Determining Distance "X"
1. Crankshaft must contact thrust bearing
toward the rear. Use a lever to press
flywheel in direction of transmission, until
axial play of crankshaft is eliminated.
2. Determine distance "A", by using 9211
and measuring distance from engine
flange to flywheel mating surface.
Note:
Mark thickness of gauge when measuring.
Example:
Measured value 52.5 mm
Gauge thickness - 40.0 mm
Distance "A" 12.5 mm
3. Mount transmission on central tube to
specified torque. Screw in clamping
sleeve mounting bolt by hand (do not
tighten).
4. Push drive flange with bushing, but without
shims, on to central shaft and install
circlip.
5. Use a suitable lever and push central shaft
on drive flange far enough forward, that
central shaft rests on rear clamping screw
in shaft groove.
6. Tighten rear mounting bolt for clamping
sleeve to 75. 85 Nm/54. 61 ftlb.
7. Push drive flange forward against stop
on circlip and tighten bolt.
8. Determine distance "B". Use 9211 and
measure distance from clutch housing to
drive plate bearing surface (as far in as
possible).
