Troubleshooting & Maintenance Tip: The Hino J05E Engine

Common Fault: Komatsu PC200-8 (Engine 6D107) Oil Pressure Too Low

Fault Analysis: Low oil pressure in the Komatsu PC200-8 6D107 engine is often caused by a worn-out Oil Pump Assembly, excessive clearance in the Engine Bearings (Crankshaft and Connecting Rod Bearings), or a clogged oil filter. If the pressure drops suddenly after maintenance, check for improperly seated oil filter housing gaskets.

Treatment Solution: Replace the worn Engine Bearings (using high-quality replacements) and the Oil Pump. Always use the manufacturer-specified grade of engine oil and ensure all oil passages are clear of debris during the repair process.

General Engine Maintenance Plan:

  • Daily Check: Monitor engine oil level, coolant level, and look for visible leaks around the Gasket Kit areas.

  • 500-Hour Interval: Replace engine oil and filters. Inspect the Radiator and cooling lines for corrosion or leaks.

  • 2000-Hour Interval (Overhaul): Inspect and replace internal components as necessary, such as the Piston Ring set, Liner Kit, and major Bearing components, using a full Gasket Kit.
