1 Remove burrs on edge of mounting hole for the radial seal and clean mounting hole (arrow).
2 Inspect contact surface of the radial seal on the crankshaft flange.
If a wear groove from the old radial seal can be felt on the crankshaft, use the insertion tool with shoulder (repair position) for pressing in the new radial seal.
Using the insertion tool for the repair position ensure that the radial seal is pressed in by a further 3 mm.
