Preventative maintenance Examination and refit of clutch environment

4.1.2 Gearbox ●● Remove all the dust and the grease from the clutch housing and from the clutch linkage. ●● Check the input shaft seal and tube guide. ●● Check the state of tube-guide (wear, jamming) and replace it if necessary.

Advice   Replace all the damaged parts (worn, jammed…)

Friction surface

Check the surface The thickness of machining the friction surface is maximum 0.7 mm. The roughness is Ra 2.5 to 6.3. Attention Ɂ Ɂ In the event that the cover assembly bolting surface is different from the friction surface (hollow flywheel or flat flywheel with redan), machine the same thickness of material on the 2 surfaces. Advice   When re-machining the flywheel, it is compul- sory to respect the maximum authorized machining amount so as to ensure its strength (risk of breakage) and it's minimum mass (thermal capacity).

●● Check the state of the flywheel; re-machine the friction surface (cracks on surface, worn areas…) if necessary or replace the flywheel. In any case follow strictly manufacturer’s instructions. ●● Follow the instructions (bolting method and bolting torque), and the assembly's specifications (systematic replacement of the bolts, use of lock thread).
