Disassembly
1. Remove swivel assembly (Figure 22) from the
top of the Dorado™ Automatic Pool Cleaner by
turning it 1/4-turn counterclockwise and pulling
straight up on it.
2. Turn cleaner upside down. Remove 6 screws and
remove lower body assembly from shroud.
3 . Turn lower body assembly right side up. Unsnap
the 2 clips on the oscillator chamber cap (Figure
23a); lift it off.
4. Pull the long gear shaft straight up (Figure 23a)
by the blocks on the ends of the shaft. Hold the
seals in the oscillator and the blocks on the shaft.
The cam may interfere with the shaft mounting
post; if so, turn it slightly on the shaft until it
clears the post. The shaft assembly can now be
disassembled (Figure 23b).
5. Slide the long gear shaft out of the oscillator (with
gears, complete); make sure that you don’t lose
the seals out of the oscillator which may fall out
at this point (Figure 23b).
5A. Oscillator seals are replaceable.
5B. Ratchet gear set and long shaft are replaceable
as a unit.
6. Remove the set screw, short gear shaft, and
gears (Figure 24); be sure to keep the gears on.
7. With a small screwdriver (such as a jeweler’s
screwdriver), a pencil, or a pen point, depress
and remove the coil spring from the lift brush
mounting post (Figure 25). Replace the brush
and the spring if necessary.
8. The metal ratchet tab slides out of its slot
sideways; replace it by removing the center
brushes and sliding in a new ratchet tab until it is
flush with the edge of plastic holder (Figures 26
and 27). Replace the center brushes.
9. The brush ring pops out of the cleaner body for
easy replacement.
10. If you need to replace the bumper, turn the
shroud and bumper assembly upside down and
remove the two screws holding the bumper to the
shroud.
