Default RV-14 Jack Points

I have been jacking via the tie down using the vans method of 2x4s stacked with a bottle jack cup and ball arrangement. It works pretty well but it will get side loaded a little bit as load is taken on and off the gear. This works fine for maintenance at home. I need to come up with a solid plan or product to jack via the gear leg or axle if I am away from base. I don't want to carry a jack. I want to be able to use a standard scissor or car jack I can find at any airport. What are people using?

Works perfect!

I had to slightly enlarge the wheel pant bracket.

I believe that will only work on the 14a version. You can kind of use a jack on the bottom of the -14 gear but its not an ideal setup.

Default rV14 jack points

Your correct, our Jackpoints for the RV14s only works on the 14A gear. As soon as we can physically get to see a 14 gear assembly we will be able to create a jackpoint.
Anyone in the San Diego area building a 14 and willing to let us prototype our concept would be greatly appreciated.

Default RV-14A, RV-12, RV-8 Jack Points

Since we're talking Jack Points...we developed a slick little jack-point that does double duty as a wheel fairing bracket mount. Just toss the bolt & nut in your travel bag and you're good to go. Works with scissor jack or a floor jack.

These were developed for RV-8 but will also work on RV-12, RV-14A, and even non-RV types like Sonerai or Ranger that use flat landing gear with the Type I axle. Affordably priced, too - fify bucks for what you see in the pic.

You can jack RV-14 using a short length of 3/4" to 13/16" round steel bar inserted into the U-1421 axle fitting.

Ken, those look nice, do they have the exact same spacing from the gear leg to the wheel fairing bracket as the stock RV-14A part? Any modifications required to the bracket? Also curious what size bolt that is? I'm sure you've done the math on it, just wondering how much margin it has for shear & bending loads since those loads are applied to the threaded portion which is not nearly as strong as the shank...are there even published numbers for the threaded portion? Could you use a hardware store bolt or does it have to be MS or AN?

Also when you have a wheel and brakes installed, is it possible to get a floor jack up close enough to the bolt head with the jack aligned such that the handle is pointing forward (towards wing LE) instead of straight inboard (beneath the fuselage) as shown on the picture on your website? Would be a bit of a pain to operate the jack from directly under the center of the fuselage...

Default For my -14…

For my RV-14 I had a machine shop make me a jack pad that I can slide into the gear boss. I can then use any jack that fits under the pad to raise the wheel.

Hi Jeff,

What is the apparatus behind the 2 jack pads in your picture?

Also I have seen others just use a solid piece of round aluminum stock without any pad welded onto it. It works well with a standard floor jack, is light and can be carried with the aircraft if travelling.

You have reminded me to get mine.
