Page 26: Gear-Bearing Bolt Maintenance
Gear-Bearing Bolt Maintenance Once a bolt has been torqued to 75% of its proof load and then removed, the torque coefficient may no longer be the same as when the bolt was new thus giving indeterminate damp loads after torquing. Anytime a gear-bearing bolt is removed, it must be replaced with a new bolt of WARNING the identical grade and size. -
