I had the same problem with my 235, my solution, shim the axle casting to correct caster and camber misallignment.. First off, go through the adjustment of the right gear actuator found on page 292 so that the "aluminum spacer" just is tight against the face of the actuator when the gear is completely retracted, then, adjust the over-center link to get the GM-1 vertical again Now, remove the wheel and Brake Alignment Disc and shim to get rid of "the 4 deg error". A/S has stainless tapered shim stock, some farm supply Co carry them too, of varying thickness which you can trial and error to correct the wheels castor and camber for proper alignment, then drill the shim to mount between the brake alignment disk and the GM-2.
I would not mess with drilling the GM-2 or the GM-1 they will just get you in trouble later. it appears that the lower bolt boss on the GM-1 is the problem, its not perpendicular to the leg.. .. Don Skeele 850-626-4946

Subject: L235 main gear casting
To original L235 kit builders, as eventual and current builder of kit #11 I noted yesterday that the right main gear casting/wheel was not parallel to the main mounting/retracting assembly, but the left one was. That is, the right main wheel, when down and locked, was cambered inward at the ground, at a 4 degree angle, while the mounting vertical tube was vertical -- perpendicular to the ground. After checking that the axle was mounted correctly to the casting, I looked closely at the left and right castings. (see attached).
The top outer hole appears to have been drilled too close to the top of the right casting's top outer lug which mounts it to the mounting/retracting assembly.
I'm asking L235 builders whether these casting came from the factory already drilled?
If so, would Lancair have spares? I'll call.
Also, (if Lancair doesn't have spares) does someone have an unused/used casting available that is correctly drilled?
Finally, if anyone else has found a similar problem and fixed it himself, how?
Any comments, if I have to self-help this, on how to do it?:
1. if I machine the outer hole to move the center down four degrees -- about .300" --, maintaining the present outer edge of the present hole, and bushing in for a new bearing hole? I guess I should estimate the loads for landing and side loads, to see whether there's presently enough edge distance left in the present casting... to see whether I should fix this casting or not.
2. If anyone knows the casting alloy, could the hole in the casting be heated/welded before drilling a new hole int he correct location?
Any comments appreciated.
Ready to start the LyCon for the first time.
Thanks,
Terrence
