Removal and installation oil pump drive shaft bushings
1 – mandrel A.60333/1/2
Check the inner diameter of the bushings, their press fit in the sockets, and the alignment 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 if the surfaces of the bushings are damaged or their pressing is weakened, replace the bushings.
When replacing, use the A.60333/1/2 mandrel for both removal and installation, observing the following:
(The original is on the portal www.vazbook.ru)
- the bushings must be pressed into the sockets, while the oil hole in the front bushing must be opposite the channel in the cylinder block;
- after pressing, the bushings must be finally processed and finished according to the internal diameter. In order to ensure complete alignment of the shaft bushings, the A.90353 reamer is used for their finishing, with which both bushings are processed simultaneously.
