Removal and installation of plugs of the roller of a drive of the oil pump
1 - mandrel А.60333/1/2
Check the inner diameter of the bushings, their pressing into the sockets, as well as the coincidence of the lubrication hole in the front bushing with the channel in the cylinder block (turning the sleeve). The inner surface must be smooth and free of burrs.
If the gap between the bushings and the bearing surfaces of the roller exceeds 0.15 mm (wear limit), and also in case of damage to the surfaces of the bushings or weakening of their pressing, replace the bushings.
When replacing, use tool A.60333/1/2 both for removal and installation, observing the following:
- the bushings must be pressed into the sockets, while the oil hole in the front bushing must be against the channel in the cylinder block;
- after pressing in, the bushings must be finished and finished to the inside diameter. To ensure complete alignment of the shaft bushings, a reamer A.90353 is used to finish them, which simultaneously processes both bushings.
