My Ford 1900 4x4 with 2 stage clutch has a rattle in the PTO when under a moderate load. It sounds normal turning with out a load . It sounds like a bearing. I cannot tell if the noise is comming from the transmission housing or the rear end housing. The PTO shaft doesn't wiggle so I am guessing it is an internal bearing. The service manual doesn't give a real good diagram of the PTO shaft and bearings. Can I access the PTO by removing the lift cover. At this point I am just trying to find which bearing is bad before starting a majior dissasembly. Does any one have any ideas to make this simpler to detect.

Hey Bill, sorry for your problem.
I have not done this repair or opened the tractor up enough to get to pto inner mechanism but studied some of the diagrams. Here is some of my thoughts.
- When I opened the transmission cover and PTO shaft cover right in front of the operator seat noticed the bearings are huge and very stout looking on my 1700. They get plenty of splash lubrication so hard to see then having issue shorter that the life of tractor unless they are running real dry.
- you don't have ORC as momentum of the rotary implement can not propel
your tractor, so all you have there is an siding coupler.
- can you with engine off, transmission in neutral , cluch out turn or wiggle the pto a bit. what happens if you get a wrench on the pto pipe and try to turn it a bit (not too much force)... I'm taking your problem might lie in the pto shaft, it's spline to first clutch plate or something brocken in the clutch assembly.
-I do the above test with the clutch completely pressed in as well and compare and contrast the results.
-One of the guys here changed and ORC on his 1700 and had to remove the lift cover and additionally the the axle as well. his pic was taken with his cell phone so it was not the most clear.
-I hope no spline in the pto input shaft is busted either at the clutch or at the sliding coupler.
- looking as the diagrams it appears the short stubby PTO shaft might come out from the rear without taking cover off. Not completely sure. when you take the cover off in the back I think there is a bearing pressed there as well.
keep us posted. I hope you don't have do major dis assembly
