Yamaha YFM100 Moto 4 Champ ATV 87-91 ATV Starter

Yamaha ATV Parts, Starters for Yamaha ATVs.

• Affordable starters are constructed with longer-life bearings than OEM
• Many OEM starter motors have an unprotected output needle needle bearing on the outside of the output shaft's seal; moisture can and does enter the output cap of the electric motor and follows the armature shaft to the unprotected output needle bearing, which corrodes the bearing.
• The manufacture takes the extra step of installing a double-sealed ball bearing, with the output shaft seal on the outside of the bearing in their new aftermarket unit.
• This simple application of common-sense engineering does two things: first, the outside bearing is now protected from damaging water entry, and second, the sealed ball bearing is replaceable.
