Replaced both gaskets on my 1948 WD's final drive covers, and drained out the thick-black goop that was in there. After installing the gaskets, I filled to the level plug with Ford 90 weight oil, which I had in the shop.
Then I got to thinking that the Ford 90 wt is not an EP gear oil. I believe the book calls for 85-90 EP in the final drives.
So rather than take it all apart again, does it make any difference?
My guess is that the Ford 90 wt is fine for straight cut gears. I do use the tractor as an arena drag, so it does get some exercise.
