ring gear may have cracked loose and slipped too far back

Lets see:motor was running at some point, starter was making a grinding noise,rebuilt starter , still makes noise. =loose/broken ring gear, ring gear too deep.<br />measure from ring gear to block mounting bolts,, compare with bendix extended to starter bolts.

Re: OMC STARTER WONT TURN FLY WHEEL

normally: establish the rotation of the starter,disassenble, bead blast housings,clean and true armature, replace brushes,replace bendix,lube, assemble, bench test.<br />only other time youll get that noise is if the bendix drive is bad and wont lock up internally, most have 4-8 ball bearings that jam in the housing to lock it up for starting and allow fow over-run when the motor starts.
