    Still working on the '62 Willys. Pulled the tranny and the xfer case out of it today. The tranny is a T-96. Was this standard for a '62 CJ-5? I have not been able to find out what the xfer case is yet. Is there a number stamped on it? If so, I should find it when I finish cleaning the 40 lb. of dirt and grease off it. Was the Dana 18 a standard or not?

    I noticed the front diff has a 25 or 26 stamped on it. Hard to tell. Is this the Dana model? I have not been able to find anything on the rear diff, yet, but it is a locker or limited slip of some kind or another. When one wheel is turned, the other one spins the same direction. Can anyone who is more familiar with Jeeps than I am help me out on what the rear pumpkin might be?

    The more I work on this thing, the more I am learning. I am quite surprised at some of the innovative ways that Jeep made the older vehicles easy to disassemble/re-assemble. I was trying to figure out how to remove the shift levers for the xfer case when, after I got a 1/2 inch of crud off it, I noticed the small bolt next to the case. Bingo!! One bolt out and the shift levers came right out. I am actually liking, working on this thing. Hope to have it in the hills soon.

    However, if anyone could help me with the questions above, I sure would appreciate it.

    Thanks...

    Hello eti, one of my jeeps is a '62 but it is a 3b, not a 5. My father in law was the original owner so im pretty certain this is the way it came from new. I'm also pretty certain that underneath is quite similar. In '61, they went to a model 27 up front. Dana 18, (or spicer) is the correct t-case. Mine has a t-90a tranny. Rear should be a dana 44, limited slip optional. A quick way to tell is the sides of the inspection cover will be straight. Good job finding the lock bolt for the pin that the Twin sticks turn on. A lot of folks get impatient and torch the floor boards. Let me know if you need me to check some other parts for you and good luck. This is, by far, the best cj5 site to be on and get info from. After reading this site for almost a year, I was able to correctly identify my new-to-me renegades 1 and 2. These guys are smart!

    Dauntless,

    I appreciate the quick comeback. Even though I grew up with Jeeps, I have never owned one. I have owned three Xterras, the last two being Pro-4X's, and they are amazing vehicles. But since they are also my wife's daily haulers, the vehicles have not seen a lot of off-road. We use them for winter trips to Yosemite, Tahoe, etc., but I have been looking for something I can actually get into the hills with and not care if it gets a scratch or two on it, or some Utah pinstriping as we call it. When this one showed up and sat in my neighbor's driveway under tarps for about 4 years, I made him an offer and now I have a project. I am new on this site and I agree that the people in here seem to be extremely knowledgeable. I am a senior member in another site, one that deals with all makes of autos, and I have helped a lot of people there. I built up a 1997 Chevy S-10 pickup and it would scream. Earlier in my life, I built up a 3-cylinder, 2-stroke Kawasaki motorcycle, and it was deadly. My goal was to start with a 400 cc engine and see just how many horses I could get out of it and still keep it naturally aspirated and street legal. Later on, I dropped a built-up 280Z engine into a BMW 530i. When I got done, I got vanity plates that said "ZMW". But I haven't done anything for a while and it feels good to get back into it. I just turned 65 and I am still kicking it, and this Jeep seemed to be just the type of project I had in mind. I will be asking questions as I go, so feel free to respond. My first question was a dumb one. I have been out of this for a while and it shows. It is coming back quickly. Take care. Your avatar looks great. I take it both of those are yours? I will lean on you for your experience!! (lol!!!) Take care and have a good one, whatever you are up to...

    T-96 never used in a CJ. Are you sure that's what you have? Can you post a pic of it to help us I'd it? Going from memory but iirc T-96 was used in 2 wheel drive Jeepsters.
    Is this a 3 or 4 speed? T-90 should be stock in your year.

    I will take a shot of it, but right on the side of it, it states that it is a T-96, and it is a 4-speed. That is why I was a bit surprised. I, too, thought that the T-90 was the tranny that was in it originally, from what I had seen and read. As I clean the crud off the xfer case, I hope to uncover that number, too, if it is stamped on it. Thanks for the comeback. It is appreciated...

    It is a CJ-5, too according to the dataplate on the firewall.

