this subject might of been pounded into the ground but i have only had my raptor for about 6 months and i was wondering what this bearing dose and what happins to it. and how do u tell if the bearing is gone

 

that one way bearings on the starter...u are suppose to start in neutral not be in a gear with the cluch pulled in becouse the bearing only spins one way and if the gear engages a lil it will spin the bearing the wrong way and put dents in the bearing ...or if it back fires when u start it it will do that same...i put a L&a design bearings in mine ..it spings both ways and have back up springs on it if one fails

u can tell if ur bearing is going bad if it free spins or clunks when u start it...when u start it let go of the starter quickly when u can tell its started or it will damage it from the power of the engine
