7. Remove the right angle drive bracket and for
the front slide-out, remove the adjustment
plate from the speed reduction gearbox.
8. Install the right angle drive bracket on the
new gearbox without tightening the screws.
For the front slide-out, install the adjustment
plate on the speed reduction gearbox using
Loctite 242 or equivalent product.
Caution: The right angle lower vertical key must
be welded on its keyseat to prevent it from
moving or falling.
9. Check the right angle drive rotation (figure
24 and figure 25) before installing it on the
bracket. Align the right angle drive shaft with
the gearbox hollow shaft and tighten all
screws.
10. Reinstall the speed reduction gearbox
assembly on the vehicle mounting bracket
without tightening the screws.
11. Using shims and, for the front slide-out, the
vehicle mounting bracket adjustment screw,
align the right angle drive shaft jaw coupling
with the slide-out lower shaft jaw coupling.
12. Reinstall the motor on the speed reduction
gearbox (see section 6.2).
13. Reinstall the universal joint and the jaw
coupling on the right angle drive. Use the
motor output shaft to align the keyseats.
14.
For the front slide-out: Reinstall the
reinforcement plate
8. RIGHT ANGLE DRIVE
Caution: The right angle lower vertical key must
be welded or punched on its keyseat to prevent
it from moving or falling.
The right angle drive simultaneously transmits
the movement to the lower and upper driving
shafts via a vertical shaft. To preserve the same
rotating speed, before being transmitted to the
upper shaft, the movement coming from the
speed reduction gearbox passes through a
second right angle drive, which has a 1:1.5 ratio.
That is due to the fact that the lower shaft
pinions have more teeth than those on the upper
shaft.
8.1 MAINTENANCE
Inspect the right angle drive to check if there is
any leakage or excessive backlash in the box or
between the keys and their keyseat. Replace the
keys or the right angle drive if excessive wear is
present. When replacing, weld the lower vertical
shaft key on its keyseat. Check that all bolts are
tight.
Check the oil level and lubricate the right angle
drive once every three years.
Check the right angle drive axle alignment with
the driving shafts and adjust it if necessary,
using the shims and/or the adjustment screw.
8.2 LOWER SHAFT RIGHT ANGLE
DRIVE REPLACEMENT
Use the same procedure as for the speed
reduction gearbox (section 7).
