Hello guys. In this videos I want to share with you how I replace the timing chain & cam adjuster kit on Mercedes Benz M271 engine. There are 2 known reasons to timing chain and cam adjuster kit, one the engine rattling on cold start and other reason the engine has delay starting. I hope that this video would help you out on how to remove and install the on your timing chain & cam adjuster kit on Mercedes Benz M271 engine.
If you found the the video is helpful, please don't forget to subscribe for more videos. Thanks for watching!
Drop the sump - slacken the bolts and allow the front to move downwards 1 or 2mm - and remove the front timing cover. Then you can remove and replace the chain whole. Note that the original 2003 M271 (W203) camshaft sprocket design is different.
Tener, encueta!
Спасибо единственный из миллионов видео на ютубе показал как одевают цепь на звезды и сравнивает по меткам красава
Came here for timing chain stayed for the music
That' my tast.
I was watching this video & noticed that part of the chain link was dropped on around number 2 spark plugs area. Around 2:26 part of the video. Did you ever remove that? Or did you ever find it? It could do some damage on that engine. Watch your video and you’ll see it.
I did removed it.
haha i guess you are a mechanic too .... i see it ....and stop the video and go back to look again wit 0.25 :D good eye bro
Thank you 🙏
You are welcome
Hello, how are you? I am a loyal follower of your channel,I had a question about replacing the timing chain,Here you have the engine turning without releasing the camshafts, right?I mean, the valves aren't all closed, some of them are still open. Don't you think there's a danger that one or another valve in the piston could come into contact?I mean when you pull the timing chain through you have to turn the engine and then the valves or pistons will be damaged.I would love to receive your feedback.
No. Valves and pistons shouldn't be hitting at anytime. If any valve and piston makes contact with each other at any point, there is a problem.
And the ONLY time that valves and pistons are hitting each other when the engine is not in time.
Isn't this an interference engine? The piston won't touch one of the valve?
Which timing chain kit/ajusters brand do you recommend ? Since oem go bad i think better to go with somthing like febi.
Thanks for the video. Piston # 1 will reach TDC twice in a cycle. Once it will be at the point of ignition and once at the end of exhaust. At which TDC should we lock the cams?
The lines on the camshaft/camshaft housing and "OT" mark will all align only on every second turn of the crankshaft, right?
Yes
Please my new updated that would help a lot.
I think timing chain and camshaft issues caused by hard driving and driving like a racecar, extreme pressure on chain and camshaft. If you drive and accelerate normally the timing chain should last. just my guess.
If only sprockets are damaged, do you have to change the whole timing kit?
The whole kit.
Top part of this engine looks very clean. Oil changed at every 6000 miles?. How many miles was the old chain in this engine before this replacement job?. Not too bad if it had done 100,000 miles or more. Regards.
I would recommend to replace when the symptom occurs is the best way to do it
Hello, our cam and cam adjuster timing marks are off on our m271 engine, and cam adjuster is making a popping noise when I spin crank over by hand.
Is this the cam adjuster with the m271 that is bad? If yes, replace both cam adjuster while there, chain, tensioner and guides...correct?
Thanks
Replaced both adjusters, timing chain, and crankshaft sprocket should fix the car.
My timing marks are off on the cams. I turned the crank by hand and I can see the chain jump. The car previously ran before we took it to the mechanic and said the amount of work needed wasn't worth it. He wants to remove the front timing cover which might result in a front subframe lowering for oil pan removal. I just want to install a chain.
Could I (in this order)
1 Remove the cam cover
2 Remove the chain tensioner
3 Lift the chain off the cams
4 Spin the cams carefully (clockwise or counterclockwise) back to the correct line up assuming I don't touch a piston
5 Lock the cams with the MB tool cam locker as seen in your video
6 roll a new chain on
7 carry on back to the similar steps as seen in your video.
Am i missing some random top dead center on cylinder 1?
No, no, on, that's absolute nonsense. It's very easy to set the timing on this engine. No need to do all things that your mechanic said to do. First of all, remove valve cover, front cover, break old chain, connect new one, rail it in, connect new chain together with proper tool, turn engine to top death center, make sure piston #1 on it compression stroke, both cam shafts set correctly with proper Mercedes hold down tool and you're good to go. Put everything in the reverse order and you're done. Hurray!!!
