| Removal | ||
1 | Remove the engine flywheel (1) | Truck | |
Bus | |||
| Check: | ||
2 | Clean the flywheel (1) and check it for cracks or stains with signs of overheating. | ||
3 | Check the flatness of the clutch contact surface on flywheel (1) with a precision straightedge (3). | Precision straightedge | |
4 | Check the mating surface and the tapped holes for the fastening of the clutch pressure plate | ||
Rectify | |||
5 | Machine the clutch friction surface of flywheel (1), observing coarseness of the finish. | Before machining the flywheel, check if it will be possible to remove the material. Before machining the flywheel, observe the maximum permissible measurement for stock removal. If the grooves are deeper than the authorized material elimination, replace flywheel (1). | |
Flywheel outside diameter (A) | |||
Ring gear seat diameter (B) | |||
Flywheel diameter on crankshaft flange (C) | |||
Diameter of the clutch housing (D) | |||
Maximum permissible steering wheel eccentricity (measured on ring gear seat surface) | |||
A higher coarseness will cause higher wear of the clutch disk lining, where as on a much more smoother finish, clutch disengaging presents difficulties for clutch uncoupling. | |||
Total flywheel thickness (F). | |||
When rectifying attrition surface, observe the minimum allowed distance (F) | |||
Permissible max. lateral deviation of steering wheel attrition face. | |||
Dynamic maximum imbalance of steering wheel with ring gear. | |||
| Installing | ||
6 | Install the engine flywheel (1) | Truck | |
