In looking for shimmy dampener replacement options for a 182E it seems that neither the Lord option or the McFarlane option will fit. There is a compatibility gap with both of those companies as far as new shimmy dampeners are concerned with the 182E through 182J (1962 - 1966) where it seems there are no options.

Are there any other options available for the 182E?

thx

There are things so worn out that no kit will fix them. I suspect that's the case here. Shimmy dampers get some awesome workouts, and their mountings are light and get torn up. The mounting is also far off center to the shaft axis, putting a bending load on the shaft and radial wear on the cylinder and head bearing bores. Nothing lasts forever, not even the stuff on a mid-'60s 182. Doesn't matter how much you paid for the airplane.
 
What's needed is a slightly oversize and probably also slightly oblong bushing replacement for the shimmy damper-fuselage interface. PMA'd and STC'd of course:rolleyes:

Yes. all the o-rings were replaced a few weeks ago but it is leaking already. I’m hoping maybe one of them got damaged upon reassembly so I’ll give it one more chance but as others have noted it may simply be worn out.
 
Reviving an old thread because I’m having this same issue with my 66J model.

Has anyone found a solution to this problem? The McFarlane PMA part isn’t finished yet, Textron has one for sale for $8,000, and the usual salvage sites don’t show any available replacements.

Any leads appreciated! I’m AOG.

Is this the little shimmy that lasts a few seconds between 25-35 mph (or whatever) or far more serious?

I guess it never occurred to me that it’ll eventually turn into a big dollar problem
 
It killed my wheel pant. I’d call it a severe shimmy. All other points look to be within spec and we’ve tried rebuilding the dampener once, but it didn’t hold.
 
Thanks Dan - I'll have them look into that as well once I find a replacement part, but at the moment it seems that the holdup is that the part on the plane is no longer serviceable and is beyond rebuilding.
 
Just updating this for anyone coming from Google: as of this week, McFarlane has submitted their PMA part to the FAA for approval but it hasn’t come back yet.

I was able to find an as removed replacement with sheared off rod ends, but the specific part I needed was the outside cylinder so we’re rebuilding with the good parts we have from mine and the good parts from the salvage part.

Guard your shimmy dampeners on those early wide body skylanes!

There are MANY part on old airplanes that are pretty much unobtainium. For instance, those flat steel-leaf main gear legs are prone to corrosion, especially on the underside and under the clamped-on step, and corrosion pits eventually lead to cracking and failure. Those legs haven't been made for a very long time, like 50 years or more.
