Jeep CJ Dana 20 Transfer Case Part 2 - The Rebuild

- There are a few videos on youtube about the Dana 20 transfer case, but they aren't the same as the Jeep CJ Dana 20 or not helpful on how to put it back together. This video, although lengthy, covers all of the steps that you need to take to put the Dana 20 back together.
The overhaul/rebuild kit that I purchased is on Rock Auto. It comes with good quality bearings, gaskets, and seals. bit.ly/2QOjV99
If you need to replace any of the gears or inner components, these can be found on most 4X4 sites (Quadratec, Morric, Summit… etc)
Here is a section on Quadratec that has all of the things that are available for the Dana 20 on the market. Anything outside of this list will need to be found as OEM. bit.ly/3cI5D2z - ยานยนต์และพาหนะ
I watched both parts as a primer to my build… gonna have to watch again.. thanks for all your effort to share. Very helpful…
I had to watch my teardown video 8 times to remember where things went :)
Use Vaseline to install the needle bearings. Then put the gear in the freezer. when ready jut take out and install. and use Vaseline to hold the side brass in place. I used the 15/16 socket to slip in the back side to align the gear . After lubercating the shaft slide it in pushing the socket out .
Yep. Most of this I heard about after the fact. Sometimes I forget about the work smarter, not harder thing. :) Thank you for the insights. Everyone who reads this will benefit from it.
Here's a 'hack' for the needle bearings. Assemble the needle bearings into the gear and use a 15/16 deep well socket as the temporary shaft. You will need to shorten the socket to fit flush into the housing.
Once all the bearings and spacers are inserted and the 15/16 socket is in the gear, drop the gear in and push the socket out with the intermediate shaft. Boom!
Where were you 4 months ago when I was pulling my hair out? ;)
What a great series got a 76 cj to restore and the mechanical is so rudimentary it's nice to work on something that doesn't need a code reader to figure out and start
You did a great job on the t150 & Dana 20!
Awesome video. After watching both parts I feel fairly confident that I can accomplish this rebuild. Thank you very much
Glad to help. Reach out with questions.
Add sealant between shims around 16:00, shims and cover doesn't seal its self on the one I'm building you can see sealant residue. Also add sealant to any bolt that goes into case and is open, which is almost every bolt. Great video helped me sort out my box of parts, got trans and transfer case done today. Thanks for taking the time to make video
Appreciate the builds. I must not have filmed it but I used spray adhesive for the shims. Picked that up from an old transmission guy I know. If you’re going to use sealant, I’d make it s as thin as possible. The tolerances for the shaft clearance are so small and effect the foot pound about off the fattening bolts.
JWCG, i ended up having the same problem with the pin bearings and ended up using Vaseline to hold everything together. Thanks again for the awesome video!
I wish I had been educated enough to have used Vaseline. Probably would’ve saved me 2-3 hours of annoyance.
Really nice video - I did my Dana300 last spring. Man, I'm behind on my restoration. Well done!
You're never behind. Change the deadline, remove the stress level. :)
I was cringing a little when you were putting the rear drive hosing on without putting it together.
Thanks for the good video.
It's a learning process. You should've seen the part that I cut out where I realized it. Broke a couple things in the workspace. :)
I can’t say enough how important it is to RTV the front output shaft washer, I’m on seal number 2 before I figured it out…….
Funny how the small things make all the difference.
The video was very useful my Dana 20 rebuild is complete!
Thanks
Kind of gives you a sense of confidence, doesn’t it?
original shim pack will have to be re adjusted by adding or removing to achieve the proper preload
where you're now working with new bearings
Good video. On the intermediate gear needle bearing install I use a wooden Dowell. Cut to the length of the gear I get the dowels at hdwr store. Haven't tried a broom stick or shovel handle but if having broken ones around they may be worth a try
Brilliant! Great insight.
This intro is infinitely better than the old music. I haven’t watched your vids for a long time, just stopped by to see if the intro was same. Happy to see some have the better intro, sad not all have it. Was hoping to subscribe. Oh well...😕
It's a love/hate relationship. I personally love it but others don't. So i try to mix it up.
@@coolguy_CJ7 from what I have seen you have useful content, but I can't get past it. I'm restoring a 76 cj7 and if it was not in your videos I'd subscribe. I'm sure there are others who feel the same way. Sorry.
@@hgj2019 uh why don't you just fast-forward throught the intro? Why are you so petty lol.
@@jsf11fra nope. Not petty. Just giving my feedback. Life is too short to have to fool around fast forwarding bad intros when other channels do better. Just that simple. But bless your heart for being such a critic of my criticism!
