Engine Make Model:
Typically powered by a Yanmar diesel engine (specific model depends on year and configuration, e.g., 3TNV84 or similar).
Displacement:
Commonly in the range of 1.6 to 2.2 liters (e.g., 2197 cc for a 3TNV84).
Horsepower:
Typically around 20-30 HP (e.g., 25 HP at 2800 RPM for a 3TNV84-NVA).
Torque:
Specific torque figures vary by engine model and tuning.
Injection Type:
Direct Injection (common for Yanmar engines of this era).
Engine Oil Change:
Typically every 250 or 500 operating hours, depending on operating conditions and oil type.
Hydraulic Fluid Change:
Typically every 1000 or 2000 operating hours, often with filter changes at more frequent intervals.
Air Filter Replacement:
As needed, based on air cleaner restriction indicator or regular inspection (e.g., every 250 hours).
Engine Oil:
API CI-4 or CH-4, SAE 10W-30 or 15W-40 diesel engine oil (check manual for specific grade).
Hydraulic Fluid:
ISO VG 46 or equivalent hydraulic/transmission fluid.
Coolant:
Ethylene glycol-based coolant with a 50/50 mix of antifreeze and distilled water.
Common Problems:
Wear on track components (rollers, idlers, sprockets), potential for hydraulic hose leaks under high stress, starter/alternator issues, and general engine maintenance requirements (as with any diesel).
Preventative Maintenance:
Regular greasing of pivot points, track tension adjustment, and diligent fluid level checks are crucial for longevity.
