trans can use either 80w90 gl5 oil, OR UTF oil meeting the m2c134 spec.
diffy can use the same as trans.
Hyds can use UTF fluid meeting the m2c134 spec OR AW32/46 fluid.. however, I STRONGLY suggest against using an aw type hyd fluid inthe hyds, and instead suggest the UTF. The pto shaft passes from the rear esction thru the hyds, and many times the oils will mix.. thus the aw hyd fluid will thin the gear oil, and have less extreme pressure protection.
for that same reason, many people run UTF in all sumps.
for the crankcase, I like a 15w40 c rated oil. oil bath air breather uses same oil as crankcase.
if in arctic weather, for sure use the utf in the rear sumps.. and perhaos a 10w30 c rated oil in the crnakcase.
if you ar elucky enough to have power steering.. it will eat just about anything.. ATF, PS fluid, hyd oil, 30w engine oil, 10w30 engine oil, or utf. UTF is reccomended.
don't forget to lube yer steering gearbox. originally it called for 90wt gear oil or 50w engine oil. I prefer 0 or 00 ep grease.. so did ford in 62 when it put out a service bulletin to change to 0ep grease in the steering boxes to combat leaky sector seals and dry thrust bearings..
