Re: Wiper Motor leaks at seal

Well, it doesn't work, but I am not finding a leak. I have a couple of questions.

First, just how easy should the paddle move back and forth?

Second, I decided to put my new-fangled, lung-powered vacuum to it by connecting a hose to the vacuum lead. Here's what I note... I note that the little rubber cap that has air slots and moves back and forth with the bendix-controlled gear stays on when in closed position and I am sucking air. So, I am definitely pulling a vacuum. I just don't know how strong. I also note that when the paddle is in either extreme position (i.e. extreme right or extreme left) and I begin sucking air, the paddle will swing a smidge - but only a smidge and then it stops.

So, I am wondering whether my lungs can pull 19 psi like my car, and I am also wondering whether there is undue resistance which prevents the paddle from swinging. My guess is that the paddle is probably swinging fine, as the wiper gear to which it attaches is very resistant to swinging freely, due to the fact that it drives the blades from a fulcrum all the way to one side of the lever.

Any other good way to test?
