Honour Time Machinery Limited proudly presents a high-performance replacement solution for the Komatsu S6D140 diesel engine, ensuring optimal power and longevity for heavy machinery operations. Our comprehensive component offering includes the meticulously engineered Piston with part numbers 6211-32-2130 and its variant 6212-31-2151 (6211322130, 6212312151). These pistons are crucial for converting the pressure from combustion into rotational energy, making their quality paramount for any Komatsu PC400-8 SAA6D125E-5 Cylinder Liner replacement job. We ensure these key parts meet or exceed OEM specifications, supporting robust performance in excavators and dozers.
Engine durability depends heavily on the quality of the Cylinder Liner and Piston Ring set. Our premium Liner, identified by part number 6211-21-2210 (6211212210), provides the necessary wear surface for the piston assembly. Paired with the specialized Piston Ring Set 6211-31-2031 (6211312031), this combination guarantees excellent compression sealing and effective oil control. Whether you are searching for a Caterpillar C15 cylinder liner replacement or a Cummins N14 connecting rod bearing price, Honour Time is your dedicated diesel engine block casting part supplier, offering comprehensive engine overhaul gasket kit solutions for all major heavy machinery brands including Caterpillar, Cummins, Isuzu, Kubota, Yanmar, and Weichai.

1. Cylinder Liner
The consumable sleeve fitted into the engine block, providing a wear surface for the piston. Example: Komatsu PC400-8 SAA6D125E-5 Cylinder Liner.
2. Piston
The core component that reciprocates within the cylinder, converting combustion force into motion. Example: Caterpillar 330D C9 Piston.
3. Piston Ring
Seals the combustion chamber against the cylinder wall and regulates oil consumption. Example: Cummins QSK60 Piston Ring.
4. Connecting Rod Bearing
The friction-reducing surface between the connecting rod and the crankshaft journal. Example: Isuzu 4HK1 Connecting Rod Bearing.
5. Main Bearing
Supports the crankshaft in the engine block, maintaining its correct rotation position. Example: Kubota V2203 Main Bearing.
6. Thrust Washer
Prevents the crankshaft from moving too far axially within the engine block. Example: Yanmar 4TNV98 Thrust Washer.
7. Turbocharger
A forced induction device that increases power by compressing intake air. Example: Weichai WP12 Turbocharger.
8. Gasket Kit
A collection of various seals needed for a complete engine overhaul or repair. Example: Komatsu PC300-7 S6D114E Overhaul Gasket Kit.
9. Cylinder Head
Sits on top of the cylinder block, sealing the combustion chamber and housing valves. Example: Caterpillar D8T C15 Cylinder Head.
10. Fuel Injector
Precisely atomizes and sprays fuel into the combustion chamber. Example: Cummins ISX15 Fuel Injector.
One frequent issue encountered in heavy equipment like the Komatsu PC200-8 excavator, powered by the SAA6D107E-1 Engine, is the symptom of Excessive Black Smoke and Loss of Power. This often points to a problem with combustion efficiency. The immediate steps for troubleshooting include checking the fuel injection pump pressure and inspecting the fuel injector nozzles for clogging or poor spray patterns. A quick and effective solution is often to replace the faulty fuel injector or clean the nozzle tips, followed by checking for issues with the turbocharger wastegate. Addressing these components, which are part of our extensive catalogue—from Kubota V3307 main bearing set to Isuzu 6HK1 piston ring manufacturer parts—can restore the engine to peak operating condition.
