Camshaft Overhaul Kit
Bendix

Designed to restore peak performance in camshaft assemblies within heavy‑duty air brake systems, this refurbishment package assembles a complete set of wear parts that experience the greatest service life challenges. The collection replaces two spider bushing assemblies, four spider seals, two cam support housings, two camshaft washers, two anchor pin washers, two camshaft lock rings, two additional camshaft washers, two camshaft lock rings, and eight self‑tapping screws. When installed together, these components renew timing surfaces, align rotating elements, and reestablish proper seating of moving parts to sustain accurate valve actuation across temperature and load changes. The combination reduces end play, maintains tighter tolerances, and preserves reliable torque transfer throughout the camshaft path. By addressing wear at multiple contact points—bushings, seals, spacers, and retaining rings—the kit helps extend service intervals, lowers the risk of camshaft galling, and minimizes unplanned downtime due to premature wear. VMRS code 013-012-013 places the work in the camshaft maintenance category, while the category context indicates a Bendix camshaft overhaul application. This kit is well suited for repair shops or fleet service crews performing in‑field refreshes of critical camshaft components without sacrificing reliability or performance.
