Horsepower:
Approx. 34-38 PTO HP (Gasoline), Approx. 30-33 Drawbar HP (Diesel) - Varies by specific engine option and configuration.
Torque:
Specific torque figures would depend on the engine variant; consult manual for precise data.
Carburetor:
Typically Zenith or Marvel-Schebler models for gasoline engines.
Fuel Type:
Gasoline or Diesel
Oil Type:
Refer to manual for specific API service classification and viscosity grades (e.g., SAE 30, 10W-30).
Coolant:
Ethylene glycol-based antifreeze solution. Refer to manual for specific mixture ratios.
Engine Oil Change:
Typically every 50-100 operating hours, or annually, whichever comes first. Refer to manual for precise interval and oil type.
Air Filter Cleaning:
Dependent on operating conditions, often recommended every 50-100 hours. Consult manual for specific cleaning/replacement procedures.
Transmission Fluid Change:
Refer to manual, typically every 500-1000 operating hours. Use specified tractor hydraulic fluid (e.g., Hy-Gard equivalent).
Engine Oil:
API Service CD or CE, SAE 30 or 10W-30 (verify with manual based on ambient temperature).
Hydraulic Fluid:
Allis-Chalmers THF (Tractor Hydraulic Fluid) or equivalent ISO VG 32/46 universal tractor transmission oil (UTTO).
Coolant:
50/50 mix of ethylene glycol antifreeze and distilled water.
Hydraulic System:
Leaking hydraulic pumps, cylinders, and hoses; worn control valves. Issues with PTO engagement.
Engine:
Carburetor issues (gumming, leaks), ignition system problems (spark plugs, points), cooling system leaks (radiator, hoses).
Transmission:
Worn synchronizers, difficulty shifting gears, clutch wear. Rear axle seal leaks.
Electrical System:
Corroded wiring, faulty switches, weak starter/generator.
Brand Reputation:
Allis-Chalmers was a well-respected American manufacturer known for its robust and innovative agricultural machinery.
Series Progression:
The D10 Series III is an evolution of earlier D10 models, representing refinements in engine, transmission, and hydraulic systems. It often succeeded or paralleled models like the D12 and D14 in the Allis-Chalmers lineup.
Production Years:
The D10 series was produced through the 1960s, with the Series III likely in the mid-to-late 1960s (e.g., 1964-1968, precise dates require further confirmation).
