Liner Kit
Installed in the **Cylinder Block**. **Komatsu PC300-8 6D114 Excavator Liner Kit** forms the cylinder bore.
Flameout Solenoid
Near the **Fuel Pump/Injection System**. **Cummins 6BT5.9 Engine Flameout Solenoid** cuts off fuel supply.
Pressure Switch
In the **Hydraulic or Lubrication System**. **Caterpillar 320GC C4 Hydraulic Pressure Switch** monitors pressure.
Main Valve
Part of the **Hydraulic Control Valve Assembly**. **Komatsu PC200-8 Control Valve Main Valve** directs fluid flow.
Valve Guide
Pressed into the **Cylinder Head**. **Isuzu 4BG1 Engine Valve Guide** guides valve movement.
Piston Ring
In the **Piston Grooves**. **Yanmar 4TNV94L Piston Ring Set** seals combustion and controls oil.
Nozzle (Injector)
In the **Cylinder Head/Combustion Chamber**. **Weichai WP12 Diesel Engine Nozzle Injector** sprays fuel.
Crankshaft
In the **Cylinder Block (Main Bearings)**. **Kubota V3800 Engine Crankshaft** converts motion to rotation.
Monitor
In the **Operator's Cabin/Dashboard**. **Komatsu PC400-7 Monitor Display** provides machine status.
Accelerator Motor
Near the **Engine Throttle**. **Caterpillar 330D C9 Accelerator Motor** electronically controls engine speed.
For all heavy equipment, specifically the **Caterpillar 320GC (C4 Engine)**, a crucial preventative measure is the **daily fuel system check**. Always drain the **water separator** (located near the fuel tank/filter) before starting operations. Water in the diesel fuel system can rapidly corrode precision components like the **Nozzle** and **Fuel Pump**, leading to costly engine failure. Regular draining prevents this serious issue and prolongs the life of your **Caterpillar C4 Fuel Injector** components.
