Engine Family:
Typically powered by John Deere built engines in this era, but Allis-Chalmers also produced their own or sourced from others. Specific engine details for the 8070 require manual lookup.
Gross Horsepower Estimated:
Approximately 135-150 PTO HP (This is an estimation, the manual would provide exact figures)
Displacement Estimated:
Likely in the 400-450 cubic inch range (This is an estimation, the manual would provide exact figures)
Injection Type:
Direct Injection (Typical for this class of tractor)
Transmission Type:
Powershift (e.g., 20-speed or similar)
Optional Transmission:
Likely standard powershift, but manual would confirm any variants.
Gear Selection:
Multiple forward and reverse gears with power shifting capabilities
Transmission Fluid Type:
Specified in manual (e.g., Hy-Trans, UTF, or specific tractor oil)
Engine Oil Change:
Refer to manual (Typically 250-500 hours for tractors of this era)
Hydraulic Fluid Change:
Refer to manual (Typically annually or every 1000-2000 hours)
Air Filter Replacement:
Refer to manual (Based on operating conditions)
Engine Oil Grade:
Refer to manual (Likely 15W-40 or 10W-30 Diesel engine oil meeting API CG-4 or similar)
Hydraulic Fluid Type:
Refer to manual (Could be a specific Allis-Chalmers fluid, UTF, or a premium tractor hydraulic oil)
Coolant Type:
Refer to manual (Likely a conventional green or ethylene glycol-based coolant)
Common Wear Points:
Hydraulic pump wear, transmission clutch packs, electrical wiring corrosion (typical for older heavy equipment)
Troubleshooting Focus:
The manual would detail common symptoms and diagnostic steps for these issues.
