New Shimmy Dampners

Re: New Shimmy Dampners

In addition to the other things that can cause the shimmy(see Lawrence's comments) - rebuild your current damper. Pretty easy to do. We are all interested in new ones since some of the originals are 30+ years old and have been rebuilt many times.

I am starting to experience a growing shimmy. I would definitely take one as well. What do I do in the meantime? What is the best way to address this problem?

Thanks,

Before going to the expense of changing your Shimmy Dampner there are some other things that will cause shimmy which re not related.

I had a severe shimmy develop last year which was caused by a combination of a worn and overinflated nose tyre and a loose torque link on the nose gear.

New tyre and a torque link rebuild kit cured it for about £150 ($240)

Worth checking, especially the tyre pressure.

Good point, Lawrence. Overinflation of the Nose Gear tire (tyre!) is not unusual. I recall at least 2 other instances posted here where just getting the pressure right cured the shimmy. Nice when life is that simple.

I need a new shimmy dampner....
 
Re: New Shimmy Dampners

Thanks for your help! I'll try the torque link and air pressure first. I think all my tires are a little low..

Re: New Shimmy Dampners

Does anyone know where do get the bushings for the scissors upper and lower bolts?
 
Re: New Shimmy Dampners

My understanding is they are very common and I had mine changed but I do not remember where they came from. I will look for the invoice and if I can find I will post the info.
I also had the bushings replaced in the nose pin and my AP/IA had no trouble getting them.

Re: New Shimmy Dampners

That can't be Gary. Welcome back. Missed our GLCOG get together. Say hello to Karen.
 
Re: New Shimmy Dampners

We definitely need a GLCOG get together. We have a bunch of new guys, too.
 
Re: New Shimmy Dampners

Thanks fellas!

Scott,
6RC is down for annual for at least 2 weeks. Hopefully the wx will improve by then. I lost all of my COG email contact information a few weeks ago when my computer crashed, so we'll have to post any future GLCOG gathering on the webboard.

Later,
gm

Re: New Shimmy Dampners

Hi Byrne,

Sorry, not in May.

Given the time and $ sink of the elevator situation, I probably won't have the dampners engineered and approved till late this year.

If the Cape is not set up to do a thorough rebuild of your old one, have them pull and send it to me, $250. Also. your nose gear should be checked for any loose joints that may be the root cause.

Jim
