All axial stations,31.4mm tail radius, pockets, shoulders,.2mm radial drawing allowances, shaft steps, seal section and smooth wheel/retention profiles are estimates. Nominal shaft/bearing boundary contact is illustrative, not a loaded fit. No threads, spline, seal lip, bearing races/rollers, speedometer tooth mesh, preload, endfloat, torque, actual clearance or replacement/removal path is verified.",
