You have put the chain backwards, the grease holes go towards the outside and you put them towards the inside.

[@TxRzrBk]

I agree, this chain will stretch very quickly with the oil holes facing down

[@ferenctulics9688]

Wow! I didn't even saw those little holes until you mention them. Thank you!

[@TxRzrBk]

The febi replacement chains have the oil holes like the OEM chain however the INA chains do not have the holes

[@everttaube4089]

It's correct, holes in chain outside for lubricant. Specific in WIS If not 🚫

[@elrazky]

Thank you for this informative video. I wonder what state do live? I need your expertise :)

We are in Bellingham WA. Contact here: www.sprintermotors.com We will be happy to help!

[@ukaszjurys2475]

Should you replace slides ? I have heard that MB slides are not destructable

[@sprintermotors]

You mean guide rails? Depends on mileage and wear. In 90% cases no need to do it.

[@ukaszjurys2475]

[@Agecatcher]

@@sprintermotors mine rattles on cold starts for 2 sec, its driven 272k kms, never replaced, i think the tensioner is bad, but most likely its streched aswell, im a 2nd year apprentice and i want to do this job myself, but any tips?

[@timthatcher6131]

Thanks for the Video, I noticed you didn’t use the tools that hold the camshafts in place so they can rotate. Would you say these aren’t necessary? Thanks

[@garagesociety9907]

Great video

[@NoStiemTravel]

wish me luck! I want to try this on a N47 BMW engine :). Ony advices before desister?

[@sprintermotors]

@@NoStiemTravel also very common failure unfortunately. Get proper tools, and be careful!

[@eveniton]

Thanks for good explanation. Did you draw the new chain with the old chain tensioner in its place?

[@sprintermotors]

@@eveniton yes, and after that, you replace the tensioner with a new one

[@edrieahmadi6907]

Hello, how are you? One question, do you have to remove the chain tensioner with this tool or not?, I mean if the chain is secured by this tool.From your explanation I understood that the chain tensioner needs to be replaced. My question only concerns when you put in the new chain, whether or not you remove the chain tensioner while replacing the chain, thanks

How do you replace a broken camshaft sprocket on 08 Sprinter?

[@abdelazizboutaibi8007]

I have engine messed up in my Mercedes sprinter please give me advice do I need to buy another engine or I can rebuild the original one thank you for your help

[@sprintermotors]

Sure! If any of your main bearings are toasted or any damage present on cylinder walls - your engine will be done. If there are no damage on those spots - it is rebuildable.

[@mrsmith2475]

Did you replace any seals for the injectors? Do you have to bleed the injectors? Thanks great video

[@Agecatcher]

you dont have to bleed the injectors, its common rail, so you can prime the igniton, to get fuel going, and then start after turning the key 10-15 times

[@TxRzrBk]

Why did you remove all of the cam hold downs? In this configuration I would think the cams would be lifted by the opposing force of the valve springs.

[@sprintermotors]

Cam holders are not necessary to do the timing chain.

[@MikeEwart-w5n]

cant you turn the tool around and push the pin out to the rear instead of fighting with the sprocket?

[@sprintermotors]

You can't do it that way.

[@alidogansoy5650]

Bonjour merci pour la vidéo 👏pouvez-vous me dire il faut compter combien de temps pour remplacer la chaîne de distribution sur une e350 cdi de l’année 2010 mois d’août ?cordilement

[@sprintermotors]

Bonjour! Il faut environ 6 à 8 heures pour faire le travail complètement. Sur ML c'est un peu plus facile que sur un Sprinter

[@alidogansoy5650]

@@sprintermotors merci beaucoup 😊 avez vous une idée de prix combien ça peut me coûter à peu près. Cordialement

[@Stmarkko]

How are you able to rotate cam without valve coming into contact with piston? Great video, om642's are best small v6 diesels. 290000 miles and 9' of TDC. 11' is max.

[@sprintermotors]

We did not do anything to the timing itself. We just disconnected old chain, connected new one and rolled it through.

[@mihaisorin9705]

the old chain does not look that bad, can i just change only the tensioner?

[@sprintermotors]

You have to replace chain. Because problem is in the chain not in the tensioner.

[@lionsdejudah]

@@sprintermotors Is there any way to check to see if it’s a stretched timing chain?

[@georgebest2499]

Hello Friend. I have a ml 320 cdi 2007 year. Sometimes in the morning when I start the car for the first time, it makes a noise for exactly 1 second. Something rattles and stops after a second. My car has a mileage of 280,000 km. I don't know if this timing chain has ever been changed or not. I know that the air conditioner compressor bearing or magnets are damaged and this is also making noise. This noise can be heard from the compressor of the air conditioner. I hope the timing chain doesn't need to be replaced.

[@СлаваРацой]

[@lionsdejudah]

2011 GL350 here with 230K miles, and the last couple of days I’ve been hearing a constant light Slap ing sound on top of engine near the front drivers side camshaft.

[@sabinmari17]

Anyone around NY 3 state are that know how to and can do this?

[@TiagoNevesNET]

Not too sure about beating on the cam sprocket with hammers, fairly sure that's NOT in the mercedes shop manual! You can just vice those pins, seems to me you did more harm than good here.

[@sprintermotors]

It just seems to you. Did over 100 chain replacements - no problems whatsoever.

[@caalbert7206]

Bro, the litle holes in chain should be facing out....sorry...

[@karldingbat]

Do not do this!!! I tried to do this but the pin and bolt fell from the tool into the crank case and i had to remove and disassemble my engine to get it out

[@sprintermotors]

No offense, but it's totally your problem. You could've put some napkins and prevent that. Even if it felt down, you can simply remove the oil pan, and no need to disassemble the entire engine.

[@karldingbat]

@@sprintermotors no, cheap Chinese junk not fit for purposes and there's no way to remove the oil pan on a 4x4 sprinter without engine out, again DO NOT USE CHEAP JUNK!!!!

[@sprintermotors]

@@karldingbat I used cheap chinese tool over 200 times - no problems whatsoever. You have to grind it a bit to fit perfectly. You can remove small oil pan on 4x4 Sprinter WITHOUT ANY problems.

[@karldingbat]

@@sprintermotors errrr, no you can't ive got 1 and the small oil pan is obscured by the leaf spring hanger and the subframe supports!!!

[@sprintermotors]

@@karldingbat Please do not argue. You can remove the lower oil pan without ANY issues. Middle pan - you can't remove. But lower - easy.

Mercedes-Benz is such a unreliable garbage car.W 203 was disaster. Ten the first version of w204 was a bit better and then mercedes screwed up with totality bad om651 engine.Injectors and timing chain and tensioners malfunctions. Om 651 have only 1 chain its simplex and previous one was duplex.I though nothing can be so bad as bmw n47 engine but i was so wrong Mercedes-Benz is one of the most unreliable vehicles Also when you changing that tensioners on mercedes you have to take engine out same as on n47 bmw.I will never buy any mercedes again.I will buy only Japanese products ( And yes,i do own W204) at the moment.
