⚠ MANUFACTURER DIRECT: Custom Cylinder Liner Production & Global Export ⚠
Honour Time Machinery Limited operates as a source factory, allowing for the bespoke customization and precise manufacturing of engine components, particularly Cylinder Liners and compatible Piston Kits. We ensure OEM-level quality components for QSX15 and other heavy-duty engines, offering superior value and reliability through our direct foreign trade export channels.
High-Strength Cummins QSX15 Piston Kit Selection
The Cummins QSX15 engine is widely utilized in demanding applications, such as large Komatsu Dozers and Caterpillar Mining Trucks throughout the Asia Pacific region. Utilizing the correct Piston Assembly is vital for managing the high thermal and mechanical stresses within the combustion chamber.
We provide multiple high-strength Piston variants for the QSX15, crucial for a complete engine rebuild. The critical Piston Part Numbers available are:
Engine Model: QSX15
Piston Set 1: 4923747 (4923747) and 4089898 (4089898)
Piston Set 2: 4298992 (4298992) and 2882120 (2882120)
Overhaul Compatibility: These pistons require specific Cylinder Liners and Piston Ring Sets (not provided, but supplied by us) to complete a proper QSX15 Engine Overhaul Kit.
Ensure your heavy equipment uses the latest spec Piston 4923747 for maximum engine durability.

10 Key Component Definitions and Equipment Applications
A glossary of essential engine and machinery parts, vital for field maintenance and repair:
Fuel Injector: Atomizes and injects fuel into the combustion chamber. Position: Installed in the Cylinder Head. Example: Cummins QSX15 Fuel Injector (Used in Large Excavator).
Alternator: Converts mechanical energy into electrical energy to charge the battery. Position: Mounted on the Engine Block, driven by a belt. Example: Caterpillar C15 Alternator (Used in Off-Highway Truck 777G).
Engine Oil Cooler: Reduces the temperature of the circulating engine oil. Position: Attached to the Engine Block or Filter Housing. Example: Komatsu SAA6D140E-5 Oil Cooler (Used in PC450 Excavator).
Fuel Filter (Primary/Secondary): Removes contaminants from the diesel fuel. Position: In the fuel line between the Fuel Tank and Injection Pump. Example: Isuzu 6BG1 Fuel Filter (Used in F-Series Truck).
Tappet (Lifter): Follows the camshaft lobe profile to activate the pushrod/valve. Position: In the Cylinder Block or Cylinder Head. Example: Kubota V3800 Tappet (Used in Tractor M7040).
Exhaust Valve: Allows burnt gases to exit the cylinder. Position: Inside the Cylinder Head. Example: Yanmar 4TNV88 Exhaust Valve (Used in Mini Loader).
Flywheel Ring Gear: The toothed ring engaged by the starter motor. Position: Around the outer edge of the Flywheel. Example: Weichai WD10 Ring Gear (Used in SD32 Bulldozer).
Vibration Damper: Absorbs and dampens torsional vibrations in the crankshaft. Position: Attached to the front of the Crankshaft. Example: Cummins 4BT Vibration Damper (Used in Backhoe Loader).
Oil Sump Gasket (Oil Pan Gasket): Seals the joint between the oil pan and engine block. Position: Between the Oil Pan and Cylinder Block. Example: Caterpillar C7 Oil Pan Gasket (Used in Motor Grader).
Cooling Fan: Draws air through the radiator to cool the coolant. Position: Mounted on the Water Pump or Fan Hub. Example: Komatsu PC300-7 Cooling Fan (Used in Hydraulic Excavator).
Diagnostic Corner: Engine Overheating Fault on Heavy Equipment
Engineering Fault: Intermittent Overheating and Low Coolant Alarm
Equipment/Model: Komatsu HD465-7 Dump Truck with SAA6D170E Engine.
Fault Description: The engine temperature gauge rises rapidly during uphill hauling under load, triggering a high-temperature shutdown warning. Coolant level appears normal at idle but drops immediately upon engine shutdown.
Root Cause: Malfunction of the Water Pump Impeller (corrosion or slippage on the shaft) resulting in insufficient coolant circulation at high RPM, or a partially blocked Oil Cooler or Radiator Core causing flow restriction.
Treatment/Solution: The Cooling System must be pressure tested and flow checked. If the Water Pump output is low, it requires replacement. If flow is restricted, the radiator and coolers must be professionally cleaned or replaced. Preventative maintenance includes regular coolant additive testing and using high-quality components, which, for models like QSX15, ensures the Pistons 4923747 and 4298992 remain within optimal operating temperature ranges.
Trust Honour Time Machinery for reliable replacement parts, including the durable Piston 4089898 and 2882120, to keep your QSX15 running efficiently.
