US 10,495,194 B2 · Adjustable bracket to adjust front end accessory drive for use with stretch fit belt

Abstract

The disclosed inventive concept provides an adjustable and lockable bracket assembly that allows a stretch fit belt to be installed loosely on the pulleys of an accessory drive system. The assembly includes a fixed bracket attached to the engine, a pivoting and lockable bracket attached to the fixed bracket and an adjustable driven unit, an adjustable arm for moving the adjustable driven unit between a “belt install” position allowing attachment of the belt and a “final” position for stretching the attached belt, and a rotatable insert having an offset threaded hole with a threaded fastener attached to the adjustable arm for moving the driven unit between the “belt install” and “final” positions. In the “belt install” position, the stretch fit belt may be fitted over the FEAD pulleys. Once in position, the rotatable insert is rotated to move the driven unit to the “final” position again via the adjustable arm.
