XA-1706-1
Yoke Shaft
SAF-Holland

The yoke shaft serves as the hardware axis for the yoke assembly, providing a stable, rotatable axis for the locking mechanism and the linked yoke components. It transmits torsional loads through the assembly while maintaining precise alignment with mating parts. The shaft's geometry is machined to tight tolerances to ensure smooth operation and predictable engagement with the corresponding cam or latch elements, contributing to reliable cycle times and consistent clamping pressure. The material and heat-treating are selected to resist fatigue under repeated lock/unlock cycles, which is critical for fleets operating in hot climates or demanding gate-to-gate schedules. VMRS code 059-001-036 identifies the function within the fifth wheel or hitch drive assembly, aiding service planning and cross-reference stocking with other 059-001-036 items, where applicable. Category 42818 groups it with related yoke and shaft assemblies for compatibility checks across SAF-Holland products. Cross references are not listed, so refer to OEM fitment guides for exact interchange compatibility. In practice, technicians should verify that the yoke shaft and shaft yoke are paired correctly to avoid binding, conduct periodic lubrication of the interface to minimize wear, and perform torque checks during maintenance to ensure safe operation during coupling.
