[AT] 90wt oil

[Mike Sloane]

I can't speak for other tractor brands, but I know that the manual for 
the Ford 9N/2N/8N calls for 90 weight in the transmission and final 
drive. And the hydraulic pump is (unfortunately) pretty much integral to 
the final drive. That being said, it should be remembered that the Ford 
N used pre-WWII technology right through to the end of production in the 
early '50s. And in 1939, manufacturers had few choices of 
transmission/final lubricants. In the early Farmall H and M "Lift-All" 
hydraulic systems, IH recommended 30 weight engine oil, even though 
Hy-Tran (essentially modern hydraulic fluid) was commonly available and 
used in the Cub and Super A/C "Touch Control" systems.
