In StockLQ10V00018F1 Hydraulic Pump Assembly for Kobelco SK260LC-8 excavator (K3V112DTP1L9R-YT1K). This model-specific pump carries the YT1K servo regulator configuration matched to the SK260LC-8 electronic control system. Supplying the correct regulator variant eliminates the pump-controller compatibility issues that cause hunting or power-limit errors when generic K3V112 pumps are substituted.

Pump regulator variant matches SK260LC-8 electronic power-limit control signal specification, preventing the hunting or error codes that occur when non-YT1K pumps are installed.
K3V112DTP-series rotating group rated for SK260LC-8 maximum system pressure, suitable for heavy rock-breaking and simultaneous multi-function operation.
Hydraulic port sizes, SAE flange configuration and engine flange bolt circle confirmed for SK260LC-8 for direct installation without adaptor blocks.
New cylinder block, pistons, piston shoes and valve plate restore original volumetric efficiency, reducing fuel consumption back to SK260LC-8 factory specification.
FAQ
Q: Why is the YT1K regulator variant important for SK260LC-8?
A: The SK260LC-8 electronic control unit sends a specific current signal to the YT1K regulator for power limit adjustment. Using a non-YT1K regulator causes incorrect swashplate response, resulting in pump hunting, ECU error codes and sub-optimal fuel efficiency.
Q: How do I confirm LQ10V00018F1 is the correct pump for my SK260LC-8?
A: Check the pump model plate on the existing pump reads LQ10V00018F1 and the regulator label reads K3V112DTP1L9R-YT1K. Provide the SK260LC-8 serial number to our team for cross-reference.
Q: Should I flush the hydraulic circuit before fitting the LQ10V00018F1?
A: Yes. SK260LC-8 hydraulic circuits accumulate metal debris when the old pump deteriorates. Flush all lines, replace hydraulic filters and check the tank breather before connecting the new pump.
Q: What break-in period is recommended for LQ10V00018F1?
A: Run at low pressure and partial load for 2 hours, check all port connections for leaks, then increase to full load progressively over the next 8 hours. Replace the return filter element at 50 hours.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
