Feed Clutch Adjustment - Grizzly G0750GV Owner's Manual

Feed Clutch
Adjustment
This lathe is equipped with a feed rod clutch (see
Figure 128) that connects the feed drive hub with
the feed rod through a set of spring-loaded ball
bearings. This clutch helps protect the apron feed
system from overload. The feed rod clutch comes
set from the factory, and unless there is a prob-
lem, it needs no adjustment.

The clutch may slip if the path for the carriage
or the cross feed is obstructed during turning
or facing operations, the tool bit crashes into a
workpiece shoulder, the carriage lock is incor-
rectly tightened when the feed selection lever is
engaged, or if too deep of a cut is taken—causing
a sudden binding of the tool and workpiece.
Never completely tighten the feed clutch past its
normal setting in an attempt to completely elimi-
nate clutch slip. Doing so will void the warranty,
and can lead to a non-slipping clutch, resulting in
catastrophic gearbox damage.

— If clutch slips during normal work loads,
increase clutch spring pressure by tight-
ening each clutch drive set screw (see
Figure 128) one full turn, then recheck for
slippage.
— If clutch does not slip when it should,
reduce clutch spring pressure by loosen-
ing each clutch set screw one full turn,
then recheck for slippage.
