Identification of specific tools required for service and repair procedures.
Depth Of Information:
Detailed, factory-level repair and overhaul procedures, suitable for experienced mechanics and tractor owners undertaking major repairs.
Digital File Format:
If digital, likely PDF with searchable text for ease of use.
Printed Material Quality:
If printed, expect clear diagrams, legible text, and durable paper stock suitable for workshop environments.
Printed Manual Binding:
Likely comb-bound, spiral-bound, or perfect-bound for lay-flat usability.
Printed Manual Paper:
Durable, possibly glossy or semi-gloss paper to protect against workshop grime and oil.
Engine Make Model:
Likely a Continental engine (e.g., Z129, Z134, or similar) or an Allis-Chalmers in-house diesel engine, depending on the specific variant. Precise engine identification would require serial number lookup.
Horsepower Range:
Typically in the 30-40 PTO horsepower range. Exact figures vary based on engine option (gasoline or diesel).
Torque Characteristics:
Designed for good lugging ability at lower RPMs, characteristic of agricultural diesel engines of the era.
Carburetor Or Injection:
Gasoline models would feature a carburetor (e.g., Zenith, Stromberg). Diesel models would utilize a direct injection fuel system with a rotary or inline injection pump (e.g., Bosch, CAV).
Engine Fuel Type:
Gasoline or Diesel, depending on the specific tractor configuration.
Transmission Type:
Likely a constant mesh manual transmission with multiple forward speeds and one reverse (e.g., 6-speed, 8-speed, or 10-speed options).
Optional Transmission Features:
Possibility of a multi-power or shuttle-shift option on some Series II models for enhanced forward/reverse functionality.
Power Take Off Pto:
Standard rear PTO (540 RPM) and potentially a live PTO or independent PTO system.
Safety Standards:
No formal crash ratings for tractors; safety pertains to operational stability, braking effectiveness, and guarding of moving parts as per contemporary standards.
Braking System:
Typically mechanical drum brakes on the rear axle, or possibly inboard wet disc brakes on later or more advanced versions. Handbrake for parking.
Operator Protection:
Basic operator controls, fenders to prevent thrown debris, rear view mirrors on some configurations. Rollover Protective Structures (ROPS) were not standard but often available as an aftermarket or factory option later in its production life or for Series II models.
Engine Oil Change:
Typically every 50-100 operating hours, depending on operating conditions and oil type used. Refer to manual for exact interval and oil specification.
Air Filter Service:
Regular checks based on operating environment; cleaning or replacement often required every 50-100 hours or as conditions dictate.
Transmission Oil Change:
Annually or every 500-1000 operating hours, with filter replacement.
Engine Oil Specification:
API Service Classification CD or CE for diesel, or similar for gasoline. Viscosity typically SAE 30 or 10W-30/15W-40 depending on ambient temperature. Consult manual for precise API rating and SAE grade.
Hydraulic Fluid Type:
Allis-Chalmers HD "Type 35" hydraulic fluid or equivalent. Often a multi-purpose tractor hydraulic fluid meeting specific viscosity and additive requirements.
Coolant Type:
Ethylene glycol-based antifreeze mixed with distilled water (50/50 ratio) for freeze protection and corrosion inhibition.
Common Wear Points:
Hydraulic pump wear, PTO clutch engagement issues, steering linkage wear, carburetor or injection pump tuning, potential for cooling system leaks.
Electrical System Quirks:
Wiring degradation over time, starter solenoid issues, generator output problems.
Allis Chalmers Legacy:
Allis-Chalmers was a major American manufacturer of agricultural and construction machinery, known for innovation and durability.
D Series Development:
The D-15 was part of the successful D-series line, evolving from earlier models with improvements in power, hydraulics, and operator comfort. The Series II designation indicates a significant update or redesign from the original D-15.
Production Period:
The D-15 Series II was produced in the early to mid-1960s, following the original D-15 (circa 1955-1960).
