Allis Chalmers Model U

This is the story of my 1931 Allis-Chalmers Model ‘U’,
and a 1940 Massey-Harris Super ‘101’.

The Allis-Chalmers Model U was purchased locally from a retired
roping champion, Bud Hampton, who used it at the edge of town. It
sat outside after he quit using it but the motor was still free. I
dropped the pan and cleaned it up inside, then paid to have a valve
job done. An interior heat tube in the manifold was rusted out,
causing loss of vacuum and misfiring. I replaced the tube, checked
the compression and installed a seal in the water pump. Then I
proceeded to sand and prime it. I painted it Allis-Chalmers orange
and put on decals ordered from Indiana. It runs good, and is a fine
solid tractor. Am looking forward to showing it this summer.

I bought the Massey-Harris Super ‘101’ from an
individual who purchased it from the previous owner in a
neighboring town. He said it knocked and smoked and he wanted to
sell it. I found later that it had a broken piston, stuck valves,
and a shelled out clutch disc. I had a valve job done, replaced the
piston, new rings and inserts, and new clutch and throw-out
bearing. I sanded and primed the metal and it is painted
Massey-Harris red, with decals ordered from Indiana. I have shown
it for two years and it’s a good puller in the antique tractor
pulls. The factory engine in this model is the Chrysler Industrial
flat head six. I am currently working on a 1938 Allis-Chalmers
model ‘B’ with serial #558.
