Joker_USAF Posted January 31, 2013 Share Posted January 31, 2013 Fellas, looking for some help. Some of you may have seen my Facebook post a few weeks ago concerning getting my 72 Monte through the German inspection. One of the items I failed was the lack of a working washer pump. I have since purchased the pump and installed it yesterday. It worked beautifully the first time I pressed the switch in to get the fluid. Then I noticed that it continued to spray my windshield. It will only stop when I turn the wipers off. Now when I turn them on, it starts spraying again immediately. I took the dust cover off and tried it without...same thing. I took the two prong wire connector off of the pump...same thing. Any ideas as to what is causing the continual shower? Quote Link to comment Share on other sites More sharing options...
montefrazer Posted January 31, 2013 Share Posted January 31, 2013 First place I woud look is the brass strip that is just above the motor. Make sure it's there and not tucked under the washer assembly. It should be clean and have a mounting bolt through it and the washer assembly. Easy to get it under the washer when putting a new one on. Quote Link to comment Share on other sites More sharing options...
Joker_USAF Posted January 31, 2013 Author Share Posted January 31, 2013 The brass strip is where it's supposed to be and I had cleaned it before I put it all back together. Quote Link to comment Share on other sites More sharing options...
Joker_USAF Posted February 8, 2013 Author Share Posted February 8, 2013 Well I figured I would make sure to update this thread so that we could have the info for historical reference. I figured out what was causing the pump to keep squirting. The picture below is the original that I removed. The mechanics work but the pump itself won't hold pressure and so won't suck the fluid from the bottle. The new one worked fine but wouldn't stop spraying. I have fixed it temporarily until I get figure out a permanent solution. Brief summary on how it works: Latch #1 slides back and forth with slide #3 while the wipers are moving. When #1 slides forward it grabs a tooth (circled left) in the wheel and pulls it back. It will continue to do this unless latch #2 gets underneath as it shown in the picture. Now #2 will only be underneath when it reaches the cut out on the side of the wheel (circled center). When it is in this "resting" position, slide #3 will continue to move back and forth but #1 cannot grab a tooth and so the pump will not spray. When you press the wiper switch inside for fluid, it activates the magnet (copper wire) which pulls #1 upward allowing #2 to grab a tooth to start turning the wheel which activates the pump. The wheel will make one rotation until it reaches the cut out (center circle) which will drop #1 back down causing #2 to slide over it. This disengages the wheel and the pump goes back to "rest". My issue on the new one is that when it comes back around, #1 doesn't drop far/fast enough and so it gets pulled back up to the magnet causing the whole cycle to continue again. I can pull it out of the way myself while it is running to stop it. Just figured I would give to this group while I can since I am pretty sure I will spend most of my time taking info. Rob - btw, I passed the German inspection this week. Quote Link to comment Share on other sites More sharing options...
