Service fifth wheel, pivot pins, bushings, locking mechanisms, and mounting hardware.


Servicing should include inspecting and making necessary adjustments. Fifth wheel jaws periodically need adjusting to take the slack out between the pin and fifth wheel. The fifth wheel needs to be kept lubricated so the trailer will not bind metal against metal, which could impair turning and push the tractor in a straight line.

Process/Skill Questions

  • How often should the fifth wheel connection be checked?
  • Can the mounting bolts be checked with a hammer to determine if the bolts connecting the fifth wheel plate to the tractor frame? Explain.
