Detailed Description

Gates EG2 is an alternator coupler for Volvo charging system service, engineered around the EuroGrip flexible coupler design. The coupler supports accessory drive operation by reducing stress caused by rigid coupling in systems where shaft alignment can change during engine movement. Its OE Exact rating and listed dimensions make it a precise replacement choice for Volvo S60, V60, XC60, S80, XC70, XC90, and V70 applications.

This part cross-references Interchanges 30750111 for the same application. Use Gates EG2 when servicing the alternator coupler on 2007-2016 Volvo platforms that require the specified curvilinear profile and 18-tooth configuration.

What It Helps Address

• Alternator drive vibration and noise from a worn coupler
