Maintenance Procedures
12. 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, follow the following
procedures.
1. Loosen lock nut and turn adjustment
bolt out (counterclockwise)
(Figure 26).
2. Disengage and engage locking
plungers. Verify that plungers have
engaged properly, as shown (Figures
27 and 28).
3. Tighten adjustment bolt until it con-
tacts 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 com-
pressor. Grind the top edges of the
plunger 1/16”, as shown (Figure
29). Re-install and adjust the plun-
gers as explained above.
