Default 12 volt sprayer pump

I have an atv spot sprayer I got about 4 years ago. It has nor seen
alot of use. My dad was using it and he said it quit spraying. I looked
at it. When you put 12 volts to it it might turn an 1/8 inch and
releases when voltage is removed.

I took the cover off. There are two magnets on the end. Two springs
came out of it. I dont know where these springs go. Now it wont move at
all.

How can I tell what is wrong with it?

One thing I also noticed is the pump body got very hot when I was
working on it when applying 12 volts.

Its going to get hot if your putting power to it and the motor is not
turning......

Are you sure they are magnets and not the carbon brushes? Usually the
magnets are firmly bonded to the motors housing internally and not
removed very easy. If they are at the end opposite of the pump end,
they are probably the carbon brushes. The springs push the carbon
brushes into contact with the commutator on the armature, and should
be held in a holder that is normally built in the end bell of the
motor.

How do i tell why the motor is not turnign?

You are right these look like little magnets. The hot wire is attached
to them. How then do you pit the springs on and still close the cover?

Sounds like it's not turning because the brushes are out of it. No way
to tell you how to put them back inwithout seeing the end of the
motor, but sometimes there will be a liitle hole you can slide a paper
clip wire into to hold them in place during assembly.

Once you get them back in, check to see if anything is lodged in the
pump itself.

Check the pump side. It is probably locked up due to not being completly
cleaned after last use or it is just stuck because of the close clearences.

Open the pump chamber and free the rotor.
