When do I need to replace the timing chain?
When do I need to replace the timing chain?
When the end top point “A” of timing chain is positioned at the right-hand side of chain elongation indicator, it is necessary to replace the timing chain because the timing chain elongates more than the specified length. 7.Install the upper chain guide. CAUTION
Can a timing chain jump cause a problem?
Of the many things that can go wrong with and engine, the timing chain jumping can be one of the most frustrating problems to have. Depending on the motor, it can cause all sorts of problems. They require a lot of mechanical skill to replace.
What happens when the timing chain is loose on an Audi?
Tensioners make sure the chain is tightly wound to the pulleys and gears. If the tensioner fails and the chain becomes loose, the timing of the engine is thrown off. When a timing chain is loose you’ll likely hear a rattle during startup or idling in the engine.
Why does a timing chain have a tensioner?
It ensures that the piston is close to or at top dead center at the moment of combustion. If a valve is open or the plugs don’t fire at the right time the air and fuel that have entered the combustion chamber are not going to ignite. Most timing chains use a tensioner to keep them tight and to keep them from jumping.

How to calculate the elongation of a timing chain?
5.Look at the inside of timing chain case with one eye in the direction of arrow shown in the illustration. Fix the eye line at the point where the top axis line of the chain elongation indicator at the front side of timing chain case is overlapped with that of the chain elongation indicator at the reverse side of timing chain case.
