HY31 Propeller Shaft for Dump Truck PTO Systems

The HY31 Propeller Shaft is a heavy-duty drivetrain component specifically engineered for dump truck power take-off (PTO) systems, designed to reliably transmit torque for hydraulic dump operations under heavy-load and dynamic working conditions.

Crafted from high-strength alloy steel and finished with a durable black anti-corrosion coating, this propeller shaft delivers exceptional torsional rigidity and impact resistance, ensuring stable performance during frequent dump operations and extending service life.

It integrates three core precision components to guarantee efficient power delivery:

A Flange Yoke with 50×62×9 dimensions and 55mm recess, featuring a 4-hole flange interface that forms a secure, rigid connection to the PTO system, ensuring consistent power transfer under heavy hydraulic loads.

An 8-spline x 35 splined yoke, designed to directly engage with the hydraulic pump input shaft, providing a reliable, slip-free power transmission interface that withstands the high torque demands of dump operations.

A 30×88 Universal Joint (Cardan Joint), a heavy-duty cross joint that accommodates angular misalignment between the PTO and hydraulic pump, enabling smooth and continuous power delivery even under the vehicle’s dynamic operating conditions. Its sealed bearing structure with precision-machined caps prevents dust and moisture ingress, reducing maintenance frequency and enhancing durability.

Manufactured with strict dimensional tolerances, the HY31 ensures excellent dynamic balance, minimizing vibration and noise to enhance operational stability and protect surrounding drivetrain components. The anti-corrosion black coating provides reliable protection against rust, road salt, and abrasive environmental factors, making it suitable for long-term use in diverse weather and terrain conditions.

This propeller shaft is ideally suited for dump trucks and other heavy-duty vehicles, where reliable PTO power transmission, durability, and resistance to harsh operating conditions are critical operational requirements. It is engineered to match original equipment specifications for seamless installation and optimal performance, serving as a reliable replacement component for fleet maintenance and repair.
