Question about Hayward 1.5 Hp Northstar High Performance Pump

1 Answer

Removed lock ring between motor and pump housing. I cannot separate the two assemblies by pulling or carefully prying them apart. I even have the full assembly on my work bench. I do not see of feel any obstructions in the impeller area but the access is small. What am I doing wrong?

If it will run turn the pump on and the water pressure will pop it apart. Other than that a lot of foul language will help but pull and trar and tug is it.

    This will be very hard to pull apart. The "O" ring on the inside around the widest part of the pump is dry and will make it very hard to seperate the halves of the pump.
    Like I saw if it runs you can hook it up and start the pump, if not it will just be a lot of work, this "O" ring I speak of is about two inches back. You will find even after it's apart and you can lube the"O" ring it will still be hard to put back together. This is the reason I don't sell these or Jandy pumps. They are very impressive in performence but the last one I took apart took more than an hour and a half to get apart. Good luck.

How do you remove the fuel pump out of a 2000 land rover freelander 1.8 xei


pry gently or tap it lightly. The lock ring you removed kind of pushes it down tight against a rubber o-ring, about 4 inches in diameter .-the sealing gasket for the pump assembly. They get a little stuck after time. Don't reef on it. Clean it real good first, so no dirt falls in when you pull the assembly out, then tap it loose. Be very careful withdrawing it if the fuel gauge sender unit is attached to the pump.

Fig. Fig. 16: Removing the seal from the housing using a suitable prying tool

  1. Remove the cotter pin, lockwasher and spring washer from the front axle ends.
  2. Have a helper apply the service brakes and loosen the front axle hub retaining nut.
  3. Raise and support the front of the vehicle on jackstands.
  4. Remove the hub nut, washer and wheel assembly. Drain transaxle fluid.

The speedometer drive pinion must be removed from the transaxle housing before the right side drive axle can be removed. Remove the retaining bolts and lift the pinion with cable connected from the housing.
  1. Remove the clamp bolt that secures the ball joint stud with the steering knuckle.
  2. Separate the ball joint from the knuckle by prying downward against the knuckle connecting point and the control arm. Take care not to damage the rubber boot.
  3. Separate the outer CV-joint (Constant Velocity) splines from the steering knuckle hub by holding the CV housing and pushing the knuckle out and away. If resistance is encountered, use a brass drift and hammer to gently tap the outer hub end of the axle. Do not pry on the outer wear sleeve of the CV-joint.
  4. After the outboard end of the drive axle has been removed from the steering knuckle, support the assembly and pull outward on the inner CV-joint housing to remove the assembly from the transaxle.


WARNING Do not pull on the shaft or the assembly will disconnect. Pull only on the inner CV-joint housing.
  1. Remove the halfshaft from under the vehicle and service as necessary.

To install:
  1. When installing the halfshaft, hold the inner joint assembly by its housing, align and guide the shaft into the transaxle or intermediate shaft assembly.
  2. Lubricate the outer wear sleeve and seal with multi-purpose grease. Push the steering knuckle outward and install the splined outer shaft into the drive hub.
  3. Install the steering knuckle assembly. Tighten the ball joint clamp bolt to 70 ft. lbs. (95 Nm). Tighten the hub nut (splined shaft nut) to 180 ft. lbs. (250 Nm). Refill the transaxle with the proper lubrication fluid.

If after installing the axle assembly, the inboard boot appears collapsed, vent the boot by inserting a thin round rod between the boot and the shaft. Massage the boot until is expands. Install a new clamp to prevent dirt from entering the boot.

Just trying to take the plastic covering off of the motor without breaking the plastic controls off


The speed control knob will pry off with a thin screwdriver. Once you have removed it, you will see that the knob for the oscillating feature is split where it slides over its shaft. I took a jeweler's screwdriver and separated the halves slightly and the knob pulled free. It's made that way so it doesn't pull off when you go to turn on/off the oscillation. If you're going to oil the rear of the motor, be really careful when you remove the rear housing and separate the motor sections. The winding wires are tiny andfragile. Only take it apart as far as necessary and be careful reassembling the unit. Hope this helps...!

Remove impeller housing cover. Insert screwdriver carefully into back of motor to keep the armature from turning then unscrew impeller clockwise or opposite the direction of operation. Replace seal on impeller and pump housing. Lube seal with graphite. Replace impeller and housing cover. Remove screwdriver from motor. You should be good to go.

