End Gear Setup

The gearbox drive gear on this lathe can be configured for the "normal position" or the "alternate position" (both described in following paragraphs), depending upon the type of operation to be performed. The lathe is shipped with the end gears in the normal position. Gears must be thoroughly cleaned and re-coated in grease before installing (refer to Page 61), and the backlash must be maintained at 0.005" for correct meshing.

Normal Position

The 24T end gear is installed in the top position, the 44T/56T end gears in the middle position, and the 57T end gear in the bottom position, as shown in Figure 86. In the normal position, the 56T and 57T gears are meshed, which allows for inch and metric threading and all general feed operations.

Alternate Position

When the 44- and 57-tooth end gears are meshed (see Figure 87), you can perform modular and diametral pitch turning.
