I rebuilt my 1973 cj5 jeep T-18 transmission and my dana 18 tranfer case i never think I could do this. If it wasn't for this video I would never tried looks very complicated but it wasn't just because of this video and it came out excellent I have 35 miles on my rebuild and it shifts excellent thank you now going on 700 miles still going.!!!
I have watched several different videos on rebuilding T90 and this one is the best and most complete. Thanks.
Well done. I will be using this as a reference in my own rebuild. Mostly because I would have no idea what I'm doing without it. Thanks for taking the time to make it.
I have ZERO automotive experience, but now I feel like I could rebuild a transmission. Great video!
forget about it if it's a modern one. there so fuking complicated and crappy.
I rebuilt my t90 about 5 yrs ago from this video. Still goin strong. Thanks for the time of making this
I recently ie 8 days ago ,i got the 3 Speed Gear box of my Mahindra & Mahindra CJ500D rebuilt.
I will be testing it on Monday ie 22 Aug 2022.The most important point is , Engage the First Gear only when the Vehicle is on Stand Still.Never shift back from 2nd gear to First on the fly.
An Awesome Assembly by you 👌👌👌👍👍👍👍🙏🙏🙏🙏
BIG THANKS! Great video. Couldnt have rebuild my old gearbox (which had been sitting for 30year with water in it) without your video! Did it step by step according to your video last night.
Very nice. I have the T96 with OD, and I also have a complete series on how disassembly, assembly and how they work. Thanks for the video!
I’ll have a look 👀 sounds good.
It's been two yrs since I did this. My box is installed tranfercase back on .I am so thankful you made this video. Although I have not driven it yet I'm almost ready ,fuel tank & front brake slave cylinder to go then me & my Willey's will have a good time. Thank you so much.
Great video that builds confidence on this project.
I found your video while looking for information on a T98A BW. I have to say you made this informational, and very entertaining as I watched the entire thing while not even having a T90. Thanks.
+Sporkamus Prime much appreciated 😀.
Hey Mr. Shinitzl, I have now rebuilt my Dana 18 and my T-90 following your righteous instructions. So cool what
you have put online for us. Thanks.
:) excellent Lenny, I'm sure it was satisfying! and always appreciate the kind comments.
I've watched a number of how-to videos, but this is one of the best! Informative and Entertaining. Super job!
much appreciated friend :)
Thanks for all the tips. Making rebuilding my T 90 a little bit less intimidating. Good video.
Super helpful. I spent two evenings slowly going through this while writing myself instructions as I stepped through the video with screen captures trimmed and pasted into the document for each step. Thanks for putting this together. Much appreciated.
Just finished the job. I scored - you got the assist. Gracias!
You’re explanation was complete and thorough. I have many parts books and “hearing” your step by step dissection gives a novice confidence in attempting
this renewal of a T-90 without causing a mental break down :-) I have a T-90 now that I will try out and enjoy the results. Thanks again.
Nice work... I just inspected a Hubbard PTO on my T98. Replaced seals and straightened a bend shift shaft... Works great, just see in my video...
Thank you for the fantastic job you have done with this video. It has made my T90 rebuild so much easier. Your time and effort in sharing your knowledge and expertise is very much appreciated.
I don’t have this trans, but this rebuild video is crazy good. Nice work!!!
Just found this, great info !
Thanks to this great video, I was able to rebuild the shift tower in my CJ-2A in 30 minutes with $20 worth of parts. The rest of the transmission is fine (for now) and shifts great!
Very good. Thanks for sharing. I suggest those interested view metalshaper's t90 build also.
Thanks for the great video! Helped me rebuild my 46 CJ2A's T90!
