OM606 Cylinder Head Tools - PeachParts Mercedes-Benz Forum

Saturnfan · #1 07-04-2018, 07:50 PM

-I recently bought a 1996 E300D. I'm somewhat new to the W210 chassis, and this is my first OM606 engine. The car is hard to start, and compression is leaking passed several of the valves. Once I commit to removing the cylinder head, I want to be sure I have the needed tools to dismantle it!
-I have the special tools for engine work on the OM615, OM616, and OM617 engines. The fuel injectors, prechambers, and the rings that hold them in are completely different. I've seen conflicting information on what tools will work, and what will not. What specifically should I look for, and where?

I just replaced the head on my 1999 e300d it's just the turbo version but all internals are identical. The only couple special tools I needed were a crank lock via starter ring, a special star bit for the head bolts, some etorx sockets, a stubby 8mm allan key socket for the fan clutch bolt, a good valve keeper remover/installer, and a whole lot of Metric sockets from 32mm down to 7 mm I belive. For the pre chambers you will need a different size tool I belive, they sell it here at pelican parts. I used a site called alldatadiy.com and purchased a 1 year subscription for 15 bucks. It just copied everything from the FSM. It worked like a charm for me. Be ready to spend a good amount on replacement parts, and "while you are in there" parts, excluding the head, I easily spent over $700. But it's a heck of alot cheaper than paying someone else to do the job. If you got questions I can help (except for the intake and exhaust manifolds)

..only bit to add would be glow plug reamer, these can be purchased or made from old glow plugs - below is my ..errr attempt lol

Despite it's appearance, the end result wasn't too bad.

Thanks for the responses. I have a pretty extensive tool collection, including the XZN "Triple Squares." I'm more concerned about the pre-combustion chamber tools. Do the ones for OM602 or OM603 work, or are they different? Where would I get these splined sockets and the extractor? I've found conflicting information about what works and what won't.

You don't need an extractor for the glow plugs. You need an air compressor and an impact gun. The prechamber can be taken out using a slide hammer... That's how the manual recommends anyway.

The pre-chambers have a splined collar which comes out using

You then need a heavily weighted sliding hammer with correct thread, not sure about previous version compatibility.

It looks like I'll have to find a few tools specific to this engine family.

602 589 00 33 02
I'll need the socket to screw out the collar that retains the prechamber, and the threaded adapter for a slide hammer to actually extract it. The size and thread pitch is completely different from the tools I've used on the earlier engines.

Did you do a cylinder leak down test to determine this?

The socket is not expensive, here in UK around $20 or less, for sliding hammer, get a shop to adapt an old injector body -

If this is not practical you can use a bolt, thread is fine pitch metric.

I'm sure I'll have to purchase the special socket for the collar. You're right that I could use a spare fuel injector as the threaded portion for the extractor. I remember when I made the extractor for my first OM 615. There was a particular bicycle tool that I cannibalized due to it having the correct threads on it!
