I once changed the bolts that hold the main undercarriage to the spar (in my case, the fixed main landing gear holds with two large L-shaped brackets to the main spar). I had the idea to put two protruding eye nuts, in order to use them as tie down points. I seldom used them as tie-down points, but they prove very useful as jack-up points. The eyes being round, they compensate the pitch attitude nicely, so I can jack no matter whether the tail is up or down.

I used two C clamps to clamp a scrap block of aluminum to the leg (piece of wood 2X4 should also work fine) and I just put a cheap bottle jack under it. On my KR I had the 1/4" threaded hole in the center of the axle for holding on the wheel pants. I used to use a 4' piece of 2X4 with a screw in the side of it about 10" from the end. I would put a 2" bolt in the threaded hole in the axle and use the 2X4 as a lever to lift the plane. The screw in the board was put under the bolt and that kept the plane from sliding down the board as it was lifted. I had a couple of other wood blocks that were the right height to put under the gear leg when it was lifted.

Thanks! +++++++++++++++++++++++++++++++++++++++++++++++++++++++ I've not done it personally but I know an A&P, IA, that uses a LARGE "C" clamp. He puts some plywood on the gear leg so the "C" clamp won't damage the leg and then uses a roll-around floor jack to lift the aircraft. I know he uses this method on most flat spring gear Cessnas and your KR will be much lighter. I'd suggest that after you have the aircraft raised you block it to stabilize it and keep it from falling on you. A friend of mine was killed trying to change landing gear bungees when the airplane fell on him. Damn shame..........
