Mack cyclinder head
For the 1977 Mack ENDT 676 engine, the cylinder head torque sequence typically involves tightening the head bolts in two or three stages. Generally, you start at the center bolts and work your way outwards in a crisscross pattern to ensure even pressure. The initial torque usually involves setting the bolts to around 90 ft-lbs, followed by a final torque of approximately 130 ft-lbs, depending on the specific service manual instructions. Always refer to the manufacturer's service manual for the most accurate and detailed specifications.
