6.Move the middle gears up to mesh with the top gear, then tighten the hex nut to hold it in place.

Note: When meshing the middle gears, make sure there is a backlash of 0.001"–0.002" between the gears.

7.Move the pivot assembly to the right to mesh the middle gears with the bottom gear, then tighten the pivot hex nut.

8.Disengage the feed gearing and make sure the gears rotate with the correct amount of backlash, then close and secure the left side door.

NOTICE

Carriage feed rate is dependent upon the spindle speed—higher spindle speeds equal higher feed rates! Pay close atten- tion to the movement of the carriage or cross slide and keep your hand poised over the power feed lever to disengage it when necessary. Failure to fully understand this could result in the lathe components crash- ing into each other causing severe damage to the lathe.

Engaging Power Feed

Carriage or cross slide powered movement for non-threading operations uses the feed rod. For threading, the longitudinal leadscrew and half- nut are used (refer to Threading on Page 46 for detailed instructions).

To engage the power feed for non-threading operations:

1.Make sure the spindle is OFF and has come to a complete stop.

Model G0554Z (Mfg 01/09+)

2.Use the power feed direction lever to select the rotation direction of the feed rod (see the illustration in Figure 61).

Note: The direction arrows shown above and below the power feed direction lever are only accurate when the spindle is rotating coun- terclockwise (toward the operator). As the spindle reverses, so will the direction of the power feed.

3.Use the power feed lever on the front of the apron to select powered movement of the carriage or the cross slide (see Figure 62).

—For longitudinal power feed of the carriage, pull the lever to the right and up.

—For power feed of the cross slide, push the lever to the left and down.
