The PAI HSA-4934-BEN is a Bendix Benchmark slack adjuster with a 1-1/2-inch spline diameter, 28 spline teeth, and a 26,000 lb SAE torque rating. Slack adjusters are heavy duty diesel truck parts that convert brake chamber movement into rotation at the brake mechanism, applying the mechanical leverage used for air-brake actuation. The spline dimensions and SAE torque rating define this component's configuration for accurate brake-system matching. BENCHMARK TECHNOLOGY GROUP lists 286965 as the OEM reference; MACK cross-references include 5396-KN44051 and 745-286965.
