e350 4matic engine removal
looking for help with removing the motor from 06 e350 4matic
what to watch out for in what order should I remove parts and the front axles which plug to disconnect and especially what not to do( costly noob mistakes) I'm not a noob to mechanical work or even engine rebuilding but I never worked on Mercedes. somehow I forgot to post what I'm doing lol I'm fixing the balance shaft issue. not upgrading an engine I got the front de-parted already. ac compressor is off and all the other accessories off the timing chain cover is off also downpipe and motor mounts are no problem but I just want to make sure theres no crazy sht to remove front axles and separate the transmission from the motor |
Hey Biff, this is not a front yard activity,therefore I would suggest that you go to Startek.com put your VIN in and get the factory documents to do the job correctly---else drive the car to the bay area and look for BW willy who will tell you tha can do the job in an hour!!

Another proof that Plutoe will never admit "I have no clue" ;)
You are taking big project on your hands and I hope you know the deal about marrying computers. I think you will find it easier with MB engine than with older ones, as instead of maze of cables and hoses, you have couple of electric plugs to pull, beside stuff like axles and shafts. Lot of them are snap-in mounted, so takes seconds to disconnect. Motor mounts are very easy as well. Don't expect too many DIY coming here with experience and I am pretty sure not too many dealers replace MB engines on daily basis. So can't find WIS for whole engine removal, but here are pages you will find useful in case you don't want to spend money per Plutoe advise. http://workshop-manuals.com/mercedes...t_description/ |
You have just been spammed---be watchful!!

updated first post

does startek let you save the pages or print them out of you have to only have it on the computer and cant save them?
because 24 hours is 60 bucks is there even a paper service manual for these cars? or a pdf version of shop manual? that workshop-manuals page is not very detailed |
My EPC will not let me copy the pages, but I am using screenshot captor for that.
No paper shop manual, but ebay is selling illegal electronic copies. |

getting down to the torque converter now.
is there a rear engine mount on this? and also is there a simplified torque specs list floating around somewhere for this motor? m272 like the valve cover torque bolts and all the crap on the front of the motor? the info is really scattered allover interwebs for this. I work on Hondas mostly and have more service manuals than I have use for the nice part is that all the info is available everywhere copy pasted over and over lol. |

Worth every penny, in my experience using it with 10+ automobiles. |
short update.
Mercedes is like a hot GF that has a mole on her V*G. its all good but sometimes its like WTF is that who did this sht. why is there a hydraulic line purposely blocking a transmission case bolt? why is hydraulic line attached to the oil pan where theres absolutely no acess to the bolt from anywhere until you lift the motor... but overall I'm pretty happy with the design and well though out everything. even the WTF parts seem to be designed that way for whatever they had in mind. probably to charge people more |
Yeah, wait til you change the oil by removing the bolt. Oil splashes against the side so it ends up running everywhere. Most other cars I've had never had the oil stream hitting the car.
|
Mercedes design their engines for oil extraction about 40 years ago.
You want to talk about difficult access, try Ford Powerstroke. EGR cooler replacement is 2 days job. |
I'm guessing the differential on the pass side has to come out lol
the 4 matic model fun times I looked at it and walked away today after removing the wheels :) save it for tomorrow everything else is out just need to take out the axles and the box on the side |
I hope you are taking lot of pictures?
With complexity of those engines - not too many DIY are attempting such job, so forum knowledge is starving for such pictorial. |
My cellphones kinda kept breaking.but i will snap pics in reverse order i got my new phone fixed finally.
|
well I'm stuck on the gearbox on the side of the motor.
pass side the gearbox that connects to the shaft that goes to the rear of the car. its impossible to remove it seems like. the hydraulic line is between that and the motor. who the f does that.. they really want you to disconnect aht hydraulic line so they can charge customers more anyway.. 4matic is in my way right now. not helping at all. anyone have input on removing that somehow? I took the axles out which was actually easier than Honda. everything else is pretty much ready all around the motor just that damn box on the pass side of the oil pan with inaccessible bolts from any direction and I need it out to unbolt the transmission cooler line from oil pan |
How many miles on the engine - the gear doesn't look too bad. Did you have the codes?
|
110000 miles. guy says codes came up few months ago.
looks like he drove about 3000-6000 miles after codes came up I got lucky the teeth didn't break off yet the timing is off though the code p0016 and p0017 plus incorrect timing and bouncy belt tensioner gave it away. now a really puzzling discovery I made yesterday. why in the hell theres no threads on replacement timing chain cover ( the thermostat or any other holes..that makes no sense |
I can only guess that the holes are latest technology when they use self-taping bolts to speed up the production.
|
oil pump looks good. Lucky
Btw for anyone wanting to see if theoil pump is damaged or not. Remove oil pickup and flash light into the hole where you see oil pump gear. If gear surface is clean no scratches its good. If there are scratches on one sueface it means metal was in it. Now the question is How do i tell if the chain is stretched? There were no metal chunks in the oil only plastic. And only one side timing marks were off like its described in balance shaft service bulletin when timing chain stretches the timing "coins" wouldbe off center on both heads correct? |
replace chain if you are replacing balance shaft. 200$ part and takes seconds to install. Otherwise you'll get 10k on new shaft and have same exact code.... chain stretched. Just my two cents....
timing marks will be off if gear on balance shaft is worn and or like you said, stretched chain... replace both. new pulse wheels cam magnets oil pump i would replace all of the above even IF they look to be okay. |
Its 200 plus another 600.
Im not trying to replace parts without need. Noobs throw parts at the motor. i make sure the part is damaged before replacing. I almost ordered oil pump without need for it Those chains supposed to last for the life of the motorif im not mistaken. |
That worn out sprocket had to leave sign on the chain.
Replace the chain. https://i43.photobucket.com/albums/e...913_183057.jpg |
