Understanding the role of each component is vital for proper maintenance. Here are 10 key parts and their applications in equipment from our main brands:
Cylinder Liner (3055099): Installed in the Cylinder Block. CUMMINS NT855 Cylinder Liner 3055099.
Piston (3074494): Located within the Cylinder Liner, converts gas pressure into mechanical force. CATERPILLAR 320D Piston 3074494.
Piston Ring: Sits in the Piston grooves, seals combustion gas and controls oil. KOMATSU PC400-7 Piston Ring Set.
Crankshaft: In the Cylinder Block (Lower), converts reciprocating motion to rotational motion. ISUZU 6BG1 Crankshaft.
Connecting Rod: Links the Piston to the Crankshaft. KUBOTA V2203 Connecting Rod.
Turbocharger: Attached to the Exhaust Manifold, increases air density for combustion. YANMAR 4TNV94 Turbocharger.
Injector: Installed in the Cylinder Head, atomizes and sprays fuel. WEICHAI WP7 Injector.
Water Pump: Mounted on the Engine Front/Block, circulates coolant. CUMMINS M11 Water Pump.
Crankshaft Bearing (Main Bearing): Supports the Crankshaft in the block. CATERPILLAR D6N Main Bearing.
Oil Pump: Located in the Oil Pan/Engine Block, circulates engine oil. KOMATSU S6D107E Oil Pump.
Common Engine Failure & Solution Example (Part 9):
Equipment Model: KOMATSU PC360-7 Excavator with CUMMINS QSC Engine
Fault: Excessive blue smoke and high oil consumption after 5000 hours of operation.
Diagnosis & Solution: Blue smoke and oil consumption typically indicate combustion oil entering the cylinder, often due to worn piston rings or cylinder liners. For the QSC engine, a full in-frame overhaul is recommended. The solution is to replace the complete cylinder kit, including the Piston (e.g., 3074494 equivalent), Piston Rings, and Cylinder Liner (e.g., 3055099 equivalent), along with main and con rod bearings and a full gasket set. Using OEM-spec parts from a reliable supplier like Honour Time Machinery Limited is crucial to restore compression and minimize oil blow-by.
