Cylinder Liner
A removable metal tube inserted into the cylinder block. Caterpillar D8R Liner is crucial for wear resistance. (Engine: Caterpillar D8R)
Connecting Rod Bearing (Con Rod Bearing)
Fitted between the connecting rod and the crankshaft journal. The Cummins KTA38 Con Rod Bearing supports immense force. (Engine: Cummins KTA38)
Thrust Washer
Used to control the axial movement (front-to-back) of the crankshaft. Essential in the Komatsu 6D125 Thrust Washer assembly. (Engine: Komatsu 6D125)
Turbocharger
A forced induction device that increases engine power by forcing extra air into the combustion chambers. The Weichai WP12 Turbocharger is common in trucks. (Engine: Weichai WP12)
Water Pump
Circulates coolant through the engine's cooling system to maintain optimal temperature. A vital component in the Isuzu 4HK1 Water Pump system. (Engine: Isuzu 4HK1)
Fuel Injector
Sprays a precise amount of fuel into the engine cylinders. Precision is key in the Yanmar 4TNV94 Fuel Injector. (Engine: Yanmar 4TNV94)
Oil Pump
Circulates engine oil under pressure to lubricate bearings and pistons. Essential for a healthy Kubota V2203 Oil Pump. (Engine: Kubota V2203)
Cylinder Head
Sits above the cylinder block, forming the combustion chamber. Houses the valves and spark/glow plugs. Critical in the Caterpillar C7 Cylinder Head assembly. (Engine: Caterpillar C7)
Main Bearing
Supports the crankshaft in the cylinder block, allowing it to rotate. Must be precise for the Komatsu SAA6D107 Main Bearing. (Engine: Komatsu SAA6D107)
Overhaul Kit (Gasket Set)
A comprehensive set of gaskets and seals needed for a full engine strip-down and rebuild. Used extensively in Cummins ISX15 Overhaul Kit projects. (Engine: Cummins ISX15)
Troubleshooting: Addressing Abnormal Oil Consumption
Fault Scenario: Komatsu PC400-8 Engine SAA6D125 Oil Consumption
If your Komatsu PC400-8 excavator, powered by the SAA6D125 engine, exhibits excessive oil consumption without external leaks, the primary suspects are the piston rings, valve stem seals, or turbocharger seals.
Solution & Maintenance Plan:
Diagnosis: Conduct a cylinder leak-down test. High leakage past the piston is a clear indicator for a new piston ring set (like our ISUZU 6RB1 Piston Ring Kit alternative).
Correction: Install genuine-spec piston and piston ring sets. Ensure the cylinder liner bore is within tolerance.
Preventative Maintenance: Always use the correct viscosity and quality oil. Change the oil and filter according to the SAA6D125 maintenance schedule (typically every 250-500 hours) to prevent sludge buildup which can seize the oil control ring.
