I have just purchased a Allis Chalmers model C that is a basket-case and I have a few questions. First, were the blocks the same for all of the model C's? Mine has a large patch were it must have thrown a rod some time in the past.
Where is the serial number plate located, or is it a number stamped on a casting somewhere?
This tractor has a hydraulic pump mounted as part of the rear belt pulley / PTO assembly, my guess is that this is not a "live" hydraulics? This tractor also comes with a mower, culivators, and a two-way plow. I see a small hydraulic cylinder mounted on the right side of the tractor where the seat area is and it looks like there is a place for one on the left side as well, Is this for the plow lift and are there two control valves to work the cylinders seperatly?
And last, are the manuals sold on this site from Jen-Sales?
I hope to have this tractor running to cut some hay this summer and it looks like it's going to be a busy spring!
Thanks for any information anyone can send me, Eric Perry.

I just completed a full restoration on my 1947 Model C last fall. If you have questions, I'll be glad to help out any way I can. Just let me know.

I have a C and i put new brakes on it and they don"t seem to work real well. the new ones are hard as to the old ones were a soft Belt like material. Do you know where i could get some of that soft belt like Material for my brakes or do i have another problem. Thanks for you time, Steve.

the brake material is relatively hard, just like a car drum brake. you need to adjust the screws on the rear cam so you have about 1.5 inch of pedal movement. if they still dont work real well, then the drums are probably scored bad, or oily. the brakes were not ment to stop on a dime, just to slow you down. you might want to compare to someone else B,C,CA to see how it works.

Chris has given you most of the info.
--the B and C motors are the same starting after 1940. THe number on the rear corner of the block will tell you if it is an old BE instead of the newer CE motor.
--the CA is a different internal motor, but it is interchangable as a unit, just dont mix internal parts.
--hydraulics ar not live, must have clutch out to turn the transmission top shaft. the pump on the rear puts out 3000 psi, but only about 2 gallons per minute. thats o.k. becuase the hydraulics and trans oil are the same and only holds 2 gallons, so you dont want to pump more than about 2 quarts into the cylinders.
--you can use 1 or 2 cylinders depending on the lift capacity needed and the design of your implement. they work together off the same lift lever. you can get a splitter and use them independant if one is for the mower lift and another is for the disc lift, etc.
--transmission, hydraulics, and pto are all 1 cavity. 3 drains on the bottom (1/2 inch pipe), and 1 fill on the top, 1 inch pipe plug by your left foot. use 20wt trans-hydraulic fluid. WalMart has 2.5 gallon for $10.
--for books, type in binderbooks as an address and go from there. also can get at local farm store.

Hi Eric! Welcome to the C Allis! They are a fine little tractor. The engines are almost the same thru the entire series.They are also mostly interchangable with the engine that is in the B and the CA.There are a few differences in the early and later engines such as no starter so you have to watch! The serial number is stamped next to the gear shifter. The engine number is stamped on the block.
The hydraulics on a C are not live and of limited capacity. A second cylinder can be added for the plow. There is a selector valve that switches cylinders.
Let me know the S/N of yours and I will look up more info for you.
