Engine Details H3:
Typically powered by a gasoline engine (e.g., Waukesha or Continental inline-4) or a diesel engine in later/specific configurations. Specific engine model to be confirmed via VIN or actual unit.
Engine Details Hd3:
Likely equipped with a diesel engine, common for the 'HD' designation in Allis-Chalmers lineups. Specific engine model (e.g., Allis-Chalmers diesel) needs confirmation.
Horsepower Range:
Typically in the 30-40 HP range, depending on the specific engine and configuration. This manual will list the correct part numbers for components related to the original engine.
Fuel Type:
Gasoline or Diesel, depending on the specific model variant and original engine. The parts catalog will detail components for both.
Transmission Type:
Manual transmission with multiple forward and reverse gears, likely featuring a constant mesh or sliding gear design. Clutch type (e.g., dry single-plate) is also detailed.
Optional Features:
While not a typical option, specific regional variations or aftermarket modifications might exist. The catalog would detail original factory options and part numbers.
Drivetrain Components:
Focus on final drives, bevel gears, and track drive sprockets for robust power transfer to the tracks.
Service Intervals:
This is a parts catalog, not a service manual, so specific intervals are not listed. However, it is critical for ordering replacement parts needed for scheduled maintenance and repairs.
Fluid Specifications:
Specific fluid types (engine oil, hydraulic fluid, transmission fluid, coolant) and capacities are not detailed in this parts catalog. This information would be found in the accompanying Service Manual or Owner's Manual.
Common Wear Items:
Based on typical crawler tractor usage, common wear items include track components (links, rollers, idlers, sprockets), clutch plates, and hydraulic seals. The catalog lists all these parts.
Utility For Maintenance:
Indispensable for identifying correct replacement parts for routine maintenance tasks like filter changes, lubrication point replenishment, and component wear replacement.
