Understanding your engine's components is key to successful maintenance and repair. Here are 10 critical parts we supply:
Cylinder Liner: A cylindrical insert fitted into the Engine Block to form the cylinder wall. Used in Cummins QSB6.7 Cylinder Liner.
Piston: Reciprocates within the Cylinder to convert combustion pressure into mechanical force. Key part: Caterpillar C9 Piston Assembly.
Main Bearing: Supports the crankshaft, allowing smooth rotation in the Engine Block/Crankshaft Journal. Essential for Komatsu S6D107 Main Bearing Set.
Connecting Rod: Links the Piston to the Crankshaft, converting up-and-down motion into rotation. Found in Isuzu 6BG1 Connecting Rod.
Oil Pump: Circulates engine oil under pressure for lubrication, located in the Engine Block/Oil Sump. Critical for Kubota V2403 Oil Pump.
Turbocharger: Boosts engine power by forcing compressed air into the intake, located on the Exhaust Manifold/Intake System. See Yanmar 4TNV98 Turbocharger Assembly.
Water Pump: Circulates engine coolant between the engine and radiator, located on the Front of the Engine Block. A common replacement is the Weichai WP12 Water Pump.
Fuel Injector: Atomizes and sprays fuel directly into the combustion chamber, located in the Cylinder Head. Used in Cummins N14 Fuel Injector.
Overhaul Gasket Kit: A complete set of seals for major engine maintenance, used on Various parts of the engine. Necessary for the Caterpillar 3406 Overhaul Gasket Kit.
Thrust Washer: Limits the axial (side-to-side) movement of the Crankshaft, located at the Engine Block/Crankshaft. Used in the Isuzu 4HK1 Thrust Washer Set.
A common operational fault in heavy machinery like the Komatsu PC200-8 with the S6D107 engine is sudden overheating under heavy load. This is often caused by a malfunctioning water pump, clogged radiator fins, or low coolant level due to a faulty head gasket. The immediate solution is to stop the engine, allow it to cool, check the coolant level, and inspect the water pump and fan belts for damage or slippage. For a permanent fix, replace the faulty water pump and perform a full cooling system flush.
Regularly check and replace wear parts, especially piston rings and main bearings, according to your engine's service manual. For Yanmar 3TNA80 engines, adhering to scheduled oil changes and using high-quality piston ring sets significantly reduces friction and prevents premature engine failure. Always use overhaul gasket kits during any major repair to ensure a perfect, leak-free seal.
