Willys CJ3A Restoration, T-90 Transmission disassembly

Today I am disassembling the T-90 transmission and inspecting the parts to see what I need to rebuild this unit.

Thank you Brian. I couldn't done it without you!! You are a legend among the flat fender crowd.

[@metalshaperJeep]

Glad to help!

[@peteschmidt1103]

I stumbled across your channel a few weeks ago and have watched every video. Very useful tutorials....your shop and your fab skills are great!

[@metalshaperJeep]

Pete, thanks for the comment, and glad you are enjoying the videos. There is a lot going on all the time around the farm here so keep watching and spread the word. Trying to bring things out there to the world and hopefully inspire the next generation to work with their hands.

Great video. On a similar transmission (36 Plymouth 3 speed), and prior to transmission disassembly, I put the transmission in a pressure engine washer, and it comes out clean of oil and grime. Makes disassembly easier and less messy. God bless

I am a 20 year old from south Georgia. I have a CJ-3A i'm restoring and these videos have been really helpful. Thanks for posting them.

[@metalshaperJeep]

Glad to see the next generation of folks working on these old willys vehicles. Keep watching there are many more videos coming.

[@gregwddriver]

I just buttoned up the column shift three speed in my '46. These videos really helped. Thanks.

[@metalshaperJeep]

great, glad the videos helped you out with your rebuild. Thanks for commenting, and supporting my channel.

[@davehollingsworth3007]

Another great video! Thanks!

[@powers2440]

Thanks for the video this will be really useful when I go to rebuild mine this winter

[@metalshaperJeep]

your welcome. keep watching so you can see how it goes back together. Thanks for the comment, it is always helpful to know that people are getting something out of my videos

Is it better add on a OD unit or put od inside?

[@vickieday5269]

Another help! On the output shaft that has the 14 needle bearings going into the main gear...Finally have the sealed bearing, getting ready to press on the shaft with the oil slinger under it; there is a snap ring groove on the shaft in 2 places. One under the oil slinger and one on the outer side of the bearing. Question is, does a snap ring go in before the oil slinger, then the oil slinger and bearing then another snap ring? Seems like the oil slinger has extra movement on the inner diameter. The small parts kit has 2 snap rings same diameter but 2 different thicknesses. Which each fit into the different thickness snap grooves. The skematic doesn't show another snap ring, but still the question before pressing it on. It's a $30 bearing I don't want to ruin. LOL

[@metalshaperJeep]

there is only one snap ring used. Install the oil slinger, bearing, and then one snap ring, and you are all set. The other groove is not for a snap ring, just how the shafts were manufactured. Brian

Hi Brian, That rack is a great idea, I might make one when I rebuild my transmission. This is a timely series for me. I have a transmission, transfer case and front and rear axles to do. Are you rebuilding the engine as well? That tear down bench is also pretty slick! Please keep up the great work on these videos.

[@metalshaperJeep]

George, I am doing a complete restoration so the transmission, t case, front and rear ends, steering gear, and engine are being rebuilt. Keep watching for more tips on rebuilding. Feel free to copy the rack I built, it will be handy for you in keeping track of things. I often get transmissions in a box from people who have tried to rebuild them and then gave up.

[@thedolt9215]

Nice rack! Are you using GL one mineral oil for lube?

[@HardingConstruction]

Any tips for removing the nut in the transfer case that holds the transmission main shaft? I assume you use something to keep the main shaft from spinning. It's around the 3:50 mark on the video, you just have it removed but didn't show how it was done. Thanks in advance. Super helpful video.

[@metalshaperJeep]

That nut usually isn't too much trouble. Take out cotter pin and then put your transmission in first gear, and transfer case in low. Should give you enough drag to remove the nut. I always use an impact gun to take it off but if you don't have one no problem. If it is really stubborn watch my overdrive video and use an old clutch disc in a vise to hold back on the input shaft. Even with a hand ratchet it will allow you to put enough torque on it to remove it.

[@brandonsmedley3819]

@@metalshaperJeep I know it’s only 6yrs later 😂 but I threw it in low and first and it worked with a ratchet! I love your channel and greatly appreciate your knowledge.

[@davidmoore5021]

On the overdrive. Is one gear preferably better than the other 26/29?

