MIL-DTL-11891G, DETAIL SPECIFICATION: TRACK SHOE SETS, TRACK SHOE ASSEMBLIES, TRACK SHOE PADS AND TRACK SHOE BUSHINGS, VEHICULAR: ELASTOMERIZED (25 FEB 1998) [SUPERSEDING MIL-PRF-11891F]., This specification identifies the requirements for qualification and productioncontrol of track systems supporting U.S. Military Tracked Vehicles. This specification is intendedprimarily for the qualification of elastomeric compounds used in the fabrication of track and trackcomponents and to ensure that the quality and performance established at qualification ismaintained throughout production. The contractor is held fully responsible for the entireassembly/component including all non-elastomeric components and fasteners. The qualifiedproducts list (QPL) is divided by individual track components (pads, bushings and roadwheelpath/shoe body) listing the contractors qualified to produce the various components, thecontractor抯 address, and compound identification. The QPL also identifies contractors qualifiedto assemble the various track components into full assemblies/systems. This includes bushinginsertion, 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).
