Mercedes always used timing chains on all their vehicles. There is also no replacement maintenance date, since they are good for the life of the vehicle. It is a rare instance that a Mercedes timing chain may need replacement. It is more likely that the tensioner has worn or failed than the timing chain. Linear Automotive proudly uses recommended factory OEM parts and fluids for repairs and services. The function of the timing chain is the same as the timing belt. It synchronizes both the camshaft with the crankshaft rotations. This timing also controls the valves sequence of opening and closing during combustion.
Timing chains are made of a chain that looks similar to a double bicycle chain that has double links side by side allowing for a double toothed sprocket to grab onto. These are very strong and virtually never break. However, the chain can stretch and get loose and may make noises by bouncing on the sprockets. If the sprocket gears get worn or the adjuster is worn, the timing chain can be adjusted.
Symptoms of a timing chain that needs replacement are a sluggish pickup, a clicking, clattering or rattling noises in the engine compartment, and a change in the engine’s performance that occurred abruptly. It is also common that when the engine is cold that there is first a loud timing chain clattering till the engine warms up and the sound may go away completely or will then quiet down almost entirely.
One test that can typically be done is to check the amount of movement in the timing chain. First remove the distributor cap to get to the timing chain. Then try to move the crankshaft clockwise and note the amount of movement and measure it. Then repeat the test by moving the crankshaft counter clockwise and again note the amount of movement and measure it. Then add up the total movement. If it is more than 10 to 15 degrees then it would indicate that the chain is too loose. It is either loose due to stretching or possibly the tensioner is broken or a gear is worn.
To check whether the tensioner is a problem affecting your timing chain without taking everything apart, you can put your ears to a test. If it rattles when you accelerate, there may be too much force on the tensioner pulley or possibly it’s cracked. When accelerating from a low speed, check whether the speed changes smoothly and gradually or erratically indicating a tensioner problem. If there is a humming noise that is intermittent, the bearings of the tensioner may be worn out. Also when accelerating if there is too much pressure on the tensioner there may be extra clattering when changing gears. This indicates that the tensioner needs replacing. Lastly, check for any leaks around the crankshaft or camshaft where the sealed tensioner bearings may be cracked and leaking grease. If this is true, then the tensioner might fail quickly. The certified mechanics at Linear Automotive can determine the problem with your timing chain, tensioner, bearings and gears and discuss the best plan for your vehicle.
