7. TIGHTENING TORQUE:
The fasteners should be tightened to specified torque at recommended intervals (km). If various fasteners
are not tightened to specify torques, that is either over tightened or left loose, it will result in leakage at joints
and damage to the parts threads. It will also adversely affect the performance of the parts/systems because
various clearances/bearing plays in the aggregates are governed by the tightening torques of the fasteners.
When choosing the torque wrench, remember that it should not be subjected to torque exceeding three
fourths of its capacity. Before tightening, clean the threads and apply a little liquid locktight.
