Burman Clutch Chain Wheel Bearing Washer

Postby nomisimon » Mon Nov 16, 2020 4:48 pm

Happy Monday

The work on my G3LS continues: dynamo fully rebuilt and back (thank you Peter de Kremer of Rutland), the gearbox is back in with damaged or worn parts replaced (thanks AJS&MOC for advice and parts).

I just need to finish the primary chain case reassembly.

Whilst reassembling the clutch, I noticed that both chain wheel bearing washers were the same thickness; both appear to be the thick variety 12-10-4.

The 'thin' washer is only about 1 millimetre thinner than the thick one and the bike has been running with the thick washers. I realise that Burman / AMC used different thickness washers for a reason, but as I already have two thick washers and no thin one, can anyone tell me what difference it will make if I use what I have?

Or should I just buy the thin one?

Thanks

Update...

The thinner one is on order from the club spares shop.

Normally I'd expect to replace these as a pair, but the thick ones I have are in excellent shape.
