Engine ID?

Post15 Apr 2018 14:11

I've run across an unfamiliar (to me) engine, and wonder if someone could help ID it. Could it be an Austin 803 cc? Its serial number is 1G 926563 -- from that can someone tell when it was made and what it came in? I have some pictures of it which I could forward. I will be grateful for all help. Thanks. Ben M.

Hello Ben,
Further to your query regarding the ID of the engine you have I would hazard a guess and say that the engine plate number you quote,( assuming that the number is stamped on the engine plate on the offside of the engine block top) may well be a Gold Seal engine number. In other words the engine has been subject to a BMC factory recondition and would therefore have been issued with a number other than it's original one. Any A30, 803 cc or early 948 cc A35 engine would have the engine prefix 2A . A40 948 engines would have engine prefix 9A or 9AB.
However a sure fire way to identify whether it is 948 cc is to look at the nearside of the engine block (ie manifold side) and there you will find in the block casting the figures '950' which indicate it's engine size. If the block is a later 1098 cc item then this is identified by a plate, rivetted, in roughly the same location with the legend '1100' thereon.
Check these pointers first and see if any match up.
Regards.
David Lewis.

To my mind, starting 1G indicates a part number. But then there's too many individual numbers following. A part number would have a maximum of four. As Mike says, a photo would be very helpful.

Mike & Dave: The owner sent me an email with pictures of the engine. One is attached, as I'm not sure whether this will work or not. If it does, I'll post again and attach the rest of them.

Mike & Dave: I also located a website called austinworks.com whose owner, Rob Stuart, says he has an A40 van built in September 1953 that has an engine with the serial number 1G 899xxx.

It's a pre BMC engine. That explains it. Actually could be an Austin 1200cc engine. Precursor to the BMC B Series. Original Austin number system i'd guess.

Definitely 1200cc Austin motor .The 1G prefix is correct .A40 Devon and possibly A40 Somerset.
What the engine in the photos was used for I don't know ,those engine mounts not Austin.
