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° 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.
