XL2 SLIDE-OUT SERVICE MANUAL
2. Using the slide-out control switch and/or the
manual override procedure, extend the
slide-out about one foot.
3. From outside, unscrew and remove only the
two first rack screws starting from the slide-
out panel.
4. Using the manual override procedure only,
retract the slide-out to its fully closed
position. Lock all the locking pins.
5. Loosen the pinion keyless bushing of the
rack to be changed.
6. From under the slide-out, unscrew all the
rack screws and remove the rack.
Note: The rack for the pinion and guide wheel
assembly is narrower than the other one.
7. Install a new rack between the slide out
structural rack seat and the pinion. Tighten
the screws accessible using Loctite 242 or
equivalent product.
8. Tighten the pinion keyless bushing as
described in section 5.6.
Caution: Make sure the keyless bushing is
tightened to 125 lb-ft before unlocking the pins
or moving the slide-out. Refer to section 5.6 for
torque wrench settings.
9. Using the slide-out control switch and/or the
manual override procedure, extend the
slide-out about one foot.
10. Tighten the two remaining screws using
Loctite 242 or equivalent product.
11. Using the slide-out control switch and/or the
manual override procedure, retract the slide-
out to its fully closed position. Lock all the
locking pins.
12. Re-inflate the air seal at 10 psi.
5. PINION
Caution: The front slide-out upper shaft pinions
may have to be readjusted and re-synchronized
after a load variation in the slide-out (section
5.6).
Caution: Make sure all keyless bushings are
tightened to 125 lb-ft before unlocking the pins
or moving the slide-out. Refer to section 5.6 for
torque wrench settings. A lower torque value
may cause the bushing to slip on the shaft, and
a higher torque value may break the bushing.
5.1 MAINTENANCE
Note: One of the two lower shaft pinions is
mounted with a plastic guide wheel. When
replacing this pinion, it is important to put back
the guide wheel (see section 5.7).
To tighten or loosen the keyless bushing, use
those specific tools (see section 1.1):
- crowfoot wrench 1 ½";
- torque wrench;
- combination wrench 1 ¾";
- pipe wrench;
- drive extension 5";
- socket 1 ½".
5.2 UPPER SHAFT PINION
REPLACEMENT
Note: The procedure is the same for the front
and rear slide-out, except when specified.
1. Deflate the air seal completely to prevent
any damage (see the slide-out operation
manual).
2. Use the slide-out control switch and/or the
manual override procedure to extend the
slide-out completely.
3.
For the front slide-out only: retract
manually the slide-out on 1" from its fully
extended position to release stopper
contact.
Caution: Ensure suspension stabilization before
using the height adjustable tables to prevent any
damage to the vehicle or slide-out structure.
4. Support each end of the slide-out with height
adjustable tables. Use plywood panels
covered with soft material, such a carpet, to
prevent any damage to the slide-out under
panels and the exterior panel edge (figure
7). The supporting tables should not obstruct
the slide-out bottom racks. Rise up the
tables to support the slide-out without lifting
it.
