What causes a cam sprocket to rotate on a timing chain?

The chain tensioner (2) attempts to take up the excess slack in the timing chain. When the tensioner piston extends, the chain is pulled tight. Removing this slack on one side of the chain also causes the cam sprocket (3) to rotate and change camshaft timing on that bank.

What happens when you remove the slack on the timing chain?

Removing this slack on one side of the chain also causes the cam sprocket (3) to rotate and change camshaft timing on that bank. Rotating one cam sprocket disturbs valve timing relative to the other side of the engine.

What are the different types of timing chain?

There are two common chain designs used in today’s engines: the link chain and the roller chain. Non-roller chains, or link chains, have stacked rows of flat links connected together via pins. The links are shaped to fit the contour of the teeth on the timing gear or sprocket. Roller versus Non-Roller chains. The chain on the left is a non-roller.
