Maintenance Procedures
13. Slide Base 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 when
driving the vehicle. (ILS slider plungers do
not require adjustment.) To obtain proper
adjustment, perform the following
procedures.
1. Loosen lock nut and turn adjustment
bolt out (counterclockwise)
(Figure 36).
2. Disengage and engage locking
plungers. Verify that plungers have
engaged properly, as shown (Figures
37 and 38).
3. Tighten adjustment bolt until it
contacts the rack.
4. Turn adjustment bolt clockwise an
additional 1/2 turn, then tighten lock
nut securely.
If plungers do not release fully to allow fifth
wheel to slide:
a. Check the air cylinder for proper
operation. Replace if necessary.
b. Check plunger adjustment as
explained above.
c. If a plunger is binding in the plunger
pocket, remove the plunger using a
Holland F-TLN-2500 spring
compressor. Grind the top edges of
the plunger 1/16”, as shown
(Figure 39). Re-install and adjust
the plungers as explained above.
