HELP TIMED Explain what Sam can do to fix his engine in the following scenario.

Situation: Sam tried out a new hobby and rebuilt a car from scratch. When he got to the crankshaft, he was careful to attach it to the camshaft with the gears. He also made sure that the pistons were tightly attached to the crankshaft gears as well. It was also held in place by a series of journals. Finally, he made sure that the belt was in place on one side of the crankshaft. When James came over to look at the car, he noticed that Sam's crankshaft was still incomplete.
