2011 oset 16 36V it's looking like the chain is rubbing one of the motor mount bolts. Chain doesn't feel overly loose, not sure what else to check. Anyone any suggestions?

 

Thanks.

I've got hold of a manual and it says that I should check the motor bearings for free play, if the shaft can be pressed in to the motor at all it'll catch this mount it says. Impact wrench made light work of removing the chewed up mount, I've not go the whole way and removed them all and split the swing arm atm.

Not sure why it says I need to remove the motor to do this, I'm sure if I just remove the split link and chain I can feel for any play in the shaft? I'm not used to these electric machines. 

I've got same problem.

just fitted heavy duty chain upgrade & that exact mount has had some hammer.

It will be a problem when need to remove the motor.
