Timing chain replacement

[@ronalddean3630]

Hi Pierre, this was great and thanks for sharing the job. The timing chain on my dad's 300SEL broke while we were on a family vacation some years ago. Our mechanic Duane, at the time drove all the way up from Chantilly Virginia to bring the chain and change in at the local shop in PA where we had spent the night. I have been following your channel since last night (7/23). Truly enjoying becoming more educated about all of these cars because I am in the market for another vehicle; just don't know which one yet. Leaning far towards a 560SL, but I would miss having a diesel engine --I have a '85 123 Estate Wagon. Question on the timing chain: In another video you mention the 380SL having a single row timing chain, whereas on the 560SL, I have an image on a cracked valve cover from a forum where the discussion thread was about 560SLs, and the owner complained about "ticking or knocking" sounds. He says it wasn't the timing chain, as it was stretched at 6 degrees. It had two chains (double). What did the cracked valve result from? Bent valves, or a broken guide? How can you stretch metal configured into a chain? Others say to always have the single timing chain converted to a double. Is double better due to the weight of the V8 engine? Thanks

[@mohabatkhanmalak1161]

Thumbs up!! Reminds me, years ago I changed the timing chain on my 280S, W116 - and what a sweet engine that was!!

[@mercedesclassicswithpierre1753]

that's wonderful! good work!

[@Rnara21213]

I spend ages going through your channel to watch every video! your fantastic Pierre. There are a lot of people that get a lot of joy out of your videos and knowledge sharing. please don't ever stop doing what you are doing!

[@mercedesclassicswithpierre1753]

haha not until i am dead!

[@LilyoftheValeyrising]

Wow! When this was filmed 500 subscribers! Now it’s 9,000 plus! Congratulations! I watch all the videos even if it’s not specific to my cars. I learn something every time.

[@mercedesclassicswithpierre1753]

Maria, this channel would be so much less interesting without your comments. keep guiding me in the right direction!

[@LilyoftheValeyrising]

Mercedes Classic with Pierre Hedary I know a good thing when I see it. 👍🏻

[@craigkeller]

Something about carborundum grit from your grinding disc leaves me uneasy. Just me thinking again.

[@frazierfrazierr]

I can understand taking out the plugs, but why the rocker arms? Did this on my 380sl and removed neither. Just had a friend hold the old chain to keep it from falling into the engine. It was a bit spooky when the cam for cylinders 1-4 jumped, but I just kept releasable zip ties on the chain/cam to keep it from jumping. Easy peasy!

[@mercedesclassicswithpierre1753]

the rocker arms are removed so you don't bend a valve.

[@bikeman123]

Is there any point rolling a new chain through, presumably to avoid replacing the sprockets? The new chain will just wear quickly without new sprokets.

[@vitalmakhdum]

Love this channel. Useful for when i redo my w108.

[@bobobobo1646]

Hello Pierre , thank you for the video fantastic . Just a question you didn’t change the chain guide on this car ? Thank you regards bobo

[@Mercmad]

oh dear, no need to use the disc grinder to cut the chain off. I just use a sharpened screw driver between the side plate and a link ,pop the sideplate off the chain by giving it a whack with a small hammer . . A rag or two stops the side plate or link dropping into the engine .No need for a fancy chain tool or grinder feeding grit into a customers engine. Cam wear is caused by not changing oil occasionally ,the feed is from the rear of the block and is quite small . If the engine is getting 'tappety' it's time to look at the cam oiling. I never change just the chain because it is the left hand inner tensioner rail which fails, gets fed around the cam wheel and bang... no more left bank. The rails are dirt cheap and take minutes to change once the ancillary's are out of the way.

[@laythalkhayyat9981]

Mike makes very load tick from the cam area, where should I start from

[@tonyvenn2467]

W108 250S. Have you ever converted a timing chain tensioner to a manual tensioner/adjuster? It would appear to me to not too difficult. Care would be needed when "feeling" the initial tension. Your thoughts please. Tony. Australia.

[@daibhidepaor]

Another great video. And I hope 2017 is a great year.

[@ricardocalles140]

The tough job is removing the timing cover in order to replace the lower guide rails.

[@AngelTavarez-x4q]

But this gay won’t show it

[@lowredeyes2155]

Dean is a wild man

[@jocrp6]

I've done quite a few of those in the day,,, They make a plastic tool that bolts on the front cam tower so you don't need a number 2 to help.

[@mercedesclassicswithpierre1753]

haha...I did end up buying that tool, but I also wanted to show people how it would have to be done if one did not have the tool.

[@jocrp6]

Any good info on 129/119 cars early 90's on the TPS/throttle/cruise control electric motors and that set up?

[@mercedesclassicswithpierre1753]

well, I guess it would make a good topic. if there is an ASR light that magically appears, you likely have an issue with the Throttle actuator or harness.

