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
Use crankshaft pulley bolt to rotate engine in direction of ro-
tation until a full pulse tooth
(arrow) is centered in pulse sen-
sor opening.
Measure depth from pulse sensor mounting surface on trans-
mission to top of tooth.
Q Measure length (A) of pulse sensor from mounting surface to
end.
- Subtract length of pulse sensor (A) from distance to pulse
tooth from mounting area on transmission. This resulting
measurement is the pulse sensor air gap. Use shims avail-
able from
BMW to adjust air gap to specification.
Pulse air sensor gap
