Feed Clutch Adjustment - Grizzly G0949G Owner's Manual

Feed Clutch
Adjustment
This lathe is equipped with a feed rod clutch,
shown in Figure 114, 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 problem, 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 eliminate 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 of four clutch drive set screws
shown in Figure 114 one full turn, then
recheck for slippage.
— If clutch does not slip when it should,
reduce clutch spring pressure by loosen-
ing each of four clutch set screws one full
turn, then recheck for slippage.
