Technical Terms & Part Locations

  • Caterpillar 345B Piston: Located inside the cylinder block; essential for converting fuel energy into mechanical motion.

  • Komatsu PC300 Main Relief Valve: Found in the control valve bank; regulates maximum hydraulic system pressure.

  • Isuzu 4HK1 Fuel Injector: Positioned in the cylinder head; delivers atomized fuel to the combustion chamber.

  • Cummins QSB6.7 Turbocharger: Bolted to the exhaust manifold; increases engine air intake efficiency.

  • Yanmar 4TNV98 Water Pump: Mounted on the front of the engine; circulates coolant to prevent overheating.

  • Kubota V2403 Alternator: Driven by the fan belt; generates electrical power to charge the battery.

  • Weichai WD10 Oil Pump: Located in the oil pan area; ensures lubrication of all moving engine parts.

  • Caterpillar C9 Glow Plug: Threaded into the cylinder head; assists in cold weather engine starting.

  • Komatsu D65 Crankshaft: Situated at the bottom of the engine block; translates piston movement into rotation.

  • Isuzu 6WG1 Fan Blade: Attached to the water pump pulley; draws air through the radiator for cooling.

Maintenance & Troubleshooting Guide

Case Study: Komatsu PC200-8 Engine Overheating

Issue: Temperature gauge rises rapidly during heavy lifting.

Solution: Check the Water Pump and Radiator. In many cases, the Yanmar 4TNV94 or Komatsu 6D107 water pump impeller is worn. Replace with our high-quality OEM standard water pump to restore flow.

Maintenance Tip: Always check Hydraulic Cylinder Seals every 2000 hours. Using 456-0202 and 165-9416 seal kits prevents pressure loss and protects the Caterpillar 323FLN hydraulic system.

Product Features

  1. Use for excavator or construction machinery: Specifically designed for high-stress environments like mining and earthmoving.

  2. OEM Standard Sealing: Utilizes high-grade polymers to maintain stable pressure in 456-0202 seal groups.

  3. Perfect Fitment: Guaranteed to fit Caterpillar 345B and Komatsu PC200 without modifications.

  4. High Pressure Resistance: Optimized for the heavy-duty Boom/Arm/Bucket cycle of the Sany SY215C.

  5. Long Service Life: Reduces downtime by solving common 7861-92-4800 float switch failure issues.
