ah, that'll buff right out.....
What I tought was going to be a "refreshing" is turning into an expensive transmission rebuild. Looks like I need a new cluster gear, first gear and reverse idler gear. :-(
Anyone know what was the original color of the trans and transfer case was from factory ? or was it bare cast iron?
Looking good. I've used POR15 and had great results. How did your redneck rotisserie workout for working with the frame? I'm getting ready to cut the floors out of my tub and really liked the simplicity of your idea.
I've seen then in black sometimes, usually bare cast iron.
Maybe the rebuilt ones were painted.
The rotisserie worked great, not sure how it would work with the weight of a tub though. I use por-15 on most of the metal parts. I was curious on what color the trans and tc came from factory so I can paint them the same. Maybe I'm watching too many Graveyard Carz shows
That's good to hear about the rotisserie. I'm going to give it a try for my tub. I look at a thread that Pielut posted about a home made rotisserie which was simple and inexpensive but I don't know what I would do with it after the tub floors were done.
I thought that all of the T90's and D18 came stock with a light coat of rust with ample amounts of grease caked onto them. I looked at the pic's of various trans and t/c's that I've had over the years and none of them seem to have paint on them. I honestly don't know if they were painted or not from the factory.
Nothing like having your Jeep tub on a rotisserie when your working all around it...................
So I decided to get the t-86 gears I need for the rebuild. I figured I can do it for under $ 400.00 which I would have paid at least that for the conversion. I found NOS front and rear bearings, a reverse idler gear kit and an extinct NOS first/reverse sliding gear.
I went and blasted and painted the transmission housing today.
On a good note, I opened the transfer case today and all the gears look like new. I also found the original color under a layer of thick grease ....black...
While waiting for transmission parts to arrive I disassembled the Dana 18 transfer case today
The E brake drum was a pain to remove ! I didnt have the proper puller. After an hour of frustration i went and borrowed one and had it off in 2 minutes.
I have to learn to degrease these things before I work on them :-/
The end result. everything looked pretty good so I just ordered the overhaul kit.
Soaked some parts in Simple Green degreaser overnight
Kind of weird ! the Simple Green turned some of the parts black, don't know what that's about
Parts are coming this week, sandblasting and painting the case this weekend.
1. inspiring work!
2. Did you pull that Ross steering off there whole? I had a helluva time last night getting the wheel off, and I'm thinking that the box itself isn't going to come off the frame so easy. As yours is just sitting there whole as day! Haha
3. Are you painting those parts with POR15 as well? I know you did the Ross gear box but, did you/are you doing the rest as well?
Yes, I took off the ross box the steering column and the wheel off as one unit. I was replacing the steering wheel anyway because it was damaged so I just used a hammer, otherwise I would have used a puller. Everything that gets painted on the frame gets 2 coats of Por-15 black then when it gets tacky or a bit dryer ( as per directions ) I paint with the finished color. Mostly Por 15's Chassis coat satin black. I used this in two previous restorations and IF DONE CORRECTLY it is bullet proof. But I sandblast everything before painting. I got a cheap bench top blaster from harbour freight.
Great! Thanks for the input! I look forward to watching your progress!
Just picked up this 55 without a motor as a parts Jeep for my project. Going to keep and try to rescue the tub. everything else I am going to sell. I will post parts in the classified section when I figure out what everything is worth and finish taking it apart.
Tomorrows project, rebuilding the T-86
Where'd you get the T86 parts?
I got the nos cluster gear and overhaul kit from willys overland. http://www.willysoverland.com/
The nos bearings I found on ebay. the first/reverse slider gear was the hardest. They don't make reproductions of it. After a few weeks of searching one popped up on ebay so I grabbed it. The reverse idler kit I got from a member here
First thing to do is the reverse idler gear. Unlike the T-90 the T-86 uses needle bearings in this gear so I used assembly grease to install these.
Very carefully slid shaft in keeping slot lined up for locking plate, Reverse gear includes washer, needle bearings then another washer.
Another difference between the 90 and 86. The t-90 uses 88 needle bearings and 6 spacer washers in the cluster gear, the 86 only uses 44 bearings and 4 washers
A 3/4" dowel cut to 7 1/6" is used as a dummy shaft to place the bearings. first a spacer washer
The 22 bearings in place
another washer to cover bearings
Then just turn the gear around and do same to other end in the same sequence. Next I placed the gear with the dummy shaft in place as well as the thrust washers in the bottom of the case
I wrapped a wire around gear so I can lift it later
Interesting thing! when I removed the bearing from the front shaft there was no oil collector behind it. A new one came with the kit so I put it on then pressed on the new bearing. After that the snap ring would not fit, so I had to remove the bearing and discard the oil collector for the snap ring to fit. I find it weird since the blow up drawing for the T-86 has it however I know the history of the Jeep and the trans was never apart.
Front shaft installed
I assembled the main shaft with new syncro's and a new first/reverse slider gear
using seal installer to replace seal in front shaft housing
So now at a stand still, waiting for a couple of answers.
1- After installing the spacer washers and needle bearings in the cluster gear, the spacer washers were not flush with the ends of the shaft as I read they should be. When one is flush the other side is recessed 1/8" Is this normal for the T86 ? The new parts match the old ones perfectly.
2- Of course as my luck would have it, the overhaul kit was missing the front countershaft washer on the front ( large side ) of the cluster gear. I have my old one which has some slight damage from what looks like the spacer washer spinning on it. Can or should I reuse this or am I stuck for a week until I can get a new one ?
