## What Is a Spline Driveshaft Holder?
The **Yamaha Spline Driveshaft Holder 80-400-10** is a specialised tool used to hold a compatible driveshaft securely during maintenance.
A personal watercraft driveshaft transfers rotational power through the driveline to the jet pump assembly.
During certain maintenance procedures, it may be necessary to prevent the driveshaft from rotating while another component is loosened or tightened.
A spline driveshaft holder engages the appropriate splined connection, allowing the technician to hold the shaft in position.
Using the correct tool helps reduce the risk of damaging the driveshaft or associated components through improper holding methods.
## Why Use a Driveshaft Holding Tool?
Jet pump and driveline maintenance can involve components that are tightly secured or difficult to remove without the correct tools.
Attempting to hold a driveshaft using unsuitable equipment may damage the splines or surrounding components.
A correctly sized spline holder provides a more appropriate method of securing the shaft during applicable servicing procedures.
The **Yamaha Spline Driveshaft Holder 80-400-10** is designed for compatible Yamaha applications requiring a 16mm spline holding tool.

Always follow the relevant Yamaha service manual to determine the correct procedure and required tools.
