ACTUATOR DRIVE NUT ADJUSTMENT
This manual section explains the steps for adjusting the drive nut (housing assembly) setting for the machine’s scrub deck actuator motor. Reference
the chart below that shows the IN & OUT dimensional specifi cation for the actuator motor that is used on the AquaRide

Part # Actuator Motor Drive Nut Housing Assy IN Drive Nut Housing Assy OUT
56393303 Scrub Brush Lift (all) 1/4” (6.3mm)* 3-7/8” (98.5mm)*
*The “Drive Nut Housing Assy IN/OUT Position” dimensions are measured when completely assembled. Reference points are the edge of the plastic
Spring Housing Assembly as shown in Figure 3.
General Instructions for All Actuator Motors
1
See Figure 2. This shows the special actuator
power cord adapter (PN 56407502) that is
needed to connect the machine’s battery
pack and actuator motor for setting the drive
nut limit settings.
2 Open the machine battery compartment and
disconnect the battery connector. The battery
pack is needed to power the lift actuator motor
to properly set the IN & OUT limit switches.
3 Connect the actuator motor to be tested to
the power cord adapter end. Then connect
the alligator clips from the cord adapter (red
clip to the positive and black to negative) to
battery connector or battery posts. The rocker
switch is used to change the motor rotation in
setting the correct drive nut dimension.
Instructions for Scrub Brush Lift Actuator Drive Nut Adjustment
1 See Figure 3 and 4. On a new scrub lift actuator motor remove (spin-off) the Drive Nut (A) fi rst slide on the short compression Spring (B) onto
the actuator (lead screw) shaft. Next reinstall the plastic drive nut as shown (with the nut pin pocket away from the motor). Then fi nish assembly
of remaining parts (long compression spring, Spring Housing (C) and mounting hardware).
2 Hold onto the spring housing assembly and press the rocker switch to run the drive motor and retract the spring housing towards the motor
housing (its IN limit).
3 Measure the position of the spring housing assembly on the actuator shaft. Manually turn the spring housing assembly to the appropriate IN
position shown in the chart above.
4 Hold the spring housing assembly then press the adapter cord rocker switch to run the drive motor to the OUT position (wait until the motor
stops).
5 Measure the position of the spring housing assembly on the shaft and compare the measurement with the OUT position shown in the chart.
6 When the measurement doesn’t match the dimension shown in the chart it is necessary to remove the Adjuster Cover (D) and adjust the OUT
position.
7 To increase the travel of the spring housing assembly, turn the adjuster clockwise. To decrease the travel of the assembly, turn the adjuster
counter clockwise.
NOTE: Use a 1/2” (13mm) socket to turn the adjuster. Each click of the adjuster will change the spring housing assembly travel 1/16 inch
(1.6mm).
8 After each adjustment, hold the spring housing assembly, run the actuator IN & OUT and check both dimensions. After checking that the spring
housing limits are set correctly replace the adjuster cover. Service Tip Note: Use the above power cord adapter to help position the spring
housing assembly (in or out) for ease in actuator motor installations.
9 After adjusting the actuator spring housing dimensions, follow the Scrub Brush Lift Actuator Removal manual section to reassemble.
Service Tip: See Figure 4. Note the correct orientation of the Spring Housing (C) when installing the complete motor assembly and also run the
spring housing assembly to the IN (retracted) position for machine installation.
