Main bearing studs are first screwed into the block just short of bottoming out. Then, with nuts installed, they're torqued to 60-70 ft-lb. McLearran begins at the No. 3 main cap and torques in third values, beginning at 23 lb-ft. There are seven main caps you must torque in this order-3-5-2-6-4-1-7. Check how smoothly the crank rotates each time. Next, torque to 46 ft-lb in the same order and check rotation. Lastly, torque to 70 ft-lb in the same order and check crank rotation. You should be able to turn the crank with your fingertips and a 1/2-inch drive ratchet. If machine work is spot on, resistance to crank rotation should remain the same with each torque sequence.
