Mercedes Benz Timing Chain Tensioner can be reused. In the above video I explain how. Part no.: A 271 050 09 11 For more info contact Iqbal Aniff email: mototech@mweb.co.za
Thank you so much I'm so happy you're intelligent enough to be so patient to explain it to people like me at the door trying to get my car fixed I'm so over watching videos about obnoxious intelligent people being rude and suggesting that everything you do is a waste of time but spent $3,000 on the engine they have no empathy for people who are just trying to get by I really appreciate this video I'm going to try it and I'll reply if it works
you are a real engineer! thank you very much! from Mexico. Mercedes really lost a lot of confidence this time. Their company inside problems really took a lot of people money and trust.
thank you sir. I needed to reuse new tensioner and I was thinking of buying another new one but after watching this video I successfully reset the tensioner.
Thank you very much! I just did mine and works rather well. I found if you hear the first click your ok but if you keep pushing till the second one then your too far. The second click is the sound of the snap ring passing over its proper spot and onto the second hole. Anyway works well, good trick. I like saving money!
Thanks for the video - how do you access the tensioner on the W168 - just remove the airbox or is there more to remove? Any precautions, or simply remove and refit?
Thank you John If you planning doing a timing chain replacement then I would advise you to read my reply to Sergey Kravtsov. It would make your task much easier. Good luck
@@iqbalaniff1650 Hi Iqbal, I have read your reply to Sergey , and have taken note of your advice. My engine is a W201 1987, I replaced the chain tensioner today, and discovered that it of a different design to the one in your video. It is simpler to set it back to zero position. I have the engine stripped down, although it is still in the car. The cylinder head is removed, and the pistons out of the block. Tomorrow I am going to feed new timing chain through the guides.
Thanks for the video! Once you return it back to its original position, do you just install it? How does one ensure the tensioner is properly installed? I screwed my tensioner back into its bracket but don’t know if there is anything else that should be done. Have searched everywhere for proper installation instructions but no luck
hi All you have to do is tighten the tension and once that is tight then you need to turn the engine anti clockwise approximately 90 degrees at the crankshaft pulley bolt to activate the tension. If you listen carefully you will hear the tension plunger move forward. The plunger part must move forward and touch the tensioner rail so that there is always tension on the rail pushing the chain. This is the most important part because most people do not check if the actual plunger came out. You can read comments of mine to other people that will probably help as well.
No it will not It is best you change the timing chain,tensioner,guides and gears all together also an oil change with filter is essential. From my experience I have discovered that 5W40 fully synthetic engine oil works best on these engines. Hope this helps
It always best to replace all the timing chain components when doing a vehicle with high mileage however if you want to save money and do a repair on a budget then inspect and replace just the parts that needs replacing but the timing chain must always be replaced.
Hi Sergey That is correct and an important step is to release the tensioner - you must turn the engine 90 degrees anti clockwise and then back to TDC (if you listen carefully you will hear the tensioner release thereafter turn the engine 3 full turns clockwise and make sure your timing marks are aligned. Just a word of caution please do not take the O/T (TDC )mark on the crank pulley to be correct. I have had issues with the damper pulley moving on the rubber mounting. Remove the number one spark plug and put a long screwdriver and double check if the crank pulley damper is correct. Good luck.
I am just pleased that people know the procedure and not spend money on purchasing a new tensioner. The rest is up to them how they go about doing it and their level of mechanical experience. Regards
Sorry my friend couldn't quite hear what you were trying to explain, as far as I could make out you were finding it very difficult to release the cir clip?.??
Can any one tell me why it is nessesary to have that locking feature in the tensioner. if it is constantly pushing out (towards the chain) why woudl there be any reason to lock it from going back?
Let's begin with a newly installed chain & tensioner. The tensioner is used to put tension on the chain to prevent skipping as the chain [ and engine ] accelerates and de-accelerate as you drive. With use and wear the chain gets longer, you want the tensioner to snap out [ longer ] to take up the slack, Also on starting and heavy acceleration or de-acceleration you don't want the forces to retract the tensioner. .
When the car is accelerating the crankshaft below, is pulling and tugging on the camshaft above, to operate the valves. when you take your foot of the gas, the Crankshaft slows down first pulling and tugging on the opposite side of the chain where the tensioner is located.[ it's like riding a bike with a fixed gear sprocket ] Without the locking mechanism, the tensioner would collapse [ get shorter ] and the chain can skip.
Good video and smart man, but honestly don’t risk it and just buy a new one. I reused my tensioner and a year later caused major engine issue because apparently it was never deployed/released. It was jammed.
always when you change the chain you put on a new tensioner. This is drusety not repair and no mechanics are used in workshops unless someone alone but do you spend a lot of 30 euros on the tensioner
NO...it's perfectly designed...one time use so you will have to buy another $130 tensioner...and you can't complain if you put a used tensioner in and it fails
