How to remove air wiper motors

[Scott & Heather]

I'm still waiting for my rebuild kit to arrive from Luke. Once it comes I'll be carefully rebuilding. I'll let you know how it goes Dave. I sure hope I don't end up with dead wipers

I rebuilt both of mine. Used pipe wrench on outside nuts. Take your time, test fit the pieces, try it mechanically prior to air valve.  Then be careful, slip in the air valve, the bench test.  Take pictures as you take it apart.  Good luck.

I accidentally posted this in Dave's thread...I meant to put it in mine.  

Ok. In Dave's defense, (Tikvah), I very carefully and slowly (this project took most of my day today) took photos of the assembly, and disassembled it. Replaced plungers/o-rings, and air manifold. Put it all back together...and it was jammed up. Same problem he had. The problem is that you can't easily mark the gear/track locations to each other so when you put it back together it's easy to guess and mis-align them. That being said, I'm going to call Dave here in a little bit because I think he posted that he has the gear in the dead center of the track. This isn't correct, I had to pull everything apart all over again and using the photos I took earlier, positioned the lever arms in the "parked" position, and then moved the track to place the gear at one complete side of the housing. This proved to be the issue and I have a wiper that once was completely dead, and now lives! And really operates smoothly...wow...no jerky movements, just smooth and I like that I can slow it down or speed it up with the knob. I'm a believer in air wipers again. Mine are dated 1982, so they are the same age as me...33 years out of a wiper motor ain't too bad in my opinion. Here's some pics of my mess and a video of success!

   I see that the new front assy has brass threaded bushings now. Mine are the old style with small cracks like your's, but not as bad. in the back ground.

If anyone wants my old o-rings and plunger inserts etc, I can send them. You could probably buy o rings locally much cheaper. Between the plastic manifold and the oring and cork gasket kit, I was out $130. That's too much money in my opinion
