ATI announces the release of its billet-machined, aluminum Vacuum Pump Pulley (PN 916199). This pulley was engineered for Chris Rini’s ATI-sponsored, Sonny’s 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.