[@MrJearley6]

Thank you for this video !!! I learned a lot !! Thank you Sir!!

[@12pagani]

Ok this reminds me that I should do the chain and guides in my 89 560 sel. But how do you do the lower chain guides if you have to take the heads off to remove the timing cover off?

[@mercedesclassicswithpierre1753]

well, you can either pull the heads or the oil pan. Lower chain guide failure is fairly rare though.

[@12pagani]

Mercedes Classic with Pierre Hedary so just chain and upper guides? So raise the engine and drop the pan to do lower guides and oil pump chain guide as well if I'm in there. Again thank you

[@limpdependence1]

Great video, just discovered your channel. You've got a new subscriber!

[@mercedesclassicswithpierre1753]

We really appreciate you limpdependence1 for viewing our videos and leaving a comment. I tried to read as many as I can and take your responses for consideration on future videos. Thomas Polk KZbin Creator.

[@pewdiepieDL3]

This was the day you spoke about 500 subscribers. And guess what?? I knew it’s gonna double over and over

[@rusty358]

Can you use this technique on a M272?

[@jasonbirch1182]

Congratulations on the success!! Happy about 500 subs then!!! Can we get a non-acid flashback inducing MERCEDES BENZ TIMING CHAIN & GUIDE RAIL & TENSIONER REPLACEMENT edit for 25,000 subs? 😂🤣😂

[@JP-ek2bq]

What is the recommended interval to change the upper chain guide rails

[@DIYDanCars]

I'm going to look at a 86 560SEC today. Is rolling the new chain by connecting it to the old one the only way to install the timing chain on these cars? Is there not a timing cover than can be removed on the front of the engine that will reveal the whole chain? Nice video!

[@mercedesclassicswithpierre1753]

there is a timing cover, but removing it requires taking off the oil pn and both cylinder heads....we usually only pull the cover when the engine is coming out for major service!

[@tischlerbmw21]

How much quieter was the engine after the timing chain was replaced.

[@mercedesclassicswithpierre1753]

Well, it wasn't quieter but it ran better, especially at idle.

[@TheMr806]

How do you fix the timing chain win it jumped time

[@mercedes-mark]

I have a dilemma.. my 1987 560SEL has a slightly rough running engine... it happened all of a sudden. The tachometer jumps constantly which is odd.. I replaced plugs... wires.. fuel pumps.. fuel distributor. all vaccum parts are new. I need your help desperately.. could it be timing? or a bad ICU??? please help. thank you so much.

[@ChristopheZ]

HI, I was wondering if you found out what your problem was......I had a idling problem as well, and it turned out that it was my throttle body!!! ( I have a 1993 400E with the M119 V8 engine)

[@robbie3304]

Couldn't really see what you were doing

[@sockpuppets7256]

could possibly be your crank position sensor if you gotta tach jumping around. could just be out of range and moved closer to the flywheel ring

[@clandobrownlee4950]

Great video I'm having an issue with my 1990 300SE runs great except it has a slight dead spot at the initial acceleration it seemed to be a little more pronounced after putting a new rear muffler on appreciate any help you can give me.

[@mercedesclassicswithpierre1753]

your EHA is out of adjustment. Remove it and remove the slotted screw plug. take a 2mm allen and turn the adjustment screw, underneath the plug, 1.8 turn inward.

[@speeddemon002]

Great video!! I wonder how this works the change of a timing chain on a 300sd do you have to adjust the injector pump? Or just sync the pump with the new chain? Also please very important to me do you recommend the use of liqui moly mos2 anti friction oil additive and the engine oil flush from liqui moly on a 300sd?

[@mercedesclassicswithpierre1753]

it's a good idea. we use a timing indicator light - colloquially known as an AB light- to check pump timing. But due to the design of the chain path, they can't actually jump timing during a chain replacement.

[@mercedesclassicswithpierre1753]

liqui-moly products are great! But they aren't a total requirement

[@speeddemon002]

Thanks for the advice!

[@jamesjones4062]

Ytop plastic replace ment? Curve to top or bottom & ..

[@avion195]

Thank you for posting. You make it look easy! This video will figure into my next classic MB purchase decision!

[@timxiao6463]

the video did not record how to rivet timing chain that will required a special tool from mercedes to do so.

[@mercedesclassicswithpierre1753]

these timing chains clip together. the tool you are thinking of is for the diesel engines Tim.

[@georgecurtis6463]

I dont see proper cam timing mentioned often. Its critical.

[@krisperkreme6021]

Would be really cool to see this job in detail (unlinking the chains, etc.).

[@Mitutumuch]

Did you even watch the video?

[@julianwilson7039]

Just did my w116 300sd, 899,000 miles, on what I believe was original chain. Was 17 degrees off on timing lmao

[@Ozkartez]

Is this the same process as in the OM61x Engines? Looking to do my w123 300D turbo. I read somewhere replacement of guides on these engines is very difficult.

