Manufacturers were being increasingly blamed for these problems, which has led many to make the switch from belt to chain. These parts also wear out and may need replacement sooner than the chain. When the chain breaks there is nothing to turn the cam shaft and the valves can be left open where upon the piston comes into contact with the open valve, the degree of damage would depend on the position of the valve s when the chain breaks. Update: Removal of cam cover Valve cover removed: From there I basically used a dremel with a tungsten carbide round tip and shaved down the pins. You would have had to force it to cause problems. Replacement of old part may also require 1 272 052 13 16 Tensioner Arm and 1 272 050 08 11 Chain Tensioner. If while driving the water temperature light, or ignition light comes on in the instrument cluster, there is every chance that the poly V belt has broken, and that the alternator is no longer producing power and the water pump has stopped circulating the coolant around the cooling system.
If not what is your vin and I will look up the timing alignment procedureHi krazzdav, No I did not put the valve cover back in before rotating the engine manually. It rotated however, at about 60 or 90 degrees a turn, the crank got really hard and stopped immediately and brought it back a little. In older models it is more often than not the cause of the car being scrapped, so the car outlasted the chain! I'm shocked that plastic parts are used for something that is as important as the timing chain, even though the plastic is very hard. Problem is most of the cars are just not worth the money and time required to make this conversion. He is currently undertaking a rebuild of the engine as the garage costs are astronomical and would easily have exceeded the value of the car.
When you removed the tensioner, did you rotate engine by hand or did you jog the starter? Perfection Auto Works is experienced in working with high mileage vehicles. This is how your engine manages the combustion and exhaust process. One of their mechanics is a Merc Specialist and it's him who's doing the work. I had issue with the cold start timing chain rattle year ago. The item must be new and in its original manufacturer packaging to be eligible for a cash refund. From what I could see, even if the crank pulley bolt has been removed, wouldn't it not make a difference since it has a notch for the pulley to slide in, making the position of the crank pulley only able to go in only one way? We were then able to fit the new timing chain. Really confused at the moment.
Today I will tackle the removal of the alternator to replace the timing chain tensioner and also the removal of the valve cover; however, I will not replace the tensioner until the new chain has been guided through. We unfortunately managed to break it when replacing the engine. Thanks Tony Smith Click to expand. Ever since I started the job, on Friday the engine has not been turned by the starter, it has all been rotated by hand by means of the crank pulley nut.

Sorry guys I have not been able to bring updates, currently stuck.
There is a plate over the oil pump drive pulley that prevents the tensioner for the oil pump chain being replaced. So here I amSomething is not right. I got the marks dead on and closed the timing chain and crimped the master link. You can always remove the bolt but will need an impact or hold the pulley in place while you do it. The engine oil pump drive is also an orthodox metal chain B These are examples of 'A' Class timing chains One is new the other well used, the arrow pointing to the severe wear of the used chain. If the timing chain itself breaks, a tow truck will be involved in the car repair process.
I have used this garage for years and trust them but thought I would double check if the cost seems reasonable? I think I was talking about the M272 but here are some of the pertinent docs for the M271. If it needs replacing then the air filter housing has to be removed to allow access, the tensioner is only held by two bolts and is easily replaced, the unit will need to be pushed down and held while the bolts are replaced and tightened. Luckily I hadn't crimped it. I keep running the pulley up to about 60 degrees and then the piston finally reaches the top. There are usually a few signs that the timing chain on your car should be replaced, some more subtle than others.
It's smart to test this part every so often, noting any damage or lack of proper tension. By taking the financial hit early you can avoid major engine damage which can cost thousands of dollars to repair. The cold start noise was similar, but much louder than this one. Ahhh - thanks for the info buddy - like i say no lights were on the only warning something was not quite right was just a rattle sound when the engine was idling that had become more consistent and louder over past 6 months ish.

Until recently, the vast majority of cars were built to use a timing belt instead of a timing chain. We have over lots of customer reviews on Mercedes Benz Timing Chain Tensioner to help you find exactly what you need. Timing chain fine, not stretched, guide rails fine as far as I can see, hard to say about tensioning but it looked ok to me. Could the new tensioner gone bad? This should have been a simple job but is starting to go south from here, loosing a little faith in this project. Using a was usually more cost effective than using a timing chain, with the only cars opting for the chain being higher-end sports cars. So I wasn't able to verify if the car had lost timing or not.
