Fluids for 1958 Ford 941

[lonesomedove]

The tranny, hydraulics and rear-end have 3 drain plugs so 3 different compartments.
I was thinking of using a trans-hydraulic fluid for the tranny and hydraulics, and I'm not sure
about the rear-end. Also the drain plugs look like pipe plugs and have square ends on them.
The one for the hydraulics is on very tight, I'm afraid any harder and I will break it off, any
ideas how to loosen one?
Thanks in advance for the info

Have you tried an impact wrench?

I haven't but I was thinking of using some heat.

The transmission-hydraulic will be suitable for the first two holes, before using it in the rear end compartment verify that it is suitable for hypoid gears.... if not, use a hypoid rated lube.

I think the rear end is separate on those tractors. If so 80w90 should be used in the rear. Try heating or tapping the fill plug with a hammer. The drain plugs are pipe plugs with square ends. Heating them will do no harm. Make sure you can open your fill ports too.
