206 60 X1261 hydraulic pump

206-60-X1261 Hydraulic Main Pump for Komatsu PC220-5 with HPV90 variable displacement piston pump. New rotating group and matched valve plate eliminate the bypass that drives up oil temperature. Product Specifications Part Number 206-60-X1261 / 708-25-04061 / 708-25-04022 / 708-25-04021 Part Name Excavator Hydraulic Main Pump (Piston Pump) Compatible Brand Komatsu (HPV90 Piston Pump) Applicable Models PC220-5 Excavator Application Main hydraulic pump for PC220-5 excavator all-function operation Material High-strength alloy steel Product Color Metallic industrial finish Working Temperature -25°C~+60°C Key Function Generates main hydraulic flow and pressure for PC220-5 work circuits Condition 100% New Aftermarket OEM Quality Packaging Wooden Case Reinforced Carton Neutral Packing Customized Box Key Features & Advantages Precision Rotating Group The 206-60-X1261 cylinder block, pistons and piston shoes are machined to HPV90 OEM clearance, restoring volumetric efficiency and cutting the internal bypass that drives oil temperature up on the PC220-5. Matched Barrel and Valve Plate Barrel face and valve plate are surface-matched to Ra 0.2 during assembly, eliminating the break-in leakage phase that reduces new-pump efficiency on the PC220-5 HPV90 circuit. Factory-Calibrated Regulator The HPV90 regulator is pre-set to the PC220-5 engine power curve, preventing engine overload during combined boom, swing and travel demand without field adjustment. Drop-In {model} Fit 206-60-X1261 port configuration, flange bolt circle and spline engagement are confirmed for the PC220-5, providing direct bolt-on installation without adaptor blocks or hose rerouting. FAQ Q: What symptoms indicate the 206-60-X1261 pump needs replacing on a PC220-5?A: Main circuit pressure falls below specification on a gauge test, all functions slow simultaneously at rated engine speed, HPV90 case-drain flow exceeds the OEM limit, oil temperature rises faster than normal, and metal particles appear in the hydraulic oil.   Q: Should I replace the valve plate when fitting the new 206-60-X1261 pump?A: This 206-60-X1261 assembly includes a new matched valve plate and rotating group, so the sealing interface is correct from installation. No additional valve plate replacement is required.   Q: Does the 206-60-X1261 pump fit other Komatsu models besides the PC220-5?A: Cross-reference numbers 206-60-X1261 / 708-25-04061 / 708-25-04022 / 708-25-04021 apply. The 206-60-X1261 pump is dimensionally matched to the HPV90 pump application; confirm your machine serial number with our team if you are unsure of compatibility.   Q: How to confirm the 206-60-X1261 is the correct pump for my PC220-5?A: Match the pump model plate reading 206-60-X1261 and confirm the machine model is PC220-5. Provide the pump and machine serial numbers to our team for exact cross-reference confirmation.   Q: What quality options are available?A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.   Q:Why Choose RITO?A:Listed FactoryStable&Reliable QualityOEM Factory for Chinese Top Excavator BrandsSupplier to Fortune 500 Companies
