Which tool is commonly used to check the alignment of a crankshaft?

• Torque wrench

• Dial indicator

• Feeler gauge

• Micrometer

During piston installation, what is the recommended orientation for the piston ring gaps?

• All gaps aligned in a straight line

• Staggered around the piston

• Aligned with the piston pin

• Aligned with the cylinder head

What is the function of a timing belt in an engine?

• To connect the pistons to the crankshaft

• To synchronize the rotation of the crankshaft and camshaft

• To increase fuel efficiency

• To reduce engine noise

When replacing a timing belt, what is a critical step to ensure proper engine function?

• Lubricating the belt with oil

• Aligning the timing marks on the camshaft and crankshaft

• Tightening the belt as much as possible

• Painting the belt for identification

What is the typical consequence of a misaligned crankshaft?
