Top Plate Replacement Rebuild Kit
SAF-Holland

Top plate replacement rebuild kit provides a focused refurbishment path for the upper interface of the fifth wheel assembly. The kit specifies a height of 2.88 inches, aligning with standard top plate geometry to restore accurate engagement with the lower plate and locking mechanism. It is categorized under 42763 and linked to the Fifth Wheel family with VMRS code 059-001-045, reflecting its role in top plate renewal. Benefits include regaining precise centering, tightening tolerances, and improving lock engagement under load, which translates into safer and more predictable coupling. The rebuild approach minimizes downtime and avoids full assembly replacement in routine maintenance or after moderate wear. The solution is compatible with conventional frame mounting patterns used on heavy duty tractors and trailers. Cross references are not provided; verify exact top plate dimensions and hole patterns to ensure proper fit during installation.
