1. With the piston shaft in the exposed
position, clean with penetrating oil and
a clean shop towel
(Figure 46)

four (2-4) drops of air tool oil to the cylinder
through the supply fitting. Re-install the
supply air line
(Figure 47).
3. Activate and de-activate the air cylinder
two to three (2-3) times to work the air
tool oil into the cylinder and onto the
piston and verify proper operation.
15. Fifth Wheel Adjustment
Fifth wheel adjustments should be
performed at a minimum of every 60,000
miles or if excessive movement between
the kingpin and fifth wheel is noticed while
driving the vehicle.
IMPORTANT:
Excessive movement
between the tractor
and trailer can affect
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 the use of
