Frequently Asked Questions

Which Doosan DX300 hydraulic pump do I need?

The correct main hydraulic pump for a Doosan DX300 depends on the variant suffix. The DX300LC and DX300LL use part number K1006550, while the DX300LC-3 uses part number 400914-00395B. Check the model plate and serial number on your machine before ordering so you get the right pump.

Do the Doosan DX300LC and DX300LC-3 use the same main hydraulic pump?

No, the DX300LC and the DX300LC-3 use different main hydraulic pumps. The DX300LC shares part number K1006550 with the DX300LL, and the third generation DX300LC-3 takes part number 400914-00395B. Matching the variant suffix on your machine is the easiest way to avoid ordering the wrong pump.

Which main hydraulic pump fits a Doosan DX225 excavator?

Each DX225 variant uses its own main hydraulic pump. Broken Tractor offers part number 400914-00165E for the DX225LC-3, K1029621 for the DX225LL log loader, and K1014967A for the DX225NLC narrow carriage machine. Confirm your serial number and variant suffix before ordering, or call (800) 909-7060 and the parts team can help verify fitment.

How does a Doosan excavator main hydraulic pump work?

The main hydraulic pump supplies oil flow to all of the excavator's work and travel circuits. That flow powers the boom, arm, bucket and travel functions, which is why the pump is often called the heart of the hydraulic system. A failing main pump can affect every hydraulic function on the machine, not just one circuit.

How do I make sure a replacement Doosan excavator hydraulic pump will fit?

Match your machine's model, variant suffix and serial number to the part number before ordering. Broken Tractor carries direct-fit main hydraulic pumps for the DX225LC-3, DX225LL, DX225NLC, DX300LC, DX300LL and DX300LC-3, and each one is listed with its reference part number. If your old pump's part number matches one of these, that is the surest way to confirm the right replacement.
