Well, today's job was further inspection of the tranny and transfer case, which always for me starts with scraping off the crud. It was rock hard and only some of the large chunks came off with a scraper. So, out comes the heavy artillery. A wire cup brush on the angle grinder made short work of the majority of the crud, while it spread grime all over the back of my workbench/Chevy truck bed. And as an added bonus, partly due to it being an el cheapo Harbor Fright brush and partly because it is the nature of the beast, I got a free accupuncture session.
I didn't find any busted case ears, cracks, or otherwise job stopping flaws in the case, so forward march.Here's the tranny after the beauty treatment.
Here's what it looked like before.. Dig that grooovy adapter and the Chebby bellhousing from the Nomad..

� As long as I was in Transmission Mode, I decided to take apart the supposed 48 Cj2A case I had bought from someone down New Orleans way quite a long time ago. It had the parking brake assembly I needed for the 3A, and the tranny had the correct input shaft I needed ( I think) to transplant to the other tranny. So, this time I decided to be smart and not lift it by hand, since I recently put my scrapyard A frame up. I found my chain hoist in the shop that I had found in an Indiana antique store last fall, and hooked it up. Even though it is rated at only a half ton it picked the assembled tranny and TC up like�it was a loaf of bread. While it was hanging in midair I did some more accupuncture/cleaning. Sure is nice to have stuff at a convenient height.
No overdrive to remove this time, found out it was a 26 tooth bowl gear.Took the nut off the gear but even though it moved freely a little bit it didn't want to come off, so I figured it would slide off when I split the tranny and TC. I popped the shifter off the tranny and looked inside. I don't know how I would have gotten it off without splitting teh transfer off.. Special puller maybe?
Not every used tranny is what it appears. This one was all cleaned up when I bought it, and it had a bunch of red silicone sealer on the tranny/ transfer case seam, as well as the bottom cover. You'd think...someone had it apart and repaired it or rebuilt it, right?? NOPE....If it had been put in a jeep the way it was it would have been a disaster. NO Synchro dogs were in the syncro assembly. I have no idea where they went, but you could easily shift the shift ring back and forth and it went too far in both directions. Also...looking into the case I saw a single lone roller looking up at me from its perch besides the reverse idler gear. OOPSIE!! �I guess I shoulda known the red silicone was a bad sign. Anyhow, everything else looked pretty decent , just a tiny bit of rust was starting to form on a couple of gears. �By the way, there were no guts to the parking brake, either, so I still need to find one.I think I paid somewhere around $100 for the whole tranny /transfer assembly so I can't really complain too much.
I took out the 5 bolts that hold the cases together, one from the front, three from the back, one never installed, and had to use a pry bar to break the grip of the silicone. As I had hoped the bowl gear slid right aff as the cases came apart. Good thing I had wired up the tranny, as the rear bearing slid off too...but no harm done, and eventually it will come farther apart to cannibalize the input shaft out of anyhow. Now I could easily move the gearboxes to gearbox alley by Pintojeep until I get ready to rebuild one. Split into components they arean't too bad to move.
Just for fun I scooted underneath Pintojeep, perched on a set of wheel dollies in the shop (ya gotta avoid putting miles on such a valuable vehicle ya know) to see if he had a parking brake. It's been so long since I was under there I forgot what was or wasn't there.. Well, at least some of the parking brake parts were there.. I didn't see the actuating lever but it was pretty dark. There were shoes at least. �I'll check the pictures I took under there to see just what I have. Everything under there is going to be replaced anyhow, as the tranny is full of rust and the transfer won't fit the new overdrive.
That's as far as I got today. More later..By the way the accupuncture didn't work. I still have no desire to smoke, and my back feels like an elephant walked on it. �:
I guess my aim was off with the needles.
