M818 Wiper control valve - Source?

[rhinob]

This valve is not cooperating. Does anyone out there have a source for one?

Thanks much!

How's it not cooperating?

Mine is very touchy and likes to leak air and spray oil/water all over the place. Wondering if mine is also not cooperating and I just never realized it.

It won't flow at all. No matter where the knob is set.

I'm tempted to disassemble it, but I don't want to pile a bunch of time into it if I can simply replace it. I'm happy to overhaul the thing if they're not available.

any surplus ppl will have it and prob a dozen ppl on here. an ad in the wanted section may be the proper way to get one.

 

[rhinob]

I'll give it a whirl, thanks.

[rhinob]

When you take it apart, take some photos for us newbies. Mine seems to have one speed all or nothing

Sure thing. Will do.

Make sure you take the air line fitting off first. the one opposite the control knob as there is a valve screw that is the control for the air in. If not you will brake it then you will have to get a new one.

Ok, thanks for the info.

I've rebuilt mine before. It's not hard as long as you don't force anything. I'll post pictures of it disassembled tonight.

 

[rhinob]

Excellent news. Certainly taking the guess-work out of it!

First remove the cap by loosening the two set crews. Then, while gently turning the knob clockwise, loosen the small screw in the hole on the opposite end. When that screw is loose the knob will screw out easily. When it's free, push down on the knob and pull out the pin from the shaft. Pull it all apart, clean it, oil it, and put locktite on the backside screw before reassembling. Don't bottom out the small screw, just turn it in about five times. That should fix any problems.

Excellent directions. Repair went without a hitch and is functioning as advertised. A little Molykote 55M grease helped with the sealing cup friction.

Mucho thankso TX!
