5. Relax Bearing Adjustment Set Screws (all circled) and resnug them so that all
of the Bearing Adjustment Set Screws are evenly loaded against the Bearing.
6. Connect the air supply and apply power to the Clamshell so that it is running
at full speed.
7. Adjust the Bearing Adjustment Set Screws (all numbers) so that the
Clamshell rotation slows slightly. (Refer to Fig. 3 and Fig. 4 for recommended
sequence).
8. Listen for a change in the sound of the Air Motor.
9. Adjust the Set Screws in small increments so that the bearing is loaded
evenly.
10. Check that the Set Screws are snugged to ensure that the bearing is
uniformly loaded.
11. The drive torque as measured at the drive socket should be 5 to 10 ft-lbs. (7
to 14 N-m).
12. 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.
13. Lock the Bearing pre-load by tightening the Bearing Adjustment Lock Screws.
Refer to the numbers in Fig. 3 and Figr. 4.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.
