Might be a screw in middle of impeller with reverse thread. If so, remove. Remove back cover of motor, hold center shaft with wrench and unscrew impeller from shaft.

How is the pump seperated from the motor. I am replacing the motor only.

From this question I assume you already have a motor. Anyway, most motors separate from the pumps by first taking apart the pump and removing the impeller. Some impellers have a screw in the middle that have left handed threads. Once this screw is removed the impeller can be unscrewed by holding the motor shaft with a wrench and turning the impeller counter clockwise. To gain access to the motor shaft to hold it there usually is a cover at the end of the motor that comes off. When the impeller is off there are usually bolts that hold the pump to the motor. When reassembling the motor it is important to replace the ceramic seal and gaskets. I hope this helps.

I'm trying to remove the motor from the back of my Hayward pump (Northstar). I've loosened the large, round locking housing that secures the motor to the pump. It appears the motor should now just slide...

You didnt mention removing the impeller before trying to "slide it out" Remove the impeller and diffuser first before trying to seperate the two pieces. Lock onto the rear shaft with a 7/16th" wrench while rotating the impeller counter clockwise until remoed. Now you can seperate the two halves.

Motor very hard to turn. Bearing at end with power cord turns freely. Bearing against the pump hardly turns. How do you remove the pump and get to the bearing to replace? Should the pump be replaces as...


to answer the question "should the pump be replaced as well?)
there are a few things that can answer that question for us. What is the condition of the existing pump? How old is it? Can the impeller even be removed from the shaft without breaking it?

Basically to change the motor bearings you must remove the 10-16 screws on the wet end.
Remove the cap you just unscrewed.
remove the small 1" round shaft cap at the rear of the MOTOR. (on the electrical end) this should come out with just a flathead screwdriver. (if it bends a little its no big deal.)
Lock onto the shaft end we just uncovered with a LARGE flathead screwdriver.
While locked onto the shaft, turn the impeller counterclockwise until removed.
Note: some impellers have a set screw in the center of the impeller.If you have one, it is reverse thread and must be removed by turning clockwise.)

If you are unable to get the impeller off of the shaft, you might as well buy a whole new pump. These pumps are a few hundred dollars, but if you have to purchase a new motor, a new impeller, and a new shaft seal at the very least, then the cost is right up there with a new pump.

If you can remove the impeller, keep reading.
Next remove the (4) - 1/4" hex through bolts located on the motor at the electrical end.
With the impeller removed and the through bolts removed, the wet end should now seperate from the motor.
To remove the bearings, we must seperate the front faceplate from the motor housing by taking a large flathead screwdriver to the small flat notch in between the plate and the motor housing. Pry in small even incriments all the way around the plate to remove this safely.

Once this is done, the bearing can be removed. For this we need a good quality bearing puller (these can be expensive and if you dont own one this is another reason to buy a new pump.)
Lock the 2 arms of the bearing puller around the outside of the bearing, and lock the center pin on the shaft and turn clockwise to remove.

When installing the new bearing, use a piece of 3/4" metal electrical conduit about 6-8 inches inlegth.
Place the bearing on the shaft and fit the electrical conduit on top of it, making sure to only apply pressure to the RACE of the bearing (the inside track) tap lightly until the new bearing is in place.

Once this is done, reverse these instructions to reassemble.

Need to change out bearings

You will need a 7/16 inch open ended wrench, a bearing puller, a phillips screwriver, a 12" peice of metal electrical conduit, and the bearings.
dismantle wet end of pump down to the impeller. Remove the shaft cap at the back of the motor(small circular cap in back). use 7/16" wrench to hold the shaft under the cap whiile spinning the impeller counter clockwise untill impeller is off. using a 1/4" hex driver remove the 4 through bolt located at the rear of the motor. seperate end caps on motor housing to access the bearings. use puller to remove. use the 3/4" conduit to tap new bearing into place. Reassemble unit.

Make sure you have an o-ring kit for this pump first

How to seperate pump from motor

Disconnect all power. Remove the six bolts holding the seal plate to the wet end. Remove the two small allen screws to remove the diffuser. Remove the dust cap from the end of the motor and secure the shaft from moving. If installed, remove the Phillips head screw in the center of the impeller by turning clockwise (left hand threads). You can now remove the impeller by turning counter clockwise, note that you may need an impeller wrench to remove it and a specific tool to hold the shaft while you remove the impeller. Once the impeller is off you can remove the four bolts that hold the motor to the seal plate. This process just needs to be reversed to re-install but you will need a new shaft seal (PS-1000).

I have a diamond pump modlel # 560549 i am trying to take it apart but i cant seem to get the pump seperated from the motor.

Of course you can't get it separated especially if the pump housing is still intact. Please do this;
1. Open the screw or bolts holding the front pump
2. Now, you can see the rotating part of the pump,
that is the impeller, and the cover called the
3. Take the impeller cover off, and see if the impeller
is mounted and locked by a nut at the pump shaft.
Or, screwed to the pump.
4. Take the impeller off from the shaft by taking off
the nut or unscrewing it counter clockwise.
5. Take the mechanical seal at the back of the
impeller off from the shaft.
6. Now, you can separate the motor from the pump.
Hope this will help you.

I have a proline 2hp above ground pump. A snake

The impeller is still jammed you need to get it cleaned out. You can try with a pair of needle knose pliers if that doesnt work your gona have to remove the pump bolts that hold the motore to the pump pod. Remove the bolts around the motor and seperate it this will give you better axcess to the impeller. Clean it out and try to move it if the impeller will not spin freely with the debris removed the motor has burned up .

Removal and installation of diffuser and impeller kit

All jucuzzi pumps are some of the most difficult to repair.Pump front should seperate from body(volute) of pump by means of screws, or some kind of band. Diffuser should have ss screws, or
be held in plsce by notches or both. Impellor spins counter clockwise to come off. Can only remove impellor with impellor wrench, or very strong hand. Rear of motor must be held in place with normally a 7-16 wrench, allen head wrench or screwdriver. Depends on manufacturer of motor. Then impellor can be removed!
Should replace shaft seal under impellor. Can seperate body of pump from motor by turning four outer bolts on back of motor. Must mark rear cover of motor so lines up exact for reassebly. Ussually 1/4 inch socket wrench.Seal can be pushed out from back to front with the corrrect size socket and a very light hammer.
Try to factory Jacuzzi seal, they are better than aftermarket.
Coat rubber on seal with light silicone, and press back into place without touching or marring seal face. Best way is use other half of seal (spring piece) to gently but firmly reseat seal. Examine body from rear to make sure seal seats. Reassemble as taken apart, or just take to a qualified service tech at a well established pool/spa place. Kirk
