Bendix Gear/ Starter Problems 1984 Work Horse GT-1600 Tein Briggs

No, and I couldn’t even feel the crack with my fingers. The only way I knew it was there was when I sprayed electronic cleaner on it the crack stayed wet a little longer and showed the crack.

I have already put the starter back together after sanding the commutator and undercutting the mica.

I tested the starter and it spins nice with no noise.

All I need is the bendix gear parts which are on order.

I also went ahead and pulled the flywheel as I can see getting the starter back on with it in place would be difficult in not impossible.

I will clean the stator and back of flywheel before I reassemble.

I did not mention above I checked the brushes and they were not worn down beyond the max limits which I read is 1/4 inch of length from the center of the wires connected to them to the surface that contacts the commutator.

Any solvent like carb or brake cleaner ?

 

A bit late to the party, but ONLY electronic-safe solvents should be used. 

Anything that can potentially dissolve or soften the varnish that insulates the windings can ruin it in a heartbeat.

Compressed air and soft brushes only.

CRC makes a product called electric motor cleaner specifically for applications like this.

I hope what is shown above is safe… Says it’s for sensitive electronic components.

Sounds like you did the required reading Neubs... I wouldn't have replaced the brushes either after see the crack. Probably not a big deal but no sense in sticking brushes into it if that piece lets loose. 

Good idea to pop the flywheel and clean & check things out behind there.

You should be fine with that.  

 

 

@Bill D is this the one you're thinking of?
