Jim Williams' experience with a Pinto rear end.

Hi folks. As for the year of the Pinto rear end, it was already out of the car and they thought it was a '76? The axles were 1-1/8 inch at the splines. To install the ring gear I had to machine the long end of the carrier for the ring gear to fit. The Pinto ring gear faced the other direction on the short end of the carrier. I had to do some clean up machining on the ring gear on the mating surface's to get a machine fit, the bolt holes matched and I used grade 8 cap bolts, I choose to use allen head bolts and self locking nuts.

I had to put the carrier and ring gear in unbolted as the carrier is longer and they would not fit inside bolted together I used the Pinto bearing for two reasons, 1- they are bigger than the Cub's and 2- the carrier housing was not thick enough where the bearing fit to turn down to fit the Cub bearings. We turned the inside of the bearing cups so we could get the Pinto bearings in plus I had to make the bearing cup on the long end of the carrier shorter as there was not enough meat on the carrier to set the bearing closer to the ring gear.

Also machined the cup deeper, on the long end and due to the deeper bearings they are inside of the hole in the transsexual so the cup is stronger there due to the position of the cup. Had to use extra shims to get the right gear lash. I also made a cup plate of steel and bolted it on the outside of the short end of carrier cup to keep the bearing cup from breaking under stress. I also made the hole bigger in the axle housing as the axles were bigger and welded plates to the housings and installed wheel seals. I used a self aligning bearing plate with locking screw's instead of axle bushings and I made a small flat spot on the axles so as to lock the bearing plate to the axle. The bearing plates have grease fittings. I am well pleased with my setup and the tractor at 1150 lbs. rolls with very little effort due to the bearings on the axles.

The axle flange's are Cubs and I cut the flange's off and machine a hole in the center and machined a shoulder on the axle so as to be able to weld the flange on both sides and also true up the flange's. I installed some wheel studs in the flange's instead of the Cub axle bolts.

If anyone have any questions let me know, I didn't think to take any pictures. Hope this helps.
