Drive Motor Disassembly

SERVICE

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.

IMPORTANT

Use a rag in the bottom of the removal tube to protect the

automatic valve body when it drops out.

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.

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 identiﬁed 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.

IMPORTANT

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.

ASSEMBLY

DRIVE MOTOR REASSEMBLY

1.Support the four corners of the motor plate (making sure it is level) in an arbor press.

2.Press bearings in place using Bearing Installation Tools (part numbers 05044 and 05061) with the bearing split lines facing each other.

IMPORTANT

Make sure bearings are pushed in straight.
