Wayne irrigation pump repair manual

Have an irrigation pump used to pull lake water that failed last fall. Recently replaced the impeller and seals, put everything back together and the motor shaft turns freely. When power is turned on, the motor hums for a few seconds, does NOT spin on it's own, and then a small puff of smoke accompanies the motor shutting off. Any ideas? Thanks

Utilitech 1 hp lawn pump runs for awhile, then shuts down. After a few minutes, the process repeats. It's pumping water from a lake, but must be overheating. Is it fixable? How do I fix it?

when pumping from a lake you will be pumping uphill
centrifugal pumps are susceptible to over loading because operators do not realize that water has mass and weighs a lot and the pump has to things to contend with
first lifting the water from the lake ( lift height)
the volume of water in the suction pipe will load the motor
now that it successfully lifts that water mas up it now has to push it up hill to a receiving tank of some sort
now distance to that tank ( friction in the pipe ) and height up to the tank inlet ( head pressure and it is measured as the height the discharge pipe is above the pump level --not ground level) have to be considered
unless you are a hydraulic engineer or have the equipment installed by irrigation experts all of this information will be foreign to you and that will result in too small a pump and yes it will overheat and in cases the water in the pump will boil as energy from the impeller of the pump has to go somewhere if the water is not moving
what I am suggesting here is to get pump experts involved to design a proper system with sufficient hp motor and pump volume to do the job

Find replacement impeller for Wayne pump YCB139

some pumps can be fixed if, disassembled properly in the first place. and last for many years. soo that said, search your area for your local electric motor repair shop with free testing, bring it in and see if they might have a used impeller, new shaft seal and the bearings, to get you up and running again. REMEMBER TO PRIME THE PUMP AFTER THE REPAIR ! most all pumps need water in them to work

Jabsco toilet fails to fill

Was the toilet "Winterized" last fall? If so, have you assured that any plug in the clean water intake has been removed? If NOT -- are you sure the pump has not been frozen and internally damaged by ice? The pump is a simple device which rarely fail unless its inlet is blocked, or the pump seals or body are damaged - usually by freezing.

Is amsf-6 a self priming pump??

most all pumps need to be primed the first time before use, and every time after a repair !! you fill up the tank with water (about 3 gallons?)first this gives the pump suction it needs to start pumping IF YOU don't prime it it will burn up the shaft seal (in just a few minutes) and it will be slow to start pumping or leak OR not pump at all. if you ran it dry you will need to replace the shaft seal, you can split the pump at the seal plate leave the plumbing portion hooked up and bring the motor att. to the seal plate to your local pool pump motor repair guy and have him replace the shaft seal ..BEST CHOICE $20 and ask him how 2 take better care of it (priceless )..hope this helps ... jay the pump repair guy in longwood fl

I have a proline 1.5hp pump need to replace the shaft seal. I can't seem to get the plastic impeller off. We use a screwdriver to hold the shaft screw and try to turn the impeller counter clockwise...

Keep trying - It is stuck and will likely break but you have to remove it to change the seal. It is not uncommon to need to replace the impeller when the seal fails since the water gets behind the impeller shaft and rusts the metal causing the impeller to bind. If you still cannot get it free pull the motor thru-bolts and lock the rotor once removed from the motor in a vice. Use a large pair of channel locks to break the impeller free...replace it if necessary.

When I turn on my STA-RITE 1.5 HP pump, it makes a humming sound.

A humming noise is fairly normal if the pump is running and pumping correctly. I am guessing this is not the case. Usually it is just a stuck impeller that is the culprit. Power down the unit and open the pump housing to access the impeller. Then gently turn the impeller feeling for resistance (some resistance is normal from the magnets of the motor). If everything seems ok close and secure the pump housing. Try powering the unit on and see if it starts up correctly. If it is still having issues manually prime the pump. If the pump runs correctly for a few minutes after manually priming but slows or stops you have a leaky seal or fitting to find. Finding the seal is not hard but will take a little time and patience. With your garden hose, very carefully run water over each joint and fitting with the pump running. It will take a minute or so of water running over a leaky seal for the pump to prime so take your time. Make sure not to get water on the motor as it can deliver a very nasty shock and destroy the motor. If none of this gets you up and running the cause may be the motor is bad and needs replacing.

Water pump is leaking on my 2001 Yamaha YZF 426 motorcycle.

First you remove the four 8mm bolt that attach the water pump cover to the side cover, the lowest bolt will drain the coolant. next you remove the coolant pipe with one 8mm bolt. The water pump cover like any part that has been in place for years may need some force to remove and that is why you will find two tabs around the outside of the pump cover for prying it off.

Once you have the cover off the impeller unscrews by way of a built in 10mm nut. This nut is right hand threaded and is removable by rotating it counter clockwise with preferably a 6 point socket as a 12 point socket may round the nut sides since the impeller and built in nut are made of aluminum.

To replace the twin seals (one for water/coolant and one for oil) you must remove the engine side cover from the motor and pull the impeller shaft out from the engine side of the cover. After the shaft has been removed the bearing is pulled out with a bearing puller or sometimes it can be removed by pushing it out from the outside in with a makeshift driver but the bearing can be damaged by this method and it is not recommended. The old seals can now be pulled out or pushed out from the opposite side.

To replace the new seals you must drive them in perpendicular to the impeller shaft with the manufacture markings to the inside. The water seal is installed from the outside and the oils seal from the inside.

There is a tool used for installing the seals called a seal driver but you could make one in a pinch. The seal driver makes contact with the outside diameter of the seal where it is solid and has a metal core. The inside diameter is soft and flexible and should not be used to push the seal in place however it can be used to keep the seal driver centered over the outer diameter and to keep the seal moving in a strait line perpendicular to the impeller shaft.

Once the new seals are in place they should be greased with some lithium soap based grease.

Install the bearing and reassemble the impeller shaft then you are ready to reassemble the engine side cover and water pump housing but make sure you spin the water pump impeller slowly as you install the engine side cover as the impeller shaft is driven off the engine shaft behind it and the shaft needs to be aligned in order for it to fall in place (do not try to force the cover on).

I have a 1/2 hp pump which I use to pump lake water to my irrigation system. The pump takes too long to turn on when the spicket is opened and sometimes too long to shut off when the water spicket is...

when using the spicket you use less flow than your irrigation system so a delay in the pump coming on is normal...otherwise if you are having the same problem when the irrigation is running..a pressure switch adjustment may be necessary...please follow the manufacturer instructions for your pressure switch.
