Diesel forty

The starting engines on all the three lungers will interchange. The D 40 parts book shows 3 different air cleaners and manifolds depending on serial numbers. The early were like the D 35 and the late same as RD 6 and 3 cyl. D 6.

Thanks mate
my serial no is around the 1100-1200 mark I think I can check and get back to you?

Hey guys
The serial no is - 3G1166
Any info is appreciated
Cheers

I could direct you to a diesel 40 parts machine in Michigan if it would help, I don't think the pony was there

The starting engine air cleaner was the same (2B3733) from 6E901 D35 thru 3G1434 D40, but plumbing was different. Effective with 3G1435 D40 the direct mounted air cleaner (3B726) runs clear thru the 2H series. Also into the 9G D7 and 1H D8. The manifold and carburetor are the same from 3G616 D40 thru 2H1421 RD6.

Would anyone have a photo of a machine with the correct air cleaner assembly for Dalby's Forty pilot motor to help him out so he knows what to look for.

Also Dalby after talking to you the other night I seem to remember Bruce Carey from Nobby showing me his RD6 with the same water leak behind the valve springs as you described with yours. I wonder if others have experienced this same problem. Probably a spot on the water jacket where derbis accumulates resulting in a rust pocket. The way most of these machines have been abused over the years it it amazing there is anything left of them.

Hey guys
Yeh Andrew i recon your on the money it seems to be leaking around the bottom of the water jacket on the back cylinder over the years built up with mud etc she has got a bit thin in there.
Ive been told that they are the same pilot as the d6 and d7 just with a different timing cover to take the crank handle through the bonnet?
I havent done any research on this myself but gives me a bit of a lead!
Shes very hard to get these bits here in Australia unfortunately.
Thanks for the other info and part numbers guys appreciate it, it will help me try find something.
Steve i would be interested in the forty you know of that might be parting out, if i could just get the air cleaner i could make the rest of the pipe work if i had too
Thanks again

If you can find a parts book it is easy to see just what you need. The easiest solution is to update to the direct mounted cleaner on top of carb. One of those should be easy to find with the carb top adapter.