Although I am very familiar with engine and rear end rebuilding, I had never tackled a transmission until about 10 years ago.My first trans rebuild was an automatic from an 86 Pontiac Grand Prix and I was scared spitless digging into it, totally afraid I'd screw it all up somehow. I was amazed at just how easy it actually was though and have since rebuilt a Borg-Warner T-5 from an 83 Pontiac Firebird as well. Your rebuild videos sure would have been a huge asset back then. Great stuff and keep it up...Liked and subbed.
Great video. I'm rebuilding a T19 and it is similar. Your video is very helpful.
it's nice to see a fellow fallout fan who also turns wrenches.
glad to know I'm not alone.
did you get her rebuilt yet?
Still working on it. Have it all apart and finally got the case and other bits painted. Hoping to get it back together this weekend!
Great job!!! Thx from Germany for showing your rebuilt! :-)
sweet glad to see ya back thanks Ric
Great video looks like fun to learn.Keep up with the how to and Thank you.Will be watching
Good job on the video. Very helpful!
Awesome video. Very much appreciated!!!
Love the positive vibes. This video deserves a better thumbnail!
Thank you. Any suggestion?
@@ShnitzlHaus I'd get a good pic of it with the top off where you can see the side of the case with the 2 big mounds on it. It's kind of an identifier for me at leas for a T90. Then maybe some text on the picture that says "full rebuild" in the top left? Best of luck!
I’ll see what I can do. Thanks!
This is amazing man!! thank you so much, I will be using this soon.
Awesome job man. Im about to do mine along with the dana 18 transfer case. This helped out a bunch. Thanks!
great video, answered all my questions. to the point A+
Great video.
You sound like Jax Tellar from Sons of Anarchy
Awesome work, thank so much!
Excellent video. well done!!
How do you get the poppet balls and springs to seat when the shaft goes in?
Very well done. Thanks for doing this!
I apprecciate the time spent on this vid.....I have seen ALOT of vids and this is very well done!!!!!!!
You should feel good not only having a nice new trans for yourself, but also that you have helped others.
Thank you
You can reinstall the top gears when the trans is mounted to the bell housing. Just push the syncro as far forward as you can, slide the 1st/reverse gear forward (to the neutral position), and if you curse just right, it will eventually slide in...
Truly great video. Very well explained.
Wow man. Great job.
Seriously excellent.
much appreciated.
Only one problem. You made a mistake on the rear output bearing. In the video you put it on backwards. You put the snap ring on the outside, but in real life it has to go on the inside closest to the transmission. The bearing seats into a cutout in the transfer case almost 3/4" and rests against a shoulder machined into the case itself so the snap-ring groove on the output shaft NEEDS to be closest to the transmission. Wish I had known the BEFORE I had it pressed on the shaft
I will have to check this out, I dont see it as an issue the snap ring should be removed before you assemble the transmission to the transfercase. my stock bearings that I pressed off before rebuild did not have a snap ring groove.
I've rebuilt several of these, and the orientation of the bearing is not critical. It is easier when the snap ring groove is oriented towards the transmission, as that leaves the filleted edge of the bearing facing rearward for easier transfer case indexing. Very well done, ShnitzlHaus.
My T90 fell apart during install, don't ask LOL, your video saved my A$$!!!! Thank you so much!!!!
When installing the bearing on the main shaft you put a snap ring on the bearing. On the picture of the exploded view of the T90 there is NO snap ring mounted or listed. There was no snap ring mounted on my bearing when I disassembled my T90. I even think that the snap ring prevents a good assemblage of the T90 to the Dana 18 transfer case. ??? Otherwise, a good guide. Thanks.
Tomorrow I’m going out to buy some paint and last minute tools to assemble my trans and hopefully it will be together in the next day or two
Thanks, great job
Excellent video!
Thanks from Mexico, I will start today and if I have any questions I hope you can help.
Sergio Velten forsure! I am confident you will get it done right.
obviously i need a complete rebuild kit as well
Great video.
thank you Joel.
And then again I want to thank you is most of these guys are a joke and you are awesome
my issue is how to remove the mainshaft? can you explain, did not see it in your video. you show it when is out. I appreciate it!
