mechanism, inspect and adjust it as follows.
9.1 Check the bracket for any cracks or
missing and damaged parts.
9.2 Inspect the locking plungers for full
engagement.
9.3 Check the locking mechanism for proper
operation.
If the plungers will not release, check the
air cylinder or plunger adjustment.
If the plungers are loose, check the
plunger adjustment and the plunger
springs for proper compression. Replace
if needed.
9.4 The outboard slider assembly requires no
adjustment. If the plungers are loose,
inspect and replace locking mechanism
parts as needed.
9.5 The inboard slider is adjustable for frame
width and plunger engagement. For
adjustment, refer to the fifth wheel
installation instructions.
10. Replace cracked, worn, or damaged parts with
new parts. Replace all loose mounting bolts with
5/8–11 SAE grade 8 bolts, grade C locknuts, and
hardened washers. Do not re-use bolts, nuts,
and washers on fifth wheel mountings.
11. After inspecting the fifth wheel, lubricate all
moving parts with a chassis or multipurpose
grease. Apply a generous coating of grease to
the top plate to fill the grooves, or depressions,
on the top plate. See
