Fuel Injection:
Direct Injection (Mechanical fuel pump, potentially with turbocharging and intercooling).
Overall Length:
Varies, but generally around 5.5-6.5 meters (215-255 inches).
Overall Width:
Varies with tire size, typically 2.5-3 meters (100-120 inches) for road legal configurations.
Height To Cab:
Approximately 3 meters (118 inches) to the top of the cab.
Operating Weight:
Approximately 8,000-10,000 kg (17,600-22,000 lbs) without ballast.
Max Ballasted Weight:
Can be significantly increased with ballast for traction.
Engine Oil Change:
Typically every 250 hours, or annually, depending on operating conditions. Refer to specific engine manual for precise intervals.
Transmission Fluid Change:
Varies significantly; often around 1000-1500 hours. Critical to consult original service literature.
Hydraulic Fluid Change:
Typically every 1000-1200 hours, with filter changes more frequently.
Air Filter Maintenance:
Inspect and clean/replace based on operating conditions and indicator, often at 250-500 hour intervals.
Engine Oil Viscosity:
API CD or CE rated, SAE 15W-40 is common for this era and type of engine. Consult specific Cummins manual.
Transmission Hydraulic Fluid:
Case Hy-Tran Plus or equivalent UTF (Universal Tractor Fluid) meeting Case specifications. Specific fluid type is crucial for powershift transmissions.
Coolant Type:
Ethylene glycol based antifreeze mixture (50/50) for freeze and corrosion protection.
Powershift Wear:
Wear on clutch packs and associated seals within the powershift transmission can lead to shifting issues or loss of power if not maintained. Proper fluid maintenance is key.
Hydraulic System Leaks:
Common with age, leaks can occur at seals, hoses, and cylinders, requiring careful inspection and part replacement.
Articulation Joint Wear:
Wear in the articulation joint kingpins and bushings can lead to sloppy steering and increased tire wear.
Diesel Particulate Buildup:
Older engines without advanced emissions controls can accumulate carbon in intake and exhaust systems, requiring periodic cleaning.
