Engine Model:
Typically a diesel engine, specific model to be confirmed by VIN or tractor specifications.
Engine Type:
Likely 4-cylinder or 6-cylinder, naturally aspirated diesel.
Horsepower:
Estimated 70-80 PTO horsepower (specific rating varies by configuration and year).
Torque:
To be detailed in manual; typically significant torque for agricultural applications.
Injection System:
Direct Injection (typical for this era diesel).
Transmission Type:
Likely a constant mesh transmission with multiple forward and reverse gears. Synchro-mesh may be present on higher gears.
Optional Transmission:
Possibility of a Power Shift or Hi-Lo range transmission for increased gear selection.
Pto System:
Rear Power Take-Off (PTO) drive system, likely with multiple speeds (e.g., 540/1000 RPM).
Wheelbase:
Specific dimensions vary, but typical for a utility tractor of this class.
Operating Weight:
Approximately 8,000 - 10,000 lbs (3600 - 4500 kg) without ballast.
Drawbar Horsepower:
Typically 85-90% of PTO horsepower.
Rollover Protection:
ROPS (Roll Over Protective Structure) likely available as an option or standard on later models.
Braking System:
Hydraulically actuated, self-energizing disc brakes.
Operator Station Safety:
Seat belts, safety guards on PTO shaft, warning lights.
Engine Oil Change:
Typically 250-500 hours, depending on operating conditions. Specific interval to be confirmed in manual.
Transmission Fluid Change:
Typically every 1000-1500 hours. Specific interval to be confirmed in manual.
Hydraulic Fluid Change:
Typically every 500-1000 hours. Specific interval to be confirmed in manual.
Engine Oil:
API CD or CE rated, SAE 15W-40 diesel engine oil recommended. Specific viscosity may vary with ambient temperature. Manual will specify.
Transmission Hydraulic Fluid:
Universal Tractor Transmission Fluid (UTTF) or equivalent. Manual will specify exact type and viscosity.
Coolant:
Ethylene glycol based permanent antifreeze with corrosion inhibitors. 50/50 mix with distilled water recommended. Manual will specify type and capacity.
Common Wear Points:
Clutch wear, hydraulic pump efficiency degradation, PTO clutch wear, front axle pivot wear.
Electrical Issues:
Wiring harness degradation, starter motor issues, alternator/charging system problems common in older equipment.
Brand History:
Allis-Chalmers was a significant American manufacturer of agricultural and construction equipment with a long history of innovation.
Series Placement:
The 7000 series was a modern line of tractors introduced in the late 1970s, representing Allis-Chalmers' efforts to compete in the evolving agricultural market.
Production Period:
The Model 7040 was produced in the late 1970s and early 1980s.
