Approximately 262 cubic inches (4.3 Liters) (Based on typical D-19 engine)
Horsepower Est:
Around 60-70 PTO horsepower (This is an estimate, manual would provide exact figures)
Torque Est:
Significant torque for heavy draft work (Specific figures would be in the manual)
Injection System:
Direct injection, likely with Bosch or similar injection pump (Manual would specify).
Cooling Method:
Liquid-cooled (Radiator, coolant, thermostat).
Oil Type Recommendation:
Diesel engine oil (e.g., API CD or higher, viscosity dependent on temperature – manual specifies).
Transmission Type:
Constant Mesh, Sliding Gear
Gear Configuration:
Multiple forward speeds and reverse (e.g., 6 or 8 forward speeds are common for this era tractor).
Power Take Off Pto:
Independent PTO and/or transmission-driven PTO.
Clutch Type:
Dual-stage dry clutch (typically for PTO engagement and transmission drive).
Transmission Fluid:
Tractor Hydraulic Fluid (THF) or equivalent, potentially a specific Allis-Chalmers fluid (Manual will specify exact type and capacity).
Wheelbase:
Variable depending on configuration, but typically around 85-90 inches.
Overall Length:
Approx. 130-140 inches (without implements).
Operating Weight Est:
Around 5,500 - 6,500 lbs (unballasted).
Drawbar Pull Capacity Est:
Substantial, suitable for a tractor of its class.
Operator Protection:
As originally manufactured, may not include modern ROPS (Roll-Over Protective Structure) or seatbelts unless factory-fitted or an aftermarket addition.
Braking System:
Drum brakes or disc brakes (depending on specific configuration), operated by foot pedals, often with an independent parking brake function.
Operator Station:
Basic controls, dashboard indicators. Manual would detail safe operation and maintenance.
Engine Oil Change:
Typically every 100-200 hours of operation (Manual will provide exact recommendation).
Air Filter Service:
Check and service regularly based on operating conditions (Manual specifies frequency and procedure).
Fuel Filter Replacement:
Periodic replacement, often tied to hours or annual service (Manual will specify).
Transmission Fluid Change:
Typically annually or every 500-1000 hours, depending on workload (Manual specifies).
Engine Oil Viscosity:
e.g., SAE 30 or 15W-40, depending on ambient temperature (Manual is the definitive source).
Coolant Type:
Ethylene glycol based antifreeze/coolant (Manual specifies mix ratio and type).
Hydraulic Fluid Spec:
