Lubrication System
This repair group covers lubrication system troubleshooting
as well as oil pan removal and oil pump replacement.
In 6-cylinder models, removal of the oil pan requires the re-
moval of the exhaust system and some front suspension
components. Those procedures are fully covered in:
180 Exhaust System
210 Clutch
230 Manual Transmission
0 240 Automatic Transmission
310 Front Suspension
320 Steering and Wheel Alignment
NOTE-
Oil change procedure and oil filter replacement are covered
in
020 Maintenance.
CAUTIOG
V8 engines: The oil pump fasteners (including the sprocket
retaining nut) are known to vibrate loose. This can result in oil
starvation and engine failure. Be sure to check oil bolts and
nut tightness whenever the
oilpump is accessible. If any fas-
teners are found to be loose, remove them and reinstall with
Loctite
Band torque to specifications.
Special tools
The engine needs to be properly supported while the front
suspension
subframe is lowered to access the oil pan.
A standard oil pressure gauge may be used for measuring oil
pressure.

4 Support subframe from below using BMW special tool 31 2
220 and appropriate shop lift. Remove
subframe mounting
bolts and lower
subframe as far as possible.
Remove oil pan screws (arrows) at cylinder block and trans-
mission bellhousing. Lower and remove oil pan.
NOTE-
If oil pan will not slide backwards, disconnect stabilizer bar
links and lower front axle support further.
If the oil pan does not separate easily from the engine cylin-
der
block, a few taps with a rubber malletshould breakit free.
Do not
pry the oil pan loose.
When installing oil pan: Thoroughly clean all old gasket material from mating sur-
faces and use a new gasket.
Apply a small amount of non-hardening sealer
(3 Bond
12098 or equivalent) to oil pan gasket directly below joints
(arrows) for end cover and front timing case cover. Apply
a bead
3 mm wide by 2 mm high.
Install all oil pan bolts finger tight. Tighten oil pan bolts to-
ward front of engine first, then pan bolts at transmission
end.

Automatic Transmission
4 Remove transmission cooler line clamp mounting nut (ar-
row) from transmission bell housing. Disconnect cooler lines
from transmission.
- Disconnect both transmission cooler fluid lines from trans-
mission.
CAUTION-
Place a pan under transmission fluid lines to catch dripping
fluid.

[~us~ension, Steering and Brakes - General
This section of the manual covers front and rear suspension,
braking and steering systems, and contains wheel, tire and
wheel alignment information and specifications. Also covered
here are the integrated braking and suspension systems in-
cluding
antilock braking (ABS), traction control (ASCIDSC),
and electronic height control (EHC).
Vehicle ride height information is at the end of this repair
group. Alignment information is in
320 Steering and Wheel
Alignment.
Aluminum suspension components
In order to reduce vehicle weight, aluminum suspension com-
ponents are used in some models. A test with a magnet will
easily reveal the metal used. If working with aluminum com-
ponents, be sure to read and follow the cautions below.
CAUTION-
* Due to the chemical and corrosion characteristics of alumi-
num, do not bring into contact with battery acid.
Do not use wire brushes with brass or iron bristles.
Only use brushes with stainless steel bristles.
Do not expose to flying sparks from
grinding/cutting op-
erations.
Do not subject to steel welding splashes.
Do not expose to temperatures over
80°C (176"F),
even for short periods. Temperatures in painting facili-
ties are not a problem.
The E39 front suspension subframe is used as a rigid mount-
ing platform for the front suspension arms, stabilizer bar and
steering gear.
The suspension arms, known as the lower control arms and
the tension struts (thrust arms), are connected to the
sub-
frame through rubber bushings. The arms are connected to
the steering
knucltles in a double pivot configuration.
Each front strut assembly includes a tubular strut and a coil
spring. The upper strut mount includes a bearing. The lower
end of each strut housing is fitted to the steering knuckle. The
integral wheel bearing and hub are bolted to the steering
Iknucltle.
6-cylinder and V-8 models use different steering systems and
other front suspension components.
