How does the timing chain work on an engine?

Every time you use the engine, the timing chain will be used. It connects the crankshaft to the camshaft. The metal links in the chain move on the tooth sprockets on the end of the crankshaft and crankshaft so that they rotate together.

What should I do to tighten my timing chain?

Tighten the chain according to your car manual’s specifications. Some chains are tensioned by adjusting either the crankshaft gear or the camshaft gear, while others have an automatic tensioner. This will vary by make and model of your car. The important thing is to make sure that your timing belt is as tight as it should be.

When to know if your timing chain is bad?

If driving an older vehicle, or one with close to 100,000 miles, it is recommended to look for symptoms of the timing chain going bad or failing. Since the timing chain can go bad and will need to be replaced, it is important to be able to recognize the symptoms and have it repaired before it fails completely.

How does a chain tensioner work on a timing chain?

A timing chain is kept under proper tension by a chain tensioner. A chain tensioner could be operated by a spring-loaded mechanism or oil pressure. Timing chain, tensioner and chain guides. See timing chain animation. Chain guides and silencers are used to keep the timing chain from vibrating. All these components wear too.

Why is my timing chain wearing out on my RX 350?

The timing chain problems are not uncommon, especially in high-mileage vehicles. Similarly to any other moving mechanical components inside any engine, a timing chain is subject to wear. A timing chain is lubricated by the engine oil. Lack of oil changes, low oil level or poor oil quality can cause the timing chain to wear faster.

When do you know to change the timing chain?

A timing chain runs inside the engine, as it needs to be lubricated by the engine oil. A timing belt typically needs to be replaced between 40,000 and 100,000 miles depending on the vehicle and it’s a few hundred dollar repair. A timing chain doesn’t need to be replaced unless there is a problem with it.

What can I do to avoid timing chain problems?

To avoid timing chain problems you should maintain your engine properly and have the engine oil changed at recommended intervals. Using premium quality engine oils and oil filters will also help. Keeping the proper oil level will ensure that the timing chain is always lubricated.

Can a timing chain be replaced on a pushrod car?

In old-style pushrod engines, replacing the timing chain is a fairly easy task. No such luck if you have a modern front-wheel drive car with a transversely-mounted engine, as the space in the engine compartment could be very tight.

A timing chain is kept under proper tension by a chain tensioner. A chain tensioner could be operated by a spring-loaded mechanism or oil pressure. Timing chain, tensioner and chain guides. See timing chain animation. Chain guides and silencers are used to keep the timing chain from vibrating. All these components wear too.

Where is the timing chain tensioner located on a Mercedes?

If the balancer is at Zero, and the distributor points to #1 then both left and right camshaft marks should align as shown in the photos above. If this is the case you are now at TDC. Remove the timing chain tensioner located on the right passengers side head held on by 13mm bolts.

How do you install a new timing chain?

This may take a couple tries. When you are sure the cam marks are lined up properly and the sprocket and the keyway on the end of the cam are lined up, you can push the sprocket back onto the cam and tighten the bolt back down. 9. Put the rocker arms back and re-install the tensioner if needed.

Do you need to check your chain tensioner timing?

DO NOT LET THE CHAIN GO SLACK AT ANY TIME. Following this simple rule should make this upgrade uneventful. If the chain does happen to slacken up, then you need to check your camshaft timing (documented in 101 Projects for Your Porsche 911).

When to replace chain tensioner on Porsche 911?

The newer style chain ramps are manufactured out of tough plastic, and are known to stand up better than the ones used on the early cars. It is recommended to replace the ramps if they show pitting, which may be caused by the chain flapping up and down. Two odd-shaped bolts that pass through the case create the mounts for the chain ramps.

What kind of chain is a timing chain made of?

A timing chain is made of metal, similar to a bicycle chain. A timing chain runs inside the engine, as it needs to be lubricated by the engine oil.

How do you remove Bank 1 timing chain?
