The WG9703290010 PTO Spline Shaft is a key transmission component used in heavy-duty truck power take-off (PTO) systems.
It connects the gearbox and PTO unit, transmitting engine power to auxiliary equipment such as hydraulic pumps, dump systems, and specialized vehicle attachments. It is a critical part for stable PTO operation and reliable auxiliary power output.
Core Function
- Transfers power between gearbox and PTO system
- Ensures stable torque delivery for auxiliary operations
- Prevents slippage and unstable power transmission
- Supports continuous heavy-duty working performance
Product Advantages
● High-Strength Forged Steel Construction
Made from high-strength alloy structural steel forging, the shaft features:
- Excellent strength and toughness balance
- High resistance to torque and impact loads
- Stable performance under long-term heavy-duty use
After quenching and tempering heat treatment:
- Improved hardness and fatigue resistance
- Reduced risk of deformation and fracture
- Extended service life
● Precision Machined Spline Teeth
The spline section is finely processed to ensure:
- Smooth engagement with mating components
- High surface finish and low friction
- Strict dimensional accuracy and controlled clearance
- No jamming, slipping, or abnormal wear
● Stable and Efficient Power Transmission
Designed specifically for PTO applications:
- Ensures stable torque transfer between gearbox and PTO
- Eliminates power loss and slippage issues
- Improves reliability of auxiliary system operation
- Maintains consistent performance under load
● Wear-Resistant and Long-Life Design
- High resistance to spline wear and fatigue
- No tooth breakage or deformation under heavy load
- Suitable for frequent PTO engagement cycles
