Hey guys,
sadly this is not just a disasseble-clean-grease-reassemble problem because my motor is new and has not seen any dirt or water yet. I have the XF19C version of mxus's most powerful geared rear hub motor series.
The problem is that as soon as the motor axle is loaded (for example if I sit on my bike) the freehub becomes quite hard to turn. I can still ride my bike that way but the cassette spins so badly that while im riding the upper part of the chain loses tension and drops below the chainstay. When the motor axle is unloaded the freehub spins ok.
I have already tried to tighten the lockring of the freehub body which helped but did not solve the problem (chain still drops). If I remove the bearing which sits above to the freehub lockring (see picture) the problem disappears, but I am not sure if the axle is strong enough to handle the extra stress without the support of that bearing.
Do you have any ideas how this problem can be solved?
Thanks a lot in advance!
