ENGINE 273 MPFI 53 ENGINE 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.
