Engine Make:
Allis-Chalmers
Engine Model:
Likely a 6-cylinder diesel engine, common for this tractor class (specific model designation required from tractor data).
Displacement:
Typically in the range of 6.6L (401 cu in) to 7.8L (474 cu in) for tractors of this era and size, but specific to 7000 model.
Horsepower:
Estimated 100-130 PTO horsepower range, depending on specific configuration and engine variant.
Torque:
Significant torque output suitable for heavy draft work, specific figures vary.
Injection Type:
Direct injection, likely with rotary or inline injection pumps.
Air Induction:
Naturally aspirated or turbocharged, depending on the specific 7000 variant.
Type:
Powershift transmission (e.g., 16-speed or 20-speed) was a common feature on higher-horsepower tractors like the 7000 series.
Type:
Potentially a manual synchromesh transmission as an alternative on some configurations.
Gear Selection:
Multiple forward and reverse gears, often with a range selector for different operating conditions.
Fluid Type:
Specific hydraulic/transmission fluid (e.g., Hy-Tran or equivalent) required, detailed in manual.
Wheelbase:
Varies by configuration, but typically around 90-100 inches for this class.
Overall Length:
Typically around 160-180 inches without implements.
Overall Width:
Varies based on tire size and axle configuration.
Operating Weight:
Estimated 10,000 - 12,000 lbs (4500 - 5500 kg) without ballast or implements.
Max Ballast Capacity:
Significant capacity for front and rear ballast, detailed in manual.
Safety Features Coverage:
Manual covers safe operating procedures, maintenance of safety-critical components (brakes, steering).
Brake System:
Hydraulically activated, wet disc brakes common for improved stopping power and longevity.
Operator Station:
Provisions for Roll-Over Protective Structures (ROPS) and seat belts were becoming standard.
Features:
Basic operator controls, dashboard indicators. Advanced infotainment systems were not a feature of tractors from this era.
Features:
Focus on mechanical and hydraulic controls. Features like auto-steer or GPS were not integrated.
Features:
No electronic connectivity features. Manual focuses on mechanical and hydraulic system diagnostics.
Engine Oil Change:
Typically 250 hours or annually, but specific interval requires consulting the manual.
Transmission Fluid Change:
Commonly 1000-1200 hours, but critical to follow manual recommendations.
Hydraulic Fluid Change:
Similar to transmission fluid intervals, often 1000-1200 hours.
Engine Oil:
API CD or CE rated diesel engine oil, viscosity grade (e.g., 15W-40) specified in manual.
Transmission Hydraulic Fluid:
Allis-Chalmers Hy-Tran (or equivalent specification like TDH/THF) is critical for powershift transmissions and hydraulics.
Coolant:
Ethylene glycol based antifreeze, typically a 50/50 mix with distilled water, for freeze and corrosion protection.
Common Wear Points:
Hydraulic pump wear, powershift clutch pack wear, diesel injection system maintenance.
Electrical Issues:
Corrosion on connectors, starter issues, and alternator problems can occur with age.
Heritage:
Allis-Chalmers was a prominent American manufacturer of agricultural and industrial equipment, known for innovation and durability.
Model Series:
The 7000 series represented Allis-Chalmers' higher-horsepower tractor offerings, competing in the utility and row-crop markets.
Production Period:
The 7000 series was produced in the late 1970s and early 1980s.
