Hmmmmmmmmmmm I’ve never actually seen a failure such as this… it looks catastrophic… I would seriously doubt JB Weld would be a viable permanent solution, that plate holds the entire motor on and the bearing square to the shaft, i doubt you could get enough JB weld on that to substantially add much strength… (but necessity is the mother of invention… and you really can’t mess it up more than it is if you can mitigate JB Weld form going everywhere and effecting either motor rotation or motor mounting)
Personally I’d ask Dex @torqueboards if he has a spare piece, and or who is the OEM of the motor, I originally thought TB was rebranded Maytechs but it doesn’t appear so…
I’d probably ask in this thread:
if someone has a blowed-up TB 6380 or any 63xx motor
the motor mounting/bearing housing end all looks similar from this pik… and I’ve had some good success soucing misc. parts from that thread…
good luck buddy…
EDIT: can you see or figure out what caused that malfunction? if it was simply a bad part, replacing it would probably solve the prob. but if your set-up somehow exacerbated, or caused that failure, you’ll probably continue to fuck it up till ya fix it…
