Yet Another Air Wipers Thread

[Jinx]

I searched and couldn't find the answer for this.

Having tested my wipers for the first time yesterday, I noticed a significant amount of air leaking around the gasket on the left side of the passenger wiper motor. After tightening down the 8 or so screws around the gasket, the wiper no longer moves at all, no matter how much I turn up the air pressure. Are these screws supposed to be tight or do they need slack to allow the air to pass?

The only way to get it to work is to loosen the 8 screws around the gasket, but this causes air loss around the gasket and the wiper tends to fall down while I'm driving my deuce. I'm guessing the vent tube (the one that's turned up towards the windshield) is blocked up with dust/dirt since there doesn't seem to be any air coming from it. Does this sound right?

My truck is from the desert. I don't think the wipers were used much if at all.

I would unplug the exaust hole, then it should work. When you stopped the leaky gasket the air had nowhere to go so it wouldn't work.

Stupid question, but is the exhaust hole the bent black tube near the air inlet tube?

Dear Jinx:

The bent back tube on the left hand end of the air wiper is the exhaust. Cover the one up on your working wiper and it will stop too! I suspect some little critters decide to plug up your vent for you, so get the ol' wire out and hop to it!

I tightened up all the screws nice and snug, then turned on the air. Nothing was moving so I jammed a wire down the exhaust tube. Little by little dust and crud blew out of the tube and suddenly the wiper started working extremely fast. A lot faster than the driver's side wiper motor. I did the same thing to the other motor and a bunch of crude came out of that tube as well. Now both wipers work flawlessly! Woot!

Hummm..., wipers that work flawlessly on a Deuce, interesting concept

I ain't believing that they are working "flawlessly" unless I see video.

Okay, there's one minor flaw. The passenger side wiper runs faster than the driver's side. Is the screw above the exhaust tube for adjusting the air pressure? I'd like to synchronize them a bit more.

I could install some kind of adjustable valve in the air hose to the passenger wiper...

So yeah, the driver's side wiper is slower. It still seems to gum up after sitting for awhile. I've taken it apart but couldn't find a blockage. I think I will replace the motor to be on the safe side. I'd hate to get stuck in rain only to find out my wiper has gummed up again.

If it's any consolation my Driver's side wiper runs slower than the passenger side as well. It actually gets painfully slow the longer it runs, though closing and reopening the valve makes it speed up. Kind of repetative always opening and closing the valve.

I use Rain-X inside & out. Follow the directions & do a good job, & you really don't need wipers!

Rain-X is a great idea. Thanks! I will pick some up next payday.
