Technical Knowledge Hub: Component Definitions

Understanding your parts is vital for maintenance. Here are 10 key component definitions:

• Bolzen (Bolt): A threaded fastener used to join two or more components, often under tension.
  Location: Engine block, chassis, or machinery frame.
  Example: STILL RX70-30 Bolzen (Attaching counterweight to chassis).

• Pressure Sensor: A device that measures pressure (liquid or gas) and converts the reading into an electrical signal.
  Location: Engine intake manifold or fuel rail.
  Example: VOLVO FH16 Pressure Sensor (Measuring fuel pressure).

• ABS Sensor (Anti-lock Braking System Sensor): A device that monitors wheel speed and sends data to the ABS control module to prevent wheel lock-up during braking.
  Location: Wheel hub/axle.
  Example: MAN TGS ABS Sensor (Monitoring front wheel speed).

• Exhaust Gas Temperature Sensor (EGT Sensor): A thermocouple located in the exhaust stream to measure the temperature of exhaust gases.
  Location: Exhaust manifold or DPF inlet/outlet.
  Example: DAF XF EGT Sensor (Pre-DPF temperature monitoring).

• Throttle Position Sensor (TPS): A sensor used to monitor the throttle valve position in the engine's air intake system.
  Location: Throttle body.
  Example: VOLVO L90H Throttle Position Sensor (Regulating air intake on wheel loader).

• Oil Level Sensor: An electronic device that monitors the quantity of engine oil in the sump.
  Location: Engine oil pan/sump.
  Example: MERCEDES-BENZ Actros Oil Level Sensor (Preventing engine damage from low oil).

• Turbocharger: A turbine-driven forced induction device that increases an engine's efficiency and power by forcing extra air into the combustion chamber.
  Location: Engine exhaust manifold.
  Example: Caterpillar D6T Holset Turbocharger (Boosting engine performance on dozer).

• Hydraulic Pump: A component that converts mechanical energy into hydraulic energy, generating fluid flow necessary to power hydraulic components.
  Location: Engine accessory drive.
  Example: Komatsu PC200-8 Hydraulic Pump (Generating power for excavator arm movement).

• Steering Knuckle: The component that contains the wheel hub or spindle and attaches to the suspension and steering components.
  Location: Front axle assembly.
  Example: John Deere 6155M Steering Knuckle (Pivot point for front-wheel steering on agricultural tractor).

• Fuel Injector: An electrically controlled valve that delivers a precise amount of fuel into the engine combustion chamber.
  Location: Cylinder head/fuel rail.
  Example: Ford F-150 Fuel Injector (Precise fuel delivery for automotive engine).
