MERCEDES M272 and M273: BALANCE SHAFT SPROCKET REPLACEMENT

[@victorabdulai8650]

Very educative videos especially for us in Africa

[@codileecaldwell430]

Got ripped off by a car salesman selling me a 2007 slk280 with this problem, he sold it to me through craigslist and got me good for $7,000. Tom spires at an Ohio dealership

[@jgonzalesm6]

Certain years of the M272(V6) & M273(V8) had the inferior balance shaft sprocket. MB got sued for this. First, you must get the VMI(vehicle motor inquiry) from the dealership...this is free and should'nt give you any issues. On the VMI sheet is the engine #. If your engine # is above or higher than the engine #'s with the faulty balance shaft sprocket, then you're good and have the updated balance shaft sprocket. Otherwise, you're going to have expensive issues down the road with faulty engine codes first, then IF not fixed, the engine gets rough and after 20k miles of NOT fixing it, you run the risk of the teeth jumping, valves bent, and a complete engine rebuild....around $15k.

[@WhiteXKnightz]

joe r gonzales are you saying that there Is a way to get this repaired by Mercedes dealer?

[@OrangePopOtter]

I am at the step where you open the hood but confused by the rest of the video. Uhm... I think I am just going to trade it out for a miata.

[@cristianbustos4918]

balance shafts are a piece off cake!!!!!!!!!!!!!!!!!!!!!

[@ferdelolmopersonal9100]

Ojalá hubiera visto este video antes, en Mexico me costo mucho trabajo quien supiera reemplazar la cadena de distribución rota y el Shaft balancer. Creo es un problema bastante común en este motor

[@mohammad45h]

سلام سپاس تشکر درود وهزاران 👍..thank you very much You are berelians ...👌👌👌🙏🙏🙏❤❤❤❤❤

[@glasser2819]

no wonder Benz stop using reliable timing belts... now they can make soft timing chain sprocket: genius 👍🏻 The engineers that went out of their ways to specify tin-can steel knew exactly what would happen... good match with the vinyl seats 😂

[@fakenews3676]

Mercedes has never used timing belts.😂

[@HotShotHaven]

Must also replace all oil pump related parts and also check the cylinder walls for scratches. Glad mb fixed this issue. Really gave them a bad name for a while

[@rusty358]

Still does!!

[@kito1san]

I heard Mercedes lost the lawsuit on this issue. A campaign will be coming out for this repair. Its not free, but looks like they will pay half of the cost.. Well see whats to happen.

[@huthaifamali3212]

Any links on the matter?

[@ZZZiemniak]

Czy wiadomo już coś?

[@bobl78]

do this and that and this and that... it would be faster to install a new engine

[@kito1san]

But that would be no fun. Mb made this issue so you can have fun fixing it and like in Russia, you don't fix engine, engine fix you.

[@zambuzan]

@@kito1san LMAO

[@michaelric3540]

If you’ve maintained your car well it’s probably better to repair the motor. You never know what you’re getting with a used engine.

[@craigkeller]

With all the MB engineering that’s been invested they couldn’t make it far more complicated? Shame.

[@ruhsatigoek1632]

Very good video

[@localsource]

Help! How to position balance sprocket M273, Small mark on weight versus copper link on chain?everything explains 272 balance shaft, but i need info on 273 Balance sprocket. Thanks

[@Visionery1]

Damn, this is going to be expensive, especially since my engine won't be out of the car. The big question, is the replacement gear improved or simply a replacement of the original?

[@nunosousa4689]

its a reinforced gear, so no more wear

[@roadwarrior144]

This video shows how utterly easy all of this is. I'll bet the people who dictate the ASRA labor times for this procedure are watching this video and saying to themselves, "Yea, the repair for this should only take an hour and a half or so! Look how easy this all is to take apart!" and us MB technicians take a hit in our pay. I hate engineers, who've never held a wrench a day in their life, tell us how long it takes to do our jobs. And they say things like "It worked when we simulated it in CAD!"

[@MissionaryForMexico]

This video is for teaching brain dead idiots. Also for people that cannot visual work involved! It has absolutely nothing to do with engineer's!

[@joserasak]

customers should not pay to fix Daimer mistakes. when we pay 100.000 euros for a car, we expect the best or nothing and this is not correct. i had similar problem on my 2006 SL 350.

[@p3sg-pennsylvaniapowerllc359]

Time Bombs..... Also suffered with the biodegradable wire harness on the W124. My last MB

[@marc7983]

a wiring harness is nothin compared to this. A relatively cheap repair to a great model. What you driving now that is sooo great, you've had for a long time and spent no money on?

[@riekful]

Dealer won't do this test, they said I don't need these because the obd says it's only a sensor

[@Lonely_Benzer]

Engine check light can cause several problems. So obd check is always essential

[@sylwsmith1218]

gear wheel made from chewing gum last mb quality

[@hasanisadickhamisi5966]

good

[@vwkingla619]

Looks like this job can be done without pulling the motor.

[@eurowerx4267]

oil pan must be removed. try sliding it back without doing so, youre gonna pinch head gaskets

[@ferdelolmopersonal9100]

Ojalá hubiera viste este video antes 😭😭😭 tuve que pagar mucho dinero para que repararan mi Cadena y aún no queda, los mecánicos destruyeron más cosas

[@jimmybaggs5342]

03:22? Why would you have to replace the entire cylinder head just because you damage the valve cover?

