Can a Mercedes Benz timing belt be replaced?
Timing belts will slowly degrade necessitating periodic replacement – by contrast a timing chain can theoretically go the entire life of your car without replacement. In fact, timing chain replacement isn’t even included on most Mercedes-Benz service schedules!
What causes timing failure on a Mercedes Benz?
As a result, Mercedes-Benz was able to minimise instances of a timing chain stretching. However, engines with this revised timing system can still suffer from timing failure – in the 271 CGI specifically, it’s the chain tensioners that is often a source of timing problems.
When to replace timing chain on Mercedes R107?
The timing chain and the various components (guide rails, tensioning rail, chain tensioner) wear out after 100,000 miles and should be replaced. The sprockets should also be replaced. The chains can stretch but they also wear.
What causes timing failure on a Mercedes 271 CGI?
However, engines with this revised timing system can still suffer from timing failure – in the 271 CGI specifically, it’s the chain tensioners that is often a source of timing problems. Tensioners apply pressure to your timing chain, keeping it nice and tense, therefore helping maintain fit between the timing chain and the camshaft sprocket.
When to change the timing chain on a Mercedes Benz?
Timing chain is an internal component and should not be changed unless the engine goes bad….You have to dismantle the engine to change it.
Why do timing belts need to be replaced?
Timing belts are far more susceptible to breaking but chains can stretch leading to other issues. In many examples there are unacceptable degrees of chain slack and worn or broken guides. These need to be replaced. Neglecting the chain can lead to catastrophic results.
How do you change the timing chain on a radiator?
Trace the radiator hoses from the radiator back to the engine. Squeeze the hose clamps with pliers and slide them back onto the hose. Wiggle the hose to break it free and move it out of the way. There is no need to remove the radiator.
What’s the best way to remove a timing chain?
Put the bolt partially back in the bolt hole and use a harmonic balancer removal tool. The tool should not be a jaw type tool, but instead should apply all of the removal force to the center of the assembly. This protects the rubber ring in the harmonic balancer. Remove the timing chain cover.
