Had the same problem with the round gear legs into brackets on the wing spar in my Falconar F-12. Welded 3/8" thick bushing on the outside of the bolt hole on the bracket to solved the problem of wear.Installed new tires and tubes yesterday. Found an item that needs to be checked during every preflight. The gear leg, I will call them pin bolts on the gear, of the Tailwind need to be checked. After raising up the gear legs individually to replace the tires I found that there was some wobble in the gear legs. Tightened up the bolts and no issues. May have been there for 20 years as I'm not the builder but I'm going to order some close tolerance bolts and if necessary ream out the holes to fit. Again I don't think this is a big issue because they snugged up easily but something to be aware of for any body that has Tailwinds.
Thanks for the information Pops. That may be what I do as well for reinforcement.Had the same problem with the round gear legs into brackets on the wing spar in my Falconar F-12. Welded 3/8" thick bushing on the outside of the bolt hole on the bracket to solved the problem of wear.
This might be a stupid question but is that teal wheel assembly off of W10? Looks pretty heavy duty.Took the tailwheel assembly off the plane, I've been getting some bad shimmy. I rebent the springs by clamping them in a bench vise using a big monkey wrench with all my weight hanging from it and bouncing. Scary. Got about 4° more angle. Then I disassembled, cleaned, and greased the swivel assembly, and machined a 5° angled spacer to replace the original 1½ to 1¾ spacer (the one in the back in the pictures). That may be too much, I'll see after I get it back on the plane tomorrow, I can always machine the spacer back to less angle.

W10??? It's on my Hatz.This might be a stupid question but is that teal wheel assembly off of W10? Looks pretty heavy duty.
Yup, just not as pretty... it's an old one, 1980s vintage, when Craftsman still meant quality.Does that Craftsman box work as well as a Snap-on?
Someone has to do it.Flew last night. The re-bent spring plus the angled shim was clearly too much once I got it mounted, I figured I'd at least taxi it too see how it behaved... definitely too much. Put the straight shim back in, much better, not a trace of shimmy.
Right now there's about 9° of negative caster, as near as I can measure it, with half fuel and nobody in the seats. It might still be a wee bit too much but I'll wait a bit to see if the spring relaxes during the next few flights, if not I can machine the shim back to a lesser angle and install it the opposite way. Alaskan Bushwheels recommends 5-7° but I think it was about 5° before when it was shimmying badly. Of course cleaning and regreasing the swivel assembly no doubt helped also. I guess I'll just have to go flying again to see... oh, the burden!
