Out of frustration, I tried to find his supervisor. When you removed the tensioner, did you rotate engine by hand or did you jog the starter? The chain is a duplex chain type, and is completely different to the original chains that were fitted. Once that happened I brought in the new timing chain tensioner in and tried rotating. Would a late 85 W123 230 be double? The marks all line up. Not sure if it actually is.
Sounds like should be about 60deg off one way or another from what your saying. The greatest issue I see here is that once I get to 0 on the crank pulley, the piston is still not at the top. First thing is I would buy a workshop manual to help me do the job but I only have macs at home and at work and the manuals are only windows based, so I can not read them. Ernie 46000 miles and a duplex chain is worn, or tensioner warn - something not right here. Can anyone give me details of how I should go about changing the adjuster and guides please. If in fact, I had to take my vehicle to benz dealership for any repairs to get better service discount, I would have taken it to benz dealership. Unscrew chain tensioner housing from timing case cover.
I will not use the chain breaker used by mercedes, instead I plan on using a dremel with a steel bit to remove the lock pin. 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. M I wonder if anyone Aprilia? There reasoning is that I did not use a mb oil filter; they have cancelled my warranty. A lot of mechanics don't check the timing chain during the valve adjust unless you specifically ask them to. Now I am driving this vehicle with the check engine light on because of the problem I mention above.
Thanks Tony Smith No, steps for Engine 272. M Tue 28 Oct 2003 10:30 Mercedes Timing Chains. Although generally speaking timing chains will make a bit of noise as they stretch and wear, basically they get loose and rattly but it is not unknown for chains to snap without warning. All the old Mers used to have the chains joined this way. The crank pulley and the cams have to be moved in sync to feed the chain. That tells you something surely. Could it be possible that when I was rotating the crank the valves were at their highest point? Now the chain seems very tight and there is a loud whining noise when you start the engine.
After using a 15mm open end wrench remove the bolt holding the positive connector. I have c180 06 kompressor. A quick 'bodge' would be to cut the chain as you describe and feed another one through, then swap the tensioner. Jpman, did you check if the key-hole is opposite the O T mark on the pulley? Car has been booked in, will be getting a new timing chain on the 5th of January. By the way, If its worth mentioning I measured the distance across both chains and it seems that if the old one was stretched it wasn't by more one fourth of an inch. Leaking oil from either of these three items has been known to collect on the serpentine belt and in turn be transferred to the harmonizer. Otherwise it is sorta what you are willing to live with.
So best to keep on top of it. There is only one sprocket design for these engines so I am sure the chain is going to be ok. These last about 100k mi. You let the cams go all together correct? How would you feel if we said don't worry about it and then something happened, well that's why it's best to give a conservative answer or no answer because there is no real answer to the question of when should a timing chain in a M104 motor be replaced. I'd rather pay now than worry about it happening in future as I hope to keep the car for a good few years doing 8-10k miles a year. While attempting to start the vehicle, the contact noted a choking and knocking sound in the engine. Thanks My dad did his himself wasn't easy.
Having us replace a tensioner, pulley, guide or even chain is significantly less expensive than a complete engine overhaul that may be necessary if your Mercedes timing chain fails at high speed. The Mercedes-Benz Owners is a completely independent organisation. It was like that before is what I am willing to bet. My 1997 E320 has just done 200,000k. It is the cam chain.
The Turbo models will be a problem in the future believe me, as mine is now. But maybe they included for gasket kit also. Next time make a point to ask them not only to check it, but to tell you the number of degrees the chain is stretched. Car is just 5 years old and I can't believe it has this problem either. However, because timing chains are lubricated by the engine oil, their level of wear can vary depending on how well serviced the vehicle is. 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. Most qualified mechanics will be able to perform a timing chain replacement.
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? Same here about any previous chain replacement in my M112. Are you sure the cam chain etc is the actual problem? I never felt resistance rotating the crank, at least not as much as what I feel now. The manufacturer was not contacted. The Febi parts I take it are copies of the original parts and not any modified Merc parts. Taking advice there seems to be a fair difference in the repairs folks would do.
