| REMOVAL | ||
1 | Remove the flywheel | ||
| Check | ||
2 | Clean the flywheel (1) and check it for cracks or stains with signs of overheating. | ||
3 | Check the friction surface of flywheel (1) for evenness | Utilize a precision straight edge (2). | |
4 | Control the thrust surface and the tapped holes (3) for the fastening of the clutch pressure plate | ||
Machine | |||
5 | Machine the clutch friction surface of flywheel (1), observing coarseness of the finish. | A rougher surface finish will cause rapid clutch lining wear, while a too smooth finish could cause difficulties in clutch disengagement. | |
Before machining the flywheel, check if it will be possible to remove the material. When machining the flywheel, observe the maximum permissible measure for material removal. If the fissures are deeper than the authorized material removal, replace the flywheel. | |||
