Product Introduction

This pressure plate is a critical component for engaging the high/low range gear ratio, engineered to handle high axial forces during shifting.

• Structure & Material: Precision-machined from high-strength alloy steel, with an annular design, a central bore for shaft clearance, and a locating hole for precise assembly.

• Strength & Durability: The hardened steel construction resists deformation and wear under high pressure, ensuring consistent performance over long service life.

• Precision Fit: Machined to tight dimensional tolerances, it aligns perfectly with the range sleeve and pressure plate pad, ensuring smooth and reliable range shifts.

Core Function

1. Range Shift Actuation: Transmits axial force from the range cylinder to the range sleeve, engaging the planetary gear set to switch between high and low gear ratios.

2. Force Distribution: Distributes actuation pressure evenly across the range sleeve, preventing localized wear and ensuring stable engagement.

3. Precision Alignment: Maintains the correct position of the range sleeve, ensuring accurate gear ratio switching and reducing transmission noise.

Customer Case Study – WG2229100072 Pressure Plate in Action

In early 2024, a fleet maintenance company based in Lagos, Nigeria reached out to Mettlead with an urgent requirement. They were managing a fleet of 45 SINOTRUK HOWO A7 dump trucks used in quarry operations, and gearbox failures were eating into their productivity. After detailed technical consultation, our team identified worn pressure plates as the root cause of their recurring clutch slippage issues.

We supplied 60 units of the Pressure Plate WG2229100072 for their SINOTRUK HW series gearboxes — enough for immediate replacements plus strategic spares. The entire order was shipped within 7 working days via sea freight to Lagos port. Following installation, the client reported a 40% reduction in unplanned gearbox downtime over the subsequent three months. Moreover, they noted that gear engagement quality improved noticeably compared to the locally sourced alternatives they had previously used.

Today, this client maintains a standing quarterly order for the WG2229100072 pressure plate along with other SINOTRUK HW gearbox wear parts, consolidating their sourcing through Mettlead for consistency and cost efficiency.

Frequently Asked Questions – Pressure Plate WG2229100072

What trucks and gearboxes does the WG2229100072 pressure plate fit?

The WG2229100072 pressure plate is specifically designed for SINOTRUK HW series gearboxes, including models like HW15710, HW19710, and HW19712.
