So the roller cracks are from over tightening the locks and the 1.25″ bolts. Neither need to be very tight. The cross bars aren’t going anywhere and I would bet that the machine would actually work fine without the roller locks. Knowing how tight you have those I suggest you go around the whole machine and loosen all of the bolts and screws. Nothing on this machine needs to be tight at all. As counter intuitive as it sounds, most of the parts work better loose.
