[QUOTE="Trickymissfit, post: 1066061, member: 25383"] the idea of the dowel pins is to return to proper alignment after the machine is bumped out of alignment. You loosen the bolts and install the pins. Then retighten all the bolts. Once done you pull the pins again. That way you always have a good reference to go from. Might add here that if the machine fails to properly align with the pins in place; it's time to relevel and align the frame again. I've seen wrecks so hard that they ripped the hardened ways off the frame! But always got them back to OEM condition in due time. (have had wrecks that took close to a month to fix) Ball screws are a different animal. Once you replace the screw, the OEM dowel pin holes are useless. That shim plate they often come with is only a reference point after that. You'll probably never use it again. I built and rebuilt machinery for a living, it was a constant learning process. Have seen some pretty good setups, and have seen my share of seriously bad setups in my lifetime. [/QUOTE]
