marinegrunt 1 Report post Posted June 9, 2017 I ordered a rebuild kit for my Karcher pump. The pump has 6 valves. There were 3 that I was able to tap out from the rear. The other 3 i was not so I tried prying up with a pick. What ended up happening is the top half of the valve separated from the bottom. I can tell they're assembled like that there just wasn't enough tightness to pull the while valve out. The round metal base with o-ring is what's still in the pump. Is there a trick or even a special tool to remove it? Seems like maybe a tiny pair of reverse vice grips would work if they even make them. I've considered heating up the brass body a little so it expands some. I don't know if that's a good idea or not. I do all the time on aluminum when replacing bearings. I do have the valves soaking in Kroil for the night hoping it'll lube them up. I posted a picture of the whole valve and the top half of the valve. I also disassembled one so you can see the metal part that won't come out. Any help is appreciated. Share this post Link to post Share on other sites

Larry Adams_8364 7 Report post Posted June 14, 2017 Have you tried soaking in C.L.R.? We had to do that on a pump that we just repaired. The pump had hard water and calcium buildup in it that we couldn't see. Kinda like battery acid on a post. It worked for us... Share this post Link to post Share on other sites
