Left-Hand Yoke, Yoke Shaft, Cam Kit XA-351/-331
SAF-Holland

Designed for heavy‑duty fifth‑wheel couplings in commercial fleets, this left‑hand assembly merges the yoke, shaft, and cam kit into a single serviceable package for the XA‑351/‑331 family. The yoke engages the locking jaw with precise movement, the shaft transmits rotation from the release lever to the cam, and the cam aligns and actuates the locking mechanism. Together, they provide reliable lock and re‑couple cycles under extreme loading and vibration. The design uses high‑strength alloy components to resist wear, maintain alignment, and extend service life between overhauls. Installation typically occurs during scheduled maintenance or after capture plate wear is detected, and the consolidated kit reduces downtime by containing all necessary components in one, factory‑validated assembly. By restoring smooth release and secure engagement, operator control improves, the risk of unintended uncoupling in transit is reduced, and coupling performance remains predictable in variable conditions.
