Binding:
If printed, likely spiral-bound or comb-bound for lay-flat usability in a workshop environment.
Paper Quality:
Durable, possibly glossy or semi-gloss paper to withstand workshop conditions and ensure clarity of illustrations.
Engine Manufacturer:
Likely Perkins, but Allis-Chalmers also used their own engines or licensed designs. Specific engine model required for precise data.
Engine Type:
Diesel, 4-stroke, naturally aspirated or potentially turbocharged for some variants.
Displacement:
Commonly around 200-300 cubic inches (3.3 - 4.9 liters) for tractors of this era and class. Exact displacement for D-19 Diesel needs verification.
Horsepower Rated:
Typically in the range of 50-70 PTO horsepower, depending on the specific engine configuration and tuning.
Torque Rated:
Significant torque output crucial for heavy draft work. Specific figures vary by engine.
Injection System:
Direct injection, typically with a rotary or inline injection pump (e.g., CAV, Bosch).
Fuel Filter Part Number:
Requires specific service manual or parts catalog lookup for accurate part numbers (e.g., WIX, Baldwin).
Overall Length:
Approx. 140-150 inches (355-380 cm), varies with hitch configuration.
Overall Width:
Approx. 70-80 inches (178-203 cm), varies with tire size and tread settings.
Wheelbase:
Approx. 85-90 inches (216-228 cm).
Operating Weight:
Approximately 5,000 - 6,000 lbs (2,270 - 2,720 kg), depending on options and configuration.
Drawbar Horsepower:
Crucial metric for work output, typically lower than PTO HP, needs manual confirmation.
Engine Oil Change:
Typically every 100-200 operating hours or annually, depending on duty cycle and oil type.
Fuel Filter Change:
Recommended every 250-500 operating hours or as needed if fuel quality is suspect.
Air Filter Service:
Service air cleaner element based on operating conditions (e.g., dusty environments require more frequent checks).
Hydraulic Fluid Change:
Annually or every 500-1000 operating hours, depending on usage and contamination levels.
Engine Oil Viscosity:
Typically SAE 30 or 10W-30 for diesel engines of this era, depending on ambient temperatures. Consult manual for precise API classification (e.g., CD).
Hydraulic Fluid Type:
Allis-Chalmers specifies its own fluids (e.g., Hy-Rev), but compatible UTF (Universal Tractor Transmission) fluids are often used. Manual will detail specifications.
Transmission Fluid Type:
Manual transmission fluid (e.g., SAE 90 gear oil). Manual will specify type and viscosity.
Engine Wear:
Cylinder liner, piston, and ring wear leading to oil consumption and blow-by are common in high-hour engines.
Hydraulic Leaks:
Aging seals and hoses can lead to hydraulic system leaks and reduced performance.
Clutch Wear:
The dual-stage clutch can wear over time, affecting PTO engagement or transmission shifting.
Electrical Issues:
Wiring harness degradation, corrosion in connections, and aging starter/generator components can cause electrical problems.
