NOTE: Since each tire/wheel assembly weighs approximately 14 kg (30 lbs), placing the front wheels in trunk can assist
with the weight distribution.
1. Place the lift blocks as shown
2. Raise the hoist a lew inches (centimeters) and rock the car to be sure it is firmly supported.
3. Raise the hoist to full height and inspect lift points for solid support.

Towing
rl
It the car needs to be towed, call a professional towingservice. Never tow the car behind another car with just
a rope or chain. lt is very dange.ous.
Emergency Towing
There are three popular methods of towing a car:
Flat-bed Equipmont-The operator loads the car on theback of a truck. This is the best way of transporting thecar.
Whsol Lift Equipment-The tow truck uses two oivot-ing arms that go under the tires (front or rear) and liftsthem otf the ground. The other two wheels remain onthe ground.
Sling-type Equipmont-The tow truck uses metal cableswith hooks on the ends. These hooks go around partsof the frame or suspension and the cables lift that endof the car off the ground. The car's suspension and bodvcan be seriously damaged if this method of towing is at-tempted.
It the car cannot be transponed by flat-bed, it should betowed with the tfont wheels oft the ground. lf due todamage. the car must be towed with the front wheelson the ground, do the tollowing:
Manual Transmission
a Release the parking brake,a Shift the transmission to Neutral.
Automatic Transmission
a Release the parking brake.a Start the engine.
a Shift to @ oosition, then to S position.
a Turn off the engine.
NOTICE: lmproper towing preparation will damage thetransmission. Follow the above procedure exactly. lf you
cannot shift the transmission or stan the engine (auto-
matic transmission), your car must be transDorted on aflat-bed.
a lt is best to tow the car no tarther than SO miles lgokm). and keep the speed below 3b mph (bE km/h).
NOTICE: Trying to litt or tow your car by the bumperswill cause serious damage. The bumpers are not designedto support the car's weight.

Main Bearings
Clearance
To check main bearing-to-journal oil clearance,
remove the main caps and bearing halves.
Clean each main journal and bearing half with a
clean shop towel.
Place one strip of plastigage across each main iour-
nal.
NOTE: lf the engine is still in the car when you bolt
the main caD down to check clearance, the weight
of the crankshaft and flywheel will flatten the plasti-
gage further than just the torque on the cap bolt,
and give you an incorrect reading. Fot an accurate
reading, support the crank with a iack under the
counterweights and check only one bearing at a
trme.
Reinstall the bearing caps and cap bridge (818C1
engine only) then torque the bolts.

NOTE: Do not rotate the crankshaft during inspec-
tron,
Remove the cap bridge (818C1 engine only), caps
and bearings again, and measure the widest part oJ
the plastigage.

PLASTIGAGE STNIP
lf the plastigage measures too wide or too narrow,
(remove the engine if it's still in the car), remove the
crankshaft. and remove the upper half of the bear-
ing. Install a new. complete bearing with the same
color code (select the color as shown in the right
column), and recheck the clearance.
CAUTION: Do not file, shim, or scrapo ihe bo.rings
or the caps to adiust clearance.
lf the plastigage shows the clearance is still incor-
rect, try the next larger or smaller bearing (the color
listed above or below that one), and check again.
NOTE: lf the Droper clearance cannot be obtained
by using the appropriate larger or smaller bearings,
reolace the crankshaft and start over.

CAUTION: lf ths codes are indeciphorable becau3o ot

Valve Body
Repair
NOTE: This repair is only necessary il one or more of
the valves in a valve body do not slide smoothly in their
bores. You may use this procedure to lree the valves in
the valve bodies.
1. Soak a sheet of #600 abrasive paper in ATF for
about 30 minutes.
2. Carefully tap the valve body so the sticking valve
drops out of its bore.
CAUTION: lt may be necessary to use a small
screwdiiver to pry the the valve lree. Be carelul not
to sclatch the bore with ihe sc.ewdliver.
3. Inspect the valve tor any scuff marks. Use the ATF-
soaked # 600 pagper to polish off any burrs that are
on the valve, than wash the valve in solvent and dry
it with compressed air.
4. Roll up halt a sheet oI ATF-soaked paper and insert
it in the valve bore of the sticking valve.
Twist the paper slightly, so that it unrolls and fits
the bore tightly, then polish the bore by twisting the
paper as you push it in and out.
CAUTION: The valve body is aluminum and doesn't
require much polishing to remove any burs.

Remove the #600 paper and thoroughly wash the
entire valve body in solvent, then dry with com-
perssed air.
Coat the valve with ATF then drop it into its bore.
It should drop to the bottom o{ the bore under its
own weight. lf not. repeat step 4 then retest.
VALVE BODY
Remove the valve and thoroughly clean it and the
valve body with solvent. Dry all parts with com
pressed air, then reassemble using ATF as a
lubricant.
