How to separate pump from motor - Pentair 1 hp WhisperFlo InGround Pool Pump WFE24 ()

See if this helps:

take bolts out to separate wet end of pump and motor then remove screw if one on impeller sometimes they are backwards threads take screw out then unscrew impeller while holding shaft of motor that should be a regular thread separate backing plate from motor change seals then revese

If you are just talking about the windshield washer pump/motor that squirts water on the front windshield, there is no separate fuse for that pump. If you are talking about the front windshield wipers themselves then the fuse for that (including the washer pump) is located is the fuse panel inside the vehicle down below and to the left of the steering wheel. Below is a diagram of the fuse layout (first picture) and I marked the 10 amp fuse for the system. As I said if you are talking about the pump/squirter motor there is no separate fuse. Inside the wiper motor itself (located basically on the firewall on the drivers side) is an internal microprocessor as well as an internal relay for that pump. If the processor or the relay is bad, both are internal and the whole wiper motor assy. has to be replaced. It's one complete unit. There is a chance that the pump motor itself could be bad. In the second picture is a breakdown of the washer fluid reservoir. In order to get access at it which is where the washer pump motors are located the right front wheel and splash guard have to be removed. I have marked the 2 washer pump motors which are mounted on the reservoir. I cannot tell you which motor is which but the one for the front has 2 wires at the connector (a black & white wire and a black wire) The rear pump motor has a violet & light green wire and a black wire at its connector. That's how you can tell which one is which. You can test the motor by either pulling it out and applying direct power and ground to it to see if it engauges or while someone is engauging the washer inside the vehicle while you are down there, see if you are geting power at the black and white wire. Check that wire while it is disconnected and using a good separate ground. If you are getting power make sure the black wire is geting a good ground. If all is good (ground & power) than more than likely the pump motor is bad. If you have a power supply problem at the black & white wire than you are looking at most likely a bad wiper motor assy but check for an open power wire from the wiper motor to the pump motor. It's not quite as simple as it used to be. The wiper motor on your vehicle has like a mini computer in it. I'm gonna say the washer pump motor is bad which is the most common. Hope I was able to help and that I didn't get too technical on you but things are not like the old days with separate motors (wiper and washer).

I believe the part you actually want is the motor endbell that houses the front motor bearing and it in turn allows the motor to be connected to the pump housing. The number you give is the motor model number...I will also need the motor serial number to ensure we quote you the correct version of the endbell you need as there are design changes from time-to-time. Please email than information to me via the contact us part of our website at www.arrowmotor.net. You should be able to purchase the endbell assuming AOSmith still makes it.

Separate pump and motor. Remove diffuser. Remove back cover from motor. Motor shaft has either a slot for a screwdriver or a flat area for a wrench. Hold shaft and unscrew impeller.

1. Disconnect the booster pumpset from the power
supply.
2. Take the pump frontcase off by taking the bolts
holding it.
3. Take the pump impeller from the shaft. This is
either bolted or screwed to the shaft that is
actually an extension of the motor.
4. Carefully take the mechanical seal off from the
shaft.
5. Unbolt the pump backcase, from the motor,
6. Now you have the motor separated from the pump.

Pull the pump's front cover, lock the opposite end of the motor shaft, unthread the impeller, loosen the 4 motor thru-bolts then you can pull the seal plate.

FROM WHAT I CAN SEE ON MY SCAMATIC THE PUMP HAS A MECHANICAL SEAL, THE PUMP IS FROZEN TO THE MOTOR YOU CAN GET THIS APART BY TAPPING WITH A PLASTIC MALLET AND PATIENTS THEY CAN BE TOUGH SOME TIMES

Remove the back cover from the motor, lock the shaft in place, thread off the impeller.
