Severe Misalignment Between Mating Surfaces
Indicator:
Loss of dive/Poor clutch performance
Cause:
1. Engine to gearbox dowels missing or damaged
2. Gearbox and/or engine mounting face damaged or have high levels of contamination
3. Obstructions between engine and gearbox mounting face preventing the gearbox to be flush to the engine when mounted.
4. Missing/damaged or incorrectly torqued gearbox mounting bolts
Effect:
Clutch disc failure due to mis-alignment (gearbox centre off-axis to crankshaft)
Action:
1. Replace clutch kit
2. Replace gearbox dowels
3. Ensure the gearbox and engine mating surfaces are free from contamination.
4. Ensure there are no obstructions between engine and gearbox when final torqueing of the gearbox mounting bolts
5. Replace worn or damaged gearbox mounting bolts if necessary
