16. Slide Base Adjustment
(Traditional Sliders Only -
discontinued)
NOTE:
ILS slider and Severe-Duty slider
locking plungers DO NOT require
adjustment.
Some HOLLAND slide bases are equipped with
adjustable locking plungers. Adjustment should
be performed at a minimum of every 60,000
miles or if excessive movement is noticed while
driving the vehicle. To obtain proper adjustment,
follow these procedures:
1. Loosen
the lock nut and turn the
adjustment bolt counterclockwise
(Figure 51)
.
2. Disengage and engage the locking
plungers. Verify that the locking
plungers have engaged properly
(Figures 52 and 53)
.
3. Tighten
the adjustment bolt until it
contacts the rack.
4. Turn
the adjustment bolt clockwise an
additional 1/2 turn, then tighten the
lock nut securely.
If the locking plungers DO NOT release fully
to allow the fifth wheel to slide:
Check the air cylinder for proper
operation. Replace if necessary.
Check
the locking plunger adjustment
as explained above.
If a locking plunger is binding in the
plunger pocket, remove the locking
plunger using a HOLLAND TF-TLN-2500
spring compressor. Grind the top edges
of the locking plunger 1/16" (1.5 mm)
(Figure 54)
. Re-install and adjust the
locking plungers as explained above.
