Changing Gears - Grizzly G4015Z Owner's Manual

Changing Gears

Changing gears on the Model G4015Z is straight
forward. Refer to the label found inside of the
Lower Belt Guard for proper gear selection while
following the example below. We will be changing
the gears to those that would be used to set the
machine for a 0.002" per revolution feed rate.
These instructions assume that all of the gears
need to be changed. The number of teeth are
stamped on each gear. To begin:
1. Unplug the machine.
Remove the nuts on the end of the shafts for
2.
gears A and D.
3. Loosen the cap screw at the bottom of the
gear support arm and allow the arm to rotate
downward as in Figure 39.
Remove the cap screw in the middle of the
4.
combination gear B/C. This will allow
removal of the gears and bushing supporting
them. A tee-nut will remain in the gear sup-
port arm as in Figure 40.
Remove gears A and D.

Make sure the gears mesh properly before oper-
ating the machine. The gears are properly
meshed when the teeth between 2 gears are
fully engaged. Damage to the gears will occur if
adjustments are not correct.
