Turbocharged Diesel Engine (e.g., 6-cylinder)
Engine Displacement:
Typically around 415 cubic inches (6.8 Liters), subject to specific engine configuration within the 7080 series.
Horsepower Rated:
Around 150-170 PTO horsepower (Power Take-Off), with variations based on engine tuning and specific model year.
Torque Peak:
Significant torque output for heavy-duty agricultural applications, details found within the manual.
Injection Type:
Direct Injection, typically with Bosch or similar high-pressure fuel injection pumps.
Transmission Type:
Powershift Transmission (e.g., 20-speed)
Transmission Variants:
While primarily featuring a powershift, some documentation might allude to or cover specific gearbox options or variations if applicable.
Powershift Functionality:
Enables on-the-go gear changes without using the clutch pedal, significantly enhancing operational efficiency.
Gear Selection:
Multiple forward and reverse gear selections to optimize for various field conditions and tasks.
Overall Length:
Varies, but generally a substantial agricultural tractor. Specific dimensions available in the manual.
Overall Width:
Varies based on tire configuration, but designed for stability and clearance. Specific dimensions available in the manual.
Operating Weight:
Significant, typically in the range of 15,000 - 20,000 lbs (6,800 - 9,070 kg) without ballast. Manual will provide precise weights.
Engine Oil Change:
Typically every 250-500 operating hours, depending on operating conditions. Manual will specify exact interval and oil type.
Hydraulic Fluid Change:
Recommended at intervals such as 1000-2000 operating hours. Manual will detail the specific frequency and fluid type.
Engine Oil Viscosity:
Likely SAE 15W-40 or 30W, conforming to API CD or CE service classification. Manual provides precise specifications.
Hydraulic Fluid Type:
Typically a universal tractor transmission fluid (UTTO) or a specialized hydraulic oil. Manual will specify exact Allis-Chalmers approved fluid.
Transmission Fluid Type:
Often shares the same fluid as the hydraulic system. Manual confirms specifications.
Coolant Type:
Ethylene glycol based antifreeze with corrosion inhibitors. Manual will specify mixture ratio and type.
Common Wear Points:
As with any older heavy machinery, potential wear in the powershift clutch packs, hydraulic pump, and front axle components are common areas for inspection and potential repair.
Electrical Connections:
Corrosion or looseness in electrical connections can lead to intermittent issues. Manual's wiring diagrams are crucial for diagnosis.
