Sticking yoke
When doing steep turns, I noticed that there is a little resistance to pitch
changes on the yoke. It seems it binds a little in the bearing through the panel. Does anyone have a suggestion for the type of lubricant I could use on this? Do they make anything for this purpose? |

If its really sticking you need to have it looked at. Its not likely a
lube issue, its probably an issue with something mechanical (bell crank, etc). My Mooney requires 100 hr control tubes lube. When controls need lube they certainly do not stick, they just feel "heavier" in general. -Robert |

A shot of silicone spray on the yoke shafts every 10 - 20 hours will keep everything nice and loose. -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

At the risk of disagreeing with Jay, I would not use a silicone spray. The
carrier for the silicone oil has destroyed more plastic than I care to tell. I used silicone spray on the heater control levers on my car when they started binding. Worked great, until all of the levers broke off within a week of each other. Used it on plastic ski boots. Looked great and the snow didn't stick. I dropped one onto concrete and it shattered into several pieces. My control yoke goes through a plastic bushing. Personally, I don't use silicone spray on anything other than metal. I would try dry graphite, if the bearing is black, or talcum powder, if the bearing is white and completely free of oil or grease. If you use the silicone and the shaft moves through a plastic bearing, spray it on the metal and let the carrier evaporate before sliding it back and forth.

The carrier for the silicone oil has destroyed more plastic than I care to tell. Interesting -- I've never heard that before. Having your yoke come off in your hands could ruin your whole day. Anyone else experienced this nasty side effect of silicone sprays? -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

I have used a teflon spray. But it may have the same carrier characterists.

Probably don't use an oil based lube. It may cause the bushing in there
to swell. I use a clear synthetic grease, then wipe off excess after working it around lots. A silicone lube should be okay too. soxinbox wrote: When doing steep turns, I noticed that there is a little resistance to pitch changes on the yoke.

Does anyone have a suggestion for the type of lubricant I could use on this? Do they make anything for this purpose? My yoke goes through a plastic-like bushing and the co-pilot side squeaked like heck. It was loud, sharp and would rattle my teeth. I asked my mechanic if I could just give it a shot of WD40 or silicone spray. He said not to use any liquid-like spray. Not because it destroyed plastic, but because it would attract dirt and get all sticky and gummed up eventually. He recommended graphite powder. I tried the graphite and it didn't work. Frustrated, I sprayed WD40 in there and haven't heard a peep since. I will now have to keep an eye on the bushing. Kobra |

It's not supposed to be one... You can look at the LPS series, there are various grades. I also have a no-name silicon spray with a KS number, but doubt you can find it easily... -- A host is a host from coast to & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433 |
