The Stovebolt Site Forums The Shop Area Engine Shop 1960 Apache 4X4 info ?

Guys, somewhere I have one of the old shop manuals for my truck, but I can't seem to find it. In the back of the manual it had a spec page that listed all of the specs for each model, like type of differentals, engine, transfer case, gear ratio, etc. Does anybody have one of those manuals, and can email me the info from that page? I really need the info on the drivetrain differentials and transfer case.
Any help would be appreciated! Thanks, Jack

Don't know what the transfer case for these was, but I'm pretty sure the axles were Dana/Spicer. Dana 44 front and rear for the 1/2 ton, Dana 60 in back and 44 in front for the 3/4 ton.

Eric, thanks for the post. I believe you're right, the front and rear dif are Dana 44's. I'm thinking the transfer case is the Rockwell 221, but i'm not sure. I know it was specified in the 1960 shop manual. Maybe someone will look it up for me, i've been all over the net looking and can't find it.

This is a page out of the 1961 supplement manual. The 1960 shop manual doesn't have any info on 4x4, and I believe the 62 supplement has even more info. picture
If your truck has the original running gear, it should have a Rockwell (Timiken) T-221 t-case, and a Dana 44 front axle with enclosed u-joints. The rear probably looks similar to mine, with a drop out center section like a F*** 9". I don't know that the Dana 60 had been invented yet, but I could be wrong. Check out my webshots pics and see if yours is the same. Do you have any pics of your truck? Hope this helps...

Big61, I finally found my book. According to it, my front dif is a Spicer 445F. It says the rear is a Chevrolet semi-floating Hypoid. The transfer case is the Timken T-221. Also, all it says for the transmission is that it is a 4 speed. It may be a Spicer also, but I don't know which model. If my book was correct, the 1960 4X4 was only offered with the 4 speed. Thanks for the help!

Yeah, the tranny would be an SM 420. You're probably right; I think it's the only tranny available in a 4x4.

If you have a 3/4-ton or 1-ton, the rear axle will be the standard Eaton H052 or H072. Drop-out center section, etc.

Big61, those are great pics. How much trouble was the changeout from the T221 to the NP205? Is the NP205 set up the same way with three driveshafts? From the pics, it looks like it bolts up to the same mounts. About how much does a changeout like that cost? Thanks

The NP 205 swap wasn't really a walk in the park, but its pretty doable. It kinda depends on how much of a fabricator you are. If a guy was pretty good with a welder and torch, it might almost be easier to build a whole new crossmember, instead of adapting the mounts like I did. I'll post a pic of the plates I used to get the 205 far enough up in the frame. Here you can see the final deal. The upper mount on the driver's side was just a custom piece of plate with web welded on for strength, which I don't have a pic of. It's a great transfer case to swap in--tough as nails, and pretty easy to get parts for. There's several different varities, most of which bolt up to the tranny. The divorced NP 205 like I have is out of an older dodge, I believe. I bought it from a place called Off Road Design and I'll warn you, its not cheap. I think the divorced NP 205 itself was around 800, plus shipping. I didn't have many options, though, as I had a T-221 with a fist-sized whole in it, a non-driveable truck, and a brand new driver's license. They have a ton of info on their web site about 205's and such. I don't know that you can adapt a 205 to an SM 420 tranny like you have, so that's why I went with a "divorced" t-case, which has 3 yokes on it. Feel free to let me know if you have any other questions.
