I installed a new engine and have spent half a day trying to align it. I also replaced the gimbal bearing, the drive is an Alpha. I used machinest die on the end of the alignment tool and while the alignment improved with adjustments, I consistently had strike marks on the port side of the tool. I tapped the tool to align the gimbal as prescribed in other posts, the result was the same. I finally noticed that the gimbal bearing slides around a bit and after getting it to slightly slide laterally , the alignment is close. Currently the tool slides in easily, however as it enters the coupler there is a slight bump and the tool pitches upward (very slight). I can hold it with 2 fingers and slide it in. But, I'm hoping someone can confirm whether moving the gimbal so it aligns with the coupler is the right or wrong approach.
