Inch Threading Configuration
Install a spacer in the Z1 position, and install end
gears in the Z2, Z3, Z4, and L positions. Mesh
the Z2 gear with the Z3 gear, and mesh the Z4
gear with the L gear. Just like the Z1/Z2 and Z3/
Z4 gears, the L gear can be installed in either the
inner or outer position on the shaft. The "H" desig-
nation in the L row shown in the chart below indi-
cates a spacer is to be installed in that position.
Loosen the mounting hardware necessary and
adjust backlash to between 0.002"–0.004".
Tighten the hardware once the adjustment is
complete and the gears are meshed correctly. Set
the feed rate selector to A, B, or C.
