5. To remove the fl ow sleeve from the fl ow sleeve tube, re-
move the automatic valve body and associated parts from
within the fl ow sleeve removal tube and continue pushing
on the fl ow sleeve until it drops out.

DRIVE MOTOR DISASSEMBLY
1. Place an aluminum plate in an arbor press.
2. Place the motor assembly (drive motor control block as-
sembly, motor chamber, motor plate and associated parts)
on the plate with the latch facing upward. Rotate the latch
to the open position and use Latch Removal Tool (part
number 05045) to press down on the spring backup to al-
low removal of the wire retaining ring.
3. Remove the latch, latch washers, springs and spring
backup.
4. Place the motor assembly in a bench vise (do not
overtighten), then remove the two 3/8-16 x 1-3/4 inch
capscrews and two 1/2-13 x 4-1/2 inch capscrews.
5. Separate the three parts of the motor housing and re-
move the idler gear, drive gear and key, allowing the drive
hex to be pushed out through the drive motor control block
end of the drive motor chamber.
Do not pry between motor parts with screwdrivers or
other tools since this may damage seal surfaces. Do
not attempt to remove the drive hex before the drive
gear and key have been removed.
6. To remove the motor control valve assembly, loosen the
set screw in the lever and remove lever. Remove the retain-
ing ring and reattach the lever to pull the valve assembly
out.
PRIOR TO ASSEMBLY
Clean all parts with a degreasing solvent.
Obtain seal kit (Part Numbe 05839) so all seals exposed
during disassembly can be replaced during assembly.
Ensure that all seals that were exposed have been re-
placed with new parts.
Apply clean grease or o-ring lubricant to all parts during
reassembly.
Note:
For orientation of parts identifi ed in the following proce-
dures, see the parts list exploded view illustration at the
back of this manual.
1. Check all parts for evidence of excessive wear, scoring,
or obvious damage. Pay particular attention to seal and
other running surfaces, looking for scratches or other signs
of fl uid contamination caused defects. Dirty or water con-
taminated fl uid can cause scratches on running component
surfaces.
2. Examine all exposed seals and o-rings for worn spots
or damage caused by overheating or ingestion of contami-
nants. Although all exposed o-rings and seals must be
replaced during assembly of the unit, this inspection should
be performed to help identify related faulty components and
the cause of an experienced or potential malfunction.
3. All components exhibiting excessive wear or deep
scratches can usually be touch up using emery cloth. Thor-
oughly clean all parts before assembly.
4. Apply clean grease or o-ring lubricant to all close fi tting
parts and seals during assembly.
