BRUSH DECK ACTUATOR REMOVAL

1

Lower the scrub deck with the scrub brushes installed. Don’t turn the key switch off until disconnecting the battery pack by using the emergency
disconnect lever (13). This procedure is done to prevent the scrub deck from automatically raising when the key is turned off.

2 See Figure 3. From underneath the machine remove the clevis Mount Pin (K) that secures the lower actuator housing to the scrub deck mount

bracket.

3  Disconnect the brush lift motor wire harness at the motor.
4  Remove the top actuator (inspection) Cover (L) held with (3) screws. Cover location operator’s compartment below front of seat.
5  Remove the Hairpin (M) then slide the upper Mount Pin (N) out from the chassis mount bracket.
6  Remove the complete actuator lift motor assembly from underneath the machine. Note: Do not turn or reposition the drive nut on the actuator

shaft, mark if needed.

7 Important: After removing the actuator motor and before replacing a new motor or drive nut the IN & OUT limit switches must be set (or checked)

to their correct dimensional specifi cations (see the electrical section for the Actuator Drive Nut Adjustment instructions).

8 To disassemble the Drive Nut (O) from the actuator shaft, remove the (2) Screws (P) and separate both Retainers (Q & R) from the Spring

Housing (S).

9 Remove the (4) spring housing retainer Screws (T) and slide the spring housing and (long) Compression Spring (U) from the actuator shaft.

Next spin the drive nut off the shaft and save the top (short) Compression Spring (V). Note: See the Actuator Drive Nut Adjustment section in
this manual to properly install a new drive nut.

10 After adjusting the drive nut follow steps 1-9 in reverse order to re-install the scrub deck lift motor in the machine.
Service Tip: Wrap a small amount of tape around the spring housing to prevent it from spinning out of adjustment.
Service Tip: Shown in the Electrical System is the actuator power cord adapter PN 56407502 and instructions for use. This tool can be used to
help position (raise or lower) the drive nut housing for ease in the actuator mounting pin installations. An additional method to control the output
to the brush lift actuator for installation and removal is to read the instructions in the Service Test Mode section for the special output control of the
Maintenance Mode Switch (D) (See Electrical System for steps to enter the Service Test Mode).
