Specifications
| Details | 708-1S-11190 Hydraulic Pump Assembly – Komatsu Cooling Fan Pump The 708-1S-11190 hydraulic pump powers the cooling fan circuit on specific Komatsu machines. This hydraulic fan pump supplies pressurized oil to the fan motor. The motor then drives the engine cooling fan. Proper airflow keeps radiator temperatures stable during demanding work cycles. A failing fan pump lets engine and hydraulic oil temperatures rise quickly. That rise leads to derated performance or costly downtime. Compatibility and Fit This pump most commonly fits the Komatsu WA380-6 wheel loader. The WA380-6 hydraulic system uses a variable piston pump and a Closed-centre Load Sensing System (CLSS). That system delivers responsive, efficient hydraulic power. The WA380-6 relies on a hydraulically driven cooling fan. The 708-1S-11190 assembly powers that fan circuit. Listings also confirm fitment for the Komatsu D65PX-15 excavator/dozer platform. On that machine, the same fan-pump assembly drives the cooling fan motor. Why This Replacement Pump The 708-1S-11190 matches the mounting points of the original unit. It also matches port orientation and displacement characteristics. As a direct-fit replacement, it installs without modification. This pump is an aftermarket alternative to dealer-only components. It offers a cost-effective path to restoring cooling performance. Fit and function remain uncompromised. Before ordering, always cross-check your machine’s serial number. Also check the part number stamped on the failed pump. Komatsu used several fan-pump variants across WA380-6 and D65PX-15 production runs. Related Parts and Further Reading If you service the cooling circuit, you may also need the hydraulic fan motor. This pump drives that motor. Browse our Komatsu hydraulic fan motor category for matching components. Komatsu’s fan-pump circuit integrates with the broader hydraulic system. For details, see the Komatsu patent documentation on operating oil supplying devices for construction machines . Official WA380-6 specifications include hydraulic system pressure and flow data. Refer to the Komatsu WA380-6 catalog page on DirectIndustry . Komatsu’s regional equipment pages also describe the reversible hydraulic cooling fan feature. That feature matters when you diagnose fan-circuit faults. |
