| Remove | ||
1 | Remove the flywheel (1). | ||
| Check | ||
2 | Clean the flywheel (1) and review it for cracks, burn spots or streaks and check the flatness of the flywheel friction surface with a wire ruler (2). | If a discrepancy is found, it must be ground. Before grinding the flywheel, check the possibility of removing material. If the cracks or streaks are deeper than the material approved for removal, replace the flywheel (1). | |
Grind | |||
3 | Grind the flywheel. | Overall diameter of the flywheel (F). | |
Rack housing diameter (A). | |||
Clutch housing diameter (E). | |||
Flywheel thickness (D). | |||
If the surface of contact with the clutch must be ground, make sure that the measure (C) remains within the specified values. | |||
Contact surface roughness. | |||
Greater roughness leads to early wear of the clutch plate lining, while a very smooth finish poses challenges when decoupling the clutch. | |||
| Check | ||
4 | Diameter (G) | ||
5 | Coupling diameter (B). | ||
6 | Diameter for the false track of the rear seal (H). | ||
7 | Maximum eccentricity in the rack housing. | ||
8 | Maximum dynamic imbalance of the flywheel with the rack. | ||
9 | Maximum lateral deviation on the friction face. | ||
Outside diameter of the false track of the rear retainer | |||
Maximum length for reuse of flywheel bolts | |||
