MIL-DTL-11891 Revision H:2020

This specification identifies the requirements for qualification and production control of track systems supporting U.S. Military Tracked Vehicles. This specification is intended primarily for the qualification of elastomeric compounds used in the fabrication of track and track components and to ensure that the quality and performance established at qualification is maintained throughout production. The contractor is held fully responsible for the entire assembly/component including all non-elastomeric components and fasteners. The qualified products list (QPL) is divided by individual track components (pads, bushings and roadwheel path/shoe body) listing the contractors qualified to produce the various components, the contractor’s address, and compound identification. The QPL also identifies contractors qualified to assemble the various track components into full assemblies/systems. This includes bushing insertion, pad installation and connecting component (end connectors, center guides) assembly. The track shoe assemblies may be acquired either as sets, assemblies or as individual components (pin bushing assemblies or pads) as specified by the acquiring activity (see 6.1).
