Place a .0005" indicator against the motor mount
and hand jog the C-axis to check the runout.
Loosen the 4 bolts and adjust the cylinder block
until the runout is between .0003-.0005".
Torque the 4 cylinder block bolts and check (by
jogging) to see that the axis runs smoothly and is
still in the .0003-.0005" range for runout.
Make sure to pull back the indicator before
disengaging the C-axis. You can use M155 or E-
stop for disengaging it.
