        The two "Y" shaped mounts on top of the big "U" screw in and out of the wing. They should NOT push the struts down or up. They are just their to stabilize it in compression. DO NOT adjust them until they try to bend the struts!!!

        I know most of us know that, but lots of new people do not and it is scary to see a plane where someone tried to adjust the washout with the jurry strut.

          The part that screws into the bottom of the wing sort of looks like an upside down "U" is the part that you screw in or out to make adjustments.

          To make the adjustment you need to have the lift struts on. Then look down the trailing edge of a lift strut.

          When I say look I really mean "sight" down the trailing edge like you would sight down a shotgun or rifle barrel.

          The goal is to make the trailing edge straight.

          For example if the rear strut trailing edge (TE) bows down then screw the rear adjuster up so as to straighten the trailing edge. Or the other way around if the TE bows up. Do the same for both struts.

          There is supposed to be a thin nut on the adjuster to use as a jam nut so you can lock the adjuster in place when you are done.

            This is the thing you screw in or out of the wing at the top of the jury strut assembly (what he described as a "U" and I called a "Y"). Dave is making the same point I was. DON'T bend the strut with the adjustment (it is easy to do). It is NOT a wing adjustment, it is a strut stabilizer to keep the strut from failing in compression by buckling. It basically makes the strut act like it is two struts half as long, which is stronger in buckling.

            Second photo is the actual jury strut. All this talk about "Ys" and "Us" can get confusing. ;-)

              OK, Jury strut photo went through but the jury strut fitting didn't. Let's try again.

                  Hi All, looking for wheel alignment info! I searched & found Toed-in (0 to 1/8" @ 18") Is the airplane on three points ? and what is the Camber? Plane with Empty weight should positive camber of a few degrees?
                  any input would be helpful.
                  Thanks Steve

                    That spec came from what I got my airplane to. I didn't check camber, because it changes as the gear moves up and down. Have new gear bumpers, use the axe handle savers, order from Amazon. I did them with the tail in the air. I put the tailwheel up on a stool and align it with a 5" piece of pipe by sliding the pipe over the axle with the gear on short jack stands and reef on it. You want to drop a plumb from the center bolt of the tail wheel spring and the center of the spinner. Then you need to get each side centered on that line, or the aircraft will dog track. I made a tool to do this, but you can buy 2 pieces of 1" aluminum square tubing, bore a 3/4" hole through it in the middle, slide it over and level each side and measure. Hope this helps, if you have any questions, pm me. Tim
