Removing
1. Remove the flywheel (see above, "Flywheel - removal and installation").
Warning! When performing the following operation, do not scratch the working surface of the crankshaft journal.
2. Pry off the stuffing box with a screwdriver...
...and remove it from its seat.
Installation
1. We apply clean engine oil to the working surface of the new oil seal and evenly press it in until it stops with a plastic hammer.
Advice. You can also press the oil seal with an ordinary hammer, using the old oil seal as a mandrel.
2. Install the flywheel in place (see "Flywheel - removal and installation").