[@metalshaperJeep]

no big deal if you have a 26 or 29 tooth gear for the overdrive. The later transfer cases with the 29 tooth do have a larger and better intermediate gear shaft and I always like later transfer cases with the 1.250" shaft for builds that I do for my personal collection.

[@MayorFuglycools]

What direction would I drive out the reverse idle gear ? Mine is toast LOL Mayor Fuglycool

[@metalshaperJeep]

drive the shaft from the back of the case toward the inside. Make sure you make a note of how the reverse idler gear is in there and put the new one back the same way. Brian

[@MayorFuglycools]

Cool thanks, didn't know if it was a tapered shaft like the intermediate shaft on the Dana 18 :) Mayor Fuglycool

Chào bạn . bạn có hộp số nào giá phế liệu không vậy?

[@frankzabski3038]

you mention if any of the gears have rusting or pitting on them you try to replace them with NOS gears which makes sense depending on the level of resto you are doing. If the rusting and slight pitting is just surface and none of the individual gears are broken off or worn down what it the worse thing that can happen? I was on Novak site recently and man those gears are expensive...thats why I'm asking. Thank you in advance.

[@metalshaperJeep]

Light rust or pitting isn't much of a problem, especially if you use the correct lubricants that I offer. Deep rust will tend to wear the tooth over time. It all depends on how much you drive it, rpm, etc...... Best to look at everything and make a decision when everything is apart.

[@davevanatta1965]

what make over drive do you prefer ?

[@metalshaperJeep]

Advance Adapters Saturn Overdrive is the one I like to use.

[@haledmondson2756]

What was the original frame colour when they came out of the war-time plants?...Hal

[@metalshaperJeep]

military vehicles were painted olive drab. Civilian vehicles beginning in 1945 and up were all painted black.

[@haledmondson2756]

Thank you for your reply....Hal

[@intrepid5144]

You needed to leave the "wedging tool" in place as you "tapped" the bearing out. LOL Everytime you split the cases, when you tapped the bearing back into place, the cases moved back too.

[@metalshaperJeep]

Everybody has their own style of doing things and I am just showing my techniques.

[@rintu4244]

Very nice video .i am from india .from where i get 29 tooth sprocket?

[@rintu4244]

Hello metalshaper i am from india and i have need 29 tooth sprocket.help me please for purchase and part number details etc.

[@aderbalmedeirosdasilva6718]

🔝👏👏👏

[@douglasbattjes3991]

So love all your videos,,,question, how long is your dummy shaft U made?

[@metalshaperJeep]

make the shaft the same length as you main cluster gear that it is going to fit into.

[@douglasbattjes3991]

Thanks so much, figured that out after I thought about it. Have a problem with Overdrive in Jeepster, feels like it free wheeling and when I shift into 3rd sometimes, nothing, any ideas?

[@douglasbattjes3991]

Your the best on the Willys info,,,but you already know that I'm sure, Still working on the 53 pickup restoration, but have a quick question. Have a 50 Jeepster, with over drive issue, when I shift into third some or most of the time theirs nothing there, like in neutral , shift back let up on gas and wallah,, its in. but incorrect, feels like something is out of adjustment, need to put on the hoist and like to know where to start to look,,almost like the clutch is slipping. Transfer case went together like a dream,,Thanks... Doug, Will have to order my oil soon, Also just picked up a 48 all original 100 miles away for $1500. another project. Do you use your seal puller on the rear end of T case to pull the seal with out removing everything or the old type, with slide weight Thanks so much for everything ,,,,Douglas

[@douglasbattjes3991]

Forgot to tell you,,,,love the chickens in the background.,,, like to see them//

[@metalshaperJeep]

Do you have the original overdrive in your jeepster? Has it ever been out or rebuilt? electrically shifted unit? Let me know as much as you can and I will try to steer you in the right direction to get it fixed.

[@mumetndase9891]

I can't find text translate or subtitle this no can help us for understanding what are you talking

[@ravenhhca]

So Brian .........a guy can have a a PTO or overdrive, but not both, unless it is off the front of the crank. Such is life.......you can't have everything

[@metalshaperJeep]

If you look over my tow truck CJ6 you will see that I have a twin stick PTO shifter and overdrive coming off the back of the transfer case. You can have both, but twin stick shifters are getting tougher to find. A normal pto shifter, overdrive, and adapter housing are all you need to have it all.
