Unmatched Reliability for Caterpillar CAT385C & CAT390D Excavators

Searching for a premium-grade replacement hydraulic pump for your Caterpillar CAT385C or CAT390D heavy-duty excavator? Our main piston pump assembly (often referred to as the Main Pump Assembly or Plunger Pump) delivers the critical power and performance your machinery demands. We specialize in providing high-quality, durable alternatives to the OEM Caterpillar Parts, ensuring maximum uptime and efficiency on your construction or mining site.

The Caterpillar Excavator Hydraulic Pump is the heart of your machine's operating system. Failure to replace this component with a reliable unit can lead to catastrophic downtime. We supply assemblies compatible with a range of key CAT part numbers, including: 155-9205, 334-9990, 295-9674, 151-6645, 222-8316, 200-3269, and 310-9486. Trust our quality for your heavy equipment repair and maintenance needs.

A Deep Dive into Heavy Machinery Components

Understanding the vital components of heavy machinery is crucial for longevity and operational success. Our expertise extends beyond Caterpillar Parts. Here are 10 key terms from the world of construction and mining equipment spare parts:

• Rock Drill Piston: Located within the rock drill (drifter) on a boom, this component impacts the shank adapter to transfer energy to the drill string. Sandvik Ranger DX800 - Rock Drill - Piston.

• Tramming Motor: The hydraulic motor on the undercarriage or chassis that provides drive power for machine movement (tramming). Atlas Copco Boomer L2D - Tramming Motor.

• Drifter Accumulator: Mounted on the rock drill (drifter), it dampens pressure pulsations in the hydraulic system to protect seals and components. Epiroc SmartROC T45 - Drifter - Accumulator.

• Slew Bearing (Swing Bearing): A large, circular bearing connecting the house (upper structure) to the undercarriage, enabling 360-degree rotation. Used on all major excavators like the CAT 390D Excavator Slew Bearing.

• Track Shoe: Individual segments bolted to the track chain, providing traction and flotation for crawler machines. Found on Komatsu PC400 Track Shoe.

• Torque Converter: Located between the engine and transmission in many loaders/haul trucks, it transmits and multiplies engine torque. Found on a Volvo L350F Wheel Loader Torque Converter.

• Cylinder Block (for Piston Pump): The rotating barrel inside the hydraulic piston pump (like the CAT 385C Main Pump Assembly Cylinder Block) that houses the pistons.

• Turbocharger: Bolted to the engine manifold, it forces compressed air into the engine to increase power and efficiency. Used extensively in Cummins QSK60 Engine Turbocharger.

• Valve Plate: A stationary plate inside a hydraulic piston pump (e.g., 155-9205) that controls the flow of oil into and out of the cylinder block.

• Feed Beam: The structural component on drilling rigs that guides and supports the rock drill and drill string during the drilling process. Sandvik DL431-7C - Feed Beam.
