8274s must be pretty well built.
I found out why my winch has been jumping out of gear the last few times I worked it hard. The shaft of replacement motor I put in didn't have enough spline length, so the sliding gear that drives the winch was only getting 1/2 a tooth mesh with the gear it drives. :eek: , it would keep the shifter from going in far enough to detent (lock), so when the gear was torqued it would push the shifter out.
A little time with the dremmil and we're back in business.
I'm real lucky I didn't bust a gear... :)

Oh ya...the commutator was covered with tar or something, and the brushes were stuck in the holders...it still pulled like mad. :)
