XL2 SLIDE-OUT SERVICE MANUAL
5.7 GUIDE WHEEL
A plastic wheel is mounted on one of the lower
shaft pinion on each slide-out. This wheel is
used to guide the slide-out when extending or
retracting. The wheel follows a track between
the rack and the slide-out. To replace this wheel,
remove the pinion from the shaft and unscrew
the guide wheel screws from the pinion (refer to
section 5.4 and 5.5).
5.8 PLASTIC STOPPER
There is a UHMW plastic stopper used to block
any axial movement of the front slide-out lower
shaft (figure 26). This stopper must be adjusted
1/32" away from the pinion.
6. ELECTRIC MOTOR
The power is supplied by a 1/3 HP electric motor
coupled with a speed reduction gearbox.
6.1 MAINTENANCE
Inspect the electrical connections and their
watertightness. Check that the bolts and the
holding metal strap are tight (figure 23).
6.2 REPLACEMENT
1. The slide-out must be retracted and all the
pins locked.
2. Disconnect the electric wire cable from the
motor. Release the motor holding metal
strap (figure 23).
3. Remove the motor from the gearbox.
4. Fasten the new motor to the gearbox using
screws.

7. SPEED REDUCTION
GEARBOX
The speed reduction gearbox used is a helical
worm gear type. This gearbox has a 140:1 ratio
and the output shaft is self-locking. See section
18.3 for gearbox specifications.
7.1 MAINTENANCE
Inspect the gearbox to check if there is any
leakage or backlash in the box or between the
keys and their keyseat. Replace the gearbox if
excessive wear is present. Check that all bolts
are tight.
Check the oil level. The gearbox is lubricated for
life and the oil should not have to be changed.
Check the gearbox axle alignment with the right
angle drive and adjust it if necessary (section 8).
7.2 GEARBOX REPLACEMENT
1. The slide-out must be retracted and all the
pins locked.
2. Disengage the lower jaw coupling, and for
the front slide-out, remove the universal joint
from the right angle drive shaft (figure 1).
3.
For the front slide-out: Remove the
reinforcement plate from the gearbox (figure
24).
4. Remove the motor from the gearbox (see
section 6.2).
