Unrivaled Performance: Piston and Liner Set for Caterpillar 3516B Mining Engines

The powerful Caterpillar 3516B engine is an absolute necessity for enormous equipment, such as large Haul Trucks and Mining Excavators, especially in harsh environments like Siberian Mining Sites. These engines operate under continuous high load and must tolerate extreme temperature swings. Honour Time Machinery Limited supplies certified, high-end CAT engine parts, engineered to ensure longevity and peak performance in these demanding conditions, minimizing downtime for your operation.

We are featuring the core cylinder components needed for a complete engine overhaul:

• High-Performance Piston Numbers: 172-0919 (1720919) / 155-5271 (1555271)

• Hardened Cylinder Liner Number: 211-7826 (2117826)

Critical Engine Component Definitions and Applications for Heavy Machinery

• Cylinder Liner: A replaceable sleeve that forms the cylinder bore. Caterpillar D11T C175-16 Cylinder Liner.

• Turbocharger: Increases engine power by compressing the intake air. Cummins QSK60 Engine Turbocharger.

• Main Bearing: Supports the main journals of the crankshaft. Komatsu PC1250-8 SAA6D170E-5 Main Bearing.

• Fuel Injector: Delivers atomized fuel into the combustion chamber. Isuzu 6UZ1 Engine Fuel Injector.

• Piston Ring: Provides gas-tight seal and regulates oil consumption. Kubota D1105 Engine Piston Ring.

• Water Pump: Circulates coolant through the engine's cooling system. Yanmar 4TNV106 Water Pump.

• Connecting Rod: The mechanical link between the piston and the crankshaft. Weichai WP12 Connecting Rod.

• Cylinder Head: Seals the top of the cylinder block and houses the valve train. Caterpillar 3516B Cylinder Head.

• Oil Pump: Circulates lubricating oil under pressure. Komatsu WA600-8 SAA6D140E-5 Oil Pump.

• Thrust Washer: Controls the axial (end-play) movement of the crankshaft. Cummins KTA38 Engine Thrust Washer.

Fault Analysis: Loss of Oil Pressure in Isuzu 4BG1 Excavator

A sudden or gradual loss of oil pressure in an Isuzu 4BG1 engine (common in small to medium excavators like the Isuzu EX100 can be catastrophic. The pressure drop often indicates critical wear in the lubrication system.

Detailed Solution: The first step is to confirm the pressure reading with a mechanical gauge. If the pressure is genuinely low, the most common causes are a worn Oil Pump (especially the gears, severely worn Main Bearings or Connecting Rod Bearings (allowing excessive oil escape), or a blocked oil suction tube/strainer. A complete engine rebuild should check all these components. We supply Isuzu 4BG1 full Engine Gasket Sets, high-flow Oil Pumps, and precision Bearing Sets to restore the correct oil pressure and prevent expensive engine seizure. Immediate action is required to prevent component failure.
