I think that SIR tool is no longer made. Anyone know what mm size the pulley is? I have read rumors that OTC Tools 4681 puller will work. Check e-bay for them - around $50. Supposed to remove and install press-fit pulleys with a hub diameter of 1-1/8" (28mm), 1-1/4" (32mm), 1-5/16" (34mm), or 1-3/8" (35mm).
