WARNING:
Lock the Bearing pre-load by tightening the Bearing Adjustment Lock Screws.
(1 through 24).
The safe torque should be 8 to 10 ft-lbs. (11 to 14 N-m).
Too much torque may crack the Bearing while too little torque may allow the
Bearing pre-load to relax.
INSPECTION OF THE MAIN GEAR
If the Headstock does not run smoothly, even after adjustment, inspect the Main
Gear to ensure that no chips, dirt or dust has damaged the gear.
Remove both of the front Thrust Plates by removing the twenty-two (22) Hold Down
Screws.
Lift the Headstock from the Housing. Refer to the 'Clamshell Nomenclature'.
The Main Gear and the Main Bearing may now be inspected.
Check the Bearing, Housing, and the race on the Gear.
All surfaces should be smooth, without scratches, and they should feature even
wear patterns over the entire surface.