Hi there. Just completed my rebuild and this video was really helpful. (I couldn't view it using Mozilla as my browser but it worked fine on Explorer). The tricky bit is refitting the gearshaft. Also a bit puzzled that the rear bearing can drop out of alignment when the assembly is completed as the gearshaft can separate - but maybe this will be resolved when its refitted to the transfer box?
GlynBryan exactly, once you get the transfer case bolted up it will keep all the T90 gears in place. :)
Great video, complete and very informative. The one question I have is can I still retain my oil collector if I’ve upgraded to the later model year T90 cluster gear with the lower first and second gears? Third gear has 35 teeth on the cluster gear as opposed to 33 on the original cluster gear.
I know this is a year old question,but may help someone about this now,willys must have thought the oil slinger wasnt really necessary in the later T-90's,they deleted it,but it would be the rebuilders decision to put it back or leave it out,if you leave it out,dont forget to plug up the two bolt holes that retain it!
You’ve got to remove that snap ring off the bearing that goes into the transfer case where the Pto gear slides on or it won’t seat properly
awesome vid! where did you get the rear plugs? part number? my shifter rail moves so far back, it keeps popping the right rear plug out.... did you have this problem too?
que buen video..amigo..what a nice video my friend
:)
Thank you for this video and the video of the dana 18 transfer case. I am in the middle of rebuilding mine. I have them at the machine shop getting dipped so I can paint them. Can you share how you removed the bearing from the main shaft in the T90? I am going to have to buy the tool. I have a press.
you can use a puller, press or drift punch. just be smart about it, don't mar any surfaces so use soft jaws if its held in a vice. if your pressing make sure everything is coming off straight. puller or press would be first choices.
First I appreciate the effort in the video you did a great job. However, no one talks about how to remove the oil collector or the main drive gear. I know you did say this video was not going to show that and I noticed you did not install the oil collector. Did your T90 have the oil collector when you did the dis-assembly? If you have the oil collector its impossible to remove the main drive gear. I am sure there is a method to this (much like removing the flywheel from the 226 so you can get to the bolts on the bellhousing), if anyone has or knows the trick please let me know.
I love my Willys but I have to question some of the Engineering :)
+yffrules Thank you, to remove the oil collector you must essentially pull apart the transmission, funny but true its one of the last things to come out with the main drive gear. abbreviated (for a general idea), you get the main shaft with all the upper gears/synchros out, you then drive the lower cluster idler shaft out of the case - this allows the cluster to lay on the bottom of the transmission which then allows you to remove the main drive and oil slinger. the T90 is a puzzle but a relatively small one. my T90 had a oil collector but it was very rusted out so I opted not to use it, its a very debated topic. essentially the oil collector would help lubricate the upper bearings should you run low on transmission oil - either forget to check the level or because of the nature of the T90 and Dana 18 sharing oil on a steep incline the transfercase might take on more oil leaving the T90 with less then optimal fluid. to open up another can of worms you can run a full gasket mating the t90 and dana18 to stop the sharing of oil, just make sure you fill them individually! anyhow "Novak conversions" online has a great write up on how to disassemble and assemble the T90
Question: I am stuck on how to remove the Front Bearing Retainer Oil Seal! can you share your experience also, if there is video on DISASSEMBLY I would totally appreciate!!!!!!
Thanks!
awesome instruction video! when are you doing the t-18? my t-19 is on the work bench :D
My 1971 Scout 800 B has a T90 transmission. I have a question for my little Devil Box.
At 22:22 minutes , the video states to place 14) needle bearings that come with the kit. When I place these , there is not enough net area for one shaft to mate into the other..It seems I need 20)+ smaller diameter bearings. As well , these bearing need to be approximately 5/8" long in lieu of the 3/4" bearings provided in the Novak kit. Could someone advise what bearings I need to purchase and place into this monster? Another aggravating item , my cluster gear is reverse hatch direction from anything I can find available. Thanks for any help..! Great video !
