Hi group,
I have posted pictures of a simple bungee replacement tool in the photo album http://www.j3-cub.com/index.php?option=com_gallery2&Itemid=46&g2_itemId=2479. This tool should work on ALL Piper aircraft with EXTERNAL bungees (J3, J5, PA-11, PA-18, etc.) and I think it works with hydrosorbs if they are installed.
I DID NOT invent, design or build this tool. I had it copied from one a friend had. It is very similar to a tool seen being used in a film of Cub construction in the Piper factory. At one time I DID see a very similar tool being offered for sale, but I don't remember where.
I have seen a number of "medevil torture device" tools built from bumper jacks and engine hoists used to install bungees. THESE THINGS SCARE ME! :shock: This tool is simple and uses leverage from the shock strut itself to streach the bungee. The shock strut can be rotated to streach the bungee WITH ONE HAND.
If you are ready to install the new bungees, I swear you can install 4 bungees in less than 4 minutes!
If you are replacing your bungees please take the time to disassemble the shock struts, clean and inspect them for wear or deterioration and make sure the small leather disk is still inside to cushion the movement! Lube and reassemble.
I hope this will be useful to some of you. If you have any questions don't hesitate to ask!
