select
reverse gear (manual transmission) or Park
(automatic transmission). Prise off the hub
cap (if equipped) using the tapered end of the
wheel brace. Loosen the wheel bolts half a
turn, leaving them in place until the wheel is
raised off the ground.
Position the head of the jack under the side
of the vehicle, making sure it engages with thepocket made for this purpose (just behind the
front wheel, or forward of the rear wheel).
Engage the wheel brace handle and turn it
clockwise until the wheel is raised off the
ground. Unscrew the bolts, remove the wheel
and fit the spare.
Refit the wheel bolts and tighten them
finger-tight. Lower the vehicle by turning the
wheel brace anti-clockwise. Remove the jack
and tighten the bolts in a diagonal pattern to
the torque listed in the Chapter 1
Specifications. If a torque wrench is not
available, have the torque checked by a BMW
dealer or tyre fitting specialist as soon as
possible. Refit the hubcap.
Towing
Vehicles with manual transmission can be
towed with all four wheels on the ground, if
necessary. Automatic transmission-equipped
vehicles can only be towed with all fourwheels on the ground providing that the
speed does not exceed 35 mph and the
distance is not over 50 miles, otherwise
transmission damage can result. For
preference, regardless of transmission type,
the vehicle should be towed with the driven
(rear) wheels off the ground.
Proper towing equipment, specifically
designed for the purpose, should be used,
and should be attached to the main structural
members of the vehicle, not to the bumpers or
bumper brackets. Sling-type towing
equipment must notbe used on these
vehicles.
Safety is a major consideration while
towing. The handbrake should be released,
and the transmission should be in neutral. The
steering must be unlocked (ignition switch
turned to position “1”). Remember that
power-assisted steering (where fitted) and the
brake servo will not work with the engine
switched off.
Jacking, towing and wheel changing

0•10Roadside Repairs
Puddles on the garage floor or drive, or
obvious wetness under the bonnet or
underneath the car, suggest a leak that needs
investigating. It can sometimes be difficult to
decide where the leak is coming from,
especially if the engine bay is very dirty
already. Leaking oil or fluid can also be blown
rearwards by the passage of air under the car,
giving a false impression of where the
problem lies.Warning: Most automotive oils
and fluids are poisonous. Wash
them off skin, and change out of
contaminated clothing, without
delay.
Identifying leaks
The smell of a fluid leaking
from the car may provide a
clue to what’s leaking. Some
fluids are distinctively
coloured. It may help to clean the car
carefully and to park it over some clean
paper overnight as an aid to locating the
source of the leak.
Remember that some leaks may only
occur while the engine is running.
Sump oil Gearbox oil
Brake fluid Power steering fluidOil from filter
Antifreeze
Engine oil may leak from the drain plug......or from the base of the oil filter.
Leaking antifreeze often leaves a crystalline
deposit like this.Gearbox oil can leak from the seals at the
inboard ends of the driveshafts.
A leak occurring at a wheel is almost
certainly brake fluid.Power steering fluid may leak from the pipe
connectors on the steering rack.

Brake and clutch fluid
Warning: Brake fluid can harm
your eyes and damage painted
surfaces, so use extreme caution
when handling or pouring it. Do
not use brake fluid that has been standing
open or is more than one year old. Brake
fluid absorbs moisture from the air, which
can cause a dangerous loss of brake
effectiveness. Use only the specified type
of brake fluid. Mixing different types (such
as DOT 3 or 4 and DOT 5) can cause brake
failure.
14The brake master cylinder is mounted at
the left rear corner of the engine
compartment. The clutch fluid reservoir
(manual transmission models) is mounted on
the right-hand side.
15To check the clutch fluid level, observe
the level through the translucent reservoir.
The level should be at or near the step
moulded into the reservoir. If the level is low,
remove the reservoir cap to add the specified
fluid (see illustration).
