Using Komatsu WA250-5L Hydraulic System Parts

The Komatsu WA250-5L Hydraulic System Parts catalog section brings together 48 published assembly listings for identifying aftermarket replacement parts. Start with the component or assembly that matches your machine, then use its diagram and part numbers to narrow the selection.

Available listings include 4-Gear Pump (Brake And Cooling Fan Pump), 4-Gear Pump (Transfer Lubricating Pump), Auto-Reverse Fan Piping (Waste Handler), Control Valve (2-Spool) (Ecss And Jrb) and Control Valve (3-Spool) (Ecss And Jrb). These are examples of the published coverage, not a statement that every configuration or service component is included.

For hydraulic replacement parts, compare the listed circuit, cylinder, valve or hose application wherever identified in the selected assembly. Retain connection and configuration notes when requesting a quote rather than relying on appearance alone.

Open a WA250-5L assembly to compare the machine serial range, component description, quantities and listed options. You can then select available store matches for the cart or prepare a request for a quote with the part numbers and quantities you need.