Hey Raybone, the T90 came in various models. I'm not fully educated on all of them but maybe you have one of the "T90C" or "T90J" I am fairly certain that would be your issue as I believe they all varied in gear ratios etc.
rebuilding my t90 ? should the cluster gears fit very snug incase it rotates but its stiff has new washer & thrust wahers too
I recently completed a rebuild of both my transmission and transfer case using your videos (very helpful)
I haven’t installed them on the Jeep - just added oil on the bench and I am getting a very bad leak where they meet together
I have some pictures of the area -
Any thoughts?
Thanks in advance
Muito bom o trabalho , muito bem explicado , obrigado.
Thanks
You don’t need the oil collector it was eliminated in the later T90 transmissions
Thanks uncle
You’re a fn boss!!
thanks, great video... subd
Hi - when was the last time this was viewed? I've tried to watch it several times but it won't load/play Thanks.
GlynBryan it works on youtube for me, but I know embedded on webpages it wont load and I do not know why.
Thanks sir 👍 👍👍
Please halp me sir
A gearbox manual book online marke address ?
Hi! Did you use the rubber grommets on the bearing retainer bolts?
memory is slipping, if the do not call for that in the parts list I would highly suggest a thread sealent on the threads and a light coat of non hardening sealer (or some gasket maker) on the base of the bolt head.
since these threaded holes access the inside of the transmission you want to keep oil from seeping out.
hi my shift rails are stuck? one of them! any ideal how to take it out? tried wd-40? no luck?
+Ricardo Rodriguez anymore detail you can provide? Follow all the steps? What did you do so far? Do they move at all.
Q bien esta ese video se entiende todo .hola amigo me podría decir si todavía hay repuestos para la caja de trasmicion de un jeep willlys m 38 1 y q me cuenta los repuestos espero su respuesta si
Most people here run from differential work.
+Ken MacMillan Yes you are correct! maybe one day I will make a video of that.
if one can do a transmission or transfer rebuild then one should be able to do a differential, most people just need to understand the proper order in which one would rebuild a diff and it helps to invest or make setup tools. the actual process of rebuilding is straight forward. a company that marks for pinion depth and the use of a pinion depth gauge makes things super easy, reading patterns I think scares allot of people away.
HI BUDDY, can i ask you your help to find parts for my WARNER T85N wit overdrive R11-1W ? they told me is a rare trans.
help me please,i heve to rebuild it...almost all the gears are broken and shafts in bad conditions..
I have the T96 with OD and a complete series about them. The R11 OD is indeed quite rare, but the only difference between the R11 and my R10 is the R11 has 4 planet gears instead of 3. And yes, I do believe the T85 is kinda rare, but Iv'e seen some T86s on ebay.
I also believe the T85 and T86 are quite similar to the T96. So you might want to filter through some of my videos (there are alot of them unfortuantely) just in case there is some info that might be of help to you.
As for parts, ebay has lots, and you could also try kaiserwillys.com and hermtheoverdriveguy.com. rockauto also has the needle bearings for under $10. They can also simply be cut from a suitable rod for even cheaper if you really wanted to.
If the gears have some pitting and scratches, thats not going to interfere with driving. But if most of the gears are broken and seriously damaged, then I think it might not be worth it trying to find and replace so many expensive gears. The other option is buying another parts transmission.
Good help on that :)
Cari sperpatnya dm-an bos
Thank you for your video. I have just taken apart my T 90 and I am cleaning it out. Any advice on the best place to get seals? I might also need secondary shaft.
I will also be using this for reference when I take mine apart and know the steps I want to keep this in mind where you are are where you are and if you could send me your email and address and phone number that would be great cuz I'm good at everything and operating but I'm not much of a mechanic but I'm pretty good at maintenance
Great video
