Driver Assistance Driver Assistance Features: N/A (Basic power steering may be present on some models, but no electronic driver assistance). 🔧 Maintenance Service Intervals Engine Oil Change: Typically every 100-150 operating hours or annually. Air Filter Check: Daily or as needed based on operating conditions. Fuel Filter Replacement: Periodically, as per manual recommendations (e.g., annually or at 250 hours). Hydraulic Fluid Change: Typically every 500-1000 operating hours or annually. Fluid Specifications Engine Oil Type: API Service CD or CE rated, SAE 10W-30 or 15W-40 diesel engine oil recommended. Hydraulic Fluid Type: Allis-Chalmers THF (Tractor Hydraulic Fluid) or equivalent UTF (Universal Tractor Transmission Fluid) meeting specific viscosity and additive requirements. Coolant Type: Ethylene glycol antifreeze solution with corrosion inhibitors, typically a 50/50 mix with water. Transmission Fluid Type: Often shared with hydraulic system; refer to manual for specific type (UTF/THF). Known Issues Common Wear Points: Hydraulic pump wear, clutch wear, PTO spline wear, seal leaks (engine, transmission, hydraulics). Engine Specific: Perkins engines are generally robust but may require attention to injection pump timing or injector wear. Electrical System: Older wiring harnesses can degrade; starter and alternator reliability are typical maintenance points. Operator Interface: Wear in control linkages and levers can develop over time. 📚 Vehicle History Brand Heritage Manufacturer Legacy: Allis-Chalmers was a prominent American manufacturer of agricultural machinery, known for innovation and durable equipment, operating from the late 19th...
