Re: Replacing Landing Gear Bushing

I have not seen one of Dave's tools in person, but if it comes up and hits the bottom of the bungee stubs solidly I wouldn't have an issue with rolling the bungees off, and putting them back on later. The tool would need to be real solid to keep from rocking when the bungee comes off.

Re: Replacing Landing Gear Bushing

Though I have not personally used it, Tom, another individual has. Apparently it is very stable. However, the more I think about it maybe the bushing can wait until I have to change out bungees. Too many variables involved that could result in injury to me or the plane.

Dave, I know you tried but you noticed where I have to contact him at, now. Not here, but Facebook. Lol

Thanks all for your comments and suggestions.

Bumper jack and a web strap, lift the bungie off and then lower the jack....Tim

You could change just the bolts for now.

I change them by driving out the old bolt with a greased bolt used or new that I use as a tool, just make sure that the bolts always stay in contact with each other until the old one is all the way out. That way the hinge is always complete and loading makes little effect.

Then grease up a new replacement bolt and drive out the "tool" bolt.

Hi Tom,

It locks on to the bottom as you mentioned. It is very solid.

The thing that prevents me from recommending using it for bungee removal is that I do not have a good way to get the bungees back onto the tool "ears" from the airplanes "ears".

My mantra has been that no personal strength can be involved. They have to raise up about 3/4" or more and I have not devised a good method for that.

If you guys can think of one then try it.

Re: Replacing Landing Gear Bushing

I helped another TCraft owner remove bungees intact from his '41.
It was a lot of years ago. But I remember that he used a 2x4 about 4-5 feet long as a lever.
He made a fulcrum by stacking a couple of short 4x4 blocks on his floorboards. He was careful to position the fulcrum so that the load transferred into the structure.
Then he passed a couple of loops of parachute cord through the bungee loop and attached the cord to one end of the 2x4 (I don't remember how it attached).
The other end of the 2x4 was sticking out of the door in front of the lift struts.
The airplane was off the gear. It was a two-man job. He pulled down on the 2x4 and the top of the bungee loop went up. Then we worked it off.
We discussed that if things went badly, the 2x4 might end up poking through the bottom fabric of the wing. But it wasn't scary at all. It worked as planned.
