TIGHTENINGTORQUE :
Precautions
•
The Fasteners should be tightened to following specified torque.
•
If the fasteners are not tightened to specified torque that is either over tightened or under tightened. It will result
in leakage at joints & damage to the parts/threads. It will also adversely affect the performances of the parts /
system because various clearances / bearing plays in the aggregates are governed by the recommended
torques of the fasteners.
•
When choosing the torque wrench, remember that it should not be subjected to torque exceeding three fourth
of its capacity.
•
Before tightening, clean the threads & apply a little oil if required.
