bit left over from wheel build ... ha ha

[Ewan 500 K1]

I have bit left over from front & rear wheel builds on a 500 four . .. a steel washer/spacer. Cant see it in the parts diagrams, but am sure it came from either the front or back axle... slightly complicated by the fact that the bike is a mongrel of 500/550/750 parts. Photos of this bit below.. anyone know what it is / where it should go

If it's not something from the areas of the spindle that are visible outside the wheel, then you'd need to look at internal bearing spacers.

I'm not currently familiar with these parts on that bike and don't know your level of knowledge so this is slightly vague.

If you bolt up either of the spindles with a internal spacer missing it will put far too much side load into the bearings and cause failure so you need to assure yourself that you have nothing missing from between the bearings of each wheel.

At a guess I would say it sits in the sprocket carrier, filling the gap between it and the swinging arm