16The brake fluid level is checked by looking
through the plastic reservoir mounted on the
master cylinder (see illustration). The fluid
level should be between the MAX and MIN
lines on the reservoir. If the fluid level is low,
first wipe the top of the reservoir and the cap
with a clean rag, to prevent contamination of
the system as the cap is unscrewed. Top-up
with the recommended brake fluid, but do not
overfill.
17While the reservoir cap is off, check the
master cylinder reservoir for contamination. If
rust deposits, dirt particles or water droplets
are present, the system should be drained
and refilled.
18After filling the reservoir to the proper
level, make sure the cap is seated correctly, to
prevent fluid leakage and/or contamination.
19The fluid level in the master cylinder will
drop slightly as the disc brake pads wear.
There is no need to top up to compensate for
this fall provided that the level stays above the
MIN line; the level will rise again when new
pads are fitted. A very low level may indicateworn brake pads. Check for wear (see Sec-
tion 26).
20If the brake fluid level drops consistently,
check the entire system for leaks immediately.
Examine all brake lines, hoses and
connections, along with the calipers, wheel
cylinders and master cylinder (see Sec-
tion 26).
21When checking the fluid level, if you
discover one or both reservoirs empty or
nearly empty, the brake or clutch hydraulic
system should be checked for leaks and bled
(see Chapters 8 and 9).
Windscreen washer fluid
22Fluid for the windscreen washer system is
stored in a plastic reservoir in the engine
compartment (see illustration).
23In milder climates, plain water can be
used in the reservoir, but it should be kept no
more than two-thirds full, to allow for
expansion if the water freezes. In colder
climates, use windscreen washer system
antifreeze, available at any car accessory
shop, to lower the freezing point of the fluid.
This comes in concentrated or pre-mixed
form. If you purchase concentrated antifreeze,
mix the antifreeze with water in accordance
with the manufacturer’s directions on the
container.
Caution: Do not use cooling
system antifreeze - it will damage
the vehicle’s paint.
5 Tyre and tyre pressure
checks
1
1Periodic inspection of the tyres may save
you the inconvenience of being stranded with
a flat tyre. It can also provide you with vital
information regarding possible problems in
the steering and suspension systems before
major damage occurs.
2Tyres are equipped with bands that will
appear when tread depth reaches 1.6 mm, at
which time the tyres can be considered worn
out. This represents the legal minimum tread
depth; most authorities recommend renewing
any tyre on which the tread depth is 2 mm or
less. Tread wear can be monitored with a
simple, inexpensive device known as a tread
depth indicator (see illustration).
3Note any abnormal tyre wear (see
illustration overleaf). Tread pattern irregular-
ities such as cupping, flat spots and more
wear on one side than the other are
indications of front end alignment and/or
wheel balance problems. If any of these
conditions are noted, take the vehicle to a tyre
specialist to correct the problem.
4Look closely for cuts, punctures and
embedded nails or tacks. Sometimes, after a
nail has embedded itself in the tread, a tyre
will hold air pressure for a short time, or may

Weekly Checks

Cartridge-type oil filter
17Some models are equipped with a
cartridge-type oil filter. Unscrew the bolt,
remove the cover, and lift the filter out (see
illustrations).
18Compare the new cartridge with the old
one, to make sure they are the same type,
then lower it into the housing.
19Using a clean rag, wipe off the mounting
surface of the housing and cover. If necessary,
renew the rubber O-ring (see illustration).
Smear some clean oil on the O-ring and refit
the cover and bolt. Tighten the bolt securely.
All models
20Remove all tools and materials from under
the vehicle, being careful not to spill the oil
from the drain pan, then lower the vehicle.
21Add new oil to the engine through the oil
filler cap in the valve cover. Use a funnel to
prevent oil from spilling onto the top of the
engine. Pour the specified quantity of fresh oil
into the engine. Wait a few minutes to allow the
oil to drain into the sump, then check the level
on the dipstick (see Section 4 if necessary). If
the oil level is correct, refit the filler cap.
