M272 & M273 Engine -Balance Shaft Installation and Timing 

Great video for video for someone attempting this at home. I picked up a lot for myself. Few pointers from doing this myself. ( still in process....if it starts and runs... i'll post my /pictures/videos. ) 1.) Don't need to remove heads or covers to change out the Balance shaft. It's extra work but, not as much as cleaning and prepping heads and covers. 2.) If you do end up removing the heads for cleaning and or valve work, the chain will slip off of it's locations if it's not supported correctly when flipping the engine to it's upright position.

Wow , a very professional guide, god bless you sir. 10 out of 10.

Buenas noches Mr. Padilla. Este no es video común; este un verdadero tutorial para aprender. Gracias por compartirlo. Si le es posible subir otros similares lo apreciaré. También si le es posible poner los torque en No. felicitaciones.

just made this without removing engine from car :) balance shaft was ok. never again! thanks for video

Just spotted a few shortcuts, nice.

Thanks Eddie, this is very helpful

THANK YOU FOR THE GREAT TUITION ON THIS TYPE OF ENGINES. SOON I'LL BE REBUILDING MY 09 SLK 350 AND I NEEDED THIS GREAT INFO.

Great video. Not a bad job doing the balance shaft repair. The mercedes kit is quite comprehensive too. Just don't overlook a stretched timing chain too.

سلام سپاس تشکر درود و....هزاران 👍...🙏🙏🙏🙏🙏🙏👌👌👌👌👌👌👌👌❤❤❤❤ممنونم بزرگوار مهندس برلیانس عزیز

Very nice video 📹 and good explanation thanks very much for the the good job

Had the balance shaft start to go out on my 06 r350, so I got the engine from a 2010 GLK350 and replaced it, about to buy an 06 c350 with a bad engine, and replace the balance shaft on the m272 from my r350 and put it in there, I believe if I pin and remove the cam gears this should be a pretty straight forward job

I love this video! Very detail explanation!!! 👍👍👍

Thank you Eddie Padilla.

Hey!! Very good video... do you know if I need a specific mb scanner for the end to learn the new position of the camshaft at the computer of the car? I don’t know if there is a specific procedure with a computer... thanks for your help

Eddie, thanks from roy, perth western australia.

great work, M272 and M273 engines are the best once you get it right.

The comedic start was a riot 🤣🤣

Great video!

great set of videos nice find learning loads keep them coming thankyou new subscriber here ;-)

Really good video. Thank you.

Hi Eddie and thanks a lot Few people takes the effort to make a truly informative video. You refer to a previous video but I am unable to find it on youtube. Do you please have a link to that? Thank you

Thanks a lot for the great information

Excelente video amigo gracias

A perfect example of an over engineered engine Nothing's better than a good LT4 pushrod engine, light, simple, low center of gravity, dependable, easy to fix and mod and inexpensive parts, just to name a few of its advantages.

It's a good video. Thank you very much.

4 things in this video i have questions about 1) Why does the weight on the end of the balance shaft need to be replaced. Some say the shaft and the weight have to be matched. If that is so how is it that you can buy the weight separately? 2) The pulse wheels were to be replaced " because the pins/studs can be sheared off if used a 2nd time" . Don't understand that if the pins are still there and in tact and insert properly. The torque on these is enough to hold these pulse wheels in place. 3) The Chain Tentioner "Must" be replaced because it cannot be reset. Wrong, with a vice and some small tools it can be reset. 4) You must buy 20+ dollar sealer for the gaskets. This I can understand for the valve/cam cover because it has some technical issues (like holding the cam in place) that makes sense, but for the timing cover, pan , thermostat, water pump gasket it would seem that Aircraft Form a Gasket would work fine. This issue of always saying these MUST be replaced with no explanation is irritating and makes me think Mercedes just wants to make MORE money on the blunder they caused.

Wao...its a great work!

