Komatsu WA320-3H ACTIVE(S/N WA320H20561-UP)

Utilize KOWA (Komatsu Oil Wear Analysis) at every major interval to monitor wear metals like iron and copper, as well as contaminants such as silicon. Regularly check hydraulic fluid via the sight glass and perform hydraulic oil sampling to detect particle counts or oxidation. Monitoring DEF levels and engine oil condition prevents long-term damage to the SAA6D114 engine components and ensures the emissions system remains functional.

Watch for hydraulic leaks at hoses, seals, or pins, which can cause slow boom response. Inspect the 4-speed transmission for smooth shifting; worn components may require filter replacement or oil changes. Check brake system functionality, specifically the hydraulically-actuated wet disc brakes, to ensure effective stopping power. If steering becomes sluggish, inspect articulation pins and bushings for excessive play that requires lubrication or replacement.

Plan for major component evaluations during 2,000-hour intervals. Key rebuild focus areas include the turbocharger inspection, transmission/torque converter oil service, and hydraulic pump evaluation. Monitor structural integrity of the boom and bucket linkages for cracks. For high-hour machines, prepare for potential hydraulic system flushes and replacement of worn heavy-duty pins and bushings to restore factory-spec movement and breakout force.

In dusty environments, frequently check the air filter restriction indicator and clean radiator fins to prevent overheating. During cold operations, ensure engine oil viscosity is appropriate for ambient temperatures; use single-grade oils like SAE 10W-30 or 15W-40 if necessary. In high-moisture areas, prioritize draining the fuel/water separator daily to prevent fuel system contamination and check all grease points to protect against corrosion.
