M119 bolt torque list?

[JC220]

Whilst planning on re-assembly of my spare m119 I am wondering is there a list of torque specs available anywhere for the m119 engine bolts?

Aka, a clear 1 stop list. Or must we refer to the WIS sheets for each task in hand?

Eg:

Camshaft bearing cap bolts: 12nm
Camshaft Gear to Camshaft 18nm
Valve Cover bolts: 9nm..............

But for whole engine

 

[gsxr]

I don't know of any 1-stop list. Each spec is separately in each FSM job.

BTW, the cam bearing caps are 10Nm... did you just list 12Nm as a sample?

Dave, firstly I am most disappointed that you dont have such a list on your bedroom ceiling since you are the w124 / m119 god

Secondly - AH Ha! Please read the WIS doc again. They are all riddled with errors. The images mostly do not match the table list in the same documents....

So I am using the listed specs rather than the pictures.

Thirdly, I am compiling a list. Just wanted to make sure I wasnt wasting time

 

[JC220]

Or 10nm for early, and 12nm for late without dowels?

However I am noting issues like this in nearly all WIS docs. Tabled specs don't match the images alot of the time

GOOD QUESTION! I have noticed some inconsistencies as well. I figure anything in the 10-12 range is fine for either with/without dowels. Probably most of us don't have a torque wench calibrated that perfectly anyway.

Now, the most most egregious error I've seen is the ETA bolt spec, which IIRC is 25Nm... for an M6 bolt. Pretty sure this would result in stripping the threads out of the intake manifold. Most M6 specs are ~10Nmn or so. I tighten ETA bolts by hand, to "snug", using new bolts with threadlock pre-applied.

I recently almost tried to torque these bolts to 25NM but it just didn't sound right as small as they are. I went hand-tight too. Plus, I had a thin coat of sealant on both sides of the gasket anyway. Glad I didn't follow the manual on this one.

Note that the gixer will take you off his christmas card list if he finds out RTV has been applied to gaskets - in particular valve cover gaskets

ESPECIALLY valve cover gaskets. I just replaced these on my wife's E420, where a PO/mechanic used some sealant that looks like chocolate syrup, and dries hard & brittle. I took photos, will post a separate thread on that story. It was a nightmare.

For the ETA, a thin coat of Hylomar sticks the gasket to the ETA so it stays in place while squeezing it through the intake opening. And the Hylomar is easy to remove in the future. Think it's mentioned in the FSM docs too.

The original Permatex "form a gasket" comes to mind.

Drew, you mean the dark brown stuff? I was wondering what the product might be!

 

[sheward]

Yes. That #%@!

edit; I should not refer to "form a gasket in a derogatory way as it served well for years before there were better alternatives and still has uses such as holding gaskets in place for assembly using tiny dots of the product. Complete gaskets, not a good idea.

Thank you for your time Joe

Especially nice list for us electronically challenged folks. Thanks!

Thanks Joe,

You would think Mercedes would have compiled a list similar to yours.

 

[Trae]

Hi guys, I just replaced valve cover gaskets on the Renntech. Following Jono's advice, I torqued the valve cover bolts to 10nm instead of 9nm. He thinks that the valve covers have changed their chemistry over the years and require a bit more torque than the book says. I will run it through a few heat cycles and retighten, if needed, later.

Hi guys, I'm in the middle of replacing cam oilers and camshaft advancer's magnets. Could you please let me know what are the correct torque values for those bolts

Most all those specs will be in the FSM... the numbered items above will be somewhere in Group 01 and 05:

Note that bolt #3 (armature) is a single-use stretch bolt that should be replaced. The rest can be cleaned and re-used. Bolts 2 and 4 all need anaerobic sealant when installing to prevent oil leaks.

RESTO PROJECT: M119 / W124 / E500 Engine Top-End Refresh | Member Roadtrips and Project Journals

What with the current "self quarantine" imposed, I thought it a good time to begin a very long-standing project -- the complete refresh and cleaning of the top end of my M119 engine. Note that my E500 has 143K miles on it. There was ZERO issue with running, other than the following small...

Thank you sir. I will definitely look into it
Does anyone have FSM for W126 & W140 ?

 

[gsxr]

The 126 chassis manual may be online at the 126board.com.

There is no online manual that I know of for the 140 chassis, although there may be some collections of PDF's out there. For the 140 and most other newer chassis you need the WIS.

Camshaft bearing cap bolts: 10 NM !!!!

Camshaft bearing cap bolts: 10 NM !!!!

Already covered way back in post #3

You'll need a low range 1/4 drive torque wrench to get good accuracy that low.
