  9. Divide the crankshaft damper into three equally sized segments as follows:
    1. Using a tape measure, measure the circumference of the crankshaft damper and divide the measurement by three (3).
    2. Measure that distance in a counterclockwise direction from the first balancer mark and place another mark on the balancer.
    3. From the second damper mark, again measure in a counterclockwise direction and place a mark on the damper at the same distance you measured when placing the second damper mark. The damper should now be marked in three equally spaced locations and the damper TDC mark should be in the 12 o'clock position.
