July 3, 2025Jul 3 im not sure about what parts to buy and what i need You have to count the teeth on any one of the blue gears, then pull the whole clutch off with the gears so that you can see whether it has a single keyway or the 4-way spline. You will also need some parafin to clean off the old grease and some lithium grease to regrease it with. It would also help to show the designation markings so that we can see what motor it is rather than the name of the biggest ebike motor manufacturer in the world. What caused it to break like that? You must have hit something pretty hard. Edited July 3, 2025Jul 3 by saneagle
July 3, 2025Jul 3 should the clutch just pull of it seems stuck The last motor (mxus) I dismantled had a circlip under the brass washers that needed removing. Also I needed to use two large screwdrivers to prise off the clutch assembly with a little bit of force. Dont lose the brass washers and pin/woodruff key under the assembly.
