End Gears - Grizzly G0824 Owner's Manual

End Gears

The following subsections explain how to config-
ure the end gears. The end gears must be config-
ured according to the feeds/speeds and threading
charts in order to perform specific power feed or
threading operations.
In order to set these up properly according to the
configurations show on the charts, you first need
a basic understanding of the gears and positions
referenced on the charts. Use Figure 73 to identify
the upper "a" position gear, middle 120T/127T end
gears, and lower "b" position gear, also referenced
on the headstock feed and threading charts.

Power Feed Configuration
Install either a 60T or 30T gear in the upper "a"
position and mesh it with the 127T gear. Gear
selection depends upon which feed speed is
selected. Install another 60T gear in the bottom
position, and mesh it with the 127T gear. Install
the 120/127T combo gear in the middle position
with the 127T gear facing the headstock.

Inch Threading Configuration
Install an end gear corresponding to the "b" row
on the chart in the lower "b" position so it meshes
with the 127T gear. Install an end gear corre-
sponding to the "a" row in the upper "a" position
and mesh it with the 127T gear, as shown below.
Install the 120/127T combo gear in the middle
position with the 127T gear facing the headstock.

Metric Threading Configuration
An end gear corresponding to the "b" row on the
chart is installed in the lower "b" position so it
meshes with the inner 120T gear. An end gear
corresponding to the "a" row is installed in the "a"
position so it meshes with the outer 127T gear, as
shown below. Install the 120/127T combo gear in
the middle position with the 127T gear facing the
headstock.
