Bendix 17-688 or 17688 is an air brake camshaft, 1.5 in. with 10 splines, right hand, for Spicer/Eaton applications before 08-94. The camshaft carries the S-shaped cam at its head: when the brake chamber and slack adjuster turn it, the cam spreads the brake shoes outward against the drum. Spline count, hand and application are the details to match against your old shaft before you order. This is a genuine Bendix part from Pro Gear and Transmission, and we are happy to confirm fit by phone.A factory handling fee of $20.00 per unit is added at checkout.FeaturesBendix part number 17-688 or 176881.5 in., 10 spline, right hand camshaftSpicer/Eaton application, before 08-94S-cam head spreads the brake shoes against the drumGenuine Bendix partTech SpecsSize: 1.5 in.Spline count: 10Hand: Right HandApplication: Spicer/Eaton (before 08-94)