[@nelias7306]

This is because the valve covers have the upper cam bearing journals built right into them so they are part of the camshaft. They cannot be mixed and matched or seizing and galling may occur

[@nelias7306]

So in a nutshell the cam bearing caps and valve cover are one piece

[@jimmybaggs5342]

nelias7306 Damn, good to know. Thanks for the reply.

[@nelias7306]

Jimmy Baggs no problem. There is also a very specific tightening sequence that needs to be followed for the valve covers because of it

[@mechanicimrankhan6763]

Because if u buy new valve cover will not mach with sylinder head

[@derekkchung]

About to buy a used 2006 ML350. I know, from checking the engine serial number, how to tell if the shaft is a problematic one. But how do I know if it was replaced by mercedes (they have centralized records?) or an independent shop ?

[@srm113k]

There was a bulletin that came out in 2016. See: australiancar.reviews/mercedesbenz_M272.php M272 and M273 engines prior to October 2006 have this problem. I have this engine 😂

[@jason.arthur.taylor]

You need ask to see the dealer's VMI report for that vin. It's in their computer for their eyes only, though. (Fear it would be used to sue them.)

[@kito1san]

@@jason.arthur.taylor nah. There is a link that you can get this info. Decoded from the vin# of your car. Pretty good data base on the vin #. You can then find the engine number and see if your vehicle falls in the issue range.

[@mybuilds]

Anyone know how the timing case magically removes itself?

[@mortenmorfar]

With a big hammer, this engine is so stupidly designed, to remove the balance shaft you have to remove the transmission and rear main seal, and to replace the rear main seal, you have to remove the second lower half of the engine, because there are 2 bolts going from there up into the seal, why ?, because Mercedes Benz, everything on that engine is just stupid, to remove one thing you have to remove two other things :/

[@przemkok6015]

Hahaha!!! Tak łatwo to wygląda na tym silniku który nie jest poklejony na masę uszczelniającą. Niech nikt nie liczy że w praktyce będzie to takie łatwe.

[@rusty358]

Shifted cams may indicate a stretched chain, not necessarily a worn sprocket on the balance shaft. Replacing the chain and tensioner may fix it and reduce the wear on the balance shaft sprocket.

[@jackkallemdjian3945]

I can't believe Mercedes engines have this fault, wouldn't touch one now was interested in a v6 clk not now!

[@zxtenn]

Yes, a VERY bad design and VERY expensive to repair, I was told on the ML that the engine needs to be removed, not much reliability at all especially for such an expensive car

[@Lonely_Benzer]

Same here. Luckily i got the 320 Model in my E Class. The old 350 V6 engines until 2004 also have this fault

[@zambuzan]

Yeah I thought the C300 with a stick would be a pretty cool car... now from seeing this video, I am running!

[@dfweurocars]

Oscar Rodriguez just get one from 2010+ they fixed this issue..

[@akujude]

@@dfweurocars so 2010 has the same issue?

[@gearhead3500]

HONDA KSERIES FOR THE WIN

[@erickcontreras637]

Just made to generate owner expense

[@kristiankumanov5732]

So, those pigs knew about the ticking bomb, especially the M272... Anyway they continue to build MB with those engines for years...They made Recall too late, after customers in USA started case against MB...It was too late, because the dead line for this recall was too short...

[@mbmann3892]

1:03 and 1:12 does anyone see the difference. I don’t

[@WR-nl2wd]

The stamped markings are NOT centered in the visible aperture. They BOTH should be visible in the center and NOT offset.

[@tvs3497]

The electric powered auto should have replaced the internal combustion engine 4 generations ago. As a member of the human race, we are something else.

[@gfhfmf]

The only mistake of Mercedes-benz made was this M272 and M271 engines...

[@elviejon84ful]

gfhfmf any idea what years are afected?

[@TheRealYaar]

@@elviejon84ful multiple models, s550, clk, cls....i know s550 anything 2008 model and later is fine.

[@alextorkelson6261]

Not the M273 V8?

[@kito1san]

Looks like pretty much all models from the years of 2004 to 2008. They finally got their act together and fixed the problem after 2008.

[@maliekmills457]

M271 engine is not comparable to the failure of early M272 engines, these two are completely different in terms of their reliability and issues. The M272 balance shaft issue is far more expensive and complicated to rectify. Hence you don't see many of them with mega milage past 100k, at least in the UK anyway. Although enthusiasts slander the M271 engine for having a single row timing chain, few of them do actually go when maintained properly with correct oil, servicing etc... Many have documented exceeding 200k miles with their M271 engine on the original chain. My C180k coupe is on 112k miles and still drives well, haven't encountered any issues with the chain. Other than vacuum leaks from Kompressor hose, I've not encountered any significant engine problems and the car has been in my family since 2008, so the M271 seems pretty solid imo.

[@riceball4u172]

Piece of sh!ttt design and MB won't take responsibility for any of it. This is NOT the only known defects. Intake manifold runner controller (using Cheap plastic instead of metal), conductor's plate (cheap plastic break), balance shaft (not heat treated correctly), Secondary intake pump and relay will break every 2 years (draw too much power for the relay to handle)! Rusted Rear subframe! that's all the problem I experience so far.

[@EpicMadnessxx]

My guy can fix a motor but not that haircut?

[@lancelotlalla7561]

This is why I drive a Japanese car LMAO!!!!!

[@jasonthorogood]

Honda?

[@maxpayne044]

Why in the world would anyone buy this junk motor?

[@jason.arthur.taylor]

To get laid.

[@kito1san]

To get a full experience of the engine assembly down to the basic. In the end, to replace a low cost part. The labor is the killer. Funny how this hard to get to part requires so much disassemble and damages/contaminated to associated parts.
