Revolution Maintenance

Hello, The Revolution was still able to be moved by hand but when loaded on the truck turning corners it was jerky. Did a teardown tonight on the hitch.

Found Water under the friction plate, don't think there should be this much moisture in there.

The friction plate and upper surface was fully cleaned and white lithium grease on the friction plate. The bearing post was cleaned as well, dried up the moisture under the friction plate.

Torqued to 80 ft pounds, operated the hitch and re-torqued several times as the thrust bearing seated. Only thing is using a 1/2 inch Torque wrench with a 1/2 to 3/4 then a 3/4 to 1 inch adaptors there might be some error due to slop in the the adapters.

For the record I can move by hand but it is much stiffer than before. Was torqued at 80 ft lbs when I removed it. The Cotter Pin was jammed pretty solid in against the castle nut.

Ok don't Laugh. I do not have a press or help so the most resourceful Engineer is the one that gets the job done. Use the trailer weight to press the bushing back in and push the hitch back into place. Custom milled 4 x 4 PT with a very accurate speed bore hole in the end.
