Feed Clutch
Adjustment
This lathe is equipped with a feed rod clutch,
shown in 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 problem, it needs no adjustment.

Figure 128. Feed rod clutch.
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.

Point the top right dial at "N", then position
the bottom right hand gearbox dial pointer

—If the clutch slips during normal work loads,
increase the clutch spring pressure by
tightening each of the four clutch drive set
screws shown in Figure 128 one full turn,
then recheck for slippage.
—If the clutch does not slip when it should,
reduce the clutch spring pressure by loos-
ening each of the four clutch set screws
one full turn, then recheck for slippage.