22Start the engine and run it for about a
minute. The oil pressure warning light may
take a few seconds to go out while the new
filter fills with oil; don’t rev the engine while
the light is on. While the engine is running,
look under the vehicle, and check for leaks at
the sump drain plug and around the oil filter. Ifeither one is leaking, stop the engine and
tighten the plug or filter slightly.
23Wait a few minutes, then recheck the level
on the dipstick. Add oil as necessary.
24During the first few days after an oil
change, make it a point to check frequently
for leaks and proper oil level.
25The old oil drained from the engine cannot
be re-used in its present state, and should be
discarded. Oil reclamation centres and some
service stations will accept the oil, which can
be recycled. After the oil has cooled, it can be
transferred into a container for transport to a
disposal site.
7 Power steering fluid level
check
1
1Check the power steering fluid level
periodically to avoid steering system
problems, such as damage to the pump.
Proceed as follows.Caution: Do not hold the steering
wheel against either stop (full-left
or full-right lock) for more than
five seconds. If you do, the power
steering pump could be damaged.
2On some models, the power steering fluid
reservoir is located on the left side of the
engine compartment, and has a twist-off cap
with an integral fluid level dipstick (see
illustration). Other models use a hydraulic
power steering and brake servo system which
combines the fluid in one reservoir, located at
the right rear corner of the engine
compartment.
3Park the vehicle on level ground, and apply
the handbrake.
4On models with a fluid dipstick, run the
engine until it has reached normal operating
temperature. With the engine at idle, turn the
steering wheel back and forth several times to
get any air out of the steering system. Switch
off the engine, remove the cap by turning it
anti-clockwise, wipe the dipstick clean, and
refit the cap. Remove the cap again, and note
the fluid level. It must be between the two
lines (see illustration).
5On hydraulic servo models, pump the brake
pedal about ten times or until the pedal is firm.
Remove the nut, lift the cap off, and make
sure the fluid is within 6.0 mm of the top of the
reservoir.
6Add small amounts of fluid until the level is
correct (see illustration).

Caution: Do not overfill the
reservoir. If too much fluid is
added, remove the excess with a
clean syringe. Refit the cap.
7If frequent topping-up is needed, check the
power steering hoses and connections for
leaks and wear (see Section 10).
8Check the condition and tension of the
drivebelt (see Section 11).
8 Automatic transmission fluid
level check
1
Caution: The use of transmission
fluid other than the type listed in
this Chapter’s Specifications
could result in transmission
malfunctions or failure.
1The automatic transmission fluid should be
carefully maintained. Low fluid level can lead
to slipping or loss of drive, while overfilling
can cause foaming and loss of fluid. Either
condition can cause transmission damage.
2Since transmission fluid expands as it heats
up, the fluid level should only be checked
when the transmission is warm (at normal
operating temperature). If the vehicle has just
been driven over 20 miles (32 km), the
transmission can be considered warm. You
can also check the fluid level when the
transmission is cold. If the vehicle has not
been driven for over five hours and the fluid is
about room temperature (20°C), the
transmission is cold. However, the fluid level
is normally checked with the transmission
warm, to ensure accurate results.
Caution: If the vehicle has just
been driven for a long time at
high speed or in city traffic, in hot
weather, or if it has been pulling
a trailer, an accurate fluid level reading
cannot be obtained. Allow the trans-
mission to cool down for about 30 minutes.
3Immediately after driving the vehicle, park it
on a level surface, apply the handbrake and
start the engine. While the engine is idling,
depress the brake pedal and move theselector lever through all the gear ranges,
beginning and ending in Park.
4The automatic transmission dipstick tube is
located in the left rear corner of the engine
compartment.
5With the engine still idling, pull the dipstick
out of the tube (see illustration), wipe it off
with a clean rag, push it all the way back into
the tube and withdraw it again, then note the
fluid level.
6The level should be between the two marks
(see illustration). If the level is low, add the
specified automatic transmission fluid through
the dipstick tube - use a clean funnel,
preferably equipped with a fine mesh filter, to
prevent spills.
