I am going to rebuild the shimmy dampener, what supplier(s) sell a good rebuild kit? Anyone using the Lord shimmy dampeners?

I have installed a few Lord shimmy dampeners and they are very nice but very expensive. Technically you cannot rebuild your shimmy dampener, you can overhaul it. In the Feds eyes only the manufacturer can "rebuild". I have not seen kits, there are three o-rings in the later dampeners, two small o-rings that seal the piston shaft, 2 ea P/N AN6227B6 (MS28775-011) and 1ea either AN6227B20 (MS28775-215) or AN6227B18 (MS28775-213) at the head cap. The larger o-ring difference in size is dependant on the dampener part number which is dependant on the year model/ S/N of your airplane. The o-rings should not cost more than $5. Hope this helps...

Thanks Tom.
I ordered an o-ring kit for the shimmy dampener through McFarlane. I ordered the torque link overhaul kit as there seems to be quite of bit of play at the bolts/bushings plus a nose strut seal kit. After flying each flight, there is always a black smear on the strut tube. I clean it up each time and seems to be getting worse. My mechanic will over-see the work on dampener and torque link, but I'll only assist him on the nose strut work.
If the dampener continues to be an issue, I'll try the Lord dampener out. The cost will save on wear and tear on other components from shaking of the nose wheel may bring about, no leaks, and peace of mind.

I have the Lord on mine too. Yes it's expensive but it's worth it.

tag, while you have the nose strut apart, you may want to check the steering collar shimming. Over the years I have found that most of the Cessna shimmy problems can be attributed to a sloppy steering collar. The strut has to be completely removed to adjust the shims.

I'll have my mechanic look into it when we have it apart. Thanks, tag

Thanks for specs on o-rings, steering collar info. Shimmy damper overhaul and steering collar shims are a place to start.
