Engine Types:
Available with gasoline (e.g., Continental F-226), diesel (e.g., Allis-Chalmers 250, 262), and LP gas engines.
Horsepower Range:
Typically in the 40-60 PTO horsepower range, depending on engine variant and configuration.
Carburetor Models:
Marvel-Schebler (gasoline/LP) or equivalent Zenith carburetors.
Diesel Injection Pump:
Typically Roosa-Master or Bosch inline injection pumps for diesel variants.
Engine Oil Change:
Typically every 50-75 operating hours or annually. Refer to specific engine type in manual.
Transmission Oil Change:
Initially around 500-1000 operating hours. Check manual for specific intervals and fluid types.
Engine Oil Viscosity:
SAE 10W-30 or 10W-40 for gasoline engines; SAE 30 or 15W-40 for diesel engines. Consult manual for exact API service ratings.
Hydraulic Fluid Type:
Allis-Chalmers specified HD Transmission Oil, but modern equivalents like John Deere Hy-Gard, Case IH TCH Fluid, or universal tractor transmission fluids (UTTO) are often suitable. Check manual for Type 35 or similar designations.
Coolant Type:
Ethylene glycol based antifreeze mixed with distilled water, typically a 50/50 ratio. Refer to manual for specific antifreeze type.
Common Wear Items:

Company Background:
Allis-Chalmers was a prominent American manufacturer of agricultural and construction machinery, known for its distinctive orange color scheme.
D Series Lineage:
The D-17 was a popular model in the Allis-Chalmers D-Series lineup, succeeding earlier models and evolving through several series (I, II, III, IV) with upgrades in engines, hydraulics, and styling.
Production Years:
The D-17 series was produced from approximately 1957 to 1967. The Series IV was a later iteration.
