Installation Notes and Tips

Confirm the shaft diameter, outside diameter, and width against the removed seal before installation. Inspect the crankshaft sealing surface and housing for wear, scoring, or debris, and clean the area thoroughly before fitting the new seal. Proper alignment during installation is important to avoid damaging the sealing lip and to ensure even seating in the rear seal bore.