How to dismantle a jacuzzi magnum pool filter pump 1228


When you go to loosten the lock ring you will need to find the lock tab that will keep it from comming off. This tab I think will pull out but it may push in and this will free the ring to turn. Once this is off if the motor runs turn it on for a second and let it push the front and back half apart. If it won't run you can use a flush bag to pressure it off. In worst case you can pry the halvs apart with a big screwdriver. If you do this be careful not to hurt the case of the pump it is just plastic.
When the pump is opener you remove the difusser and look inside the impeller. If you have a screw in the center of the impeller it will be a left hand thread so to remove you will turn it clockwise. Now just unscrew the impeller turning it counter clockwise and take the rear plate off the motor by removing the four bolts on the back. Good luck.

  1. With the engine turned OFF , relieve the fuel pressure at the pressure regulator. Refer to the fuel relief procedure in this section.
  2. Disconnect the negative battery cable.
  3. Raise and support the rear of the vehicle on jackstands.
  4. Drain the fuel tank, then remove it.
  5. Using a hammer and a drift punch, drive the fuel lever sending device and pump assembly locking ring (located on top of the fuel tank) counterclockwise. Lift the assembly from the tank and remove the pump from the fuel lever sending device.
  6. Pull the pump up into the attaching hose while pulling it outward away from the bottom support. Be careful not to damage the rubber insulator and strainer during removal. After the pump assembly is clear of the bottom support, pull it out of the rubber connector.
  1. Connect the fuel pump to the hose.

Be careful that you don't fold or twist the strainer when installing the sending unit, or you'll restrict fuel flow.
  1. Install a new O-ring on the pump assembly and then position them into the fuel tank.
  2. Turn the locking ring clockwise until its tight.
  3. Install the fuel tank and connect the battery cable.
If you dont feel like dropping the tank and hassling with the hangers because they often break cut a hole in the bed of your truck over the tank where the fuel pump is but be careful not to hit the wires. dont cut the piece out completely cut it so you can pry it up to oneside

I have a Hayward Northstar 2HP pool pump. I need


If the motor still runs at all start the pump with the lock off and it will pop out. If not use some liquid soap and a small straw like a capalery tube on wd. Any thing small enough to fit through the space you can get when you pull the seal plate back, their is an inner plate with an "O" ring and you need to get the soap to that then let it sit for half hour or so and go back to the side to side prying when the soap and the "O" ring come together it will slide right out.

Pump disassembly


I removed the impeller on my DW761UQB. The instructions were molded into the plastic pump housing. This is how I DID MINE: Remove motor mount screws. Remove the chopper screw (screw only goes into impeller, not motor shaft). Remove chopper and rotate/remove strainer. Place socket or wrench on impeller tip and place another wrench on rear of motor's plastic fan. Unscrew fan from impeller shaft ( threads are LEFT handed, turn CW). Once fan is 'backed off' of the impeller, CAREFULLY pry the motor/fan from pump housing (impeller is attached to motor shaft via splines). Don't crack the delicate plastic pump housing. Mine was stuck, but separated with moderate force. Now remove the impeller/seals from the pump housing. This worked for MY above mentioned model, I don't know what other models it applies to. I am not a pro.

Can't remove casing for B&D Cordelss Grasshog (NST2018 Type 2)


These are the steps to open the clamshell/motor housing for the Black and Decker 18V Cordless Trimmer Model NST2018. The orange clamshell has two plastic clips that engage two recesses inside the black plastic ring. You use two screwdrivers to disengage the clips and seperate the black plastic ring from the orange clamshell. Follow these steps: Wrap tube assembly in a small towel and mount in a large bench vice securely. You will notice two small openings at the top of the black plastic ring at the top of the orange clamshell. The next steps require two people. Person one inserts a flat-bladed screwdriver into into each of the small openings at the top of the black plastic ring (two screwdrivers). Using the tube assembly for leverage, pry the black plastic ring from the orange clamshell with enough force to disengage the orange plastic clips from the black plastic ring. Person two pulls the orange clamshell/motor housing away from the black plastic ring/tube assembly along a straight line (same axis as the tube assembly). After you've separated the motor/clamshell housing from the black plastic ring, remove the six screws and open the clamshells.
