|---|---|---|---|---|
| Caterpillar | 3114 | 3116 | C4 | C6 |
| Komatsu | 4D95 | 6D102 | 6D114 | 6D170 |
| Isuzu | 4BG1 | 4HK1 | 6BG1 | 6HK1 |

Cylinder Liner: Installed in the Cylinder Block. Example: Caterpillar C13 Cylinder Liner used in Cat 345D Excavators.
Piston: Located inside the Cylinder Liner. Example: Komatsu 6D107 Piston for PC200-8.
Main Pump: Mounted on the Engine Flywheel Housing. Example: Volvo D6E Main Pump for EC210B.
Nozzle: Part of the Fuel Injector in the Cylinder Head. Example: Isuzu 6HK1 Fuel Nozzle for ZX330.
Turbocharger: Attached to the Exhaust Manifold. Example: Cummins QSL9 Turbo for various loaders.
Water Pump: Front of the Engine Block. Example: Yanmar 4TNV98 Water Pump for mini-excavators.
Accelerator Motor: Near the Fuel Injection Pump. Example: Komatsu PC200-7 Stepping Motor.
Main Valve: Located in the Hydraulic Control Center. Example: Caterpillar 320D Control Valve.
Crankshaft: Bottom of the Engine Block. Example: Weichai WD10 Crankshaft for heavy trucks.
Radiator: Front of the Cooling System. Example: Kubota V2403 Radiator for U35 excavators.
Common Fault: Low Hydraulic Pressure / Weak Boom Action on Komatsu PC200-8.
Solution: Check the Hydraulic Main Pump (708-2L-00300). If the pump flow is below specifications, it indicates internal wear. Replacing the pump or the Plunger Kit restores the Hydraulic Heart performance. Regular replacement of hydraulic filters every 500 hours is highly recommended to prevent premature failure.
