There are 4 screws that go in through the back side all the way to the front by the shaft. You can purchase the screws from a dealer in your area that sells the motors.

Is the frame size of the flo master pump the same as the bolt pattern that holds the pump to the motor ?

Frame size is not the same as the motor mount footprint.
If your motor does not have the frame size written on the spec label. You can measure the motor diameter.

This is a Speck swimming pool 1.5kw pump I need to replace the motor stator bearings but don't know how to take the pump impeller off

This is the most popular pump frame. The motor will actually have a square flange as an integral part of the motor (not the pump) on the front of the motor with 4 holes (one hole in each corner of the flange). The pump body will be secured to this square flange with 4 bolts, which are outside the round barrel of the motor. Caution: Make certain the square flange is part of the motor; not the pump body. Many pumps are square and may appear to be part of the motor. Removing the motor from the pump will allow you to make certain how the pump is fastened to the motor. How the pump is fastened to the motor determines the basic type of frame.
Note: Also, some 48Y frame motors are actually thru-bolt style; therefore, check the mounting bolts to make certain they are not thru-bolt style as described below.
Not a square flange on your motor? If you do not see a square flange as described above for the square frame motor, then you have a pump body, which mounts to the motor with 4 bolts accessible inside the pump case. This non-square frame will be a thru-bolt style frame, 56J frame, or 56C frame. How to determine if you have a 56J or 56C frame: The pump body mounts to the face of the motor with 4 bolts just inside the circumference of the motor barrel. To see these mounting bolts, you must take apart the pump body and look inside the pump. The bolts will be fastened into the face of the motor with threaded holes. 56J frame: If your pump body mounts into the face of the motor as described in the previous paragraph, and the impeller is threaded onto the motor shaft, then you have a 56J frame. Additionally, the impeller may be secured with a small screw, which is threaded into the center of the motor shaft. If the outside of the shaft is not threaded, maybe you have a 56C frame. 56C frame: If your motor has a shaft with a key-way (small metal key slides into a groove machined along the length of the motor shaft), then it is a 56C frame. These are very rare in today's pumps. If your pump is 20 years old or older, it may have a keyed shaft (56C), but even then is unlikely. The keyed shaft may also have an internal tapped thread to help hold the impeller once it slides over the key-way. Thru-bolt style frame: The motor mounting bolts are the key with this style of motor. Like the name implies, if the pump fastens with nuts to the 4 bolts, which pass all the way thru the motor, then you have a thru-bolt frame. These extremely long bolts (8 inches or longer) will go through the motor. These motors are popular on spas and above ground swimming pool pumps. NOTE: Sometimes these motors are also labeled 48Y frames, but they are not square flanged 48Y frames. Once you determine the frame, click on the link and view some motors to help determine horse power by analyzing the amperage comparisons.

How do we remove the wety end from the motor?

You have what they call a" Through Bolt" motor. The bolts are located on the back of the motor and run the length of the motor. I believe they are a 5/16 bolt. Just a note..Price a whole pump vs a motor,seals and possibly a impeller first.Sometimes it is cheaper and you get all new parts.

Can't get the 4 motor to housing bolts off sp 1515-z-1 esc pump motor without twisting bolt into. have broke one as of now. Trying to replace pump seal. instructs say to remove 4 motor bolts to housing and...

Thank you for posting your question here on

As a rule, when we get those pumps in for repair and the bolts are breaking you notice the motor shaft is severely corroded as well. Often times that will make the unit unrepairable as the new seal won't hold up on a damaged motor shaft. If that is your case you will want to at least consider a new motor and seal for the pump.

If you can remove the bolts with or without breaking you can precede to attempt the repair. Bear in mind you will need to get the busted tips out of the pump housing in order to install the new bolts. That is not an easy task as you are working with a small brass bushing in a thin plastic leg. The removal easily damaged the pump housing. Try to work the bolts back and forth to free the tips. You will then need to get the broken tips out. If all goes well and the shaft is not too bad you should be ok. Anything goes wrong, replace the motor and seal and you'll still save some $$$ compared to a whole new pump.

If this answer does not fix your problem, please comment with additional details prior to rating the answer. Positive feedback is appreciated once your problem is solved!

Where cani find replacement thru-bolts for an Aqua Flo XP2 pump?

A local motor repair shop would have the thru bolts. If you have at least one good one, you could match up the size, and cut soem threaded rod. Most motors this size use either 8-32,10-24,or 10-32 bolts. You can buy threaded rod at hardware store. Try to find galvanized, to prevent corrosion, or paint the part inside the motor if you cannot.

How do you pull apart a pool pump to replace the bearing onga pomp

Assuming the pump is at your working table, do the ff;
1.Unscrew the bolts holding the pump case.
2. Take the impeller and the mechanical seal off the
pump shaft.
3. Now you can take the motor off the pump by
unscrewing the bolts holding the motor and pump.
4. Then, you can dismantle the motor by unscrewing
the four long bolts holding it.
5. Take the back plate off and the centrifugal switch
on the shaft. Mark the original location.
6. Now, you can pull the rotor out, by a slight force
at the back plate side of the motor shaft. Note
that the front plate hold the bearing is bolted.
The front plate goes out with the rotor.
7, Now you can change the motor bearings.
To reassemble, the procedure is the reverse of what you just done. Send your e-mail for further assistance.

How do I replace water pump[ on my 1993 buick park avenue.

Most often you do not need to totally remove the right motor mount. GM unfortunately made one bolt on the water pump that you can't get to w/o messin with the motor mount. There are actually two bolts that have access holes in the motor mount but in many cases you can get at and remove the one bolt with some clever maneuvering and the right tool. Yet that leaves the other ****** bolt. Now this is the PO factor....just one bolt you know some idiot designer left to make every bodies life difficult. So here is how you do it step by step. Loosen the bolts on the water pump flywheel then remove the belt. Take a oil-pan length 2x4 and use it in between jack and oil pan and jack up engine almost so that steering pump fluid cover on top side almost hits cross bar. Remove the center bolt of the motor mount holding the two halves of the mount together. Remove two bolts and one nut on the engine side mount. Remove 4 bolts (2 on top and two hidden on side) of the bolts holding the mount to the frame. Now take a big 2x4 and wedge it so as to move the engine to the driver side of the compartment. At the same time rotate and move the mount piece on the engine side--rotating about the stud [that the nut came off of]--so as to partly split apart the two mount halves. You'll see that you can now get at the two hidden bolts. Remove the water pump pulley wheel. There are a bunch of small and little bolts in the water pump...some on bottom side. Remove them and old pump. Scrape off old gasket. Apply new gasket and sealer to new pump and reverse order to install

the shaft seal is connected to the rotor shaft inside pumps assembly,there are 4 bolts holding pump casing front cover loosening this will appear the centrifugal blade connected to rotor shafting holiding by a big nut at tip of rotor shaft.loosen this by socket wrench try to find the size,then pull centrifugal blade with
the shaft seal,buy this one with same specification exact value of shaft seal,if there is mistake buying seal either leak again or to tight.shaft549ea12.jpgso this type is just sample to have idea,afterr you purchased put it back and reassemble the pump motor.thi is easy one, have a nice day don't forget to rate me. thank's

Motor mounts to access water pump

You must loosen the motor mounts on the body of the car. I did not disconnect the motor mounts completely to get at the water pump bolts. One ALL motor mount bolts are removed I jack up the motor with a floor jack.
