The way of fastening of the oil pump is shown in fig. 452. When removing, proceed as follows:
- remove the oil pan (subsection 18.1);
- unscrew the bolts of the oil pump housing;
- pull the pump down so that the shaft disengages, and then pull it out completely;
- remove the vacuum pump from the top of the engine and remove it upwards, as it must be removed when installing the pump;
Installation of the pump is carried out in the reverse order of the removal process, however, the following recommendations should be observed:

- install a vacuum pump. It is mounted together with a sealing ring, which is replaced with a new one. Insert the pressure plate into the groove of the shaft and tighten the bolt to 20 Nm. On fig. 453 shows a way to mount a vacuum pump;
- insert the oil pump drive shaft from below through the engine into the inside of the vacuum pump drive mechanism and press on the oil pump without gasket to the crankcase;
- tighten the bolts to a torque of 25 Nm;
