Grinding Head Mounting; Head Lock Handle Position Adjustment; Leadscrew Backlash Adjustment - Van Norman FG5000 Instruction Manual And Parts List

GRINDING HEAD ADJUSTMENTS (continued)
4. GRINDING HEAD MOUNTING: The grinding head motor may be mounted in any of three
positions. The machine is shipped from the factory with the motor in center position. A lower
and higher mounting position are provided with the tooling. The lower mounting holes on
the motor are then placed over these studs, two 3/8-16 cap screws are used through the
upper motor mount. When the motor is mounted in the upper position the same procedure is
used replacing the upper studs with longer ones (794-8016-19).
5. HEAD LOCK HANDLE POSITION ADJUSTMENT: The locked position of the head lock
handle is adjustable (Figure 33). To raise or lower the handle position follow the procedure
below:
a. Loosen the 3/4 hex lock nuts.
b. With upper head lock loose, turn studs with screwdriver until handle is in desired position
when the head is locked. Retighten lock nuts.

6. LEADSCREW BACKLASH ADJUSTMENT:

and nut combination may be adjusted by tightening or loosening the cap screw through the
bronze leadscrew nut. Access to the leadscrew nut is gained by removing the rear access
door. Tightening the cap screw in the bronze nut decreases the amount of backlash (Figure
34).
