SOURCE: Rear drive shaft seal leaking

Yes, but you will need to mark the yoke position and exact number of turns to remove the nut or you will change ring and pinion gear lash setting when re-installing it. You can use a large pipe wrench to hold the yoke still while tightening, or get a special tool made for that.

You should be able to remove the diffuser and then the impeller to gain access to the shaft seal on these pool pumps. Your users manual should have a diagram.

SOURCE: 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.

SOURCE: Hi, I have a waterway executive 48 spa pump and

Thank you for posting your question here on Fixya.com.


Removing the impeller requires you lock the shaft as you turn the impeller off counter-clockwise. You will also need to check for an impeller screw in the center of the impeller inlet. If a screw is present they are usually left hand thread. Back out the screw first, then proceed to remove the impeller.


To lock the impeller you will have to remove the motor end cover or a cap covering the shaft end depending on which version your particular motor has. Look at the end opposite the pump and imagine a shaft from one end to the other right in the center.


Once you remove the cover you will see a slot for a screwdriver, a flat for a wrench, a hex hole for a hex key or some combination of these. Lock the shaft and spin off the impeller. Some are so tight you will end up breaking them in the process. Simply replace it and the seal. Be sure the motor shaft is in good enough condition to allow the new seal to work properly. If too much shaft material has rotted away the new seal will leak soon after it is installed; you would need a new motor at that point.

I thought I had oil leak from prop shaft but upon inspection shaft seals were not leaking but had bit of oil on bottom of casing is there another seal 20hp mercy


Three more seals. One on the shift shaft, another under the water pump and one more at the bottom of the engine on the main drive shaft. There is also a large o - ring on the carrier. Chances are the shift shaft seal is leaking.

Pentair 011523 pump shaft seal is leaking. How do you remove the impeller and motor?


Separate the plumbing portion of the pump from the seal plate which is attached to the motor. The bolts will be a 9/16 inch hex head, that are visible facing the motor. Remove those bolts. That will then allow you to pull the motor and the seal plate away from the plumbing portion of the pump. Remove the diffuser which is covering the impeller, and then the impeller will need to be unthreaded off of the motors shaft. The motors shaft, will need to be locked. You can do this by removing the Cap on the backside of the motor and you can use whatever tool required to keep the shaft from spinning. Once you are able to lock the shaft, you can read the impeller... Note* some styles will have a screw in the middle of the impeller securing it to the motors shaft? This screw is Backwards thread, not normal thread. If your pump has this screw, need to remove it first, then you will be able to unthread the impeller off of the motors shaft.
once the impeller is removed, you can then remove the two halves of the shaft seal. Very carefully reinsert the new shaft seal into the proper places, just the way they were prior to you removing them.

Reassemble in backwards order as you disassembled everything.
good luck

Pump leaking at shaft


That would mean your shaft seals aren't function as they should.
You would need to determine the make and model of your pump to figure out which seal you need.

That should help...

Antifreeze leaks from waterpump after driving


Sounds to me like the shaft seal has failed on your water pump and you need to replace the pump, theres usually a tiny hole either at the bottom of the water pump or at the top of the pump its called the weep hole, when coolant comes out of this hole it means the internal shaft seals of the pump have failed and it requires replacement of the pump, now if the coolant is coming out of where the pump bolts onto the engine block you propbably only need the waterpump to block gasket to fix the leak, check and see exactly where the coolant is coming out from so you can be sure exactly what you need to replace....

How to assemble oil pump 1995 Heritage


Assembling an oil pump is not that difficult provided you do a few things to insure that it works correctly. Now, you didn't tell me if the engine was in the frame or out. The difference is that the oil pump drive shaft will already be in the engine and the assembly will be different than if the shaft is out of the engine.

The first thing is that you want to make sure the oil seal is in the pump body and that it's installed in the correct direction. The lip of the seal must face the feed side of the pump. If you look at the gears and the pump body, you'll see that two gears are "thicker" than the other two. Also, the area that these gears go into are the same, one side it deeper than the other in the pump body. The "thin" gears are the feed gears that pump oil into the engine and the "thick" gears are the scavenge gears that pump the oil out of the engine. Once you get the seal installed correctly. You can start putting the gears and drive keys in.

Start by pulling the drive shaft out the back side to the engine as far as possible and installing the inner oil pump gasket. "Stick" the gasket to the engine case with a thin coating of grease. Slide the driven scavenge gear on the shaft with the drive key installed in the keyway of the shaft. The driven gear is the gear with the keyway cut in it. Lubricate the drive shaft and slide the pump body up to the gears making sure you don't go too far and knock the key out of the shaft.

Now put the drive key for the feed side of the pump in the keyway of the shaft and install the feed side driven gear. Make sure the key does not come out of the keyway. Once you get this installed, put the idle feed gear in the pump body. Then install the snap ring on the pump end of the shaft.

Now, carefully slide the pump towards the engine while holding the oil pump drive gear in place in the cam chest. Slide the pump body up to the engine and loosely install the two short bolts in the pump body holding it to the engine. Turn the pump drive shaft and the drive gear so that the keyways are aligned and use a pair of needle nose pliers to insert the key. Then install the snap ring on that end of the shaft.

Then, "stick" the outer oil pump gasket on the outer face of the oil pump body and install the outer cover of the oil pump. Install the four bolts and snug them up to the cover. Now you are ready to tighten the bolts. You should have the pinion gear and oil pump drive gear removed from the pinion gear of the pinion shaft of the flywheel. This will allow you to turn the oil pump while you torque the bolts.

The oil pump bolts torque to 90-110 INCH pounds. Torque the bolts in a criss cross pattern while turning the drive gear in the cam chest with your fingers. If the pump tightens up at any point, you must loosen and reposition the pump slightly and start tightening the pump again. The goal is to get the pump to final torque and still be able to turn the pump freely. Freely is the key word here. Not herky-jerky turning or having to force the gear to turn.

Good Luck

Drive systems difference


Magnetic Drive: In a magnetic-drive pump, an electrical charge creates a magnetic field that causes the magnet on the impeller to rotate and pump water. Magnetic drive pumps are completely sealed and do not require lubrication. Because they do not contain oil, magnetic drive pumps are safer for ponds with fish as oil leaks do not occur. This type of pump does not generate high head heights, meaning it is unable to lift pond water vertically, which you might need to supply water to a fountain. Work best in cleaner environments with little or no debris Highly efficient, cost-effective operation Since they have no seals to wear out, they require little maintenance Occasionally clean the impeller and its chamber to ensure efficient operation Direct Drive: Direct-drive pumps have an enclosed motor that is powered by electricity, which turns the impeller shaft. Direct-drive pumps achieve significant head height so they tend to work well for fountains or waterfalls. Some models seal the motor in an oil-filled shell with seals around the cord and impeller shaft. These are risky to use if you have a pond stocked with fish as there is an ever-present danger of water contamination if a leak occurs. Many newer pumps, however, feature alternative lubrication over oil that is safe for fish. Look for oil-free models if you house fish or other aquatic life in your water garden. Typically more expensive to operate Ideal pump type for fountains or other accessories Pushes water rather than pulling it Not easily repaired by the user
