11. Compression Load Cell (Compression Load Cell Style Backups Only)
Apply grease to the flat surfaces of the compression load cell where contact is made with the rear leg and the paddle of the
backup.
Farr recommends that a liberal coating of grease be applied to the cam surface of the rotary drive gear prior to jaw installation.
Also, the clutch inspection plate should periodically be removed and a coating of grease applied to the clutch, drive gears and
shifting shaft.
D. ADJUSTMENTS

Brake Band Tension Adjustment:

The top and bottom brake bands must be periodically adjusted to continue to provide smooth and efficient jaw cam action. If
the cage plate turns with the rotary gear, the jaws will not cam properly and, therefore, will not bite on the tubing or casing.
Tightening the brake band against the cage plates will increase frictional resistance, allowing jaws to cam properly and grip the
casing. Adjust the brake band using the adjustment nut and bolt set as shown in the illustration below. Use caution, as over-
tightening will cause excessive wear to the brake bands.
