WARNING:
All of the Set Screws should be snugged to ensure that the bearing is uniformly
loaded.
Drive torque as measured at the drive socket should be 5 to 10 ft-lbs. (7 to 14 N-m).
The safe torque range on the Bearing Adjustment Set Screws is 1 to 3 in-lbs.
(.1 to .3 N-m).
Over-tightening the Bearing Adjustment Set Screws will result in accelerated bearing
wear and lower available power.
Lock the Bearing pre-load by tightening the Bearing Adjustment Lock Screws
(Identified by letters)
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 insure that no chips, dirt or dust have damaged the gear.
Remove both of the front Thrust Plates by removing the Hold down Screws.
Lift the Headstock from the Housing.
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.
Check the Housing cavity for chips, dirt and/or corrosion.