@@hgj2019 If life is so short they you should be skipping all intros and get right to the main point of the videos. You make zero sense. But I already knew that
Thank for the informative video. Helpful a whole bunch. I have a 77 jeep cj5
Great. Now go rebuild yours. :)
Fantastic video. I will never look at a toilet roll the same way again! Weird about the intermediate O ring. Never seen one that needed to be sheared off to make a seal.
True on the intermediate O ring. Ifyou know of one that is square, let us all know.
Great build !!
Kind of a PITA but so worth it knowing that it is basically brand new now. :) I really hate needle bearings.
Question: When you torqued the yoke nuts did it improve the tolerances on the gears? I'm a bit worried about getting them up to spec.
Very much so. It got the bearings set correctly and everything spins freely. The first time I drove it, the shift from 4wd high to 2wd to N to 4wd low was almost to smooth. Worried I had missed something.
@@coolguy_CJ7 haha, thank you! Nice video by the way.
Thank you. Glad it helped.
Thanks for your awesome videos. I’m rebuilding a 76 CJ5 and you’re helping so much.
Quick question: my manual calls for 240 ft/lbs on the yoke nuts… can you confirm on your end? Thanks a bunch!
I believe that to be true. Really hard to get that much torque on a stand alone part though.
Yes indeed. I’ll torque it down once I install it on the T150, like you suggested. Perhaps engaging the 3rd gear.
Man what happened the old intro??? Take your cj7 all the way to 11. Always liked that I catch myself singing it at work lol
I only put it on about half the videos now to provide a little variety ;)
Thanks!
Knowing how much you plan to do to your CJ, I hope this helps with your journey. You will be in awe of yourself once it's done and you're driving it down the road for the first time and it feels solid as a rock. :)
GREAT THANKS
Glad I could help.
Hey JWCG! Can you confirm if gaskets did come with the Rock Auto Timkin kit that you posted? Did you need to order any additional items for the rebuild aside from the Timkin kit and various Stainless Hardware?
Thanks, Mike
Nope. Everything for the "Rebuild Kit" was included. Now there are a few things that you can't find that I'm aware of, like the detents, so don't lose those :)
@@coolguy_CJ7 Thanks JWCG! Really love these videos have watched them a few times. When i say a few, i mean al least 10 + lol ...
@@coolguy_CJ7 great video. I’m putting my Dana 20 back together right now, using your video as a guide. Couldn’t have done it without your help. Oh, by the way, every part is available from Novak. I had a broken spring when I took it apart, and ordered the springs and balls from Novak. Again, thank you very much.
Did the output shaft loosen up after you torqued the yoke? I noticed you said there was no end play, that’s how mine is. I have some more shims on order, but never torqued the yoke down.
It did. Just enough to be perfect.
Hey can u tell me the gear ratio of this case specifically ?
Great Video !
Gear Ratio is low: 2.03 and high is 1.00. 26. tooth input shaft.
@@coolguy_CJ7 Is it cool if u could send me the total lenght, width and height of the case ?
im currently working on a project that involves this transfer case.
Ty
👍
In the Process of rebuilding mine. Is it possible to install the the shift rods upside down? I wouldn’t think so because of the way the forks have to line up with the Allen key on the shift rod.. I’m at the beginning stage, but I can’t get the front shift rod to pull out and get the two gears to engage with each other. I can push the front shift rod into the case, but it won’t pull out enough to get the two gears to engage. Idk if that makes sense. A picture would make it easier to understand.

Ok I did
I need 1st reverse synchro assembly where did you get yours at haveing trouble getting it

Sweet baby Jesus those little bearings was horrible…… I replaced the intermediate shaft and the gears are as tight as a tick on a dog. Again thanks for the video any updates on that o ring that got shaved on install ? Mine did the exact same thing
Nothing to report. I think we're going to be fine. It's not a pressurized system so the shaved ring should do its job. Those needle bearings sure are fun. Did you use my toilet paper roll idea?
@@coolguy_CJ7 I sure did that and about half a jar of vasoline. I had a real pickle of a time getting the new thimbles for the shift bars back in.
@@ericbrasel9598 did you replace the thimbles? Id be interested to know if the replacements are good or not. And look at it this way, hopefully you only need to do this once. ;)
@@coolguy_CJ7 they was difficult to get in. I took some Emory cloth and knocked down the edges on them they went in put a little rtv on them. Very difficult not to dent them
Does your t case share fluid with the t150 trans?
Mine definately does. The only gasket that would fit had the openings for the ports cut into it. Some people don't think this is the case, but I'm happy for them to try and prove me wrong.
