Honour Time Machinery Limited is your premier source for high performance engine parts essential for a full excavator engine rebuild. We highlight the core components for the Caterpillar 320C/S6K engine: the Piston Number 297-7753 (2977753) and the corresponding Cylinder Liner Number 5I7523. Together, these form the essential engine overhaul components for the combustion chamber. Although the specific piston ring number is not listed, we supply the complete piston ring set to ensure a perfect seal. As diesel component specialists, we ensure all components meet or exceed genuine quality engine parts standards for maximum durability and performance.
We are global leaders in providing wholesale engine components and facilitating engine assembly wholesale for heavy-duty applications.
Our expansive parts catalog covers: Cummins, Komatsu, Caterpillar, Isuzu, Kubota, Yanmar, and Weichai engines. Key products for machinery maintenance components include: pistons, piston rings (piston rings export), main bearings (main bearing set), connecting rod bearings (connecting rod bearing), thrust washers (thrust washer), overhaul gasket kits (engine gasket kit), diesel pumps, fuel injectors, crankshafts, turbochargers (turbocharger supplier), water pumps, oil pumps, cylinder blocks, cylinder heads, and connecting rods. We also supply for bulldozer engine parts and specialize in generator set rebuild parts.
Diesel Pump: Location: Mounted on the Engine Block. Function: Delivers high-pressure fuel. Cummins ISX15 Engine - Diesel Pump.
Piston Ring: Location: Grooves on the Piston. Function: Seals combustion and regulates oil. Komatsu PC200-10 - SAA6D107E-3 Engine - Piston Rings (piston rings export).
Cylinder Liner: Location: Inside the Cylinder Block. Function: Provides the internal surface for piston travel. Caterpillar 320C - S6K Engine - Cylinder Liner 5I7523.
Thrust Washer: Location: Sides of Crankshaft Main Bearing. Function: Controls crankshaft axial movement. Isuzu 6HK1 Engine - Thrust Washer.
Turbocharger: Location: Exhaust Manifold. Function: Compresses intake air for more power. Kubota U55-4 - V2607 Engine - Turbocharger Supplier.
Connecting Rod Bearing: Location: Inside the Connecting Rod. Function: Allows the rod to rotate freely on the crankshaft. Yanmar VIO50 - 4TNV88 Engine - Connecting Rod Bearing.
Cylinder Head: Location: Top of the Engine Block. Function: Forms the combustion chamber. Weichai WP13 Engine - Cylinder Head.
Oil Pump: Location: Sump area. Function: Circulates engine oil. Caterpillar D6K2 - C6.6 Engine - Oil Pump.
Crankshaft: Location: Bottom center of the Engine Block. Function: Converts piston motion into rotation. Cummins QSB4.5 Engine - Crankshaft.
Water Pump: Location: Engine Block. Function: Circulates coolant. Komatsu GD555-6 - SAA6D107E-3 Engine - Water Pump.
Persistent white smoke from a machine using the Isuzu 6HK1 Engine (e.g., in a heavy excavator) usually indicates that water or coolant is entering the combustion chamber, or an issue with the timing of the fuel injection. It's distinct from black (fuel) or blue (oil) smoke.
**Solution:** The most common cause is a leaking cylinder head gasket or a crack in the cylinder head. A pressure test on the cooling system can confirm this. Repair involves disassembling the engine top-end, inspecting the cylinder liners (cylinder liner supplier) for damage, and replacing the overhaul gasket kit. If the Caterpillar 320C/S6K Liner Kit (Piston 297-7753, Liner 5I7523) is being used, ensure the block and head surfaces are perfectly flat before installing the new gasket to prevent immediate re-failure and ensure reliable excavator engine repair.
