5.7 Belt tensioner/Idle pulley

[20pilot]

I replaced the tensioner pulley this weekend. In the process the bolt that holds the pulley and also serves as the adjustment for pulley. It has a star shaped head that rotates as it is adjusted up and down. Does anyone know what the part number is for this or what it is called? tensioner pulley bolt?

Thanks

Hi replaced the pulley OEM 807757t Sierra 18-6457. The bolt that holds this has a bearing on it and while attempting to remove it I damaged it. The motor is a 5.7 on a 2005 Sea Ray. The number that is on the engine is 1A091391.

Thanks
