swing arm bushes
Posted: 26 Mar 2020 11:36
Hello -How much movement should there be between the bush and swing arm pin before fitting in the arm? ie how close is the tolerance.
When I stripped my bike for its overhaul I removed the bushes from my swing arm and a spare I had to see which tidied up best. The pin that was on the bike was quite worn and had bushes with a much greater mass of material than the other arm.
As I had ordered shiny new bushes from Mdina I did not keep either set of the old bushes as I seemed to be generating a lot of old worn stuff and don't have much storage - this was a mistake.
So new bushes came and the gap is way too wide for the worn pin that came off. There is a tiny amount of movement using the other pin, is this OK, will it tighten up when I fit in the arm - is some movement needed anyway?
What I should have done is saved the old oversized bushes from the worn pin and got them reamed to fit the less worn pin but once again you live and learn. I spoke to Mdina who do advertise an oversize bush but this is oversize on external diameter which we couldn't see much call for!
Any input welcome
Thanks - Duncan
