Mexican Hat duals on a 220 ?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'm in the process of installing Mexican Hat duals on my 220 project and have ran into a problem. The inside wheels are non power shift and the Mexican Hat duals that I bought at a former dealer's auction also had fixed or non power shift rims. To complicate matters the tires are 20.8 x 38 radials. I do not have enough space between the tires with this arrangement. Checking the sales literature, I saw the the outer rims were always power shift. I've located a pair of PS rims this afternoon. Has anyone ran into this? Will the rail to cast center locks from another brand of tractor work?

	Nothing is impossible if it is properly financed

	Calvin, I think that you could use the angled power shift style rail slides from any 7000 series tractor. please don't quote me but I bought some to use on my 220 wheels. Anyone confirm?

	I'm not sure about any other brand tractor mfg. but i would stick with the Allis Chalmers wheel rail clamps. Chad: you are correct. I believe any wheel rail clamp made by Allis Chalmers, used on a cast wheel center will be the same. Maby even the ones used on the die formed wheel centers, like D-17 series 3,4, 170 180 185 175 also. Calvin: I have also noticed that Allis Chalmers used power adj. wheel rims with the Mex. Hat castings. I believe you have discovered the reason why.
