Power Steering Assembly DZ9114470075 for Shacman F3000 F2000 X3000 Heavy Truck Parts

The DZ9114470075 Power Steering Gear Box is a core component of the steering system for SHACMAN heavy-duty trucks, particularly models within the F2000 and F3000 series. Based on the renowned ZF 8098 technology, this unit is a domestically produced, high-reliability recirculating-ball hydraulic power steering gear widely used across China’s commercial vehicle industry.

Engineered to deliver smooth, precise, and effortless control over large-tonnage vehicles, it ensures excellent maneuverability at low speeds and stable road feedback at highway speeds. As of 2026, upgraded versions feature enhanced valve sensitivity, improved sealing materials, and higher resistance to shock loads from rough terrain — making it ideal for long-haul transport, mining, construction, and heavy-duty logistics applications.

Technical Parameters

  • Hydraulic System Requirements:

    • Recommended Fluid: 8# Hydraulic Oil or ATF Automatic Transmission Fluid

    • Operating Temperature Range: -40°C to +110°C

    • Flow Requirement: Compatible with vane-type steering pumps (e.g., ~12–16 L/min)

  • Performance Characteristics:

    • Variable Steering Ratio: Lower ratio at straight-ahead position for stability; increases during full lock for better responsiveness.

    • High Assist Multiplication: Enables easy steering even during zero-radius turns under full load.

    • Road Feel Optimization: Improved spool valve tuning enhances driver feedback at high speed without sacrificing low-speed ease.

    • Shock Load Resistance: Effectively dampens kickback from potholes, curbs, or uneven off-road surfaces.

  • Durability & Reliability:

    • Seals resistant to oil degradation and thermal aging (2026 upgrade).

    • Reinforced input/output shaft bearings for extended service life.

    • Designed for continuous operation in harsh environments (mining, quarry, desert).
