The fuelpump will be damaged if run without fuel.
* If the filler neck has been removed from the body, be
sure to reattach the
neck grounding screw (where ap-
plicable). Check electrical resistance between the
ground tab and wheel

Running losses (312-way) valve,
removing and installing
The running losses (312-way) valve is located under the car
beneath the driver's seat, just ahead of the fuel filter. A protec-
tive covershieldsfuel system components from road hazards
and dirt.
The engine control module
(ECM) controls the operation of
the 312-way valve (pulse-width modulated). On engine start
up, the valve solenoid is energized for 20 seconds in order to
supply full fuel volume to the fuel rail.
After20 seconds, the
solenoid is deactivated and sprung closed (the bypass is
opened). This reduces the amount of fuel circulating through
the fuel rail and diverts the excess to return to the fuel tank
through the fuel pressure regulator.
The fuel injectors are supplied with pressurized fuel, but ex-
cess fuel is diverted to the fuel tank without first passing
through the fuel rail. This prevents the excess fuel from ab-
sorbing heat in the engine compartment, thus lowering the
temperature and amount of vaporization in the fuel tank.

This repair group covers general application information for
the clutch, manual and automatic transmissions, shift linkag-
es and driveshaft.
Drivetrain
I ZF manual transmission I
BMW E39 models are equipped with a longitudinal drivetrain.
The transmission is bolted directly to the rear of the engine.
A
driveshaft connects the output shaft of the transmission to the
rear final drive. Individual drive axles with integrated constant
velocity joints transfer rotational power from the final drive
unit to the rear wheels.
4 Due to different power characteristics and performance re-
quirements, various manual transmissions are used in mod-
els covered by this manual. Manual transmission
applications are given in the table below.
For manual transmission specifications or repair procedures,
refer to
230 Manual Transmission.
Manual transmission models use a single disc clutch with
dual-mass flywheel. For further information, see
210 Clutch.
The manual transmission metal ID plate is mounted on side of
transmission. Do not rely on numbers cast on transmission
case for identification.

1 Clutch
This repair group covers replacement of clutch mechanical
and hydraulic components.
BMW 5 Series models with manual transmission use a single
disc hydraulically actuated clutch.
Twoversions of the clutch
are used:
1997
5281 (6 cylinder) uses traditional clutch components.
All 540i (V-8) and 1998 and later
6 cylinder models use a
self-adjusting clutch (SAC).
NOTE-
See 200 Transmission-General for transmission applica-
tion information.
Special tools
Some special tools and techniques are required for clutch re-
pairs. Be sure to read a procedure through before beginning a
job.

Clutch
Installing the non-SAC clutch (1 997 5281 model) requires the
use of only a flywheel lock and traditional clutch disc align-
ment tool.
Installing the self-adjusting clutch (SAC) requires several
special tools for aligning and assembling the clutch, as well as
locking the flywheel in place. In addition, the procedure for re-
installing a previously used SAC differs from the procedure
for installing
a new SAC. Be sure to read the SAC installation
procedure through before starting the job.
The pressure plate of the SAC uses a spring-loaded wedge
rino to cornoensate for clutch disc wear. The wedge ring
ad-
;u$s by means of spr'ng tenson, so specal toolsh~st be
used to
appy and relieve spring tension as the c utch pres-
sure plate is installed.
