The Core of Power: Piston and Liner Set for Caterpillar C27/C32 Engines

The powerful Caterpillar C27 and C32 engines are indispensable in heavy-duty applications, particularly in South American mining operations, which often involve challenging high-altitude and sustained high-load conditions. These environments demand engine components that can guarantee both performance and longevity. Honour Time Machinery Limited is a dedicated supplier of certified, heavy-duty CAT engine parts engineered for reliability in the most extreme working conditions.

We are featuring the high-spec piston crucial for an engine overhaul:

• Heavy-Duty Piston Number: 319-6717 (3196717)

• Cylinder Liner: Compatible CAT C27/C32 Component (Piston and liner sold as a precision-matched kit)

Critical Engine Component Definitions and Applications for Heavy Machinery

• Cylinder Liner: Forms the wear-resistant surface for the piston. Caterpillar 777G C32 Cylinder Liner.

• Turbocharger: Increases engine power by compressing the intake air. Cummins QSB3.3 Engine Turbocharger.

• Main Bearing: Supports the main journals of the crankshaft. Komatsu D155AX-8 SAA6D140E-5 Main Bearing.

• Fuel Injector: Delivers atomized fuel into the combustion chamber. Isuzu 4HK1 Engine Fuel Injector.

• Piston Ring: Provides gas-tight seal and regulates oil consumption. Kubota V1505 Engine Piston Ring.

• Water Pump: Circulates coolant through the engine's cooling system. Yanmar 3TNV88 Water Pump.

• Connecting Rod: The mechanical link between the piston and the crankshaft. Weichai WP7 Connecting Rod.

• Cylinder Head: Seals the top of the cylinder block and houses the valve train. Caterpillar C27 Cylinder Head.

• Oil Pump: Circulates lubricating oil under pressure. Komatsu PC200-8 SAA6D107E-1 Oil Pump.

• Thrust Washer: Controls the axial (end-play) movement of the crankshaft. Cummins M11 Engine Thrust Washer.

Troubleshooting: Engine Knocking in Komatsu PC400-8 Excavator

A persistent engine knocking sound in a Komatsu PC400-8 Excavator (SAA6D125E-5 engine) often signals a critical failure in the lower end of the engine. The most common cause of a severe knock is excessive clearance or failure of the Connecting Rod Bearings or Main Bearings, which allows the Connecting Rod or Crankshaft  to impact the cap or block.

Detailed Solution: If knocking occurs, the engine must be immediately shut down to prevent total destruction. A detailed internal inspection of the lower end is required, typically starting with removing the oil pan. Inspect the Connecting Rod Bearings and Main Bearings for signs of severe wear (copper or bronze visible) or spinning. If bearing damage is confirmed, a full rebuild is necessary, involving replacement of all Bearings, and potentially the Crankshaft and Connecting Rods if surfaces are damaged. We supply full sets of Komatsu SAA6D125E-5 precision-machined Bearings and Crankshafts to restore proper clearances and eliminate dangerous engine knock.
