When I initially setup the turbo for install, I followed the Hahn instructions and loosened the 12 bolts (6 per side) that lock the turbo's cold (compression) and hot (drive) sides to the center bearing section housing the oil feed and drain lines. At the time, IIRC, the center section turned independently of the outer sections. I then tightened the bolts for the hot side and installed the drain line, using the rubber hose in the length supplied by Hahn. I then installed the oil feed line and thought I was ready to tighten the cold side bolts, but noticed the drain and oil feed lines were no longer vertical and had shifted. After loosening and trying 2x to reclock the turbo to better position the oil lines closer to vertical, I've realized the center section no longer seems to rotate independently of the two outer housings.
Using an app on my phone, I measured the angle of the feed line and oil drain lines. The attached animated GIF shows how the turbo output clocked against the frame rail with the turbo output NOT in line with the Intercooler input, and the oil feed and drain lines were measured as 15 degrees off vertical, which, from what I've read, is the max allowed deviation off vertical. The GIF also shows that if I move the turbo output clockwise to position the output in line with the Intercooler input, the center section also rotates, placing the oil feed and drain lines even farther out of vertical, outside the recommended limits.
