Can anyone clarify the correct way to put the rear wheel spacer (inner wheel collar) onto the rear axle. One end of the spacer has a larger diameter than the other and I was wondering if the larger diameter end should point towards the drive belt side or the muffler side. The previous owner of my 500i had a new back tyre put on and they made a bit of a mess stripping two threads on the rear swing arm and I am not sure if they put the spacer in the correct way. I am assuming that the larger diameter end of the spacer should point towards the drive side with the smaller diameter end pointing to the muffler, however, I could be wrong. Can anyone kindly help please.
