INSPECTION OF THE MAIN GEAR
When 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 the front Thrust Plates by removing the forty-eight (48) Hold Down Screws.
Lift the Headstock from the Housing.
The Main Gear and the Main bearings may now be inspected.
Check the Bearings, 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 Inc.
Place the Headstock carefully back into the Housing.
Bolt the Front Thrust Plates back into place.
When the bearing pre-load was properly adjusted before disassembly, then it will still
be adjusted when reassembled.
Drive Gear and Main Gear Lubrication
Remove the Drive Housings.
Inspect both the Drive and Main Gears for chips or burrs, clean as required.
Coat the teeth of the Drive Gear and the Main Gear with a grease that is
approved by TRI TOOL Inc.
