I TAKE THE MOTOR APART AND STICK THE ROTOR IN THE VICE AND USE A LARGE SET OF CHANEL LOCKS TO REMOVE THE IMPELLER. OR YOU MAY BE TALKING ABOUT JUST GETTING THE MOTOR OFF OF THE TANK.. TAKE THE BAND LOSE, USE TWO LARGE FLAT BLADE SCREW DRIVERS TO PRY OUT THE MOTOR ASSY. FROM THE TANK . YOU WILL FIND THAT ITS BETTER TO BRING THE WHOLE PUMP TO LOCAL POOL PUMP REPAIR GUY.. I RATE THIS PUMP ON DIFFICULTY A SOLID 10 .. AND THATS A 1-9 SCALE... WELCOME TO THE HAYWARD NORTHSTAR .. REMEMBER TO VOTE OR COMMENT .. IT IS THE FUEL TO KEEP ME TRYING TO HELP U GUYS .. JAY

Dishwasher leaking from bottom


If you are sure this is not coming from the door, then it is probably leaking from the pump. The motor is outside the dishwasher and the pump is inside. The shaft of the motor has to turn the pump, so there is a seal that the motor shaft goes through. You might be able to replace just the seal, or maybe the whole pump or maybe the whole motor/seal/pump assembly. This can be fixed by a handyperson with some serious skills. Parts are available on-line. But it has to start with a pretty serious dis-assembly. The price you would pay to have this professionally fixed is up there comparable to a new cheap dishwasher. Good luck!

Remove motar from whisper flo pump


Replacing your pool pump motor
Gather the following items.
Phillips and flat head screwdrivers
Circuit tester
Dry towel
Step One
First, make sure that the power to the pump is turned OFF. This means turning off the breaker at the panel box and not just the switch at the pump.
Step Two - Removing the motor assembly
Remove the four hex head bolts which hold the motor assembly to the pump/strainer housing (These bolts may not be visible).
Slide the motor assembly out of the pump/strainer housing, exposing the diffuser. Pull the diffuser of of the seal plate, exposing the impeller. (The diffuser may remain in the pump/strainer housing. To remove, pull it straight out of the strainer housing.)
There will be a gasket or O-ring sealing between the motor mounting bracket and the strainer housing. Inspect this thoroughly and replace if necessary. An economical option would be to purchase a Go-Kit which includes the pump shaft seal and all necessary o-rings, gaskets and lubricant for your pump.
Step Three
Now, you can lift up the motor with bracket attached to get to the wiring more easily. There may be a bare copper ground wire attached to the outside of the motor that you will need to disconnect. Remove the cover plate on the back of the motor to get access to the wiring. You should have one green wire that is the ground wire and two other wires that are your leads. The lead wires should be black and white but could be any other color except green. Disconnect these wires (they may be attached to a screw, held down by a nut, or clipped on with a terminal clip).
Step Four
Next, you will need to disconnect the conduit (sleeve covering wires between motor and switch or junction box). This usually means unscrewing the compression nut that is screwed on the adaptor which is screwed to the motor. After unscrewing the conduit compression nut, you can pull out the wires from the motor. If you wish to reuse the adaptor, unscrew it from the motor.
Step Five
Now you must remove the impeller from the motor. Remove the volute covering the impeller if it is there. (Some are screwed on). You will need to go to the opposite end of the motor and pop off the plate covering the shaft. The shaft will either have a slot in it for a screw driver or is flattened to allow you to put an open end box wrench on it. This will allow you to unscrew the impeller. You will unscrew in the direction that is opposite to the direction that the veins point at the outside of the impeller. This is the same direction that the motor will rotate the impeller. This may look backwards but the water comes into the center of the impeller and rolls off the veins away from the impeller by centrifugal force. As you take the impeller off, be sure to note how the pump seal is positioned. We highly recommend replacing the pump seal with the purchase of a Go-Kit when replacing the motor.
Step Six
Now you can see the bolts that hold the motor mounting bracket to the motor. Unbolt these, separating the motor mounting bracket from the motor. You are ready to reverse the process to install the new motor.
Step Seven
Important Notes on Reassembly: DO NOT touch the ceramic faces of the seal; This may cause the seal to burn up and leak. Be sure to tighten the impeller completely. Be sure to wire the new motor for 110V or 220V depending on what you have. This may be a simple switch in the motor or you may need to use the wiring diagram on the motor to set for the proper voltage. (Black tracer means the white wire with a black line corkscrewing around it.) Be sure to put the volute back on, aligning properly. Be sure to reconnect the bare copper ground wire to the ground lug on the new motor. When tightening bolts, alternate tightening a few turns at a time to seat evenly or the pump may leak. Fill the strainer housing with water before starting the motor to prime system and prevent damage to seal and impeller.
More Helpful information on how to replace a pool motor
Shaft Seal installation
Clean and lubricate the impeller hub shaft and pump housing seal recess with a dilute solution of non-granulated liquid-type soap
Gently wipe the black, polished surface of the spring seal assembly with a clean, soft cotton cloth. Press the spring seal assembly onto the impeller hub with black polished surface facing away from impeller.
Gently wipe the polished face of the ceramic seat with a soft cotton cloth. Lubricate the O-ring on the ceramic seat and press it firmly and evenly into the recess of the seal plate with polished side facing out.
Place the seal plate onto the motor mounting bracket aligning the positioning lug and guide.
Replacing the impeller and diffuser
Slide the motor assembly, with the diffuser in place, into pump/strainer housing, being careful not to dislodge the diffuser.
Fasten assembly to housing using the four bolts. (Be sure housing gasket is in place.) Tighten alternately and evenly

