OTR 16.5" x 7" Unbalanced Outboard Mount Brake Drum. This outboard-mount brake drum is specified for 16.5" diameter braking systems with a 7" brake shoe width and a 9.44" pilot diameter. It addresses recurring fleet operational challenges around wheel-end serviceability and predictable wear management by matching common industry bolt patterns and drum interfaces. The unbalanced, outboard configuration is offered for applications where drum removal without hub disassembly supports faster wheel-end intervention. Precision machining of the braking surface and hub pilot dimensions promotes consistent mating to brake shoes and mounting components, helping technicians achieve repeatable assembly and measured wheel-end clearances during maintenance events. By aligning with standard bolt circle and pilot dimensions used across many commercial wheel-end designs, this drum supports streamlined stocking and interchangeability within mixed fleets, which can simplify parts logistics and reduce the number of unique SKUs kept in inventory. The drums braking surface geometry and thermal mass characteristics correspond with typical heavy-duty service demands and standard inspection intervals; these attributes contribute to predictable wear profiles and measured service life when maintained to recommended inspection practices. Published manufacturer specifications and aftermarket cross-reference listings identify bolt hole counts, bolt circle diameters, and maximum wear diameters to facilitate accurate replacement decisions and documented maintenance records. For fleets tracking mean time to repair (MTTR) and inventory turns, this drum is positioned to support repeatable, auditable wheel-end service procedures and standardized parts management across vocational, highway, and trailer applications where 16.5"x7" outboard drums are specified.
