Gates 39476 Accessory Drive Belt Tensioner Assembly

Gates DriveAlign OE Belt Tensioner

The Gates DriveAlign Premium OE Automatic Belt Tensioner, part number 39476, is built for accessory drive belt systems that require stable belt control and OE-style fit.

Installation Notes

Verify pulley style, belt type, and mounting points against the original tensioner before installation.

Inspect the accessory belt and related pulleys during service so the new tensioner is installed into a clean, properly aligned drive system.
