We finished the axle today. Had to drill a pin for the left hand wheel where it is attached to the hub. On the right it floats and is covered by a dog of sorts.

Pic 1...The left hub in place.

Pic 2...The right hub in place. You can see holes in the middle of the hub. It appears these were a crude way to have a locking differential. The left hub doesn't have them. We would surmise a pin of some sort was inserted. You can see where part of the dog is beat up a bit from use. We suspect whatever was inserted into the hole on the hub rubbed this area on the dog.

Mike...Here is an June 1913 ad extolling some of the virtues of the steering on the early 40's. I find the statement "automatic knuckle joints" to be particularly entertaining. When steering early tractors of this size several words do come to mind but not "automatic".

To satisfy my own curiosity I've been searching early ads to see when the transition from the early models happened. This ad marks the latest I can find for the early round spoke full fendered design.

The next ad is August 1913 which shows the expanded Twin City lineup and the transition away from the earlier models. The "60" and the "15" have been added and all models now are outfitted with flat spoke rear wheels. Another easy to note design change was the move from the full width fenders to the those with the tapered fronts. It would appear that there would have been limited production of the early style 40's in 1913 and advertising up to this point was an effort to move old stock. The assembly floor was probably preoccupied with the new model set up in early '13.

The exhaust outlets on the early "60" tractors may have been instrumental in coining the term "6 popper"!

w that summer is over and our pilgrimage to Rollag is behind us, I'll get back to updates.

Next up is the engine. The original tractor engines are either in tractors or are gone. With this, the next best thing is to use a power unit engine. These, while not original, are in a little better supply, and very similar.

Twin City power units came in different configurations. Style A was followed by B, and C with evolution in each. They also came in either rotation. Tractors were counter-clockwise from the front.

My engine is a Type C with a 7 1/4" bore and 9" stroke.

When we got it home we tore it apart as we had no idea it's condition other than that it was loose. In many ways we were pleasantly surprised, as the engine had little evidence of wear.

Pictures of when we tore it down. We removed everything, but left the jugs on the crank case.

The wrist pins were nice and tight without play. The cylinders were simply honed to get any glazing off. They were still nice and round.

So Mike, will you have to make any major modifications to this later model engine to have it work in your tractor application?

It is my understanding that Twin City power units were kept in the Minneapolis Moline product list well into the 1940's. They were no doubt updated and re-engineered some what. A testament to MSM engineering in any case!

Mike...a couple of questions on the engine. What model designation was used for this engine and in what time frame was this one built? Also were the styles A,B, and C all overhead valve design?

Did the pistons have oil control rings or did you make the modification?

Jeff...We have had to make some adjustments, though not as much as you would expect. I'll put some pictures up to show them.

Mark...I have been fortunate enough to track down parts list/instruction books for the A&B and then the C engines. The A appears to be the L head. The B appears to be the first with the overhead valves. They are open. The C has covered overhead valves. The A had a drip oiler, where the B and C had forced lubrication. Mine is a C.

Craig...The pistons had oil control rings in place.

Mike
