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.
They also hold the motor together and removal will likely cause the motor to
disassemble.
D. If you are replacing the pump (wetend), reverse. If the motor shaft is
corroded, you need to remove the rust. The least abrasive method is best. Start
with steel wool, then try a wire brush or even sandpaper. You need to have a
clean motor shaft so the impellor can tighten cleanly against the seal and make
the seal work. If the motor shaft is highly corroded, the new impellor will not
tighten against the seal and the pump will leak.
E. If you are replacing the motor, you have to move the motor cord from
the old to new. The motor is only a 110-130vac motor so you don't have any
internal wiring to change for the new motor. The sequence of wiring is the same
for either an Emerson or an AOSmith/Magnatek motor. The top wire connection
is the white (neutral) wire; the middle is the red (high) wire. The bottom is the
black (low) wire.
Extra Help:
If you strip the bolts that hold the pump face (volute) to the J-light pump housing
(bracket), you can easily buy a long bolt and nut locally and insert that through the
hole and tighten. You must tighten all four bolts to snug. If not, the pump will
eventually leak.
On a few models, access to the pump/motor is difficult. Because the pump/motor
is behind the piping and control box, I have found often it's best to remove the
piping and in a few cases, the control box itself to get to the pump.
"Z" Models made from late 1996- early 1998 often have only a limited access
panel of about 3 feet. The rest of the spa panel is one piece on each side.
Because each side's panel is built as one piece and screwed into various points
for strength, the only way to remove is to lift the spa up to get to screws that were
placed in upward angles. It's quite a project. You should consider building a new
side panel and cutting a hole through the existing panel. The amount of effort to
remove the side is more than the time and effort paid to build a new side panel.
This is only applicable to those few production models that only have a small
access panel in front of the equipment.
