Abstract: A tensioner comprising a base having a shaft and having a radially projecting tab therefrom, a pivot arm pivotally engaged with the shaft about a pivot axis A-A, a torsion spring disposed between the base and the pivot arm, the torsion spring in a compressed state, a pulley journalled to the pivot arm, a first axial member extending from the pivot arm, the first axial member comprising a radially projecting portion adjacent to a radially receding portion, and the radially projecting portion engaging the radially projecting tab in a first pivot arm position and the radially receding portion cooperating with the radially projecting tab in a second pivot arm position.

Abstract: A tensioner comprising a base, a shaft extending from the base, a pivot arm pivotally engaged with the shaft, a torsion spring disposed between the pivot arm the base, a base portion cooperatively engagable with a pivot arm portion upon an axial movement of the pivot arm to a first position, a removable member engaged with the shaft to retain the pivot arm in the first position, the first position limiting the pivot arm to a first range of movement, and the pivot arm axially moveable to a second position upon removal of the removable member, the second position limiting the pivot arm to a second range of movement.
