955 12A 24V Starter

My starter stopped working. It spins, but the starter drive is not engaging with the ring gear. This is a factory Delco 24V inertia drive starter and SN 12A6341. I have good batteries and they're fully charged. It suddenly stopped working right.

I pull started the tractor thinking that would kick out the drive gear if it was stuck, but that didn't do anything.

Starter was rebuilt about 5 years ago by a reputable shop.

I will pull the starter in a few days, but I wonder what the problem could be before I do.

Hi,

most likely the inertia pinion thread is dry and so sticks back in the disengaged position. Some loose juice should see it work again.

The pinion lives in the flywheel housing and so is subject to clutch dust and moisture.

Maybe dismantle and clean out the starter itself, check the brushes and polish the commutator, and lube the armature bearings for a chance at some trouble free run time and starts.

Cheers,

Eddie B.

Thanks edb! It's a wet clutch on this one, but I may try to get an inspection cover off and spray it down...maybe if I remove the plate where the pony normally mounts.

your reply makes sense though.
