Hydraulic Timing Chain Tensioner – Installation Guide

Part No.: K22722
For Yamaha SR400 / SR500 / TT500 / XT500

Installation Procedure

1 Remove the complete OEM chain tensioner.

2 Install the hydraulic tensioner in the same position as the OEM unit. The adjustment is similar: the center bolt must align precisely with the housing.

3 Note: As the tensioner touches the guide rail, turning the bolt becomes stiffer due to damping — this is normal.

4 If installing with a new tensioner rail, the hydraulic tensioner must be compressed before mounting (thread length is longer).

5 Warm the tensioner with a hairdryer to approx. 40 °C / 104 °F to thin the oil and make installation easier.

6 The center bolt may recess up to 6 mm / 0.24″ into the housing without affecting function.

7 Tighten the locknut to 40 Nm.
