Section 13 - Fifth Wheel Adjustment - Holland FWS1 Series Owner's Manual

13. Fifth Wheel Adjustment
Fifth wheel adjustment should be checked
at a minimum of every 60,000 miles or if
excessive movement between kingpin and
fifth wheel is noticed when driving the vehicle.
IMPORTANT: Excessive movement
between the tractor
and trailer can effect
vehicle handling.
Failure to maintain proper
fifth wheel adjustment
could result in loss of
vehicle control which, if
not avoided, could result
in death or serious injury.
NOTE: To obtain proper fifth wheel
adjustment SAF-HOLLAND
recommends use of HOLLAND
lock tester Part No. 4000171,
available from your local
HOLLAND distributor.
1. If fifth wheel is locked, lift release
handle up, pull all the way out, and up
again to hook on casting. If air release
equipped, actuate fifth wheel control
valve to open lock (Figure 26).
2. Ram lock tester into fifth wheel top
plate to lock fifth wheel (Figure 27).
3. Push the lock tester forward so that it
is tight against the fifth wheel's front
lock. Ensure the lock tester is pressed
flat against the surface of the fifth
wheel. Scribe a line on the surface of
the fifth wheel face along front edge
of lock tester (Figure 28).
4. Pull lock tester toward fifth wheel ramps.
Ensure the lock tester is pressed flat
