I'm trying to get an old e trike going I picked up recently. Think I've narrowed the fault down to the motor, wheel won't turn backwards so think it's seized somehow inside and only moving on the freewheel. I have made a thread about it here but replies seem to have dried up so thought I'd start a new one with the problem I'm facing now - opening the motor. It's some Chinese 36V 250W motor, I'm assuming brushless geared:
The hub cover is aluminium and appears to screw off. It has 4 notches around the centre which look like you could get a tool on to undo, but I don't know where I'd get a tool for it. They already had damage in the clockwise direction as if someone's been doing everything they can to tightern it.
I imagine it would be like this one from Bafang, but no idea if that one would fit:
I've soaked in WD40 and tried hitting them with hammer and screwdriver but it's just messing up the notches and not moving a mil. So I was thinking about attacking it with a hack saw and then seeing id I can drill some new bolts through to keep it together again afterwards.
Just wondering if anyone has any last suggestions before I destroy it?
