tive Equipment (PPE) as indicated in this manual, including protective goggles, gloves, and safety
footwear.
Failure to comply could result in death or serious injury.
Important points to be taken into account while replac-
ing clutch:
1. Check the condition of spigot bearing replace if neces-
sary.
2. Check the condition of the oil seals on the engine and
transmission sides for leaks and replace if necessary.
3. Check the flywheel face is free from scores and cracks.
When machining the surface, follow specified toler-
ances.
NOTE: Machine the bolting surface to the same amount of
the running surface, to maintain original clamp loads.
Always use suitable tools to align holes. Do not use hands
or fingers.
4. Make sure that the alignment of the clutch cover
to the flywheel is correct. Use special tool number
380000612 for alignment.
5. Make sure that the clutch cover is secured to the fly-
wheel evenly and sequentially. Use new spring wash-
ers.
6. After an initial running-in period, any variation lever
height will correct itself.
7. Before fitting check the clutch plate for lateral runout.
8. Make sure that the clutch plate is fitted the correct way.
Observe the direction as indicated on the driven plate.
9. Check the gearbox input shaft for damage. Only non-
metallic based high melting point grease should be
used to lubricate the splines and release bearing guide
sleeve.
10. Check the release bearing guide sleeve for wear and
replace if necessary.
11. After applying the grease to the gearbox input shaft,
guide the clutch driven plate on to the shaft and re-
move the surplus grease.
12. Make sure that the alignment between the engine and
transmission/clutch housing is correct. Make sure that
the locating dowels are fit and secure.
13. Carefully guide the input shaft into the clutch hub
splines. Do not allow the weight of the transmission to
hang on the hub of the driven plate. This will prevent
irreparable damage to the segments and associated
cushion springs.
14. Make sure that the adjustment of clutch pedal free play
is correct.
