Technical Glossary: Key Spare Parts Explained

• Fuel Pump Assembly (Auto Part): Located in the fuel tank, it delivers fuel to the engine. Example: Toyota Camry 2.5L Fuel Pump.

• Hydraulic Cylinder Seal Kit (Construction Machinery): Installed in hydraulic cylinders (boom/arm/bucket) to prevent fluid leakage. Example: Komatsu PC200-8 Boom Cylinder Seal Kit.

• EGR Valve (Heavy Truck Part): Exhaust Gas Recirculation Valve, controls the amount of exhaust gas going back to the engine intake to reduce NOx. Example: Volvo FH16 EGR Valve.

• Clutch Pressure Plate (Agricultural Machinery): Part of the clutch system that pushes the friction disc against the flywheel. Example: John Deere 6155R Clutch Pressure Plate.

• Steering Knuckle (Auto Part): Connects the wheel to the suspension and steering components. Example: Honda CR-V Steering Knuckle.

• Final Drive Gear (Construction Machinery): Located at the track drive, it provides the final reduction and torque to the track. Example: Caterpillar 345D Final Drive Gear (Катерпиллер 345D Бортовой редуктор).

• Turbocharger Cartridge (Heavy Truck Part): The core rotating assembly of the turbocharger, including the compressor and turbine wheels. Example: Mercedes-Benz Actros Turbocharger Cartridge.

• Tie Rod End (Agricultural Machinery): Connects the steering rack/box to the steering knuckle, allowing wheel movement. Example: Massey Ferguson 5713 Tie Rod End.

• Brake Caliper (Auto Part): Part of the braking system that houses the brake pads and pistons. Example: BMW 3 Series Brake Caliper.

• Fan Motor (Construction Machinery): Drives the cooling fan, typically located near the radiator or hydraulic cooler. Example: Hitachi ZAXIS 200-3 Fan Motor (Хитачи ZAXIS 200-3 Вентиляторный двигатель).

Troubleshooting Corner: Common Equipment Issues

Issue: Caterpillar 320D Excavator Fails to Start or Starts Intermittently.
           Possible Cause (Starter Relay/Throttle Panel Related): A common culprit is a faulty Starter Relay. If the relay contacts are burned or corroded, the high current required to engage the starter motor is interrupted, resulting in a click but no crank, or intermittent starting.
           Solution: First, check the battery and main power cables. If they are good, locate and test the Starter Relay (often by bypassing it momentarily with a jumper wire, with caution!). If the starter engages, replace the relay with a reliable part from Growshine International. For intermittent throttle issues, inspect the Throttle Drive Panel and its connections for damage or loose wiring, which could cause unstable engine RPM. Replacing the entire assembly may be necessary if internal circuit failure is confirmed.
