I recently replaced my u/c rubbers during my Annual. I had an original "lever" type u/c tool which I used during the restoration. It worked ok but it was difficult hauling on the tool and getting the u/c bolts in. So, I have devised this tool that worked very well, with no heaving, sweating or poking holes in fabric when you slip pulling on the rubbers.
1-Suspend a/c from hangar roof or hoist by cross tube behind seat at outermost extremity. IMPORANT: the a/c will tip onto a wingtip when u/c is clear of the floor, make sure you put tressels under the wings with foam on to protect the wing.
2-Install tool and spread rubbers so there is no load on the u/c rubber A frame and remove fwd top bolt and bottom bolt on one side only.
3-Retract tool to remove load on rubbers so the old rubbers can be slipped off and new ones on.
4-Spread tool sufficiently to enable reinstallation of bolts.
5-Retract tool and remove from a/c.
Simple!
