★ Timken tapered roller bearings are the industry standard for military vehicles — durable, heat-resistant and designed for the demanding conditions of WWII and post-war military service.
Application
This bearing is used for the rear differential pinion on post-war Dodge military vehicles. The designation 'late pinion' refers to later production variants of the Dodge WC series and civilian Dodge lorries with similar rear axle configurations from the 1940s-'50s.
Installation notes
Replacement of pinion bearings requires complete disassembly of the differential. Pinion preload must be accurately adjusted with shims — incorrect preload leads to rapid wear and noise. Use an inch-pound torque wrench to check bearing preload. Always replace both pinion bearings (inner and outer) simultaneously, together with pinion seal and crush sleeve. Check tooth pattern with marking compound after assembly.
Compatibility
Note: pinion bearings depend on the specific differential type (8¾" vs 9⅝" ring gear). Always verify original bearing numbers before replacement. Not compatible with early WC series differential configurations using different bearing specifications.
Historical context
Timken tapered roller bearings were original equipment on Dodge military vehicles during and after WWII. The 59187-59412 specification was used in later production rear axle assemblies.
