Frequently Asked Questions

What size and Honda OEM numbers match the starter motor seal?

The large starter-motor body seal is nominally 60 x 1.4 mm and replaces Honda OEM 31206-286-158 or the superseding 31206-402-008.

Is this 60 x 1.4 mm seal the starter-to-crankcase mounting O-ring?

No. OEM 31206-286-158/31206-402-008 seals the starter motor body or cover assembly. The smaller O-ring that seals the starter nose where it enters the engine is a different part and must be ordered by the motorcycle's parts fiche.

Which classic Honda families use the 31206-286-158 starter body seal?

Applications include SOHC and DOHC CB750 models, CB900/CB1000/CB1100 fours, CB650 and CB500/CB550 fours, CB350F/CB400F fours, and the listed CB200, CB350, CB360, CB400, CB450, and CB500T twins.
