Horse Newbie 7,225 #26 Posted May 7 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. 1 Share this post Link to post Share on other sites
Horse Newbie 7,225 #27 Posted May 7 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. 1 Share this post Link to post Share on other sites
Horse Newbie 7,225 #28 Posted May 7 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. 1 Share this post Link to post Share on other sites

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. Edited May 8 by Handy Don 1 Share this post Link to post Share on other sites

CRC makes a product called electric motor cleaner specifically for applications like this. 2 1 Share this post Link to post Share on other sites

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. 1 1 1 Share this post Link to post Share on other sites
