Pic Request: OM606 NA
 

If anyone here owns a 95 E300D could you please take some pictures of the throttle cable linkage that mounts to the head for me. (I know I know its a diesel, no throttle etc etc)

I need reference shots for my 606 swap and I want to piece together the parts I need so I can order the bare minimum from the dealership.

Pics from above, close up, shots if you can of where it meets the injection pump.. etc. I've attached what EPC shows so I just need to see it in place as the center of attention. I've been pouring over tons of videos and photos of 606's just hoping for some reference shots of this piece but no one really pays much attention to it.

I'd rather spend the $100-150 on this linkage than cobble together a mess of linkages from the junk yard since this is one of the main pieces to get the 606 to work in the earlier w124.

much appreciated.

Darn it, just sat down. I just put everything back together after replacing all the fuel lines to the IP. Sorry, it's been a long day of wrenching... and I'm not pulling it all apart again.

What do you want a picture of specifically? I'll be back in there later this week. Are you looking for screw points? Where the linkage sits in the manifold?

Yes, bolt points, where the linkage sits, and high res shots of the linkage set up. Once I get my pump in I will be able to determine what else I need.

The plate by number 74 is not able to be selected in EPC so I wonder if its on the IP or not available. #74 is a bolt apparently.

Pictures
 

Here's a picture I took when I was deleting the throttle flap. I don't have any detailed pictures at the moment.

Ran out and took these for you. Note this car is for off road use and does not have the flap on the intake in operation thus the linkage is missing.

I don't even run a fan shroud. Note too the air filter I'm running. All that stuff got taken out when the wife rear ended a Bronco.

This car just turned over 300k miles:).

So the spring with the x is not needed, sweet less stuff to buy.

I'm curious about the linkage that connects to the injection pump. I have a handful of links from. 617 won't know if I have correct length links until I have the throttle assembly ordered and mounted. I'll have to cut the web out between the intake runners.

The case of the missing links
 

I had often whined about the heavy accelerator pedal feel; while deleting the flap, I ran into [on line] a gentleman who suggested removing the spring. The result is a much lighter feel but the mechanism tends to hang up and not return to idle due to dirt/friction in the linkage. I replaced with all-metal links the existing plastic-ended links that connect the linkage down and back to the IP and the cruise control actuator. The all-metal links, properly lubricated (I used anti-seize) eliminated the friction problem.

You wold t happen to still have the plastic links would you?

I've got a few miscellanous links if they would help you.

I probably have the originals put away somewhere. If you like, I could build you a set of all-metal links like the one in the picture.

Jeremy

You'd have a second customer here for those.

I just need the measurments, I'm fully capable of making my own most likely. I have a ton of linkages to pick and choose from and tap and die sets..

The N/A Inlet-manifold is different, so you'll possibly need to make a few holes between the runners and add a few mounts for the linkage.....

This I know and had mentioned. I just have to cut out a short section between the runner for IIRC cyl 2 and 3

Here ya go.

It was misting and 37°F when I took the pics, which is why everything is wet. These are from my phone, my camera wasn't cooperating. If you need more resolution, let me know as the car still isn't fixed and I'll need the intake manifold off again tomorrow.

Thanks!
I probably won't have cruise control for my car so hopefully I can eliminate all of that

#5 on the diagram is officially NLA by Mercedes... crap

I need someone with a 606 NA locally to let me take the linkage apart and make drawings of the part and just make the stupid thing

I don't see a numbered diagram but ALL you need is what the arrows point to in this picture. The linkage support fastens to the cam cover under the plastic cover. Couple 10mm hold it on. You should be able to still purchase the bracket and can make up the piece going to the injection pump linkage. You will need the plastic piece that helps hold the throttle linkage in place.

the part that mounts to the intake manifold is what is NLA

Links
 

Here is a photo of the two links. The long one connects from the accelerator cable, through the NLA part attached to the intake manifold, down to the IP. The short one connects from the IP to the cruise control actuator.

http://i323.photobucket.com/albums/n...ps95f7b14d.jpg

The long one has cable ties on one end because of my mistake. I thought the plastic ends unscrewed from the metal rod but they do not. (Metal ends do unscrew.) The plastic is molded to fit the metal rod; if you twist, the plastic simply breaks.

The important dimension is the center-to-center length as shown. The overall length depends on the material and the subcontractor. The center dimensions are critical so that the rod will match the ball-ends that the links joins. I made my measurements using a digital vernier caliper; the only error comes from my judgement of the center of the sockets and should be less than 1/2 mm.

The linkage that attaches to the intake manifold is regretfully not a trivial piece of metal. Your best opportunity would be to buy an original from a junkyard or to make a copy of an original borrowed from someone who has their car torn apart.

