Unloader Kit
Bendix

The unloader kit assembles essential reconditioning components for the unload function of a single or multi-cylinder air brake compressor. Contents include piston ring sets, piston and wrist pin kits, a steel connecting rod, and connecting rod insert kits, all chosen to restore proper valve timing, reduce internal leakage, and promote efficient unloading during start and shutdown cycles. By restoring precise movement and sealing of the unloading mechanism, this kit helps minimize compressor overheating, reduces cycling load on the prime mover, and preserves overall system efficiency. The kit aligns with Bendix maintenance and overhaul practices, supporting straightforward field or workshop replacement to extend compressor life and maintain peak performance in demanding duty cycles. The VMRS code 013-009-038 anchors the rebuild within a structured maintenance framework, while the category 42848 designation confirms the part’s place in the air system components used to manage compressor unloading. In installations requiring compatibility checks, cross references are not listed, but standard overhaul procedures and OEM data provide clear guidance for integrating these components into existing assemblies.
