NickG Posted November 17, 2024 Report Posted November 17, 2024 OK, SO I’ve had my Ovation since May - its starting to get cold here in Las Vegas and I finally turned my attention to shutting off the Pilot/Copilot knee vents (I believe they’re called Wemac vents). I can’t figure out how to do this. I turn the nozzle but it just turns and doesn’t seem to regulate flow. HELP! Nothing worse than cold lower legs lol.
MikeOH Posted November 17, 2024 Report Posted November 17, 2024 I find that I sometimes need to use my finger to 'help' the vane to move off center, then turning will close the vent. 2

N201MKTurbo Posted November 17, 2024 Report Posted November 17, 2024 Like @201er said, you need to lube it. 1
T. Peterson Posted November 17, 2024 Report Posted November 17, 2024 20 minutes ago, NickG said: Explain? The adjustment mechanism is so stiff that the whole housing is turning. Until you get it lubed, try holding the outer part with one hand and turning the adjustment with the other. At least that’s what I do in my K model when the adjustment is sticky. Maybe an Ovation is different??? 3
PT20J Posted November 17, 2024 Report Posted November 17, 2024 Lubricating might work - for a while. Try to get the lube only on the joint around the knurled knob. If you get it on the ball it will just make matters worse. What happens is that people lube these things and the lube attracts dirt and gums them up. The real solution is to remove them, pull out the retaining spring wire, take them apart and clean the parts really well. BTW it’s the same with the eyeballs where the yoke shaft penetrates the panel. Don’t lube them. 4

Works fine now. 2
ArtVandelay Posted November 17, 2024 Report Posted November 17, 2024 TriflowI used dry silicone spray so it doesn’t attract dirt. 3
Slick Nick Posted November 17, 2024 Report Posted November 17, 2024 (edited) Wemacs are designed to be pushed in when opening or closing. This grabs the "ball" section through friction and allows you to adjust the orfice. Edited November 17, 2024 by Slick Nick 2 1
NickG Posted November 20, 2024 Author Report Posted November 20, 2024 Thanks folks! got 'em to open and close! 3

I tried using WD-40 but that did nothing. I can hold with one hand and turn, but I would like it to work with one hand. I am not familiar with Tri Flow products. Which version of Tri Flow will work with on the wemacs or would any of their lubricants work?

To me, Tri-Flow smells much better than anything else you can use in the cockpit and you can buy small cans. I took mine out, cleaned it on the workbench, wiped off the lubricant and put it back in. Works fine now.
PT20J Posted January 26 Report Posted January 26 They get gummed up when people lube them and then dust gets in the lube. More lube might help for a while, but the real fix it to remove, disassemble and clean them.

I'm specifically thinking of a spray PTFE lube with an alcohol base (TW-25B spray, for gun lubrication). I hear you on the effects of any remnant base liquid (oil, etc).
N201MKTurbo Posted January 26 Report Posted January 26 If they don’t work, just throwing them in a can of solvent, working them till they are free and letting the solvent evaporate will work as good as anything.

They say it is a lubricant, and it is sort of, but it's more of a solvent/lubricant that's great for getting stuck things to move. But over time it will collect dust and gum things up. Tri-Flow (which Mooney calls out for use in a number of places) is a usually a better option.

mooneyflyfast Posted January 26 Report Posted January 26 I just freed mine up. Kroil and a little heat from a heat gun. No longer have to stuff tissue paper in them to keep from freezing. You have to hold the eyeball while turning the knurled part.

0TreeLemur Posted January 27 Report Posted January 27 Following @PT20J's suggestion, I used contact cleaner and a thin rag. Wiped a bunch of gunk out of them. Now they work fine.
Slick Nick Posted January 27 Report Posted January 27 I'm gonna try mine in an ultrasonic cleaner for a bit. Should be able to get all the grot out of there.
