My 1941 has Ben sitting for about 50 years, got it running about 3 weeks ago. Put on about 100 miles, now I want to change the oils. I am thinking to drive it and warm up the oils in the trans and diff and drain them out? What would be the best lube to put back in? And is this a good way of doing it ? Just because it's been in there so long more would come out if it was a little warm. What do you guys think? Mike

Changing those oils is a great idea and well advised. Getting the oil warm is another great idea. You'll no doubt find that the oil will drain slow even if warm but that will help. I'd strongly suggest you refill with the specified 600w oil. You can get this from a Mobil Oil Dealer in your area. The 600w does NOT contain additives found in all modern 90w oils and 95/140w oils. Those additives will attack brass and bronze pieces within you assemblies.

I disagree with Mike. The 41 Transmission should have synchos that are compatible with the EP additives. I would use the 140 weight EP gear lube rather than the 600W steam cylinder oil. Mac VanPelt, who specializes in Ford transmissions, recommends the GL4 or GL5 gear lubes. I would go with the 140 weight.

I know I've still got a lot to learn, but I'm with TomO on this one. All my old Ford literature says 90w Winter and 140 Summer for the tranny and rear gear. 600 is for the steering gear box.... unless my literature is wrong? Best to all, Mike
There are more "barn finds" than barns.

I use 600w in steering gears, but nowhere else. It was devised to stay in Model A gearboxes base because they leaked otherwise.
