ATI is pleased to announce the release of our billet-machined, aluminum Vacuum Pump Pulley (PN 916199). This pulley was engineered for Chris Rini's ATI sponsored, Sonnys-Hemi-powered Top Sportsman car. The extra wide, 20mm (3/4"), pulley solved the belt failure problem associated with the narrow 10MM-1/2" belt. The pulley is CNC machined with a 40 tooth HTD, 8mm pitch belt fully shaped to the proper contour. The center hole is machined for a 1/2" shaft with a three bolt mounting system. The Pulley fits Moroso vacuum pumps # 22640, 22641, 22642, and 22643