I'll be in Orlando for work on Friday and can bring the bracket with me if you want to meet up at lunch time.

I should have PM'd you. I do come to Orlando a couple times week and it looks like I'm no closer to figuring out what is wrong with my car so if you still want to take a look at the bracket let me know and I'll bring it along with me next week.

Hi folks,

I came across this thread whilst in the final throws of reassembling my OM606.910 after rebuild.

As with these 'hobbies' they always take a lot longer than you first anticipate by which time a few more grey cells have evaporated hence my current dilemma - 'now where did that bit go' :)

Jeremy's pic above is a great help for the reassembly of the throttle linkage where I couldn't see an exact bolting point.

The remaining questions I have are detailed in the following pics, firstly what bolts into the hole circled in green?

http://i225.photobucket.com/albums/d...ps0be3a667.jpg

I'll start a second post with a few more assemble pics, thanks

Also could someone confirm the V shaped vacuum connectors circled in green is universal, i.e can connect either way around to the unit attached to the manifold.

Please also confirm butterfly resonance valve pipe is correct too, much appreciated.

Hole
 

My '95 and '96 E300s both have that tapped hole and it is not used at all (so you're not missing anything).

Plumbing
 

The vacuum source hoses can be connected either way. The challenge with the connection to the resonance flaps is that the electrical plugs can go on either way so it's possible to get them backwards. I need to do some research -- maybe someone else will post the secret in the meantime.

EDIT -- here's the answer:

The dual "switchover valve" that bolts to the underside of the intake manifold has two identical valves. Each can operate either the flap in the crossover pipe or the flap in the intake manifold. It's possible to get them backwards as the electrical plugs are the same. The wire colors, however, are unique, allowing you to tell which is which.

The valve that controls the flap in the crossover pipe has a yellow wire. The valve that controls the flap in the intake manifold has a gray wire (shown in your picture along with the green circle around the Y-connection). Both valves have a brown (ground) wire. It doesn't matter which of the two valves controls which flap as long as the wire colors go to the valve for the matching flap.

The recently-posted Russian web site with the Mitchell electrical diagrams shows the flaps in the engine wiring file "3.0L Diesel, Engine Performance Circuits," which is "5378.pdf" if you save the file to your hard drive. I need to check both of my cars to make sure they're wired right and maybe put color-coded tags on the cables and hoses so I don't get them confused in the future.

Thank you so much Jeremy for your help

The missing bolt answer made me smile as I took ages pondering whether or not to post up a question not wanting to look daft.

This is great, thank again for taking the trouble to source the info.

I hope this post is still within the spirit of the original post regarding pictures.

Engine started after a little tinkering and settled down to a smooth idle. All good on that front.

Although the manifold is bolted on to allow use of the throttle it's only nipped up by a few bolts to allow easy removal. The reason being two fold, firstly I am unsure as to exact bolt holes for the bracket below, I know it bolts on using the manifold bolts over the top but other than that it's a bit of a mystery.

Secondly is the fitment of a new oil breather set. Whilst I have the MB instructions it doesn't appear to show where the part fitted to the head.

If anyone has a pic with the cover off that would be cool, thanks

Where does the part in green fit in?

Here's a shot of my NA606 when it was apart for new glow plugs, may be some help...

Thanks, that's ideal and sorts out the oil breather plumbing. I'll have another look through the WIS diagrams to see if I can spot anything related to the bracket.

Spot on, thanks

Back again folks wth couple of queries.

I would have started a new thread but not sure of part name, it's under the green circle and controls the injector pump at various altitudes.

http://i225.photobucket.com/albums/d...ps0b7f897f.jpg

During the last strip down I had intended to test it but overlooked it during reassembly. Basically it's been bent out if the way to allow access to the glow plugs and now sports a large lean to one side.

The metal is heavy gauge steel and very hard to bend back without other damage. During a vacuum test the small spigot in the centre temporarily moves but no vacuum is held.

Are they supposed to hold a vacuum on the pipe connected?

http://i225.photobucket.com/albums/d...ps55c3cc9a.jpg


Thanks,

Another quick question, is there meant to be a vacuum pipe attached to the bottom (where vac test pipe is connected)?

I can't see a spare pipe in the engine bay?

I remember reading about that altitude device in the SL forum here. If you find out anything, please post back to this thread.

it's called an altitude compensator

Thanks for the reply.

I should have a snapshot from WIS later in the week hopefully providing a bit more detail.

A quick search for 'altitude compensator' brought up the thread you were referring to http://www.peachparts.com/shopforum/tech-help/314060-bosch-altitude-compensator.html
