[AT] Replacing PTO Shaft on Ferguson TO-20

[H. L. Staples]

If it hasn't been done in a while this is probably a good time to flush the
differential housing with diesel and get all the crud out of the bottom of
the case. 

If the bearings are tapered roller then adjusting the pre-load with proper
shimming is in order. Probably about the same tension as on the front
spindle of a vehicle. Tapered roller bearings don't fair well when run loose
enough that end play can be felt. On the other hand not to tight either.

We replaced the PTO seal a on the Ford 2600 and its shaft has ball bearings,
so no shimming was required.

I'm about to replace the 1 1/8 inch PTO shaft on my Ferguson TO20 with a 1
3/8 inch. The old one is working OK, but leaks badly at the gasket so as
long
as  I'm working on it figured to upgrade. I've got the I&T manual # FE2, and
it
  seems pretty straightforward, just drain the fluid, and remove the four
bolts. I  assume using some type of liquid gasket in addition to the paper
gasket
provided  would be prudent (Permatex UltraBlue silicone gasket is what I've
got on hand).
The I&T manual says to adjust shaft bearings with shims to  permit shaft to
rotate freely, yet without perceptible end play. Is this  only for the
extension drawbar application (which I don't have)? Thanks for any  advice.
