I have a HG-31 (not a HG-42 as I originally thought) with serial number plate removed from upper right side of bellhousing by a previous *&^@#$@#$!!. You can see where the old rivet holes are, but the plate is long gone.
Engine serial # is 1296239. Engine is IKX-3.
I finally broke down and ordered/received my set of parts and maintenance manuals last Friday and see that the frame S/N is an integral part of knowing what' was installed as OEM equipment on this thing.
Is there any set of records from the past that correlate engine S/N w/serial no. of frame?
Thx.

Idont know of any relationship between the two serials. A hercules IXK3 would be a correct engine for an Oliver/Cletrac HG.
Walter is correct and if I remember correctly Hercules had more than one set of engine numbers so that might help date it a little bit. The IXK was used untill early 1950. So your crawler is from 1940 to early 1950 as the rear early ones (1939) had IXA engines. Look behind the mag. There will be a casting date there when Hercules cast the block. The tractor was probably build 4-6 months after that date unless maybe if it was in the middle of World War 2. Does that help?