Leaking #1 pump on Arctic Spas Cub hot tub.


I found out that the pump impeller can be unscrewed from the motor shaft by turning the impeller while keeping the shaft from rotating. There is a brass shaft coupling embedded in the back side of the impeller. This allowed me to remove the leaking seal assembly inside the pump by tapping it out gently. However, instead of just replacing the seal, I decided to replace the entire pump with a newer version. Cost was only about $25 more than replacing the seal and gaskets. The pump-motor assembly has been reinstalled in the spa and there are no more leaks.

Leaking hot tub motor


hi! there,
well occassionaly leak on pumps this is due to the mechanical shaft seal has been worn out.If you can do fix your self
try to prepare tools to be used mostly set of socket wrench,set of open and closed wrench,pipe wrench one pair,screw driver flat and cross,switch off circuit breaker of pump motor,disconnect elctrical wiring of pump motor,disconnect pump pipe fitting usually on union service fiiting, if pump is free from fitting loosen bolt on pump motor base,pull out pump motor place on a particular working table,have a prepare box to place all bolt to be disconnected on pumps,we have to pull out motor from pumps housing assemblyd217218.jpg
have you seen hydro pump,the motor assembly was couple to pums assembly.thereare 4 long bolts connected holding motor to pump assembly at the back of motor loosen this to disengage
motor and pump assembly,try to put mark on motor back cover
for reference in putting back.if motor is disengage on pump assembly, of course the rotor of motor still connected on pump assembly.

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

Error code 59.c0 in HPLaserjet 5550


This means a printer motor error has occured. From the service manual: C developing disengaging motor rotation error.

To fix:

Developing disengaging motor
error
1 Reconnect the connectors J16 for the developing disengaging motor and J1100 for the DC controller PCB.
2 Replace the developing disengaging drive assembly.
3 Replace the DC controller PCB. Calibrate the printer after replacing the DC controller.

So, at the very least you'll need the developing disengaging drive assembly and, if that doesn't fix it, then you'll need the DC controller board. My bet is the DC controller has failed.

Sorry for the bad news, but please rate this solution as fixya even if it wasn't what you wanted to hear. Thanks.

GE 24in GSD980X Dishwasher water leak in pump &motor area


I had the same problem. There is no way of replacing seal/joint between pump and motor. It can't be taken apart w/o destroying parts, it only comes as an assembly. Costs around 130$ for pump/motor assy, so it might not be worth it.

Dishwasher fills w/ water, does not wash, but does drain.


Joel, it's hard to tell whats going on here without the full model number. The number you posted should start with a 665, 363,587 or 464.  Here is a couple of things to look for.  It sounds like you have a seperate drain pump. Remove the bottom toe panel and hopefully there will be a tech sheet behind it.  Check the harness to the motor itself.  You want to verify that there is 120V going to it when the wash motor should be running. If you hear the motor humming and kicking out on the overload, then we can assume you have something stuck in the impeller or the motor is bad itself. The tech sheet will give you a diagram for the hot and nuetral.  Check the float switch inside the tub, it should move freely up and down. This is a safety device to insure the dishwasher does not overfill.  If this is a 665,  there will be a start capacitor on the left side of the wash motor.  If one of the wires came off the cap,  the motor won't run.  Regarding the door switches,  if you have 120V going to the motor during the wash cycle, you can assume the door switches are o.k.   Hope this gets you started in the right direction...Catriver.
