Product Introduction

• Structure: A gear-type hydraulic pump constructed from high-strength aluminum alloy, featuring a helical gear drive, an integrated pressure relief valve, and sealed fluid ports. The pump is directly driven by the engine’s accessory drive system for reliable power transfer.

• Performance: Delivers a stable flow of hydraulic fluid at pressures up to 140 bar, ensuring consistent steering assist even under heavy loads or at low speeds. The helical gear design ensures quiet, low-vibration operation, while the aluminum housing provides efficient heat dissipation and corrosion resistance.

Core Function

1. Hydraulic Pressure Generation: Produces the high-pressure fluid needed to actuate the steering gear box, reducing the driver’s steering effort by up to 70%.

2. System Safety: The integrated pressure relief valve protects the steering system from overpressure damage, maintaining safe and reliable operation.

3. Quiet & Smooth Operation: The helical gear drive minimizes noise and vibration, improving driver comfort during long-haul operation.

Frequently Asked Questions – WG9619470080 Power Steering Pump

Is this power steering pump an original Sinotruk part or aftermarket?

The WG9619470080 pump we supply is manufactured to OEM-equivalent specifications. It matches the original part in dimensions, performance output, and fitment. While it is produced in our partner factory rather than the original Sinotruk assembly line, it undergoes the same strict quality control testing to ensure identical reliability and service life.

How can I verify that WG9619470080 fits my specific HOWO truck model?

The most reliable method is to check the part number stamped on your existing steering pump. If it reads WG9619470080, our replacement is a direct fit. Alternatively, you can provide us with your truck’s VIN or chassis number, and our technical team will confirm compatibility before you place your order.

What causes a power steering pump to fail prematurely?

Several factors shorten the lifespan of a hydraulic steering pump. Contaminated or degraded steering fluid is the most common culprit — it accelerates internal wear on the vanes and bearings. Low fluid levels cause cavitation, which damages the pump rapidly. Additionally, a worn or misaligned drive belt creates excessive load on the pump shaft seal, leading to leaks and eventual failure.

Should I replace the steering fluid when installing a new WG9619470080 pump?

Absolutely. We strongly recommend flushing the entire power steering system and refilling with fresh, manufacturer-approved hydraulic fluid when installing a new pump. Old fluid may contain metal particles and contaminants from the failed pump, and these will immediately damage your new unit if left in the system.

What is the typical lead time for bulk orders of this steering pump?

For standard stock quantities, we ship within 3–7 business days after payment confirmation. Larger bulk orders or custom-packaged shipments typically require 10–15 business days for production and quality inspection. Our logistics team provides tracking updates throughout the process so you always know where your parts are.

Can I order a sample unit before committing to a bulk purchase?

Yes, we welcome sample orders. Many procurement managers prefer to test fitment and quality before placing large volume orders, and we fully support this approach. Simply reach out to our sales team with your sample request, and we’ll arrange priority shipment.
