Barry,

    I have been disassembling a Muncie SM 465 transmission this last week.  (what a booger).
Anyway after thoroughly cleaning and washing the case, i brought it in next to the fireplace insert for all moisture to dissipate.   Our 3-year old grand daughter was over visiting at the time.

    The next morning,  yesterday, i picked up the trans case to put it on the hand truck, and the grand daughter had filled it with her "tools" !!
     hahahaha    _ _ _ her "tools" are all of her cooking utensils her yaya has given her.

     So,  later in the morning after yaya (my wife) had gone and picked her up, she helped me with a paint brush giving the case an Acetone bath prepping for paint.   
    Guess i'll have to hope she'll be a good Willys apprentice service-girl.    LoL

     When does the SM 420 get the "install" ?

      Question:    pm me the info on the locker you installed if they are for the model 41 and available.

        Len

Hi Len,  Sounds like you've got a great assistant in the making!  Never too early to start and hey, girls like jeeps too!

I am rethinking the SM420 for Grasshopper.  Leaning toward rebuilding the T90A into a T90C and lower T-case gears - Terra lows or jpet's gears.  That would give a nice low crawl but keep everything original.  I'll save the SM420 for my next build.  Funny how one's idea of the "Dream Jeep" keeps changing!  

The part number for the Lock Right I used is 2415-LR.  That is for a Dana 41 or 44 10 spline rear axle.  The 2 things that you have to watch when installing it are that you'll have to grind a little of the end of the shaft to clear the ring gear, and to check the gap between the drivers.  That's an important distance and should be between .145" and .170" with .152" being ideal.  If it is too wide you will have to replace or add thrust washers.  I ordered thrust washers from McMaster Carr.  Metalshaper on U-tube has a good video on installing the locker.  I'll PM some info on purchasing.

It's been a while since I posted anything.  It's been too cold to work in the barn on a dirt floor with no heat.  I've been busy making jeep plans and helping others with their jeep projects.  Back to my own...

I've decided to stick with the T-90A pushing a set of jpet's transfer case gears for Grasshopper.  Jeff has been gracious enough to let me be one of his test subjects so I'm looking for a transfer case to cut into.  This setup was easy to snag - it had been laying in the woods.  I have been having to hold the stick to stay in 2nd so my plan is to rebuild an extra T-90A and do the transfer case mod.  Then I'll put them in at the same time so I don't lose much driving time.

This is what I found under the covers.  I figured there would be water in it.  Don't know if anything will be usable in the transmission.  Has anyone had luck bringing one back to life after looking like this?  I'd love to hear from you.

Some possible good news.  This is exactly the transfer case I need for Jeff's gears.  D-18 with the 1 1/8" shaft.  The intermediate gear looks pretty good.  Even if there is a little damage to the large gear teeth, they are going to get cut off anyway to make the hub for the new large ring gear.  Hopefully there is no damage inside the intermediate gear where the needle bearing ride.  Fingers crossed!

Looks pretty ruff but still some usable parts in it. It will need new shafts, bearings, and gears at the minimum, but stuff like the oil slinger, front bearing retainer, rear bearing adapter plate, spacer, synchronizer hub, sleeve, springs, and dogs are probably usable.

to many jeeps, parts, and accessories to list here, but apparently enough to keep me in trouble with my wife.

I spent an entire day uncovering this metal workbench and preparing it to rebuild the transmission and transfer case on.  The top has not been seen since my son's high school graduation in 2010! I believe there is a law of physics involved that goes something like:  "Any horizontal surface attracts debris to saturation and then continues to add in the direction opposite of gravity".  I got electric heat set up in the garage and installed LED lighting over the bench and under the shelf.  Now I can work on jeep parts in style!  

Tomorrow will be a big day - disassemble the transfer case to see what condition the intermediate gear is in.  Hoping to send it out to Jeff on Monday.

Absolutely true about horizontal surfaces. It's hard to keep any work bench clear for the next job.

Well, yesterday didn't go as well as I had hoped.  I got the transfer case up on the bench and discovered that some of the teeth on the small gear side of the intermediate gear are pitted pretty bad.
 

So it's back out the the parts jeep fleet.  I pulled the shift towers off of 3 more jeeps.  The first 2 were as bad or worse than the last one,  The 3rd one still had the remnants of the shifter boot attached to the cane which must have slowed the water from seeping in.  The gears look pretty good although there is a small amount of pitting on the reverse gear.  I have the greatest hope for this tranny and transfer case.
 

