Having problems here. It started leaking as i was warming it up for the first time this year. can anyone give me suggestions on how to fix it or what is wrong? It is not a bad leak but it is noticable.

Looks like the seal gone replacement from skidim easy fix, check the bearing while your at it, probably worth changing while stripped down.

You can get a "long" impeller kit which comes with what you need to rebuild your pump.

you guys are life savers, going to order the kit, and get this done. I do not need engine problems from me not doing things needed.

Just took off raw water pump. Getting ready to change out the seals........

Good luck! Here's hoping it's a quick fix.

Just be careful with that little seal .. the 1st time I did that job I wrecked the seal putting it in ..... you should be fine .... and the drip will stop.

Did this over we weekend. The impeller too a while to pull out, probably because i hadn't changed it in 7 or so years. It was in perfect shape surprisingly. The seal is seated pretty flush in its little pocket and i couldn't figure out how to pull it out with NN pliers. I ended up taking a long wood screw, screwing it lightly into the seal, then pulling out the screw with the seal attached to it, worked like a charm, pushed the new seal in, new impeller, new gasket and boom, no more leak whatsoever. Was so pumped i went ahead and fixed my ballast system too!

Dragging up this old thread...
I'm going to try replacing the seal on my water pump, but I've got a question about the copper/brass washer. Where does that go? When I first opened up the pump, it was between the impeller and cover plate, but had slid around quite a bit. I'm thinking maybe it's supposed to slide down the impeller shaft, then the impeller goes over it. Can anyone confirm?

Brass washer goes between the impeller and the housing. Slid the washer on first then the impeller. Look at the pdf on the link in this post. Reassembly is on page 5.

got it, thanks! Makes me wonder if that will cure the leak. Although I doubt it. Think I might hook it up to the hose tomorrow and see what happens. *crosses fingers*
Thanks again!!

If you replaced the seal it should. I believe some have the brass washer and some don't.

Next challenge is going to be getting the seal out. I pulled the Allen mounting bolt yesterday but couldn't get the pump off the pulley. Granted, I didn't go nuts with trying to get it off, but I'm hoping I can pull the seal without pulling the pump apart. Going to try the woodscrew technique in post 9. With any luck, that will work and I can get this done in a reasonable amount of time. :)

I'm in the process of changing mine guys and I don't see the brass washer in there. Is it ok to not have one or should I make sure to put one in with the new seal?

Some don't have it (mine don't) so I don't think you should have a problem!
