I remember the Allis Chalmers line of crawler tractors all using GM 2 cycle diesels , The smallest one the HD5 used a 2/71 then the larger models up to the HD15 used 3/71s, 4/71s and 6/71s. The largest model the HD 20 used a GM 6/110 . All these models were of the same engine family except the 6/110 although of 2 cycle design was completely different and had virtually no common parts with the 71 series . When GM bought Euclid , Allis Chalmers went down the street from their tractor plant and bought Buda Diesel. Various models of the Budas were used in their crawler tractor line including their biggest, at that time, the HD-21. Shortly after buying Buda, Allis Chalmers re-engineered the design of the diesel, particularly the cylinder heads and called them the thousand series of diesels with models like 11000, 21000, etc.
