Specific model varies by production year and configuration, but commonly sourced from their own engine divisions or reputable manufacturers like Perkins (used in many A-C tractors). Displacement Typical Displacement: Likely in the range of 200-300 cubic inches (3.3 to 4.9 liters) for a tractor of this class and era. Exact displacement requires referencing specific engine codes if available. Fuel System Type: Direct Injection Diesel fuel system with a diesel injection pump and injectors. 🔧 Transmission Standard Type: Often equipped with a manual transmission, potentially with multiple ranges (e.g., 8-speed, 12-speed, or more depending on options) and a high/low range splitter for increased gear selection. Optional Type: Some configurations might have offered a partial power shift or torque converter transmission, though manual was more common for this class. Features Engagement: Clutch pedal operation for gear changes. 📐 Dimensions Exterior Overall Length: Varies significantly with backhoe configuration; typical tractor length without backhoe is around 130-150 inches (330-380 cm). Backhoe adds considerable length when stowed. Weights Operating Weight: Typically ranges from 8,000 to 12,000 lbs (3,600 to 5,400 kg) depending on options and backhoe equipment. 💡 Technology Features Infotainment Features: Basic operator controls; no modern infotainment systems. Driver Assistance Features: No electronic driver assistance systems; operation relies on mechanical controls and operator skill. Connectivity Features: No electronic connectivity features. 🔧 Maintenance Service Intervals Engine Oil Change: Typically every 250-500 operating hours, or annually, depending on operating conditions. Refer to specific engine service manual for exact intervals. Hydraulic Fluid Change: Generally recommended every 1000-2000 operating hours, or as dictated by fluid analysis. Fluid Specifications Engine Oil: API CD or CE rated diesel engine oil, SAE 30 or 15W-40 depending on ambient temperature. Specific viscosity and type as per the original equipment manufacturer (OEM) recommendations for the installed engine. Hydraulic Fluid: Typically a high-quality hydraulic fluid meeting ISO VG 46 (or equivalent) specifications. May also specify UTF (Universal Tractor Transmission Fluid) or similar if the transmission and hydraulics share a common sump. Consult original service documentation. Transmission Fluid: If separate from hydraulics, it would likely be gear oil (e.g., SAE 90) for the gearbox and differential. Specifications would vary. Known Issues Common Wear Points: Wear on backhoe bucket pins and bushings, pivot points for loader arms,...
