S-31110-6L or S311106L is a Hendrickson S-cam brake camshaft with 28 splines, listed as HXS, 12.25. In an air brake, the slack adjuster turns the camshaft and the S-shaped head spreads the two brake shoes outward so the linings press on the drum and slow the wheel. A worn camshaft or worn support bushings let the head wobble, which can leave the shoe lining thinner on one side. This is a genuine Hendrickson part from Pro Gear and Transmission. Call us to confirm proper fit for your brake.