Caution: Be careful not to
introduce dirt into the
transmission when topping up.
7Add just enough of the recommended fluid
to fill the transmission to the proper level. It
takes about half a litre to raise the level from
the low mark to the high mark when the fluid
is hot, so add the fluid a little at a time, and
keep checking the level until it’s correct.
8The condition of the fluid should also be
checked along with the level. If the fluid is
black or a dark reddish-brown colour, or if it
smells burned, it should be changed (see
Section 28). If you are in doubt about its
condition, purchase some new fluid, and
compare the two for colour and smell.
9 Tyre rotation
1
1The tyres can be rotated at the specified
intervals, or whenever uneven wear is noticed.
However, bear in mind that if rotation
succeeds in making all the tyres wear evenly,
you will eventually have to renew all four at
once. Since the vehicle will be raised and the
wheels removed anyway, check the brakes
also (see Section 26). Note: Even if you don’t
rotate the tyres, at least check the wheel bolt
tightness.
2It is recommended that the tyres be rotatedin a specific pattern (see illustration)so that
their direction of rotation remains the same.
3Refer to the information in “Jacking and
towing”at the front of this manual for the
proper procedure to follow when raising the
vehicle and changing a tyre.
4The vehicle must be raised on a hoist or
supported on axle stands to get all four tyres
off the ground. Make sure the vehicle is safely
supported!
5After the rotation procedure is finished,
check and adjust the tyre pressures as
necessary, and be sure to check the wheel
bolt tightness.
10 Underbonnet hose check
and renewal
3
Warning: Renewal of air
conditioning hoses must be left
to a dealer service department or
air conditioning specialist having
the equipment to depressurise the system
safely. Never disconnect air conditioning
hoses or components until the system has
been depressurised.
General
1High temperatures under the bonnet can
cause deterioration of the rubber and plastic
hoses used for various systems. Periodic
inspection should be made for cracks, loose
clamps, material hardening, and leaks.
2Information specific to the cooling system
can be found in Section 22, while the braking
system is covered in Section 26.
3Most (but not all) hoses are secured with
clamps. Where clamps are used, check to be
sure they haven’t lost their tension, allowing
the hose to leak. If clamps aren’t used, make
sure the hose has not expanded and/or
hardened where it slips over the fitting,
allowing it to leak.
Vacuum hoses
4It’s quite common for vacuum hoses,
especially those in the emissions system, to
be colour-coded or identified by coloured

no cause for concern. Make sure that any fluid
noted is from the struts/shocks, and not from
any other source. If leakage is noted, renew
the struts or shock absorbers in axle pairs (or
as a full set).
7Check the struts/shock absorbers to be
sure that they are securely mounted and
undamaged. Check the upper mountings for
damage and wear. If damage or wear is
noted, renew the struts or shock absorbers.
8If the struts or shock absorbers must be
renewed, refer to Chapter 10 for the
procedure. Always renew both units on the
same axle, or the safety of the vehicle may be
compromised. If possible, renew all four as a
set.
Steering and suspension check
9Inspect the steering system components
for damage and distortion. Look for leaks and
damaged seals, boots and fittings.
10Clean the lower end of the steering
knuckle. Have an assistant grasp the lower
edge of the tyre and move the wheel in and
out, while you look for movement at the
steering knuckle-to-axle arm balljoints.
Inspect the balljoint boots for tears (see
illustration). If there is any movement, or the
boots are torn or leaking, the balljoint(s) must
be renewed.
11Grasp each front tyre at the front and rear
edges, push in at the front, pull out at the rear
and feel for play in the steering linkage. If any
free play is noted, check the steering gear
mountings and the track rod balljoints for
looseness. If the steering gear mountings are
loose, tighten them. If the track rods are
loose, the balljoints may be worn (check to
make sure the nuts are tight). Additional
steering and suspension system information
can be found in Chapter 10.
