FYI:- The parts book states that the 6 spring clutch for the Swing Arm A7 and A10 models should have 5 driving plates and their part number is 65-3857.  The part number for the springs is 66-3800.

Cor sorry Derek,

I should have re-read your previous postings and I'm confused now.  I don't remember coming across a 4 spring clutch basket with 10 slots.  Well, at least not one for a single row primary chain.  I'll check all my clutch spares in the morning and do a comparison.  I'm pretty sure all my 4 spring Triumph type clutch baskets have 8 slots.

I believe that some A50/A65 clutch plates have 10.

And in '64-'65 A50/65 BSA had their own 4 spring type that had plates just a tad different. Then went back to the Trihard type. DAMHIK
Cheers

Hi again Derek,

Well, I checked out my spare clutches today to find that the BSA 6 spring clutch basket has 8 slots and the Triumph type has 10 so I reckon that all you need to do is exchange your new clutch plates for the Triumph type.

Here is an image showing the difference between them with the appropriate clutch plate above each one.

thanks' that is it  yes it is the triumph clutch thanks for the info 

[morris]

thanks i also get a feeling that there should be six plates instead of five.

FYI, I've got 6 steel and 5 friction plates on my 4 spring clutch.
First and last are steel. It's light as a feather and never slips.
