Did exactly what was described with one caveat. The alignment bar is about 0.010\" too small on the end diameter. It's turned to 0.997\"and it should be 1.010\". This is a critical dimension to gauge the true alignment of the coupler to the Gimbal bearing. I was still able to confirm the alignment was good enough as it's still fairly close, but bear this in mind. As far as everyone else. This is probably the best designed puller of all the others I have seen and it worked flawlessly. Same goes for reinstalling. I had to return another set from another seller due to the installation tool ID being far too large for the bar and would swivel on the pin. The one from this kit was much better, not perfect but I can attest to it being well within what's needed to get your bearing back in. I have a mill so drilling the hole for the pin was a breeze, I wouldn't want to do it without one, but some people are creative.
