| Twin City Tractors & Parts Identification Using Casting Numbers |
Minneapolis Steel & Machinery Co. had a simple and effective way of identifying the cast iron components on the different models of successful tractors they produced during a lengthy 30 year production run. Excluding the heavyweight lineup there were several popular models made from 1918 through 1938.
All cast iron TC engine and chassis parts have a two letter prefix in front of the casting numbers. There are many combinations of part numbers following the two letter prefix on castings that can be explained in greater detail in parts manuals. If you memorize the first two letters from various models you can identify a cast iron Twin City tractor part off of an auction rack or a salvage yard parts pile anywhere, anytime and know if it is an engine part or a chassis part.
1918 - 1935 twin cam series including 12-20 & 17-28. Cast iron engine parts numbers for these models begin with TW. Chassis part numbers for baby twin cams begin with TY.
1920 - 1935 big twin cams including 20-35 & 27-44. Engine part number prefix for these models are AE. Chassis part numbers prefix is AT.
1926 - 1938 21-32 engine prefix is FE. Chassis prefix is FT.
1929 - 1938 KT & MT engine prefix is KE. Chassis prefix is KT.
KT & MT models used the same 283 ci. engine. There are a few dedicated chassis parts that make the MT different from the KT and will have an MT prefix on them.
1934 - 1937 model J was designed by Minneapolis Moline after the TC-MM merger and used an outsourced Waukesha engine. MM did retain Twin City prefix ideas making the engine JE and the chassis JT.
