Description

Main Hydraulic Piston Pump (fits JCB) - OEM KNJ1817

High-quality main multi-piston hydraulic pump designed for JCB tracked and wheeled excavators, particularly for the popular models of the JS 110 and JS 130 series. It constitutes the "heart" of the machine's entire hydraulic system, responsible for generating the high pressure and oil flow necessary for the precise operation of the boom, bucket, upper structure swing, and travel system. The solid construction guarantees maximum efficiency, smooth machine movements, and a long service life during continuous operation under heavy loads.

What does OEM quality mean for this pump?

  • Original Equipment Manufacturer (OEM) specification: The part was manufactured to the exact same rigorous standards, dimensional tolerances, and material specifications as the components used for the initial assembly at the JCB factory.
  • Factory operating parameters: An OEM pump guarantees a precisely matched oil output (flow) and maximum working pressure. This translates directly into restoring the factory bucket breakout force, full speed of arm movements, and proper driving dynamics.
  • Hassle-free installation (Plug & Play): Identical mounting hole spacing, flange diameters, connection threads, and splines on the drive shaft completely eliminate installation problems.
  • Maximum durability and safety: The use of high-quality alloys to build the piston section and the control plate minimizes the risk of seizing and metal shaving generation. This protects the costly remainder of the hydraulic system (control valves, travel motors, cylinders) from contamination.

Technical Specification:

  • Part type: Main hydraulic pump.
  • Design type: Piston pump (multi-piston).
  • Application: Powering the main hydraulic system of the excavator.
  • Quality class: OEM (Original Equipment Manufacturer).
  • Part Number: KNJ1817.

JCB Machine Compatibility:

Workshop Tip: Replacing the main pump is an advanced repair that requires absolute cleanliness of the entire system. Before installing the new pump, it is strictly necessary to flush the hydraulic lines and cylinders, and replace all hydraulic filters and oil with new ones that comply with the rigorous JCB specifications. Leaving any metal shavings from the old (damaged) pump will lead to the immediate seizure of the new unit. Before starting the engine for the first time, do not forget to fill the housing of the new pump with clean hydraulic oil (priming/bleeding) to prevent catastrophic dry running.
