REPLACING Pump/Motor:
SINGLE PUMP SPAS:
110vac, 2 Speed Pump;(part #2500-255 standard duty pump/motor complete;
#CC-F570HD heavy duty pump/motor complete; Pump Only: #CC-2jp)
If your spa has only one pump, You have a 110v, 2 speed pump that serves as
both low and high speeds.
Removal:
Turn main power off. Drain the spa. Most Jacuzzi models do not have
valves to close to avoid draining the spa. Once the spa is drained, disconnect the
2 couplings attached to the pump (wet end). Normally you can hand loosen but
occasionally you will need to use a large wrench to loosen. You can also use a oil
filter wrench to loosen. (see Chapter XX for specific spa suggestions)
Next: The motor itself is attached by four nuts at the feet. There is likely
a copper bonding wire attached to the motor. Remove. Unplug the pump cord
from the control box.
Remove pump/motor assembly.
Disassemble Pump (wetend).
A. Remove 4 bolts holding the front face of the pump (volute) to the pump
housing.
B. You will see the eye-seal on the nose of the impellor and the impellor.
You will want to disconnect the impellor from the motor shaft. The motor shaft
screws into the impellor. The intended method to separate is this: on the opposite
end of the pump/motor assembly, in the middle, is the motor shaft end. It has a
slot. Take a large slotted screwdriver and while holding the impellor stationary
with one hand, turn the motor shaft with the other. If this doesn't work, reverse
focus and turn the impellor with your hand while holding the motor shaft
stationary. In worst case situations, you can grab the motor shaft between the
pump and motor with a pair of vice grips and hand turn the impellor loose. If that
doesn't work, you will have to use a wrench on the impellor to separate. This will
likely damage the impellor and will need to be replaced.
C. Once the impellor is separated you need to disconnect the pump
