Note that the purpose of this section is to
show you how to remove & install a spa pump wet end and new pump
motor. While every effort is made to be sure that virtually
all areas of complexity are covered, you may find it more difficult or
sometimes easier to accomplish this task. Use common sense. If the
wet end that you have on your spa is a lot different from what is depicted
here, then do not use these instructions. This is page 2 of this
procedure.
Safety Warnings!
| Remove Power from the spa/hot tub BEFORE performing this
procedure. Failure to comply with this requirement, can lead to
electrical shock and/or electrocution! |
Disclaimer
|
| The
instructions here are intended for general reference only. Many pumps
are different from the one depicted here, and may require more or less
mechanical effort or knowledge in order to achieve the desired
results. |

Since this is a new pump motor, we must first remove the through-bolt
retaining nuts so we can attach the wet end. |
|
 |
 |
| First remove the motor rear
cover to gain access to the wiring connections and the armature
shaft. |
|
| Use Waterlube brand
anti-corrosion lubricant to coat the pump shaft and the water slinger.
This will prevent shaft rusting in the future, which can lead to premature
front bearing failure, and splitting of the impeller. |
|
|
 |
 |
Assemble the pump
spring seal on the impeller shaft. On a center discharge style Aqua-Flo
wet end, there is a small rubber o-ring that goes on 'before' the spring
seal. With this in place and seated, put the impeller into the wet end
housing.
|
 |
 |
| Lubricate the housing o-ring
with Waterlube lubricant to ensure a positive, long lasting
seal. |
|
| I like to put Waterlube just
about anywhere that corrosion control is an issue, particularly on the threaded
inserts to prevent corrosion of the screws. |
|
|
 |
| Carefully put the lubricated
o-ring back on the cover plate and assemble the two halves together, then
tighten the cover screws. |

wet end is now complete, click to go on to the
