Hi All,
New to EMTB world bought a very clean (not always a good thing read on!) 2017 Mondraker E-Crafty with the Gen2 75nm Bosch motor a few weeks ago, ive done 300 miles in past few weeks and really enjoyed it!, not having experience of E motors in general i wasnt sure if the motor was noisy but its certainly started to get worse so my mechaincal sympathy opted to strip and replace bearings, ive already done the rear wheel bearings and suspension linkage as it turns out previous owner was fond of jetwashing, as above clean isnt always good if done wrong!
Anyhows i got the Mega kit from Ebikemotorcentre.com (great service) and pulled motor apart last night, it was much more of a fight than it should of been due rust on shaft/bearings, ive found the freewheel/clutch gear (think its called?) as per attached picture below is toast, anyone help with good replacement? or have dead motor that i can harvest it from ?
Failing that i can look at machining it back and fitting a press on sleeve if someone can supply correct OD, not sure if there is enough meat will have to speak to my local engineering shop but it looks possible. I wonder if there is a gap in the market for such a service if this is common and new part unavailable..hmm
