I know bash bash bash bit has anyone tried to run wd40 though the system or silicone spray while they are running?

Did anyone have issues with the 1-7/16" ID o-rings being too big? Mine were too big. Might that have been 1-7/16" OD?

After getting the motor apart that wasn't working it seamed pretty clean. The orings didn't look swollen. However, after some cleaning and reassembly with the original orings, it still doesn't move as easily as the other motor.

I will go back and debur the holes that was mentioned earlier.

Just used this thread to redo my wiper motors. I didn't need to do the bushings but both motors didn't work. I got both working great and used a pack of o rings i got from lowes. There is two different t o rings in it i used the bigger ones. They seemed a tad smaller then the stock o ring but they work great and we're only $2 bucks and change each.

Ive found the problem is rarely the motor, but the fact someone pushed the red button. This unbeknownst to the unknowing, moves a divider valve you cannot see. Often when you pry the red button out your wiper still does not work. This is because the valve did not move back just because you pryed the button out. Remove the end cover, and use a bent paper clip inserted into the small orifice and push the valve back. The red button will be difficult to push again. Re assemble, and voila wiper works.I will try to get around to pics or a seperate post covering this.

This is what's going on with mine it will go to the right but stops , the valve won't move over , tried the paper clip but didn't work so I will take cap off and drill small hole opposite of red button and try that then seal up hole

And by the way don't do that it's a different chamber

Post 28 and 29 combine for some funny stuff. Thanks for the heads up, Rm.

I'll try my hardest with what scorpion said to do cause the red button problem is what is wrong with mine.

thanks

Yep mine just looked like that , but sadly can't get to that sliding valve

Remove the two inner screws to reveal yet another set of vacuum holes. You will have only the outer most portion of the wiper end plate. Vacuum hose end with the oposite side showing about 4 to 5 vacuum passages. The valve is in the end cap this is where the paperclip comes in. 1st spray a little gun oil in the passages then attempt to slide the clip in toward the red button. You may have to start the process at the very far oposite hole and then move to the second hole to finish. Once done and reassembled you will have to hook it up turn it on, then you may have to depress the red button just a bit and the wiper will work. Drilling a hole might work, but I would try every option before going extreme.

By thle bye the only thing that needed to be removed and disassembled was the end cap in the first picture, I disassembled mine on the truck, and only the end cap needed work. Look at the end cap, you will notice it has 2 sets of cork seals . Your pic only shows you have disassembled to the 1st seal, take it down 1 more seal by removing the 2 screws and seperating the second cork seal to reveal the end plate only. You will then be able to use the clip to slide the inner valve toward the red button. Hope I helped.

 

[scorpion6]

I will try to post a full work up with pics and diagrams tomorrow evening if you guys can wait on me.

 

[VPed]

I can wait, it doesn't rain that much out here. Although, the last time it did, I was in the deuce and had to use the manual lever all the way home.

 

[scorpion6]

Here it is guys as asked for in pics easy to see and follow.View attachment 522665View attachment 522664

 

[scorpion6]

So the pics are definetly out of order, but remove the cap, as you can see there are two cork gaskets. This means you then remove the 2 screws and remove the small round cap diverter, then remove and seperate the second cap to reveal the holes. Insert the clip into the holes as pointed to by the phillips. Bend the paperclip the an angle as the diverter holes go down as well as to the side. Insert the clip toward the red button. If it pushes the button all the way out done, if not use the second hole to finish. Put it together in reverse then try. If it does not work keep the wiper on and press the red button slowly untill it works. Should solve the problem. Now if you push too hard you will be back to square one, and its time to do it again. They really should have put a return spring behind the inner valve.

Still lots of questions as always about air wiper motors
This should be a Deuce sticky with those other really good stickies
OR be re-titled so the search engine can find it.
35 minutes of searching for this particular thread but I never used
'plastic" as the lead word so search went everywhere but here.

As far as the cork seals go, you can clean them with a scotch brite pad (be gentle and do not tear them) and breathe some life into them with tru-oil (the stuff used on gun stocks). I heard that soaking them in olive oil over night works as well (have not tried that yet).
