Repair Kit, Lower Coupler Assembly, Fifth Wheel
SAF-Holland

Maintenance-critical service kit for the lower locking subassembly of the fifth-wheel hitch. This repair set targets wear-prone components—seals, gaskets, bushings, and related hardware—providing a practical means to restore proper engagement and removal of excessive play. By refurbishing the lower locking subassembly, the operator preserves accurate centerline alignment with the kingpin, reduces latch-induced chatter, and prolongs the life of pivot and locking components. The kit is aligned with the component family category for standardization across maintenance programs and carries the VMRS identifier 059-001-032 for easy reference in service documentation and ordering systems. Fleet technicians typically deploy this kit during routine overhauls, after sustained heavy use, or when diagnosing intermittent coupling faults. Its use supports safer hitch operation, smoother decoupling, and consistent performance under load, contributing to driver confidence and trailer stability in challenging road conditions.
