motors. They all were 48y frame motors.
Lastly, in the industry the motor is motor only, pump is the wetend, and when they
are together, they are called pump complete.
PUMP/MOTOR
The motor takes electrical current and turns the shaft clockwise. Although
individual parts may be available, usually bad motors are replaced not repaired.
REPLACING JET Pump/Motor:
Removal:
Turn main power off. Drain the spa. Most 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.
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 nose of 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
bracket or body from the motor. It is held by 4 long bolts that run through the
motor and bolt to the pump. Disconnect each bolt but DO NOT pull the bolts out.
