Title: 1960 A10 Part number help
Post by: dstahnke on 27.11. 2019 21:22

Greetings all,

I'm attempting to build my first A10 1960 Super Rocket and then possibly a Golden Flash. I have a completely enclosed chain guard and I'm missing the two bolts that go through the inner primary case and through the chain case. Can anyone dig up a part number on these as I'm not seeing them in the parts diagram I attached?

Thanks in advance.

Roger did you make those diagrams? they are very helpful and way better than the old piece of cardboard i have in the garage.

Yes Mike, I did them for my own use but happy to distribute and share.

On the Draganfly Motorcycle website they list those bolts, if you have just the sliding plate then part number is 66-7523 and with the fully enclosed chain casae they ae 42-7520 I have a fully enclosed chaincase and those bolts are longer as they go through the rear chaincase and hold the front section in place as well as the sliding plate. Give Draganfly a ring according to their website they are in stock. Check those numbers in case I have got them the wrong way round

The reason for checking the numbers is my parts book shows the short bolts and gives the number 42-7520 but on the Draganfly website they list that number as for the long bolts for a fully enclosed chaincase and give the other bolts as 66-7523. I think 42-7520 is the correct number.

G'day Dave.
Now get over to Introductions and tell us a bit. How you became interested in A7/10's etc.
Nice job on the CB77.

In the technical section is the list from Stainless Fasteners that lists most of the BSA fasteners and their lengths.
Very handy when you see things that do not look right.
Back in the days of specialist dealers they knew these numbers but now days when there are only a handfull of dealers that cover every marque mistakes are all too easy to happen.
