OIL FEED PIPES.
« on: 30 June, 2022, 14:07:04 »
Hi,
New to a BSA so please forgive my questions.
Have a 1965 C15 S, which is 90% built when purchased so going through all to finishing off.
Correct oil tank, new pipes but not connected to engine, looked through all the manuals I have for info but not found anything definitive on connections, the engine pipe block has two pipes 5/16 and 3/8 diameters, but not sure which way round the pies connect, manual gives examples but states not c15t or c15s. So is there a standard way, flow from oil box filter pipe to which one on the engine and return from engine to oil box , what oil box pipes connect to what engine pipes ?
Hope that makes sense ?
Marc.

According to Rupert Ratio, if you have got a rectangular sump plate then the outer pipe is the feed and the inner is the return. However, on the later end-fed (crankshaft) C15's, they have square sump plates and the pipes are the other way round. I would have to double check but assume your 1965 S is the same as the standard C15.

I think the only difference between the 1965S and the standard C15 was the camshaft and roller big-end. The C15S should have a rectangular sump plate and, unlike the 1967 C15, the oil pipes do not cross over - that is, the outer one goes to the oil pipe output and the inner one goes to the back of the oil tank.

Many thanks for your help, seems the Rupert Ratio book is one to buy, would you recommend volume 1 as a good start.

I restored my C15 and other unit singles using the Haynes Manual and bought RR Vols. 1-3 purely as reference books although Vols. 1 & 2 can be used as workshop manuals as well. If the engine has already been overhauled then Vol.2 (Everyting but the Engine) might be more appropriate?

The Rupert Ratio Unit Single Manual's Volume 1 & 2 were on offer through the Star and discounted in price (and signed by the author if requested).  I use them for reference but they're also a good read, giving insight into the range of BSA singles and their development through the years of BSA manufacture.

there is more than just how to with the RR books, there is why and what to do to improve.
much more than just a manual.
