1956 Minn Moline 445

The engine in your 445 is basically the same as those in the 4 Star, Jet Star, Jet Star3 Jetstar 3, Big mo 400, 500 & 600 as well as the brown uni tractors. The piston/block/head/rods assemblies from the later (overhead valve) V type uni tractors will also fit but you may have to plug some holes etc. Not all parts will interchange directly between these engines such as the early ones must use a felt type rear seal while the later ones use a rubber lip type rea seal. The early ones have a spiral cut into the seal surface and if you install a lip type seal on them it will be destroyed very quickly. You can use a late crank in a 445 engine and then use the lip type seal.

The engines from the 335 and U302 also have some parts in common with the 206's in the 445's.

Later engines use a 3 bolt type starter which uses a different ring gear on the flywheel then the earlier one bolt starter.

If ask about specific parts, someone on here can help with possible sources.

Hope this helps.
