Technical Terminology & Installation Guide

Proper knowledge of components ensures longevity. Here are key technical terms for engineering machinery:

• Turbocharger: Installed on the engine exhaust manifold. Example: Cummins QSB6.7 Turbocharger increases power output by forcing extra air into the combustion chamber.

• Main Relief Valve: Located on the main control valve bank. Example: Komatsu PC200-8 Main Valve regulates the maximum hydraulic pressure for all functions.

• Cylinder Liner: Fitted inside the cylinder block. Example: Caterpillar C7 Cylinder Liner provides a smooth surface for piston movement while maintaining compression.

• Fuel Injector: Mounted in the cylinder head. Example: Isuzu 4HK1 Fuel Injector precisely delivers high-pressure diesel into the combustion chamber.

• Glow Plug: Located in the combustion chamber. Example: Kubota V2403 Glow Plug assists in cold starting by heating the cylinder.

• Oil Pump: Installed at the front of the engine. Example: Yanmar 4TNV94 Oil Pump circulates lubricant to all moving engine parts.

• Water Pump: Attached to the engine block. Example: Weichai WD615 Water Pump prevents overheating by circulating coolant through the radiator.

• Floating Switch: Installed inside the fuel or hydraulic tank. Example: Komatsu 7861-92-4800 Float Switch monitors fluid levels to prevent system cavitation.

• Piston Ring Set: Installed on the piston. Example: Mitsubishi 6D16 Piston Ring seals the combustion chamber and controls oil consumption.

• Thrust Washer: Located on the crankshaft main bearing caps. Example: Hino J08E Thrust Washer controls the axial movement (end play) of the crankshaft.
