incorrect part book

[bsa- bill]

I noticed while I have the timing case covers off that for the second time I have managed to install the bushes for the idler gear the wrong way around.
I did this with my first bike and thought I must have got the bushes mixed up, the mistake became noticeable when the dynamo drive section filled up with oil which began to leak out past the dynamo cork, I have an SRM belt drive in there, testament to the quality of this belt drive that it continued to drive the dynamo even in oil.
Anyway I changed the bushes around after checking with my mates A10 that was in pieces at the time, the outer bush has a scroll that only comes half way through and scrolls the oil away from the dynamo section.
I could not understand how I had done the same thing again until I looked at my spares book, the spares book has the bushes the wrong way around.
There are four bushes the same 67-0686 three for the camshaft and one for the inner idler gear (inner as in the crankcase) the outer bush for the idler gear is 67-0286  and goes in the inner timingside cover,
Hope this prevents someone doing the same
