Technical Component Glossary and Diagnostics

10 Essential Engineering Parts Explained:

  1. Cylinder Liner (3803544): Forms the durable wall of the cylinder for the piston's operation. Cummins B3.3 Cylinder Liner 3803544.

  2. Piston (4955416): Translates combustion energy into mechanical force. Caterpillar D6T Piston 4955416.

  3. Main Bearing (Crankshaft Bearing): Supports the crankshaft along its length within the engine block. Weichai WP7 Main Bearing Set.

  4. Turbocharger: Increases engine efficiency by compressing air using exhaust gases. Isuzu 6UZ1 Turbocharger.

  5. Connecting Rod: Links the Piston to the Crankshaft. Kubota V2607 Connecting Rod.

  6. Fuel Pump (Diesel Pump): Delivers fuel to the injectors under high pressure. Yanmar 3TNV88 Fuel Pump.

  7. Cylinder Head Gasket: Seals the combustion chamber between the head and block. Komatsu SAA6D107 Cylinder Head Gasket.

  8. Oil Pump: Circulates lubricating oil throughout the engine under pressure. Caterpillar C13 Oil Pump Mechanism.

  9. Exhaust Manifold: Collects exhaust gases from the cylinders before they enter the turbocharger or exhaust pipe. Cummins QSB4.5 Exhaust Manifold.

  10. Stop Solenoid: Controls the flow of fuel to stop the engine. Komatsu PC70-8 Stop Solenoid.


Engineering Machinery Fault & Solution:
           Equipment/Model: Caterpillar 305E Mini Excavator (C1.5 Engine) is overheating quickly with bubbling in the radiator.
           Solution: Bubbling often signifies exhaust gases entering the cooling system, indicating a serious internal leak. The most likely causes are a faulty Cylinder Head Gasket, or a crack in the Cylinder Head or Liner. A cooling system pressure test and cylinder leak down test must be performed. If leakage is confirmed, the engine must be dismantled, and components like the Liner 3803544 must be inspected and replaced if necessary to prevent permanent engine damage.
