Rear 3/4 is removed. Some stuff to run past you guys... (1 Viewer)

[DKM]

Rear 3/4 tub is off. Time to keep stripping the frame and get it painted. From researched threads, I'll first give it a good washing, grind it all down using a wire wheel/stripper disc/dremmel for small spaces. Inside frame with chimney sweep attached to drill. Go over with Corroseal. Then Rustoleum primer, then Rustoleum semi-gloss black. Eastwood internal frame coating. Does this plan sound okay?

Second, it looks like the PO bought the protective grease coating treatment for the tranny/t-case. Ha. This thing is a mess. Any ideas on the major culprits? Also, with the aluminum involved, it looks like past threads have recommended Simple Green (but you have to get the Extreme Aircraft Approved) and Formula 88. Any input or preference there to clean this up?

I think a scraper and a wire brush to start on the frame and driveline.

A parts brush (stiff bristles) and diesel to scrub of the grease build up. Put a big tray down first. Big cardboard box cut to be a few inches tall and lined with two layers of plastic.

You can use an alkaline oil-base gunk remover on aluminum, just keep an eye on it so that it doesn't soak too long. If the aluminum has a polished finish, the alkaline solution will pit it, but the transfer case dosnt'(didn't) so you have nothing to wory about.

You'll know when it's been in solution too long; you'll see bubbles forming on the surface. I've soaked 80 series intake amnifolds in 100%m, heated, purple degreaser for 30 minutes without any damage to the surface.

I asssume you aren't going to break the transfer case down and immerse it, so a wash won't hurt it at all.


FWIW, I'm a Ospho fan: Ospho vs Corroseal

That's a pretty rusty frame. I would consider splitting it and then getting it sandblasted.

I've always just used a steel scrapper, wire brushes. I try to keep the solvents to a minimum, but, painting it with something like WD40, MMO, and leaving it overnight can kinda help - it might have been baked-on with exhaust or engine heat. My preference is to use Comet to degrease, with a sponge, nylon brushes, green Scotch Brite, steel-wool, stainless steel wire brush - no dust to deal with, and a sponge keeps the mess contained off of the floor, and hopefully out of the gearboxes themselves. Wet / dry sandpaper can also remove rust and grease, like on the frame, with Comet.

trans and transfer look like most I've seen after 40+ years, it just happens

good pressure washer, with hot water, will clean things up
