Exploded Diagram

[spottycat]

Hi. I have my 1961 A10 engine in bits to sort out all the usual problems. I think all sorts may have been done to it over the years so can't trust everything is as it should be. I have a Haynes Manual but wondered if there is a detailed exploded drawing available that shows all spacers, seal etc. so I can be certain. In fact, it would be nice to have that for the whole bike even though the engine is my primary concern. Does anyone know if such a thing is available please? Cheers, Chris

You can use something like the Draganfly website https://draganfly.co.uk/product-category/bsa/sparesparts-for-bsa-a710-b3133-c101112-m202133/
Click on the link, select what you want to look at and then select your model and year.

I think they were produced because there's an original 20" x 12" (approx) blow-up of a plunger A10 engine and gearbox on my late brother's shed. It probaly came from Pride & Clarke as he was apprenticed there in the late 50s.

The BSA factory parts book is quite useful and year specific and available on this forum. I think the Draganfly diagrams are based on the factory parts book.

The BSA Service sheets are the best source, they are all free to download from a number of sites.  For the engine you want:
203
204
214
215
There's also a Service Chart that is free to download.  MC 15 does the top end, I can't remember the bottom end ref.
You can download set of the A group Swinging Arm Sheets 55-62

I don't trust the Haynes - too many errors.  BSA engineers wrote the Service Sheets and they know what matters.
The Parts books are also free to down load, but beware there are a lot of subtle various by year so make sure you are looking at the correct year.

Please find attached "BSA Spares "A" Group" 00-5086. That is all you need.
