Note. The operation is shown on the example of engine 21124. On other engines, work is performed similarly.
Execution sequence
1. We prepare the car for work (see "Preparing the car for maintenance and repair").
2. Remove the camshaft pulley (see "Camshaft pulleys - removal and installation").
3. If the key has not been removed after removing the pulley, remove it from the seat.
Warning! When performing the following operation, do not scratch the working surface of the camshaft.
4. Prying the stuffing box with thin curved pliers, remove it from the seat.
5. We apply clean engine oil to the working edge of the new oil seal and press it in with a plastic hammer so that the outer edge of the oil seal is flush with the edge of its seat.
Recommendation. It is better to press the stuffing box using a special mandrel or an end head by 30 mm.
6. Install all removed parts in the reverse order of removal.
