have an ex-200 just seeing what everyone uses in there final drives? thanks
We used TO-4 SAE50 in our Hitachis. Gave us much better results than Hitachi's recommendation of EP oil.
I second that vote for TO-4 SAE 50, runs cooler, finals live longer, and as an added bonus, it don't smell as bad as 90W when you do have to work on them!
i wish i would have known the to use TO-4 50...i used GL-4 90wt
