A couple years ago, we bought an Allis Chalmers HD11 dozer at a government auction - it is a very low hour unit, the undercarriage is at 90%, but the unit had been sitting - we put new batteries in it, changed out all of the fluids, and fired it up - runs very nice, and works well - the only issue we have is that it overheats.  Trying to find a service manual, parts manual, etc, and also determine what year it is.
 
Engine tag reads:
 
Catalog 4354354
Serial 11-17271
11000 engine
 
The only number i can find on the frame of the unit is: 29C14724
 
It's also got a Carco Winch, model F50SG, on it.
 
Can anyone point me in the right direction?
 
Thanks
Dave

14724 would be 1970.  I'd start with new thermostats, and flush the radiator.

Hey, SnoPro. Welcome aboard. We practically neighbors. ND folks on here are kind of scarce. Darrel
