Bent kingpin, damaged upper

4.
Slide the primary release handle forward,
pull the handle out, then slide it forward
again and hook it on the notch of the
top plate casting (

Replace release handle using proper
release handle replacement kit for your

Holland for additional information.
6.
Check the kingpin and upper plate
coupler as detailed in Holland Service
Bulletin XL-SB20. Remove any improperly
installed or improperly specified lube
plates. Refer to Holland Service Bulletin

Slowly back the tractor up to the
trailer. Pick up the trailer with the fifth
wheel. Stop. Then continue backing up
until the fifth wheel locks firmly to the
kingpin. Stopping helps prevent hitting
the kingpin too hard.
