Hi All, I am working on a prime mover 1200 skidsteer that I received in parts. I cannot figure out what this part on the machine is, and the manual does not show it either. It looks like a shaft, riding through a bearing, that is attached to a solid block of steel within the chain housing. It is not hooked up to anything, and only rotates 30ー or so? Help? Also does anyone know anything about the engine? Per the manual it is a chrysler H-98, but I can find no info online about the engine at all.
