The WG9703290001 PTO Spline Shaft is a key transmission component used in heavy-duty truck power take-off (PTO) systems.

It is responsible for transmitting power between the gearbox and the PTO unit, ensuring stable and efficient torque delivery during vehicle auxiliary operations such as hydraulic pumps, dump systems, and special-purpose equipment.

This component is essential for reliable PTO performance and stable power output.

Core Function

• Transfers power between transmission and PTO system
• Ensures stable torque output for auxiliary operations
• Prevents power loss, slippage, and unstable engagement
• Supports heavy-duty working conditions and continuous operation

Product Advantages

● High-Strength Forged Alloy Steel

Made from high-strength alloy structural steel forging, the shaft features:

• High rigidity and excellent toughness
• Strong resistance to torque and impact loads
• Stable performance under long-term heavy-duty use

After quenching and tempering heat treatment:

• Balanced hardness and toughness
• Improved fatigue resistance
• Long service life under continuous operation

● Precision Machined Spline Section

The spline section is finely processed to ensure:

• High surface finish and smooth engagement
• Accurate dimensional control
• Uniform clearance with mating parts
• No jamming or slipping during operation

This ensures reliable torque transmission at all times.

● Stable Power Transmission Performance

Designed for PTO working conditions:

• Eliminates power slip between gearbox and PTO
• Ensures stable and continuous torque output
• Improves efficiency of auxiliary equipment operation
• Reduces vibration and mechanical loss

● High Durability & Wear Resistance