I am going to pull the transmissions and transfer cases out of these 3 jeeps so I have 4 of each on the bench and hope I can scavenge enough good parts for 1 T-90A and 1 D-18 to put Jeffs gears in.  I hate laying on the cold ground so I've come up with an easier way to pull the parts.  I thought about laying the jeeps on their sides like I've seen in military pictures but I don't want to damage any usable body parts, although there's probably not much usable.  I am going to make a safely post out of a spare basement jack post so I'm not just relying on the tractor hydraulics to keep me from getting crushed.

I had a toothbrush in there scrubbing a couple spots and got debis on it.  I should have sprayed it off before I took the picture.  The only pitting I saw so far was on the reverse gear and and looked minor.  I won't really know until I pull it and get it up on the bench.  Fingers crossed!

Yesterday I made a safety post out of some 4x4s that were laying around.  Today I spent the entire day pulling 3 more jeeps out looking for a good transfer case to pull an intermediate gear out of.


Disappointed to find there was water in all of them.  Two of them are really trashed.  I had the highest hopes for this one because the transmission looked pretty good but the t-case is really bad.


This one is my best bet.  I'll pull the transfer case out and get it apart to see what I can salvage.

Hey Barry S.  You wouldn't happen to have a matching pair of narrow track axles out of a Cj 5 by any chance?

Hi Mark,  All my extra axles are D25/27s and D41s out of CJ2As.  I have 1 CJ5 that I tracked down for the rare D44 offset diff flanged rear axle.  I believe it was only used in 70 1/2 thru 71.  After that they went to AMC.  It will be used in my next flatfender project.  A good place to start might be the "Wanted to Buy" section here on the page.  You will probably want to be more specific though because CJ5s have so many different axles over the years.

Ok  Thanks.  I just saw you had a Cj5 siting beside your shop and I was curious about it.  That is actually the same axle that I am looking for too. And yes it only came in a couple of years. 

Thanks again, Mark

Progress report on the last 2 full days of jeep fun.  Having the Jeep that far up in the air made it easy to work underneath.  


Lowering the t-case took everything I had.  Gone are my younger days of lowering a standard transmission down onto my chest and then rolling over with it.  I used to reinstall them the same way.  I sense a transmission jack in my future.




On the bench and disassembly started.  Ran into the first snag right away - couldn't get the nut loose on the front output shafts because everything kept moving around.  Luckily I had a chain wrench with a 24" handle that I could wrap around the base of the hub.  Next time I'll loosen the nuts while it's still in the jeep.





My Harbor Freight puller kit worked fine on the front output hub.  To make it work on the rear output hub I used 3/8 - 24 rod coupling nuts and 1" bolts.  Worked like a charm.



Knocking the intermediate gear shaft out.




One intermediate gear came right out but the other one would not budge.  Had to get a little creative with some rope - that pulled it right out.




Every step I did to one I also did to the other.  When it came time to pull the main shafts the first one slid right out of the high range output gear after removing the snap ring and thrust washer.  When I pulled the snap ring off the second t-case I discovered that the thrust washer was turned and one of the tabs was broken off.  I think the broken tab is wedged under the output gear because it will not slide off the main shaft.  I think the only way to continue disassembling would be to cut the main shaft off inside the case with the "blue wrench".  The parts in that t-case are worse than the other one so I an abandoning that one.



Here is the disassembled t-case I will use for Jeffs gears.  The intermediate and output gears both have a little minor pitting.  The other gears get replaced anyway.  After the parts washer and sandblaster I can make a final evaluation.  I am planning on ordering the Novak 1 1/8" complete rebuild kit.  Is that the best one?




Once I got both D-18 small hole 1 1/8" shaft t-cases up on the bench I started noticing differences.  The one on the left is out of CJ2A  ser#36723.  It had short shift levers, (see photo of them on the bench above), used larger (1 1/4" socket) fine thread castle nuts with cotter pins on the output shafts, and had an extra hole and slot in the casting against the transmission.  The other one came out of a CJ2A with Body tag 194304 but frame tag 04893.  It has much longer shift levers, output shafts with coarse threads and locknuts (1 1/8"socket) (no holes for cotter pins).  There is evidence that both t-cases had been taken apart by PO's so there's no telling what had been swapped around.  Can anyone shed any light?  The one on the right is the one I'll be using. Guess you have to be careful when ordering parts!
