CamPac Kadee mounts for the F3 Overview This is a page under construction, which will show some highlights of using the CamPac 3d printed body mounts for centerset Kadees on USA Trains F3's. It is not intended to be an in-depth how to, and links will be provided to the official CamaPac site and instructions. The picture below shows the alignment on Ted's layout, an E8 on the left and F3 on the right The picture below shows alignment on my Santa Fe B unit with the same mount. I had to use the Kadee .032" shim to get the alignment on these mounts The picture below shows the variation in the pivot hole in the early AAR couplers I purchased and the more recent "faceted hole" AAR couplers from Kadee. Note well: the original pre-AAR Kadee couplers have a smaller center hole and cannot be used unless you ream them out. The picture below shows the stock "centering" whisker that should be removed. You can open the body shell and and unfasten it, or you can cut it off from the outside with a par of flush cutters. Below is a picture of the F3 pilot as modified to clear the coupler. Dimensions are given in the CamPac installation guide. The slot is cut down flush with the top of rectangular "bumper", required for clearance of the "glad hand" to swing to the extremes.
