I am not aware of any hyd system calling for 90 WT oil, I believe 
someone needs to recheck what they believe here or read!

A automatic transmission fluid, the same as Case of the same era did. Of
course I have been using Case-IH hytran in everything which seems to work

help the situation but ideally it should have the pump repaired or replaced.