25 Driveshaft gaiter check
1
1The driveshaft gaiters are very important
because they prevent dirt, water and foreign
material from entering and damaging the
constant velocity (CV) joints. External oil and
grease contamination can cause the gaitermaterial to deteriorate prematurely, so it’s a
good idea to wash the gaiters with soap and
water.
2Inspect the gaiters for tears and cracks, as
well as for loose clamps (see illustration). If
there is any evidence of cracks or leaking
lubricant, the gaiter must be renewed (see
Chapter 8).
26 Brake system check
2
Warning: Dust produced by lining
wear and deposited on brake
components may contain
asbestos, which is hazardous to
your health. Do not blow it out with
compressed air, and don’t inhale it! Do not
use petroleum-based solvents to remove
the dust. Brake system cleaner or
methylated spirit should be used to flush
the dust into a drain pan. After the brake
components are wiped with a damp rag,
dispose of the contaminated rag(s) and the
drain pan contents into a covered and
labelled container. Try to use asbestos-
free new parts whenever possible.
Note:In addition to the specified intervals, the
brake system should be inspected each time
the wheels are removed or a malfunction is
indicated. Because of the obvious safety con-
siderations, the following brake system checks
are some of the most important maintenance
procedures you can perform on your vehicle.
Symptoms of brake system
problems
1The disc brakes have built-in electrical wear
indicators which cause a warning light on the
dash to come on when they’re worn to the
renewal point. When the light comes on,
renew the pads immediately, or expensive
damage to the brake discs could result.
2Any of the following symptoms could
indicate a potential brake system defect:
a) Vehicle pulls to one side when the brake
pedal is depressed
b) Brakes make squealing or dragging noises
when applied
c) Brake pedal travel excessived) Brake pedal pulsates (normal if ABS is
working)
e) Brake fluid leaks (usually on the inner side
of the tyre or wheel)
3If any of these conditions are noted, inspect
the brake system immediately.
Brake lines and hoses
Note: Steel brake pipes are used throughout
the brake system, with the exception of
flexible, reinforced hoses at the front wheels
and as connectors at the rear axle. Periodic
inspection of all these lines is very important.
4Park the vehicle on level ground, and
switch off the engine. Remove the wheel
covers. Loosen, but do not remove, the bolts
on all four wheels.
5Raise the vehicle and support it securely on
axle stands.
6Remove the wheels (see “Jacking and
towing” at the front of this book, or refer to
your owner’s handbook, if necessary).
7Check all brake lines and hoses for cracks,
chafing of the outer cover, leaks, blisters, and
distortion. Check the brake hoses at front and
rear of the vehicle for softening, cracks,
bulging, or wear from rubbing on other
components. Check all threaded fittings for
leaks, and make sure the brake hose
mounting bolts and clips are secure.
8If leaks or damage are discovered, they
must be repaired immediately. Refer to
Chapter 9 for detailed brake system repair
procedures.
Disc brakes
9If it hasn’t already been done, raise the
vehicle and support it securely on axle stands.
Remove the front wheels.
10The disc brake calipers, containing the
pads, are now visible. Each caliper has an
outer and an inner pad - all pads should be
checked.
11Note the pad thickness by looking
through the inspection hole in the caliper (see
illustration). If the lining material is 2.0 mm
thick or less, or if it is tapered from end to
end, the pads should be renewed (see
Chapter 9). Keep in mind that the lining
1•22
26.11 Look through the caliper inspection
window to inspect the brake pads - the
pad lining which rubs against the disc can
also be inspected by looking through each
end of the caliper25.2 Gently probe the driveshaft boots to
check for cracks24.10 Inspect the balljoint boots for tears

Every 12 000 miles

material is bonded to a metal plate or shoe -
the metal portion is not included in this
measurement. Always renew the pads on
both sides of the vehicle (in axle sets), even if
only one pad of the four is worn, or uneven
braking may result.
12Remove the calipers without
disconnecting the brake hoses (see Chap-
ter 9).
13Check the condition of the brake disc.
