Afternoon all. Decided to strip and inspect my clutch plates yesterday due to a persistent clutch drag and almost impossible finding neutral when idling.
I have a 6 spring clutch with nyloc nut adjustment. The metal plates between the friction plates dont fit the clutch basket snug, theres almost like a back-lash between the two where the metal plates have worn against the basket. Is a tolerance acceptable or should they sit nice and snug over the basket?
The basket itself looks fine, just the metal plates look to be worn at the basket contact but are nice and smooth on the faces with no heat spots.
Ive been told to fit a 4spring clutch off a triumph, anyone got any knowledge of this modification?
Thanks
BSA fitted the Triumph type clutch to the twins during 1960. A number of sellers with supply you with a complete 4 spring clutch. None of the parts interchange between the 2 types.
I replaced the 6 spring clutch with a 4 spring version last year in my 1959 A10. I know a number of other local club members who have done the same and believe it is quite a popular "modification". As previously mentioned the 4 spring version was used from new by BSA from around 1960. The 4 spring clutch can be easier to adjust but in my experience getting the A10 gearbox in to neutral when idling is still difficult and is best achieved while there is a bit of forward motion before coming to a stop.
I have replaced both clutches on the A10 and the BB33 with 4 spring and SRM pressure plates. but you will need the correct clutch adapter for both .do not bother with Ebay SRM have the correct ones .I have found that TRIUMPH springs are much better in both and make for a very light action. also the cable routing can be a problem .
