I have been playing around with my PTO winch on my '78 FJ45 and I kept hearing a metal to metal sound. I figured out that the yoke on my PTO winch shaft has been hitting the crank pulley during engagement. I have a three groove pulley on the crank but I suspect that it would still hit regardless of which type of pulley was on the crank. Has anyone experienced the same problem and come up with a good fix?