Look for score marks, deep scratches and
overheated areas (they will appear blue or
discoloured). If damage or wear is noted, the
disc can be removed and resurfaced by an
engineering workshop; otherwise, it will have
to be renewed. In either case, both discs
should be involved, even if only one is worn.
Refer to Chapter 9 for more detailed
inspection and repair procedures.
Drum brakes
14Refer to Chapter 9 and remove the rear
brake drums.
15Note the thickness of the lining material
on the rear brake shoes, and look for signs of
contamination by brake fluid or grease (see
illustration). If the material is within 2.0 mm of
the recessed rivets or metal shoes, renew the
brake shoes. The shoes should also be
renewed if they are cracked, glazed (shiny
lining surfaces), or contaminated with brake
fluid or grease. See Chapter 9 for the renewal
procedure.
16Check the shoe return and hold-down
springs and the adjusting mechanism. Make
sure all these components are fitted correctly,and are in good condition. Deteriorated or
distorted springs, if not renewed, could allow
the linings to drag and wear prematurely.
17Check the wheel cylinders for leakage by
carefully peeling back the rubber boots. Slight
moisture behind the boots is acceptable. If
brake fluid is noted behind the boots or if it
runs out of the wheel cylinder, the wheel
cylinders must be overhauled or renewed (see
Chapter 9).
18Check the drums for cracks, score marks,
deep scratches and high spots, which will
appear as small discoloured areas. If
imperfections cannot be removed with emery
cloth, both drums must be resurfaced by a
specialist (see Chapter 9 for more detailed
information).
19Refer to Chapter 9 and fit the brake
drums.
20Refit the wheels, but don’t lower the
vehicle yet.
Handbrake
21The easiest, and perhaps most obvious,
method of checking the handbrake is to park
the vehicle on a steep hill with the handbrake
applied and the transmission in Neutral (stay
in the vehicle while performing this check). If
the handbrake doesn’t prevent the vehicle
from rolling, refer to Chapter 9 and adjust it.
27 Wiper blades -
check and renewal
1
1Road film can build up on the wiper blades
and affect their efficiency, so they should bewashed regularly with a mild detergent
solution.
Check
2The wiper and blade assembly should be
inspected periodically. If inspection reveals
hardened or cracked rubber, renew the wiper
blades. If inspection reveals nothing unusual,
wet the windscreen, turn the wipers on, allow
them to cycle several times, then switch them
off. An uneven wiper pattern across the glass,
or streaks over clean glass, indicate that the
blades should be renewed.
3The operation of the wiper mechanism can
loosen the retaining nuts, so they should be
checked and tightened, as necessary, at the
same time the wiper blades are checked (see
Chapter 12 for further information regarding
the wiper mechanism).
Wiper blade renewal
4Pull the wiper/blade assembly away from
the glass.
5Press the retaining tab in, and slide the
blade assembly down the wiper arm (see
illustration).
6If you wish to renew the blade rubbers
separately, detach the end of the rubber from
the wiper blade frame, then slide the rubber
out of the frame (see illustration).
7Compare the new rubber with the old for
length, design, etc.
8Slide the new rubber into place, and insert
the end in the wiper blade frame to lock it in
place.
9Refit the blade assembly on the arm, then
wet the glass and check for proper operation.

28 Automatic transmission fluid
and filter change
1
1At the specified intervals, the transmission
fluid should be drained and renewed. Since
the fluid will remain hot long after driving,perform this procedure only after the engine
has cooled down completely.
2Before beginning work, purchase the
specified transmission fluid (see “Lubricants
and fluids”at the beginning of this Chapter)
and a new filter.
3Other tools necessary for this job include axle
stands or ramps to support the vehicle in araised position, a drain pan capable of holding at
least 4.5 litres, and newspapers and clean rags.
4Raise the vehicle and support it securely.
5Loosen the dipstick tube collar, then detach
the dipstick tube and let the fluid drain (see
illustrations).
6Remove the transmission sump mounting
bolts and brackets (see illustration).
