advantage

• 38cc variable displacement piston design with load sensing control, automatically adjust flow to match D61EX-15 engine heat demand, reduce idle power loss and fuel consumption.
• Thickened cast iron pump body with high structural rigidity, withstand strong vibration and impact during bulldozer pushing and climbing operations.
• Hardened alloy piston group delivers excellent wear resistance, stable performance under slight hydraulic oil contamination on construction sites.
• FKM composite sealing assembly resists high temperature and oil aging, effectively prevents internal leakage and shaft oil seepage.
• Precise load-sensing control provides stable flow output, ensures fan speed responds quickly to temperature changes.
• Interchangeable with 708-1S-00240, OEM mounting dimensions for direct bolt-on replacement without pipe modification.
• All pumps undergo full-condition bench tests for pressure and flow performance, guaranteeing long-term reliable operation in earthmoving sites

FAQ

Q1: Which equipment does 708-1S-00241 fan pump fit?
A1: This hydraulic fan pump is specially applicable to Komatsu D61EX-15, D61PX-15 and D65EX-15 bulldozers. It is recommended to confirm the equipment serial number before purchasing to ensure accurate matching.

Q2: What is the core function of this fan pump?
A2: It is the hydraulic power source of bulldozer cooling system. It converts mechanical power from engine into hydraulic power, supplies pressurized oil to drive fan motor, adjusts output flow dynamically to control fan speed, and stabilizes engine coolant and hydraulic oil temperature to avoid overheating during heavy-duty operation.

Q3: What are the typical failure symptoms of aging or worn fan pump?
A3: Common faults include insufficient pump output flow leading to low fan speed and high temperature; unstable flow causing fan jitter; abnormal internal noise; internal leakage reduces pump output power; shaft seal oil seepage; slow flow response when temperature rises.

Q4: What inspections need to be completed before installing a new fan pump?
A4: First, check hydraulic oil quality and cleanliness, replace deteriorated oil and filter elements. Second, inspect cooling system pipeline, relief valve and control valve for blockage, damage or stuck spool. Fully flush the hydraulic tank and pipelines to remove metal debris, and bleed air after installation.