[@mercedesclassicswithpierre1753]

haha, not really. the pins are the same, especially in the upper guide, but the ones in the block are more complex. i would only do this on a 400k plus mile engine...otherwise they are usually fine.

[@Ned-007]

How about on W211s? Timing chain replacement after 300k miles?

[@annabella2257]

Hi, Pierre. I desperatly need your help. I´m working on a 450SLC, but I can´t find the timing marks. I wonder if you could help me finding them.

[@mercedesclassicswithpierre1753]

I can..please email me at [e-mail]

[@Dan-HongTong]

Hi Pierre just found your videos and great job mate. Can you please help me, I am removing the head on my Mum's 190d 2.0l,OM601 engine, just want to know do I need to remove the chain tensioner to remove the cylinder head? Need to check and replace head gasket. Many thanks from England. P.S. I drive a 190d 2.5, OM602 engine. All the best Dan

[@mercedesclassicswithpierre1753]

yes, the tensioner, the chain guide and the cam gear. Don't separate the chain. Also, check for cracks on the combustion chamber of the head.

[@Dan-HongTong]

The Pierre Hedary Mercedes-Benz Classic Specialist many thanks for your help, have you known head gaskets to go on these diesels before? It never over heats just oil in coolant reservoir but no gunk under oil filler cap. Thanks Regards Dan

[@gakali123]

Why did the cam starve for oil on this engine? Also, does the master link require a tool to fasten it?

[@mercedesclassicswithpierre1753]

the cam oiler tube kit was worn out.

[@ItsTimePictures]

Great video. Such an important piece of maintenance.

[@carsxarexhard4504]

Hey man I need some help ! I have a 1990 560 sec 5.6 v8 and it’s idle rough 500 or so rpms and it’s shaky . I have moved around the ignition distributor a couple of times and I’m wondering if now I messed something up ?? I need help putting it back where I had it ? I don’t understand the time marks

[@mercedesclassicswithpierre1753]

did you try adjusting the 3mm allen screw in the fuel distributor? this should clean up the idle

[@carsxarexhard4504]

No I haven’t I will try tomorrow. Which way should I be turning lol I’m sorry I really love this car but I haven’t been able to fully enjoy it because of issues it has .

[@carsxarexhard4504]

Can I send you some pics of my car ? Here is my email [e-mail]

[@carsxarexhard4504]

My car has a tag and it says the timing should be 12* before top dead center . I bought a timing light but how do I know what is 12* btdc ? I can find the timing marks below the water pump but I guess I just don’t know what they mean ?

[@mercedesclassicswithpierre1753]

did you remove the distributor?

[@mannexyee737]

Grinding residue goes to where?

[@mercedesclassicswithpierre1753]

on to a magnet! it's there...sorry you did not see it.

[@172-e5s]

Really stupid rookie move to not cover the work area. No magnet will catch all the grindings.

[@e.l.8824]

great video - but never would I let grinding metal- debris going into the open engine......

Excellent video! fully informative!! thanks!! would you recomended do this in a 1973 450sl? or usually they fine for long high mileage? actually car runs fine. thanks!

[@nico-toscani]

Great video, thank you very much.

[@mercedesclassicswithpierre1753]

you're welcome

[@danpicocfp6276]

Brilliant.

[@gakali123]

Great vid! I have a 190e 2.3 with a very subtle chucking type noise from the front of the engine. Are these engines prone to guide failure? 16Ok. Also is a new head gasket recommend based on mileage alone? Thanks. Keep up the good work!

[@mercedesclassicswithpierre1753]

i would not touch the head unless you start to see signs of trouble. I would think the noise is from the belt tensioner or water pump

[@ningishziddashar3480]

I am glad I own a 89 300se.

[@mercedesclassicswithpierre1753]

yes, much easier to maintain than any v8

[@Groveland64]

Been thinking about the timing chain in my 2001 ML320 with 137,000 miles. Is it double row? Should it be changed?

[@michaelroelcandelaria9704]

Pretty good

[@brianmilligan1787]

Using grinder would of left metal granuals

[@LilyoftheValeyrising]

The cam turns at twice the speed of the motor because it’s opening and closing the exhaust and intake ports intermittently. That way we have complete combustion. Cool

[@21divel]

That would be half the speed....small sprocket on the crank vs big sprockets on cams.

[@LilyoftheValeyrising]

Huge lumps of carborundum grinding disk inside the engine! Definitely not a good idea, why not use a chain breaker? Otherwise good video.

[@jasonbirch1182]

Ok seriously. I was joking a year ago and honestly I can handle this job without you, but it's something that you should redo with 35,000 subscribers. This edit is horrific and you don't go into any of the tricky stuff like a making or buying a pin puller and the guide installation, let alone removing the rockers without damaging stuff. I was looking around trying to see what brand guides his kit includes. And no the cam spins half the speed of the motor. You were correct first.
