Why Choose the SPARKLING 11709730 Gear Pump?

• • • • • • • • • • • • • • • • • • • • • • • • • • • • • • •    - High Volumetric Efficiency: Precision-machined gears and pressure-balanced wear plates minimize internal leakage, ensuring maximum flow to the steering or pilot systems.

                                                            •    - Compact & Durable: Designed to fit within the tight engine compartments of the BL70/71, resisting the heat and vibration common in backhoe operations.

                                                            •    - Low Noise Operation: Optimized gear tooth profiles reduce "whine" and cavitation noise, improving operator comfort.

                                                            •    - Direct OEM Fit: Manufactured to the exact 11709730 specifications for easy installation and immediate system compatibility.

Q&A Section

Q1: What are the signs that my 11709730 pump is failing?

A: The most common symptoms are sluggish or "heavy" steering, slow response from the backhoe pilot controls, or a loud whining noise coming from the pump area when the oil is hot. If the pump is badly worn, you may also see excessive heat in the hydraulic tank.

Q2: Should I replace the hydraulic filters when installing this pump?

A: Absolutely. If the old pump failed due to wear, metallic particles may be trapped in the system. Installing a new 11709730 pump without changing the filters and flushing the lines can lead to the new pump being destroyed within hours.

Q3: Can this pump be repaired with a seal kit?

A: If the pump is only leaking oil from the shaft or housing, a seal kit may work. However, if the machine is losing hydraulic power (internal bypass), the internal gears and housing are likely scored, and a full pump replacement is required.