    Borg Warner T96 is a 3 speed and not a 4 speed.
    It was used for 2WD applications such as the Dispatcher jeeps.
    Similar to the T90, it has an unsynchronized 1st gear.
    The T-96 was never factory mated to a Dana transfer case.

    I'm going to guess that your jeep could be an admixture of various Jeep model components.
    Limited slip rear differentials were fairly common on some of the Dispatcher models.
    Is the rear carrier centered or is the carrier offset to the right ?
    A centered carrier likely suggests that the rear axle assembly is from a Dispatcher model.

    If it is a 4 speed it is probably a T98, maybe it just looks like it says T96? Also, can you post a pic of the data plate that says CJ5?

    Front differential is probably a 25, I think it was '63 or so when they went with the 27.

    Jeep began to use the model 27 front axles in late 1961 for a short period.
    Then they went back to the model 25 until mid 1963.

    The Dana 25 has a breather vent on the cover while the Dana 27 has it's vent on top the carrier housing.

    Hey oldtime, you the man! It took me quite a while to learn those axles and timelines. I would love to sit and talk jeep with you. As for eti, let me know if you need anything else. All jeeps are good jeeps!

    The tranny is a T98-1Z. After I got about 40 lb of crud off of it, I could see it. So, that solves the issue. Is this a good tranny or not? If not, what kind of issues can I expect? The xfer case is a Spicer, but I couldn't find a model on it. Maybe an 80? Let me know if I need to do something in particular to this while it is out of the vehicle. Thanks for steering me straight on the T-96 issue. I appreciate all the experience in here and you can bet I will be tapping it while I come up to speed. Check out the photos I took as I metamorphed a clump of crud into a tranny and transfer case. They are in my album What a mess it was...

    yep looks like a T98 for a 4 cylinder . you didn't mention what engine you were working with . that explains the 4 speed

    Very strong, durable transmission. You will never break it. It could wear out some day. Keep oil in it, shift slowly and it will last forever.

    Transfer case is likely a Dana-Spicer 18. This is likely where your service effort should go.

    Album?

    Your t-case is a model 18. You're a lucky fella, buy a Jeep and it has a T-98, which is heavy duty and you didn't even know it. Can I start hanging around with you? ;):coffee::hurrican:

    The engine is the 4-134 f-head. It was rebuilt not too long before I got the Jeep. Seems to be some seepage at the rear seal, but other than that, it appears to be tight and runs well. Carb needs some work, but once I got it wired up, I hit the temporary start system I had put in place and it fired up immediately. Of course, I had hand rolled the engine to get some oil to the parts pulled the valve cover to oil up what I could and put some Marvel Mystery Oil in the cylinders to ensure I could do this without breaking a ring or something.

    Glenn, I am not normally a lucky dude, but once in a while I hit it right, and yes, without even knowing it until someone lets me know. Thanks for letting me know. Seems like I did ok with this Jeep. It has some kind of limited slip in it. When I spin a rear wheel, they both spin the same direction. Any ideas on what kind of rear end is in it?

    I appreciate your help and the help of everyone who responded in here. Once I get up to speed on knowing my Jeep, I hope to be able to return the favors.

    Later..


    Are you retired military? I did a little over 20 with the Army. Started out working in MI, because I spoke fluent German and Japanese, but then traded it for a marketable skill -- prime electrical power production. Still doing it. Plan on going part-time when I hit 67, and eventually fading out of the workplace.

    Timgr,

    Thanks for the reply. Glad to hear I have a good tranny in this Jeep. What do you recommend as far as the Spicer 18 is concerned? Are you talking replacement, or are you stating I should replace it with something better? Please advise. I have the tranny out, on the ground, cleaned and painted, after replacing all cover gaskets and doing cursory inspections on the tranny, etc. Thanks for the comeback. Just out of curiosity, what do you do in real life since you call yourself a nerd? I have a lot of clients in the "Silly-con" Valley like Applied Materials, Intel, Agilent Technologies, etc.

    I will check it out, now that I know the difference and see what I have. Still trying to figure out what kind of limited slip rear end I have in this thing.
