Leo, If you know who the manufacturer is, it would help. A lot of older lifts may not be manufactured anymore, but may use a common powertrain or chassis. Like new Mastercraft are on a Caterpillar backhoe chassis or a Dahmer Forklift is on a New Holland/ Ford 545D Chassis. You can go back to the original OEM for the drive axle or steer axle and possibly get rims from this machine or Julio you might be able to get diagrams.
