Warning: All fifth wheel maintenance, adjustment, and rebuilding must be done only by a qualified mechanic. Improper or incomplete procedures could result in a possible disengagement of the trailer from the tractor, which could result in personal injury or property damage.

Parts are under spring compression. Wear safety goggles while servicing the fifth wheel. Failure to do so can result in personal injury, due to parts ejecting with force.

  1. Thoroughly steam clean all fifth wheel components before inspection.
  2. Check for cracks in the fifth wheel assembly, mounting brackets, and mounting parts.
  3. Check the fastener torques on the fifth wheel assembly and fifth wheel mounting. Tighten bolts and nuts as needed. Replace missing or damaged bolts.
  4. Inspect the fifth wheel for bent, worn, damaged, and missing parts; replace them as needed with genuine Holland parts.
  5. Using a Holland Kingpin Lock Tester (Holland tool number TF-TLN-5001, available through the PDCs as HLD TFTLN5001), check the operation of the locking mechanism by opening and closing the locks. See Fig..
  6. After inspecting the fifth wheel, lubricate all moving parts with a chassis or multipurpose grease. See General Description for lubrication instructions.

    • The nut and washer should be snug against the fifth wheel.

    • The locks should be completely closed around the kingpin.
