What to do with this T90?

   I like this thread.

   The little Willys suffer the same demise as many old Tractors sitting outside in the elements year-after-year for how many decades ?
   My father has a Ferguson Tractor TO-20 model, and several years back I asked him if he had ever drained the tranny fluid to look for water. He said NO, it is working so why service it ?   The 3-point lift wouldn't stay up and was not lifting very well either.
   So I pulled the drain plug, and the First-thing to drain out was a gallon or better of water before the hydraulic fluid began running out, and looked very milky. My father is not one to "service" anything on a regular basis.

   These little Willys sit outside for decades, and the rain-water runs down the shifting staff and into the transmission. If the owner has not been doing any deep-water-crossings, why should he drain the transmission fluid. Right !
   Wrong !   Neglect will kill most machinery over time, and many of these little Willys are Neglected for decades. ( I have one in my yard that I tell my guests that the '46 Willys is my "Yard-Art" for visual entertainment ).

   I like the photos of the shifting staff ball and the retainer-pin. My guess is that there are many Loose-Staff-Balls out there.
   I have not yet removed a T-90 shifting staff from the cover, so if you would, please explain what it took to remove the retainer-spring.

   The Willys that I restored way-back in 1985 was also jumping out of 2-nd.
I picked up a new 2-nd gear and syncro's. The back-cut-bevel on the gear teeth get badly-worn and when you let-off the gas, the doggon thing would promptly jump out of second.

   Who is a good supplier of good used parts or New-Old-Stock trans pieces ?

   A few months back, I ordered a T-90 input shaft for my L134 from Debella's upon a lead from one of the other members, and upon opening the package, I realized I forgot to order the input bearing with retainer-ring. oh well.
   
   I just read on the news where Amazon had it Biggest-Monday sales ever. hmm

   I am old-school, and don't purchase from Amazon. and too, the details of stuff on Amazon seems very bleak-to-nil. Amazon is just another middle-man making money from each purchase for the convenience of shopping at home, and quickly. I grew-up where we ordered parts from mail-order Catalogues, which was way-before the Internet Existed.

   thanks for the great photos attached ! They should be most helpful for other member's suffering similar shifting-woes. :)

The tower spring is held in my three tabs cast into the inside of the tower, look close at the photo I posted earlier.  I had to use 2 or 3 strong flat screwdrivers to get behind the spring in several locations and pry it out from under each of the tabs.  I worked my way around, about two times until it popped free.  There may be a better way, but I could find no guidance.  After the spring was out, the cane pulls out from the bottom.

Yep, thats about what I did. But I struggled a bit more than he did. After I do it few times, I expect it will get easier. Now that I have another T90 on the bench, I'll get a chance to hone my skills 

and that's why used t90's can be had cheap, and refurbed units notsomuch 

I took apart the long shaft tranny and sorted through the parts from both to see what is useable, this is what I can use. I've ordered a NOS input shaft and reverse gear bushing from Debella and a master rebuild kit from Novak. I got the case all cleaned up and painted this morning. Now it's just a matter of waiting on parts to arrive.

Yes indeed. While waiting, I decided to look at its brother and started scraping off 70+ years of crud. It's too cold to power wash it, but I can scrape and then wire brush it with kerosene to get the majority of crud off the outside before breaking it down.

One of the mainshafts had buggered up threads on the output end. It's seems someone beat on it with a steel hammer. Besides that, the shaft is very nice, so I wanted to see if I could save it. The damaged threads were outward of the cotter pin hole, so I figured they offered little or no additional strength after the nut is torqued and cotter pin is installed.

I chucked it in the lathe and took a few light cuts, just enough to remove the damaged threads. The shaft is hardened steel, not easy to cut. I would cut a little, try the nut and repeat until the nut would go on. I think the shaft will be useable now.

Rescue machine shop work at its best!    My hat is off to you.
