If you can't get the gear leg high enough to match the U-01404 and U-01405 pieces (blue, below) because the gear leg binds in the U-1402 piece (red, below), you may need to remove material from the leg (in addition to the powder coat). This was an issue I ran into when I attached my gear legs
. My experience is described in that link in much greater detail.
A consultation with Van's elucidated that during the Main Gear Leg's manufacture, the heating and bending processes can cause the edges of the leg to bow outwards, effectively increasing the thickness of the leg (in the fore-aft/longitudinal axis). They advised me that is was acceptable to file down the edges of the gear leg to achieve proper fitment.
I removed material from the fore and aft faces...
And powder coat from the outboard faces...
If desired, you can spot prime the exposed areas with a light coat of your preferred primer (I suggest not using a water-based primer on steel, lest you get flash rust, something I learned about when priming the aileron pushrods
A couple of other things to watch out for..
You may need a shim at U-01405 (mind the bolt length if you do)...
Also, keep in mind, per Van's, that the U-01403 Gear Attachment Bar should not be flush against U-01402 Lower Gear Brace since if it were, the gear leg may not be properly captured by the Gear Attachment Bar. You should see a gap there (e.g.
, mine was 0.03" on the left side). In other words, if you don't see a gap here, you may have removed too much material from the outboard/inboard face(s) of the gear leg.