So I'm gonna be attempting to do this myself and what not, it's a personal project because it's my dads car and I want to make him proud of me so if there is anyone that is wiling to talk and assist I would love that much love to you all ❤❤

Very good videos

I'm convinced that this job is for a Mercedes qualified mechanic; not for home mechanic without proper Benz tools.

Wow nice explain

We need to torque them to specifications. Good idea but what are the specifications? I bought new bolts and the specifications that came with them say 1=20nm, 2=40nm, 3=90deg, 4=40nm, 5=90 deg, 6=90 deg. I don´t get it, after step 3 to torque to 40 is meaningless as the torque is already way above. Shall I loosen them and start all over again or what?

I have a m271cgi w204 his do you construct the engine,the value snapped and damaged the head and piston

Great videos with vivid clarity. I am looking forward to doing this job on my '07 Ml350. Can you or someone reading please help me with direction or manual on how to remove the engine from the car (from above). Thank you in advance and for this presentation.

Excellent Video

It's a good & useful video,so any other videos for M274 engine,tks!

great video. I fixed my car.

Awesome video,do you have one for the m112 engine?

❤ thanks so much

Great !

any idea where i could find something like this for the m111 engine ?

perfect

Bring back the old engines they were much better...

Hello thank you for that video. I'm building same engine so I get an issue the right side sprockets they not forming a line and all my marks in the crankshaft and the balance shaft and the left side sprocket they timed perfectly? And I am suspecting the right exhaust variable valve timing maybe it wound? Please can you tell me what do you think. by the way after pulling the crankshaft take the Slack easthill not forming a line.

Hey Eddie where u from my car is The same problem do you have a fixed

Very goood! Thx

thank u

How do I fix the balance shaft. It's just put in but I couldn't see fixing it on the back

How do we keep the timing chain in alignment on the crank and balance shaft after putting the front cover on?

Super Video

Interesting video. Cant help thinking, thats some fancy engineering for 250ish HP. Even if the reason is a smooth running motor it feels a bit overengineered?

cool

Please can you please upload the one of ML350 4matic V6 and CLA 250 4matic 4plugs

Good

Hi My 2006 C230 V6 2.5 M272 is making a constant ticking noise once the engine revs anything above idle. While driving the sound goes away if I take my foot of the accelerator. It sounds like the noise is coming from the left cylinder top, somewhere in the front. Does someone have an idea what could be the issue?

Hey thanks for great video!!! I do this on my V8 , everything goes well, except I can’t line up timing marks on camshafts perfectly. Copper links in place, but when I put all the gears together, marks are little off! I could not get a perfect line on all marks with the heads edges! Help!

I'm taking off my right cylinder head currently and i have taken out all of the cylinder head bolts, and i was wondering even if i hadn't taken off my exhaust manifold yet, shouldn't i still be still be able to lift my cylinder head? or is the only thing stopping me the exhaust manifold bolts

Is the Timing Crankshaft Gear typically changed when doing this repair?

just seeing this now i am interested in a 2006 c230, but my worries are after changing the camshaft balancer will it still need changing again after a while or it's a permanent solution.

Hi eddie, How much pressure are you putting to install the camshaft control valve exhaust? Im referring to 23:10 min in the video. Thanks!

Help! Please, First Thank you for the Video, Unfortunately like many videos the orientation of the Balance Sprocket is not specified. My 19 year old son have torn down his M273 in my work area and he has removed the carbon behind the rings and performed a valve job and now we are stuck reassembling. How does the Balance Sprocket go in in relation to the copper link on the chain. There are not three lines on our sprocket, just weights, a mark on the weight and a part number. Any help would be appreciated. Thank You!

Holy smokes, I did a OBD scan of a C230 I was looking at and got the P0016/P0017 codes and am glad I am now not going to buy the car... this looks like a multi-thousand dollar job.

Does any one know if the Balance Shaft Gear replacement part done at Mercedes is the same exact part or an improved version?

