The boom spray valve manifold assembly includes the
right, center and left spray boom valves. Each of the
boom spray valves include a bypass valve.
IMPORTANT: Each valve actuator has an internal
circuit breaker to protect the actuator motor. The
circuit breaker should reset in 20 seconds after
power to the actuator is removed.
Removal (Fig. 17)
1. Park machine on a level surface, stop spray pump,
stop engine and engage parking brake. Remove key
from ignition switch.
2. Label boom spray valve manifold hoses for proper
installation. Disconnect hoses from boom spray mani-
fold.
3. Label spray valve wire harness connectors for prop-
er installation. Disconnect wire harness connectors
from boom spray manifold.
4. Remove pressure gauge tube from coupler on right
side of boom spray valve manifold assembly.
5. Remove flowmeter from boom spray valve manifold
(see Flowmeter Assembly in this chapter). Discard gas-
ket between flowmeter and manifold assembly.
6. Support boom spray valve manifold assembly and
remove four (4) flange nuts (item 27) and flange head
screws that secure boom spray valve manifold to
mounting plate. Remove boom spray valve manifold
from machine.
7. Disassemble boom spray valve manifold as needed.
Discard any removed O−rings and gaskets.
NOTE: See Valve Service (Serial Number Above
315000000) and Bypass Valve Service (Serial Number
Above 315000000) in this chapter for disassembly and
assembly information of the valves and valve actuators.

Installation (Fig. 17)
NOTE: Replace, do not reuse gaskets and O−rings.
Coat O−rings and gaskets with vegetable oil before
installation to reduce damage during assembly.
1. Assemble boom spray valve manifold.
2. Secure boom spray valve manifold assembly to
mounting plate and secure with four (4) flange nuts
(item 27) and flange head screws.
3. Position new gasket between flowmeter and boom
spray valve manifold. Install flowmeter to boom spray
valve manifold (see Flowmeter Assembly in this chap-
ter).
4. Using labels placed during removal, install hoses to
manifold assembly.
5. Install pressure gauge tube to coupler on right side
of boom spray valve manifold assembly.
6. Using labels placed during removal, install wire har-
ness connectors to manifold assembly.
7. Operate spray system and check for leaks. Repair all
