I have what I think is an Allis Chalmers model B from the 1946-49 era but cannot positively identify it. The only numbers I can find are cast into the block and the transmission housing. The number on the block (A297627) is located on the right side just below the spark plugs and above what appears to be a freeze plug. The number on the transmission (E111946) is located just forward of the shift lever and has the word "TRACTORMO" just below it.

Is there another location I should be looking for model and serial number?

I bought the tractor last summer and have used it for small tasks but it had limited power and had a hard time pulling a three section harrow so I changed plugs and wires today. Now it pulls the harrow great. Only one small problem now. With the extra power, the hub broke loose from the rim. The rim was rusted severely and the hub clamps literally went through the rims!

Now I need to locate another rim to fit the hub and I am not sure what to look for. It has 10-24 tires but I am uncertain regarding what to ask for when shopping for a new rim. Can anyone provide some advise?

Greatly appreciated,

Len Parsons

Without looking at your tractor, I believe you mistook the B for a E in the serial number. Also, it would say TRACTOR NO instead of TRACTOR MO. According to my books, you have a 1950 model. Most rims are available at most tractor supply houses. I would suggest you get the rims with loops and do away with the eccentric type wedges that should be on the tractor now.
