Painting my gear legs
I am in the process of replacing my landing gear. I was looking for some advise on what kind of primer and paint to use? The legs have been plastic beed stripped of all paint, so I am starting with bare metal.
Thanks for the advise.
Thanks for the advise.
Re: Painting my gear legs
Your first statement is the one that matters most. Cessna does have material available on 'how to" inspect and recertify landing gear.bigrenna wrote:Cessna is pretty strict with how MLG should be treated.
It's good that you blasted them and didn't strip em. Using chem stripper is a big no no due to hydrogen embrittlement. Best thing would be to use a wire wheel and mechanically strip em.
I just refinished mine. I used a two part epoxy prime, then a HD Imron top coat. This is prob the toughest finish you can do.
Of course the nay-sayers will step up, but this is a good time to install the PPonk kit. It's also a perfect time to make some grease plates and get that toe and camber dead nuts on. Not sure if the A/C is level or not, but if it is, you can shim under the MLG Jesus Bolt to get it square.
Good luck!
They are quite specific on how coatings and corrosion are to be handled. If it is to be "receritified" by some one who can it then becomes mandatory to follow those recommendations. You should at least look through the material before going forward.
The corrosion garu's say that metal "Hydrogen embrittlement" only occurs if the removal product remains in place. If it is completely removed it is not a factor. Ref: Corrosiondoctors.org

Re: Painting my gear legs
Thanks for the good advise, my legs have been tested and re certified. I am now getting ready to paint them so I can put the legs on the plane. I do have a pponk kit installed. Bigrenna can you please explain in more detail how you use grease plates to adjust the Toe and Camber of the gear?
Re: Painting my gear legs
The process is described in the Cessna 100 series Service Manual. 2 grease plates are laid on top of each other then slid under each aircraft wheel under load with the aircraft being level like you would have it to do a weight and balance. The gear will rest in a position where you can measure the toe in and camber. It also states that your aircraft should be at gross weight if I remember correctly.

Re: Painting my gear legs
The service manual says ideally it is best to adjust at normal operating weight, not at MGW.

Thanks Karl, I could have sworn it said Max Gross but thanks for double checking. By the way, I have an ASW-20C also. DlowNslow wrote:The service manual says ideally it is best to adjust at normal operating weight, not at MGW.

Great to see there are some other glider guiders in the group, hope to fly in your neck of the woods one of these days.

Re: Painting my gear legs
+1 on the glider pilots comment. If you are in the Tucson area, we have a great club at El Tiro Gliderport.
I also own a 20C.

Re: Painting my gear legs
The factory recommendation is to load the airplane to 2,000 lbs for alignment purposes, but as has been pointed out elsewhere that is not mandatory. Whatever your typical operating wt is should be fine.

Re: Painting my gear legs
I have priced out a two part primer epoxy that including the hardener comes to around 160.00 for a gallon! Just wondering has anyone powder coated gear legs before? It seems like it could be a good option but I am sure there is a good reason not to do it...
Re: Painting my gear legs
I do not believe powder coating is an acceptable practice with spring steel gear legs. Powder coating requires exposure to 400 degree temperatures to cure. I believe that will compromise the molecular structure and integrity of the gear leg. I may be wrong but from what I know, I wouldnt expose the gear leg to that process.Thart739@gmail.com wrote:I have priced out a two part primer epoxy that including the hardener comes to around 160.00 for a gallon!
