﻿﻿Hey, it's Ralph, Inyo pools. Today we're going to show you how to
replace a motor on a Sta-Rite Max-E Pro.
First thing you want to do is go ahead
and shut the power off of the breaker.
The first thing you want to do is take
this metal clamp off that'll separate
the back half of the pump from the front
half which stays plumbed in line.
Let's loosen this up.
All right.
Once you get the clamp off, you can
separate the motor on the front half there.
We slid the motor back, now we have to remove the wires.
First one that we're going to remove is the bonding wire down here.
That's just connected by little quarter-inch socket here.
We're going to loosen up this screw in
the back of this cap, the quarter-inch socket.
Take the cap off and then we're going to remove these
three wires you got a ground and the two hot lines.
Loosen up this conduit adapter.
All right, there we go.
Now we can take the motor over to a table where it's easy to work on.
Next, we're going to remove the diffuser.
I'll remove these six screws.
Okay, then you can pull the diffuser off and it'll expose the impeller.
What you'll do before you remove the impeller,
you have to stabilize the back of the shaft.
You can use a half-inch wrench to stabilize the shaft.
We got to stabilize in the back, now we're going
to spin the impeller off counterclockwise.
Sometimes the impellers are pretty hard to get off, so you
might want to use a strap wrench to help loosen it up.
We're going to remove these four bolts that secure the motor
to the seal plate and we use nine-sixteenth-inch wrench.
Next you can slide the plate right off the motor.
If it doesn't come really easy, you can
use a rubber mallet and pop it right off.
Now you want to remove the old shaft seals, there's two-part seal.
You can remove the spring portion from the impeller
and pop the old ceramic shaft seal out of the plate.
There you go.
One more thing with the spring portion,
sometimes when you pull that
off the inside there's like a metal sheath and it stays on the shaft.
When you go try to put the new spring portion on, you
can't get it on, you think you might have the wrong size.
If there's a metal piece still on there, you want to remove it.
I'm going to make sure the spot for the new seal's nice and clean.
Just wipe that off with a clean cloth.
The shaft seal is the two-part seal.
You're going to want to put the white ceramic side
facing out, you put that into the seal plate.
Then, the spring portion, there's a metal side with
rubber on it and then there's smooth black side.
You want that smooth black side to be touching
the white ceramic when you put it together.
First, we'll put the white ceramic piece into the seal plate.
You don't want to push that in-- You don't
want to put your fingers on the white ceramic.
You want to press that in with a clean cloth.
Make sure it's nice and snug in there.
Then, you're going to put the spring
portion on the shaft of the impeller.
Again, it's that smooth black side facing out.
Slide that all the way down the shaft of the impeller.
Again, you want that smooth black side to be
touching the white ceramic when you put it together.
We're going to put the seal plate back on the new motor.
All right.
Before we can put the impeller back on we got to
take this cap off so we can stabilize the shaft.
Okay, to stabilize the shaft we're
going to use a seven-sixteenth wrench.
You just slide it in behind the thermal
overload at the top and then you just spin
the shaft until it locks into place
and you'll feel it drop down and it's locked.
All right.
Then you can slide the impeller on, spin
it clockwise and just keep tightening
until it starts to turn the wrench in
the back, you don't have to overtighten.
Okay.
Before you put the diffuser back on you
want to replace the diffuser O-ring.
We'll take the old one off and get the new one
and you want to put some silicone or Teflon
lubricant on the O-ring and you don't need a lot,
you just need enough to make the O-ring shiny.
It's usually just a pea-sized amount is enough
and then you can slide that on the diffuser.
Then you could pop the diffuser in place
and we'll get the diffuser screws and tighten those.
All right.
There's a wiring diagram on top of the motor that you can follow but
basically, the motor come is dual voltage but it comes to on 230.
There's a little knob down here that you
could switch if you want to turn it to 115.
The installation we're doing is 230 volts so we'll
have two hot wires coming in and the ground.
The green ground line will go to this green screw and the black
and red hot wires, one will go to L1 and one will go to L2.
It doesn't matter which way because there's no-- it's not going to run
backwards or anything so it doesn't
matter which one goes to which terminal.
We've got it wired up, we got the green going to the ground.
We got the two hot wires going to L1 and L2.
We ready to put the cap back on, tighten
the two screws, and then slide it into place.
Last part of wiring it's going to be
the bonding wire, just reconnect that.
Okay.
Before we put the two pieces back together at the pump.
We'll replace the housing, O-ring.
Again, just use a little bit of silicone or Teflon
lubricant and there's a groove in the plate here.
All right.
We got the clamp on or you can tighten the knob.
As you tighten it, you can kind of tap it loosely with
a rubber mallet, make sure you are getting good contact here.
All right.
We've got the motor installed.
The only thing you have to do is prime the pump
before you turn it on and that should be it.