@@MercedesBenzTipsTricks Thank you
Apakah sehabis ganti chain tensioner oli mesin diganti?kelihatanya tadi water collent masuk pada bagian oli mesin.
Hi, when you added the tensioner bolt, did the crankshaft spin about 10 degrees past OT? Mine does and it throws off the timing. If it did it in your case, how did you solve that issue? thanks
Good day I as a question if this engine timming chain as a failure does it bend valve or what damage can occur
Yes. Definitely, it'll bend valves or even broken valves.
It deoends on the type of engine. if its interference engine you can have damaged vaves. if its non interference engine than no issues even if the chain breaks in the middle of driving. the only issue will be that you wont be able to drive untill the chain is fixed. BTW I bekive this is a non interference engine.
Usually when replacing the m271 timing chain, do i need to replace the chain guide rail and tensioner ?
Yes.
@@MercedesBenzTipsTricks can the replacing the chain guide be done like in your video without removing lower cover and oil sump ?
Is it 100% necessary to smash the pins end of the joining link? Idk how to do it atm, i just installed the new chain, but that's the only thing im missing
2:25 did just something fall in the cylinder head ? :(
9:42 “Ooooohhh” muted because the effort. On the background a guitar playing a depressive and melancholic song. The misery of the human condition!
Oem set ? Should I go for febi or swag timing set?
OEM
On a 2012 Mercedes Benz, C200. When changing the timing chain kit, is the entire engine removed from the car?
No. This is very easy to do.
@@MercedesBenzTipsTricks Thanks.
How is it that you are not hitting the valves when rotating the engine so much??
Set piston #1 at top death center (TDC) and disconnect the timing chain from cylinder head and you can rotate the crank shaft all day without piston hitting the valves.
When it at its correct timing, the tool is use to lock the two cam shafts at the #1 piston top death center not on the exhaust stroke. You can rotate the engine forever. That mean all valves are closed for firing.
What do you do to turn the engine without hitting the valves?
what you mean?
@@siwysie Firs table, removed valve cover, removed spark plugs, set timing on Top Death Center (TDC) # piston 1 at DTC, use special tool to lock cam shafts, removed chain tensioner, disconnect old timing chain, connect new chain, feed new chain, replace adjusters, install chain back on adjusters, reinstall chain tensioner, reinstall everything back, done.
use special tool to lock cam shafts so none of the valves are completely open. You will notice this tool in video : the allu "bridge" across the 1st cylinder
@@MercedesBenzTipsTricks hi, when do you reinstall tensioner?
Did you reset the tensioner or using new every time ?
@@serjie567 The best way to do it to replace the new tensioner. We install the chain tensioner after the timing chain and adjusters are installed and time correctly and then install a new chain tensioner.
How much is a job like this.?
It’s depends where you bring your car to for repairs.
Do you know the construction material for the camshaft adjusters?
At the moment. no.
Bonsoir
How do i know when to change the timing chain?? I'm about to get a C250 with 62,000 miles on it, should i be worried??
You'll have a delay starting symptom or rattling noise.
On a cold start you’ll hear rattling noise like a diesel car for like 3 seconds and then it goes away. You should be worried once it hits 75-80k miles if you are taking care of the engine and chaning oil and doing decent maintanance
@@maikelelelelelel8875
I just bought a 2012 mercedes c250 sport with 62 k miles and now I hear rattling noise when starting engine.
Would you pls do a video if any of your customer did ask you to pull in a 12V based pressure sending unit, for a M271 engine, back onto top of dashboard. 😁😁😁. Thanks in advance. BTW, for pre 2009 M271 engine many of us here install "short pig tails wiring adaptor " at the outlet of both cam magnets so that no engine oil will traveled into ECU. Is this necessary for M271 Evo engine?. Regards.
@@whlawson5812 Yes, I would do it one for my friend
How much is a job like this?
And is P0430 related?
No.
i do not know if you competent enough to do this job. sorry
Thanks for your comment. I hope can do better next time
Good gob
Thanks
