Before you take anything apart on the mill, use it to make some spacer plates and get some longer bolts to mount the new motors.

They have the same face dimensions, but the shafts are 5mm longer than the old brush servos. There was no clearance between the motor shaft and ball screw inside the coupler, so I need shorten the 32mm long 19mm diam shafts by 5mm. Can this be done without damage to the motor from heat or vibration? I don't want to have to pull the ball screws.
