PROBLEM:
WORN RELEASE BEARING THRUST FACE
If the release bearing is misaligned excessively, the vehicle will suffer from a noisy and jerky clutch pedal action.
REMEDY:
Correct the cause of the misalignment and, naturally, renew the bearing.
PROBLEM:
BROKEN SEGMENT NECKS
The angular misalignment of engine and gearbox will cause the loss of drive.
REMEDY:
Correct the misalignment, which might be due to a number of problems, including a bent engine back plate, burrs or debris trapped between the mating surfaces, a cracked bell housing, worn pilot or gearbox bearings or the incorrect/missing dowels.
PROBLEM:
BROKEN DAMPER SPRINGS AND WORN CENTRE
If the engine and gearbox interface is not aligned correctly, the result will be high levels of noise and vibration and, ultimately, total failure.
REMEDY:
As above, but specifically check for the correct position and condition of the gearbox dowels and dowel holes.
PROBLEM:
DAMAGED SPLINE
Failure to correctly align the spline with the driven plate during gearbox installation will cause clutch drag.
REMEDY:
Replace the driven plate and take care to line up the components during gearbox installation.
PROBLEM:
WORN AWAY HUB SPLINES
Caused by a bent motion shaft or worn gearbox bearings, the end result can be a loss of drive.
REMEDY:
Rectify the relevant gearbox fault and then replace the driven plate.
PROBLEM:
WORN DIAPHRAGM SPRING FINGERS
Failure to maintain contact between the bearing and clutch assembly can result in jerky clutch engagement.
REMEDY:
Renew the clutch assembly and check the release mechanism (including its self-adjustment) for its correct operation. Observe the correct adjustment frequency and procedure.
