ABSTRACT:
A device, for use with a pulley having a substantially cylindrical outer surface with a first circumferential belt groove therein defining a first pitch diameter, for increasing the pitch diameter to a desired second pitch diameter. The device includes a pulley rim having a substantially cylindrical inner surface configured to be received around the pulley and a substantially cylindrical outer surface having a second circumferential belt groove therein defining the desired second pitch diameter. The pulley rim is releasably clamped concentrically around the pulley by coaction with the first groove to mount same thereon thereby increasing the pitch diameter of the pulley to the second pitch diameter.
