FIFTH WHEEL INSPECTIONS:

1. Inspect the fifth wheel and mounting.

• Confirm that the lube

plate inserts are in place

and firmly attached.

•Tighten loose fasteners.

• Replace missing

fasteners.

• Repair/replace missing, cracked or

otherwise damaged components.

If you have a sliding fifth wheel, make sure both

plungers are fully engaged (see page 4, Figure 4b).

2. Make sure the locks are open. To open locks,

pull release handle.

If Air Release equipped, set tractor brakes and actuate

the fifth wheel control valve to open the locks.

3. Inspect the lock jaws. If

they appear dry, apply

grease to lock jaws and

front of throat directly or

through the lube tube

grease fitting. Coupled

lock jaws and front of

throat can

be lubricated

through lube tube grease

fitting (see Holland

publication XL-FW309-XX

Maintenance Procedures).

4. Tilt the

ramps down.

TRAILER UPPER COUPLER INSPECTIONS:

1. Inspect the leading edge of the

trailer bolster/skid plate. It must be

free of any square or sharp edges.

2. Make sure that there are no bolts

or nuts extending below the

bolster/skid plate

within 8˝ of the

fifth wheel travel

path while coupling.

3. The area that is

supported by the

fifth wheel should

be free of any large

holes or gouges.

4. Any access holes that the

fifth wheel passes below

should have chamfered

and radius edges.

5. Check that any splits from

the skid plate to bolster

plate are welded

adequately and that there are

no sharp edges or abrupt

changes in elevation.

6. The upper coupler should

extend adequately rearward

to maintain full contact with

the fifth wheel during tight

turning. If it does not, at a

minimum, the rear edges

should be chamfered

and radiused.

7. Make sure that any upper

coupler residual grease is free

of heavy coarse grit.

8. Ensure that the upper coupler fifth wheel contact

surface is free of rust. Do not paint contact area!

The area can be conditioned with rust inhibitor.

9. Inspect the kingpin for excessive wear and

damage (use Holland tool TF-0110 “Kingpin

Gage”) along with bolster bow (see SAE J700).
