Frequently Asked Questions

What are the dimensions and Honda reference for this starting-clutch gear seal?

The Japanese-made seal measures 25 x 33 x 4mm and replaces Honda OEM 91215-300-003. This seal belongs at the starting-clutch gear location, not the countershaft or crankshaft.

How many 91215-300-003 seals are included and required?

One seal is included, and one is required at this starting-clutch gear seal location on one compatible engine.

What installation checks help prevent a new oil seal from leaking?

Identify and correct shaft play, wear grooves, crankcase pressure or a blocked breather before installation. Protect the seal lip from splines and sharp edges, lubricate it as specified and install it squarely with the sealing lip facing the direction shown in the Honda service procedure.
