I would like to start a new restoration thread. in 2010 I purchased a collection of parts from a fellow enthusiast. He is a master old iron sleuth and had collected several parts with the idea of creating a Twin City 40-65 tractor.

As you can learn in Tony Thompson's excellent Twin City site, the 40's were a fairly small production, giving way quickly to the newer, smaller tractors. Given this there were several production changes along the production, resulting in essentially no two remaining tractors being the same. I would consider the production to be essentially broken down to prototype, early, mid, and late models. From the prototype to production there were several changes, including steering, clutching and several other smaller changes. The early tractors had round spoke wheels front and back with a short canopy. The mid production models had round front spokes, and flat rear spokes and a short canopy. The later models had flat spokes front and rear, along with a different canopy, and several other smaller changes.

There are a hand full of the later models in different variations still in existence. As we saw in Antique Power Magazine recently, one prototype exists. No early models have been found complete to date.

These parts are for an early tractor.

We have been working on these parts as time allows since '10. While I don't have as many pictures as I should, I have quite a few. With that I thought I would try to document some of our progress.

Having an entirely different career, I can say with great emphasis: if you find a master machinist/all around mechanical expert who is willing to take you under his wing, you should jump at the chance!

These pictures are of some of the parts as originally collected from wreck sites across the US and Canada.

A few more pictures from the original parts group.

Pic 1: We knew the wheels would be a big part of the restoration.

Pic 2: What was left of the structure that connects the bull gears to the rear wheels.

Pic 3: We were hoping we would not need to use this wheel as you could say it's a little out of round. I the background is the flywheel we used. It is for an early expanding shoe clutch used on the early tractors and replaced by a band clutch system fairly early in production.

Very impressive... Is that a set of fenders for the 40 in the background of picture one?

Mike...Not a lot of encouragement in those piles! A very daunting task to have contemplated and I commend you for undertaking it. A project of this magnitude would far surpass my ability to ever complete it.
I went through a fair amount of Twin City literature last winter researching the early 20-35's. Because the 40 was sold during the same period of time I reviewed some information on them as well. After looking over your parts pile pictures I made an educated guess as to what this tractor originally looked like. Photo is from the Twin City Tractor photo archive by P.A. Letourneau.

Didn't Bill Vouk have a TC 40 at that threshing show that used to be held at St. Joseph MN? I think I remember seeing one there in the late 80's.

Jeff...yes those are 40 fenders in the background. Good eye.

Mark...thanks for posting that picture. That's the one. We are trying to get as close to it as we can.

I've heard of restorations being done from an oil stain, but that's about as close as you can come in real life... good luck, quite a project...
I've always liked the looks of those TC tractors.

What parts do you have for the engine?
Tim, I may be mistaken but I believe there is a flywheel, crankcase and a few cylinders pictured in the background of Picture #3/Post #2.

I think you have one heck of a start Mike!

That's a heck of a project, but after seeing what Wendall and Kory and a couple others have done in recent years I'd say it is doable.

Looking forward to progress updates and LOTS of pictures.

:salute:

Hello Mike ,
Looks like a good start, what do you have for the motor ?
Looks to me like they weren't scrapped , but robbed for nuts n bolts and steel to use around the farm , i always say it pays to go back and have another look as it's easy to miss smaller bits ,
Do you have more pics of as found ?
Look forward to seeing progress ,
That out of round wheel rim will come back quite nicely when you tighten all those spokes , might need a little push with a tractor first though,
Can you tell me what the frame rails marked "A" in the pic ?
could they be 25 hp Fairbanks ?
Also is that the diff gear above the rails marked "A" ?
Regards ,
SL .

Stuart...I am afraid I don't know on the spare frame parts or the gear in the background. They didn't come with us.

Pic 1...another view of a fender.

Pic 2...loading the frames. One good one and one spare.

Pic 3...loading the engine. This is a power unit engine as tractor engines are unavailable.

Pic 4...partially loaded for the trip back to Michigan

OTTO-Sawyer...it is an honor to even be mentioned in the same thread as Kory and Wendell.

We would not have been able to even think about this project without being in touch with "the network" that deals with these early large projects. Without help from sources throughout the US we would be out of luck. I'm not sure how many different states will be represented by parts of this tractor, but it will be a big number.

Working locally with guys who know this stuff in and out and can give guidance is invaluable.

I believe the show was at St. Stephen, MN not St. Joeseph.
I stand corrected. The Vouk Show was in St Stephen. I remember going past the Rice Blacksmith Shop (Rice MN) to get there.


Well Mike...that's an interesting motor. With the overhead valves and pressure fed oiling your 40 is going to be on the cutting edge of technology! ;) Was the bore and stroke of this one a close match to the 7 1/4 x 9 dimensions of the original engine?

Mark...yes, this engine is "modern". It has forced lubrication and an integral water pump. Both features not on early tractor engines. The bore and stroke are the same.

In an even later iteration, this engine was even built with a ring gear and electric start.

So now to start talking restoration. As all who have done any restorations know, you tend to bounce around a bit on various components.

For ease of reading, I'll try to show progress for various systems grouped, rather than necessarily in chronological order.

Pic 1: The hubs as we had received them. They had been found in wreck sites and likely had been in this condition for decades. I would guess they were cut down to provide stock tanks, but who knows? The wheels had 7/8" diameter spokes rolled out to 1" threads in the center. These engage in the hub with a lock nut. As you can see the spokes had all been cut off. However, the nuts and base of the spokes were mostly present. A total of 5 were missing and rusted out. With this we were able to weld the remaining nuts to the remaining stubs. We then used a 1" breaker bar with an 8 foot "cheater bar" on it. I then would hang off of the end of the cheater and bounce up and down. Once they were a little loose we used a large impact wrench to spin them out. Of the 75 studs to be removed in this manner only 5 broke off. Those were drilled out and re-tapped. The 5 rusted out holes were drilled oversize and heli-coiled to standard.

Pic's 2-4...the finished hubs. Long days with sore muscles.

After the holes were finished, the bores had to be opened up to a standard size.

I stand corrected. The Vouk Show was in St Stephen. I remember going past the Rice Blacksmith Shop (Rice MN) to get there.
St. Stephen show was about 60 miles from home. My brother Keven was born in 1964. I believe he can say he was at every show from the time he was born until the last show. The show was always around mom's birthday so we always made a family event out of it. Going to the show and then to St. Cloud for supper. My dad was in St. Cloud Hospital during their last show. We were unsure of whether dad was going to survive or not. My brother Keven had hardly left dad's side during his whole ordeal. I talked him into taking a few hours with me to go to that last show. He really needed it and it was only a few miles away. A year later we took dad to the auction of the Vouk show items. It was held on the same show weekend. We tried hard to buy a 35hp Ingeco gas engine as it was a large local engine. It went to Wisconsin. We did end up buying it later at that sale. It went to Rollag and is on display in the Otto building. Just sharing.:)

It looks like there is still a lot of work on this TC to make it to Rollag this year for Minneapolis Expo.:D;)

J Ware... Jeff has been a wealth of information and help on this project. I've really appreciated his help.
