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 adjustment
SAF-HOLLAND recommends use
of Holland lock tester Part No.
TF-TLN-5001, available from
your local Holland distributor.
1.
Back off adjustment nut several turns
(Figure 38).
2.
If fifth wheel is locked, pull release handle
to unlock fifth wheel. If equipped with a
manual secondary lock, first pull secondary
release handle and hook on casting.
3.
Set lock tester on fifth wheel top plate
(Figure 36).
4.
To lock fifth wheel, rotate lock tester
handle clockwise (Figure 37).
5.
With locks closed around lock tester,
position adjustment nut on yoke shaft
so it is slightly compressing rubber
washer making it difficult to turn by
hand (Figure 38).
6.
Turn adjustment nut one additional
full turn clockwise to further compress
rubber washer (Figure 38).
IMPORTANT: Over compressing the
bushing with additional
turns will take the fifth
wheel out of proper
adjustment and degrade
the performance of the
fifth wheel.
