After every 40 hours of actual operation:
Thoroughly clean and lubricate Main Gear, Drive Gear, male and female Tool
Slides, Feed Screws, and Tripper Block Assy.
Non-scheduled maintenance:
Readjust the Main Bearing pre-load if the Clamshell generates excessive
heat or if the Main Bearing becomes loose. Refer to ‘Adjustment of the Main
Bearing pre-load’ later in this section.
Thoroughly clean and check the Tool Blocks in the event of feed problems.
STORAGE
If the Clamshell is to be stored or if it will remain out of service for a significant
period of time (30 days or more), it should be thoroughly cleaned lubricated and
sprayed with a rust preventative prior to storage.
ADJUSTMENT OF THE MAIN BEARING PRE-LOAD
Loosen all Bearing Adjustment Lock Screws about 1/2 turn (1 through 24).
Turn in Bearing Adjustment Screws (1, 5, 9, 13, 17, and 21) so that they are
snugged tightly.
This ensures that the Bearings are fully pushed forward. Refer to the Bearing
Adjustment Screw locations.
Lightly turn in the remaining Bearing Adjustment Screws in the order shown until all
of the Bearings make contact with the Headstock.
Relax Bearing Adjustment Screws (1, 5, 9, 13, 17, and 21) and resnug them so that
all of the Bearing Adjustment Screws are evenly loaded against the Bearings.
Connect the hydraulic power supply and apply power to the Clamshell so that it is
running at full speed.
Adjust the Bearing Adjustment Screws (1 through 24) so that the Clamshell rotation
slows slightly.
Listen for a change in the sound of the Hydraulic Motors.
Adjust the Bearing Adjustment Screws in small increments so that the Bearings are
loaded evenly.
