Crankshaft seals

Front seal

Replacement

1. Remove the small timing gear from the crankshaft.

2. Removing the seal when the engine and oil pump are in the car can be difficult without special skill.

In such a case, another method is to drill two holes on opposite sides in the shaft seal, drive in two screws, and then pull out the screws using the grippers along with the seal. When using this method, care must be taken not to drill through the oil pump housing.

3. After you remove the oil pump from the engine, the seal can be knocked out without problems

4. Before mounting a new seal, clean the seat in the oil pump.

5. It is necessary to lubricate the seat and the outer edge of the seal with oil. This will greatly facilitate installation. It is necessary to take a tube with a diameter less than 0.5 mm of the diameter of the seal and hammer the seal into the socket, making sure that the seal enters evenly. This is done much more accurately when using a press. Then there is no problem with the distortion of the seal. If there is a steel ring, then, accordingly, by supporting the nest from behind, try to press the seal using a large vise. After installation, it is necessary to lubricate the lip of the seal with oil so that it does not start running dry, as this can damage it.

6. Then install the crankshaft gear.

Rear seal

Replacement is possible after disconnecting the gearbox.

7. Remove the flywheel as described in point 28.
