A Multi Pro 5700--D sprayer with serial number below
310000000 uses three valve motor assemblies to con-
trol the spray booms andone valve motor to controltank
agitation (Fig. 31). Each of these motor assemblies in-
cludes a motor section (Items 1 through 7 in Figure 30),
a spindle section (Items 8 through 27 in Figure 30), and
a manifold assembly (Items 28 through 36 in Figure 30).
Disassembly and Inspection (Fig. 30)
IMPORTANT: Make sure to remove and neutralize
chemicals from spray components before disas-
sembly. Wear protective clothing, chemical resist-
ant gloves, and eye protection during repair.
1. Remove valve motor assembly from machine (see
Agitation Valve Motor Assembly or Boom Valve Motor
Assembly in this section).
2. To remove the motor and spindle section assembly
from the manifold assembly:
A. Remove the fork (item 29) that secures the motor
and spindle sections to the manifold assembly.
B. Lift the motor and spindle section assembly from
the manifold.
3. To allow easier separation of the motor and spindle
sections, make sure that valve motor is in the closed
position (green indicator is recessed into the spindle
housing). Remove four phillips head screws (item 15)
and separate spindle section from motor section.
