WARNING:
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 (A
through F).
The safe torque should be 6 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 has damaged the gear.
Remove both of the front Thrust Plates by removing the eight (8) Hold Down
Screws.
Lift the Headstock from the Housing. Refer to the Clamshell cross section.
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.
To reassemble, wipe clean all of the Bearing surfaces and clean the Housing cavity.
Re-grease the Gear using a lubricant approved by Tri Tool. Refer to the Lubricant
Recommendations located later in this section.
Place the Headstock carefully back into the Housing.
Bolt the Front Thrust Plates back into place.
If the bearing pre-load was properly adjusted before disassembly, then it will still be
adjusted when reassembled.
