Brulé then used a degree wheel on the crank and a dial indicator on top of the number one piston, and attached a movable wire firmly to the block. He turned the crank until the dial indicator read 0.20 one way and jotted down the crank degree. Then, he rotated the crank in the opposite direction until the dial indicator read 0.020 and jotted down that number/degree. Brulé took the two numbers/degrees, added them up, and divided the total by two; the final number is the true TDC in degrees. Brulé then set the degree wheel to the final number, and, using the wire attached to the block, moved it to the TDC on the degree crank wheel.