Is there a way to check balance shaft timing without removing the timing cover?. I'm replacing the cylinder head on the right bank and i'm paranoid that the chain might have skipped a tooth on the balance shaft.272 engine

JUST WENT THOUGH THIS, MBUSA COVERED 15% OF MY $6400 BILL ON MY 06 E350 WITH 44700 MILES

Ausgezeichnet 👍👍👍👍👍

I have a question for you. I have Mercedes Benz r350 v6 cylinder 6 has a misfire. I replaced the air intake manifold I saw the intake valve filled up with oil. There is a way I can fix valve stem seal without removing the head off. Please let me know the best option

Is Hylomar a good gasket material for this engine?

on what milage or km can one expect replacement? I have the new normal aspirated 5.5 V8, no turbos

What the cause of cutting timing chain after assembling engine and run for 30 to 50 second ? Is a worng or impropriety timing cinter Please any one help

Don’t forget to release the tensioner not doing this can cause damage to the valves .

Very usfull

Why do you put the timing cover on before the cam gears?

Thanks for showing the timing procedure. In M273 V8 engine there is no blance shaft because there is no need of balancin cross plane V8 with natural 90degree V angle, int this place there is only gear that tennsions timing chain. The balance shaft is only in M272 V6 engines whres Mercedes applied unnaturla V angle 90 degree and too soft steel for timming gears

Does any one know what size torx socket is used for the back of the camshaft?

Might as well rebuild the whole engine at this point. New bearings and rings would not add that much to the total cost. What the hell was MB thinking ? Thanks for the great video but no thanks MB , I think I will send my MB on down the road.

Can the old balance weight be reused?

What does this cost if this needs to be done? And does Mercedes cover any of this?

Where is the first video the narrator was talking about???

Can you do this job without pulling the motor?

Can this be done without pulling the engine?

Which years were affected by this issue?

Why did the heads have to come off? I’ve seen other videos where they do not have to come off

Hello I hope that someone can help me with this. When aligning the right intake camshaft sprocket the R with the arrow, would the arrow be in the middle of the copper link. Assuming the letter W would the arrow be in the middle of that W like V^V the symbol ^ would be the arrow that is at the end of the R.

Wow. I replaced a clutch in a Fiat Spyder when I was a kid and ah remember that the lowest point on that car was the oil pan only less than a foot from concrete. That was pretty simple but need to jack the engine up a bit to do it. This process is clearly beyond my tolerance level. It seems like the M272 is of poor design. Why would the chain hang in my opinion? The chain needs to react to stressors I assume but keeping it inline per a lifecycle of an engine seems poor design per my take on it. Yes, I have the M272 balance shaft repair per 77K miles on my SLK 350. I'm hoping MBUSA will do something. Its clearly a problem with that engine at that time. A class action suit was launched that paid for most repairs but I'm beyond the 10 year mark but with 77K miles. A 60K car should not be toast at 77K miles. It just seems to me that replacing the balance shaft would not repair damage made by metal fragments circulating throughout the engine. MB also suggested the same when I learned of the class action effort years ago. A new engine would be needed. They also suggested that we do not see many of those models around anymore.

At what miles does the balance shaft problem occur ? Somebody please help

I used this video for my guideline. i assemble a M272 engine with this guideline.. After done assembly, i'm it started and some knocking like misfiring happen. And a tapped sound rough just like a diesel engine.. Somebody please help me what should i do. TQ

hello My engine number is M272 30 660801, do I have to worry about balance shaft ? thank you

is it possible to do this balance shaft job without pulling the heads?

What's the specified torque?

My pet hate is silicone as a gasket. Just make a proper gasket!

Was quoted $2800 with parts and labor for this repair. Anybody else? What do you think eddie good price? Mines a 6 speed c350. Mechanic suggested just replacing the balance shaft instead of buying another engine. Sitting at 150k miles

I wondered why resale dropped so so much in their suvs. People are selling these, knowing the problem is there... not informing people.

Is this happened because of code P0012?

get a whole new engine

Have to take the heads off?
