Technical Glossary for Heavy-Duty & Automotive Parts

To assist our clients in identifying the right parts, here are 10 key component definitions commonly found in engineering machinery, heavy trucks, agricultural equipment, and automotive applications:

• Hydraulic Pump: Installed in the hydraulic system to convert mechanical power into hydraulic energy. (Example: John Deere 8400R Hydraulic Pump)

• Torque Converter: Located between the engine and transmission, allowing the engine to spin independently of the transmission. (Example: Komatsu WA380-6 Torque Converter)

• Injector Nozzle: Located in the cylinder head, spraying fuel into the combustion chamber. (Example: Cummins ISX15 Injector Nozzle)

• Kingpin Kit: Connects the steering knuckle to the axle beam in heavy trucks. (Example: Freightliner Cascadia Kingpin Kit)

• Differential Carrier: Inside the differential assembly, distributing torque to the axles. (Example: Volvo VNL Differential Carrier)

• PTO Shaft (Power Take-Off): Transmits mechanical power from a tractor to an implement. (Example: Case IH Magnum 340 PTO Shaft)

• EGR Valve (Exhaust Gas Recirculation): Controls the flow of exhaust gas back into the intake manifold. (Example: Ford F-150 5.0L EGR Valve)

• Track Adjuster Assembly: On the track frame of excavators, maintaining correct track tension. (Example: Hitachi ZX490LCH-6 Track Adjuster Assembly)

• Brake Caliper: Part of the braking system that squeezes the brake pads against the rotor. (Example: Mercedes-Benz Actros Brake Caliper)

• Oil Cooler: Usually near the engine block or radiator, cooling the engine oil. (Example: CAT 320D Oil Cooler)
