Working on a 140 with no serial number tag. The engine number is visible. Is there any way to determine the year from the engine number? I know from checking several the tractor number and engine numbers have a big difference.
 
GM: The engine number is directly below number one plug, stamped on a machined flat surface. Yes those numbers are progressively larger than tractor serial number. 140 number 501 started off with engine number 65046. If you give me that number, I have enough of these recorded I can come close.

Secondly if you quote the casting date codes this will help. Every major casting on the tractor has a date code, day the casting was made. These are about 1/2" high digits, day and month by number and year by letter, with what looks like a round head, blade type screw cast between each of day month and year. Year codes are D in 58, E in 59, F in 60, etc. Those can be up to six months before tractor was built.
 
My engine number lists stop at '67. It is later than that. You will probably need to look for the casting date codes as Hugh suggested.
 
Jim: After the end of 240 production, 140 was the only tractor left using the C-123 engine. I think one can assume there will be a constant difference between tractor serial number and engine serial number of roughly 80,000.
 
Hugh,
I think that is a reasonable observation. It seems to track pretty well in the '63-'67 range where we have the numbers. If anything came along after '67 it disrupt the pattern, I certainly don't know what it would have been.

That suggests Super99GM's tractor is about 1975. I would still cross check the casting date codes for confirmation. 1975 was coded "Y".
