M101A2 Tongue Jack Shortening

[thisbenguy]

Has anyone shortened their retractable tongue jack, or disassembled one so I could see if it’s possible.

I will be removing the hydraulic system and mounted a channeled lunette ring to the front, lowering the ring several inches. My goal is be able to open the back gate on my Jeep, at least part way.

I mocked everything up today and it doesn’t look as though there will be enough clearance for the tongue jack to rotate down fully.

I know some have replaced with aftermarket jacks, but I am a big fan of the oem version and changing it would be a last resort.

Has anyone shortened it before or taken it apart so i could see if it possible. Thanks.

There are several different jacks. Post a picture. And the NSN and Part #.

How much work do you want to put into it and how much shorter are you talking about? If you disassemble the jack, you will probably have to shorten the outside tube, the inside tube and the screw that moves it up and down. If you don't mind the fab work, it can be done.

I figured I would have to shorten the exterior sleeve, the interior portion, and whatever screw mechanism is inside. There is probably a bearing a the bottom that the screw or whatever ever rotates in inside. I’d imagine taking a few inches off of each would work.

The TMs didn’t have an exploded diagram, so I was hoping someone had disassembled one for repair.

Its a Pluck and chuck item. No need for stocking parts or exploded diagram. I have fixed several, but wasn't worth my time, at the end.
