Hi Team,
as the Trans magnetic screens are clogged so might be the T/Div. scavenge pump screen in the bottom of the flywheel/T/Div. housing and be why the T/Div area is full of oil.
George in later days there was a big upgrade of the Trans/Steering Pump suction lines, screens and filter system on most sized machines.
Prior to this to get the bottom suction screens out of the early machines you had to drop the trans oil--sometimes driving steeply nose up you could get away with only dropping some oil--now you can service them from above as you found.
The old style screens and their oil lines used to have oil leakage and air sucking in loose heat hardened hose connections etc. issues.
We await your screen crud pictures to see if it is linings or rags or ???
Cheers,
Eddie B.

Hi George,
no worries Mate,
the scan below, from my 1965 Cat Powershift Transmission School notes, and is representative of the Scav. Screen housing on powershift machines of the day.
The screen is on the inside of the small red arrowed housing in the bottom rear face of the Flywheel/Torque Divider housing.
Remove that small housing that is retained by the some 5 or 6, 3/8" dia., 9/16'' head bolts and check for a restricted screen
NOTE, if you have had the engine running and the flywheel housing is full of oil it may be HOT.
If the housing is full of oil then this would answer the slow starter motor cranking issue you seemed to me to have early on.
First drain the flywheel housing and check if it is over full as per instructions for checking for a failed scavenge pump given previously--be ready for excessive volume of oil if scav. pump is failed and/or the screen is clogged.
Cheers,
Eddie B.

For #3, as well as checking the part number, also get a comparable measurement from another machine, just in case the one you have is not the correct length

I wouldn't use the water in the oil reasoning. Sitting for that many years it is bound to have some water from condensation in the trans oil.
