Make And Model:
Allis-Chalmers (specific engine model not provided in product info, but common engines for this era include Perkins or Allis-Chalmers own diesel engines, e.g., AD3.152, 201 Series)
Engine Type:
Likely a 3 or 4-cylinder diesel engine
Bore And Stroke:
Specifics vary by engine variant, but manual would detail these for rebuilds.
Compression Ratio:
Specified in the manual for engine diagnosis and rebuilding.
Horsepower Range:
Typically in the 40-60 PTO horsepower range for this class of tractor
Carburetion Injection:
Likely governed by a diesel injection pump (e.g., Bosch, CAV) and potentially a distributor type injection system for earlier models.
Wheelbase:
Variable based on configuration, but typical for utility tractors of this size.
Operating Weight:
Typically around 4,000 - 5,000 lbs (1814 - 2268 kg), can be ballasted.
Drawbar Horsepower:
Key specification for performance, typically in the 35-50 HP range.
Safety Features Design:
Rollover protective structure (ROPS) might be optional or aftermarket, seatbelts, guards on PTO and moving parts.
Braking System:
Independent rear wheel brakes, potentially with a master brake system for parking.
Operator Station:
Basic operator station with controls, seat, and foot platform.
Engine Oil Change:
Typically every 100-200 hours of operation, depending on operating conditions.
Transmission Oil Change:
Recommended every 500-1000 hours, with filter changes.
Engine Oil:
Viscosity typically SAE 30 or 15W-40 (API CD or higher for diesel engines of that era).
Hydraulic Fluid:
Specific Allis-Chalmers fluid or equivalent universal tractor transmission fluid (UTTF).
Coolant:
Ethylene glycol based antifreeze mixed with distilled water.
Common Wear Items:
Clutch wear, hydraulic pump performance degradation, injector pump timing, PTO clutch wear, starter/alternator issues.
Electrical System Reliability:
Wiring insulation can degrade over time, leading to short circuits or intermittent faults.
Engine Overheating:
Can occur due to clogged radiators, faulty thermostats, or worn water pumps.
