Sherline Mill X and Y-Axis Backlash Upgrade 5011U
In 1997 the old pointer style lock was replaced with a star gear type lock to make adjustment easier. With the advent of CNC (Computer control) there has been an increased demand for reduced backlash settings. To serve this purpose, the size of the teeth on the star gear have been reduced.
All new Sherline machines after 6/04 include these revised star gear backlash nuts and lock. It will not replace the pointer system as the hole centers for the lock are different.
Be careful when removing the motor shaft from the coupling. From inside the mount, remove the two socket head cap screws that hold the mount to the mill base.
Without reinstalling the motor, you can rotate the leadscrew to remove it from the insert in the saddle by using a 3/32″ hex key. Now you can pull out the mount/ coupling/leadscrew assembly. Remove the old backlash nut, install the new one and reverse the procedure to reattach the mount to the base.
