Removal (Fig. 89)
Machines with serial numbers below 400000000 were
originally fit with a model 363 spray pump. Machines
with serial numbers above 400000000 use a model 364
spray pump. Check the manufacturers build plate on the
pump to verify the pump model being serviced.
IMPORTANT: Make sure to neutralize and remove
chemicals from pump and hoses before loosening
and removing spray system components.
1. Park machine on a level surface, stop engine, en-
gage parking brake and remove key from the ignition
switch.
2. Disconnect hoses as follows:
A. Remove fork from pump output fitting (item 4
Fig. 90) and separate tee from pump output fitting.
B. Remove fork from the bottom of the lower suction
tee fitting (item 11 Fig. 90) and separate tee from
pump suction hose.
3. Remove connector forks and disconnect hoses from
agitation throttle valve (item 26). Position disconnected
hoses away from pump.
4. If present, remove cap screw securing clamp
(item 25) to valve bracket.
5. Loosen, but do not remove, two (2) flange head
screws (item 15) and flange nuts (item 18) that secure
control manifold/motor assembly to motor mount plate
and remove guard from machine.
6. Remove two (2) set screws that secure coupler to
pump shaft.
7. Remove four (4) flange head screws and flange nuts
that secure spray pump to pump bracket.
CAUTION
To prevent personal injury, make sure that pump
is properly supported as it is removed from the
machine. Pump assembly weighs approximately
125 pounds (57 kg).
8. Slide pump out until shaft is removed from coupler.
Locate and retrieve woodruff key from pump shaft.
9. Remove pump assembly (Fig. 91) from machine.
