Type:
Diesel (Likely based on Cummins or Fiat-Agri engines of the era; specific engine families vary by model and region. Common engines would be turbocharged, inline 6-cylinder diesel engines).
Displacement:
Likely variants of 8.3L Cummins engines for higher horsepower models (e.g., 6CTA8.3), but other engine options might exist. Manual will specify exact displacement for each model.
Typical Horsepower Range:
8670 (approx. 140-160 HP), 8770 (approx. 160-180 HP), 8870 (approx. 180-200 HP), 8970 (approx. 200-220 HP). Exact figures depend on engine variant and PTO horsepower rating.
Typical Torque Range:
Highly dependent on specific engine displacement (e.g., 8.3L Cummins).
Type:
High-pressure common rail (HPCR) or mechanical injection systems, depending on engine model. The manual would detail specifics of fuel pumps, injectors, filters, and high-pressure lines.
Wheelbase:
Varies by model, typically in the range of 105-115 inches (approx. 2667-2921 mm) for MFWD models.
Overall Length:
Varies by model and configuration, usually in the range of 180-200 inches (approx. 4572-5080 mm).
Tire Size Front:
Commonly 14.9R28 for MFWD, but manual will confirm specific options.
Tire Size Rear:
Commonly 18.4R38, 20.8R38, or larger depending on configuration. Manual will confirm specific options.
Operating Weight:
Typically between 16,000 - 20,000 lbs (approx. 7,250 - 9,070 kg), depending on configuration (2WD/MFWD, cab, ballast).
Gvw Rating:
Can be significantly higher with ballast and heavy implements. Manual will provide Gross Vehicle Weight ratings.
