This genuine Volvo Penta needle roller is a precision needle roller used in the specified selector, valve or bearing mechanism used in the HS1A reverse-gear selector and control-valve mechanism.

In service, it provides the rolling contact element for the selector or valve mechanism, reducing friction and preserving accurate control movement.

🛠️ Service Notes

• Supplied as a single loose roller rather than a caged set — count out the correct quantity for the selector/valve bore rather than assuming a full cage's worth
• Used in the HS1A reverse-gear selector and control-valve mechanism rather than a shaft bearing position, so check the valve bore and pin for wear as well as the roller itself
