1981 CJ7 Restoration - 2020.04.13

While the ambient temperature stayed above 65F I decided to go ahead and paint the transmission. Using Eastwood Alumablast, I went to work on the masked and primed components and was rather impressed with the results. The Eastwood spray cans are promoted as "paint booth sprayer in a rattle can." I have no standard to compare it to, but I will say that it's light years ahead of what I can get at the local auto parts shop.

After 3 passes with the Alumablast, things are looking pretty good.

While I was painting, I figured I might as well get a few coats of satin black on the locking hub bodies.

Locking hub bodies painted and ready for clear coat.

I was debating whether or not to clear coat the transmission and decided against it. The Alumablast created a nice surface feel. It's not exactly smooth, but much less porous than the raw aluminum from before, I think. Well, time will tell. Maybe clear coat would've been a good choice, but too late now, I took the tape off.

What perplexes me is the design of the transmission drainage. The lowest bolt that attaches the adapter housing to the gearbox is the drain bolt. I mean, WTF??? Could you not have cast a drain hole and made a plug at the bottom of this thing? When you undo that lowest bolt, gear oil drains all over the bottom of the adapter housing and then onto the skid plate, which will drip oil for months if not years. I don't get it ?!?!?

Ready to be put back together, but I'm gonna let the paint cure for a few days.
