another wrench to tighten the black part. Figure
20 shows how to tighten the keyless bushing.
When tightening, make sure the pinion does not
move or rotate.

TORQUE WRENCH FORMULA
Caution: Make sure all keyless bushings are
tightened to 125 lb-ft before unlocking the pins
or moving the slide-out. A lower torque value
may cause the bushing to slip on the shaft, and
a higher torque value may break the bushing.
The torque may need to be recalculated
depending of the wrench size. Refer to figure 21
for wrench size compensation.
REAR SLIDE-OUT PINIONS
To adjust and synchronize the rear slide-out
pinions, tighten the keyless bushing to 125 lb-ft
(refer to figure 21 for wrench size compensation)
after having centered the pinion in its rack. Take
note that when the keyless bushing nut is
tightened, the pinion moves about 1/16" to 3/32"
toward the slide-out center.
FRONT SLIDE-OUT PINIONS
A torque must be applied on the upper shaft to
compensate the effect of the center of gravity of
the slide-out when inside the vehicle. This
gravity effect causes the slide-out to fall down
inside the vehicle. The torque applied on the
shaft forces the pinions to push the upper part of
the slide-out outside the vehicle to
counterbalance the gravity effect.
Note: The driver side keyless bushing located
on the lower shaft is not accessible when the
slide-out is installed. Therefore, it must be
tightened before installing the slide-out.
Follow these steps to adjust and synchronize the
front slide-out pinions.
1. The slide-out must be retracted and all the
pins locked.
2. Make sure the adjustable shaft assembly is
tightened (refer to figure 22).
3. On the driver side, tighten the upper shaft
keyless bushing to 125 lb-ft (refer to figure
21 for wrench size compensation). Make
sure the pinion is centered and fits well in its
rack to eliminate any possible backlash.
Take note that when the keyless bushing nut
is tightened, the pinion moves about 1/16" to
3/32" toward the slide-out center.

4. Tighten the other side keyless bushing to
125 lb-ft by using the same procedure
described in the previous step.
5. On the lower shaft, tighten the left-hand side
keyless bushing to 125 lb-ft (refer to figure
21 for wrench size compensation).
6. Once all the keyless bushings are tightened,
unplug the air tubing from the locking pins
air valve to prevent movement of the slide-
out during the verification of the pinion
synchronization.
7. Operate the slide-out and check if the
exterior panels of the slide-out are parallel
with the vehicle panels. If not, rotate the
upper part of the adjustable shaft assembly
as required to obtain proper alignment (refer
to figure 22).
Caution: Make sure the adjustable shaft bolts
are tightened to 25 lb-ft. This insures that the
adjustable shaft assembly is properly locked.
