9231Re: [solectria_ev] Shift Happens! Could use some advice, or a replacement motor
- Jul 31, 2013If the bearing is spinning in the end bell, you can find a decent motor
shop or machine shop and have them sleeve the housing. This amounts to
chucking up the end bell, boring it clean, pressing in a sleeve then
boring it concentric with the end bell. This is not an uncommon problem
in the motor industry. When reassembling, you will want to add shim
washers and possibly a bearing spring washer. The helical gear can put
a significant load, pushing and pulling the shaft. It needs to be
assembled such that it doesn't do that.
JB weld and other compounds WILL fail.
