The Workman 200 Sprayer (serial numbers below
290999999) uses three boom valve motor assemblies
to control the spray booms. Each boom valve motor as-
sembly includes a motor section (Fig. 29, Items 1
through 7), a spindle s ection (Fig. 29, Items 8 through
27), anda manifold assembly(Fig. 29,Items 28through
33).
Disassembly and Inspection (Fig. 29)
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 spray control from machine. Separate
spray control c omponents to allow boom valve motor
disassembly (see Spray Control in this section).
2. To remove the motor and spindle section assembly
from the manifold assembly:
A. Remove thefork (item29) 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 boom 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 sec-
tion.
