Question What goes in 4 and 5 on 3/2 Valve on 82 with EGR

Here in this diag what goes in 4 and 5 holes:
http://home.comcast.net/~phantoms/vacuum/egr_82_300d.jpg

I am thinking that maybe b (to transmission) should go in one hole and the line to the transmission should go in the other because someone mentioned some minimal transmission controlling is done by that box ?
Also I am wondering if you did send b directly to transmission, does that mean it is always under full vac (follow line from b to 62)? Or does 72 surge damper prevent that? Or is 62 supposed to prevent it. ? What is 62 "Orifice" for anyway?

thanks

Nothing goes in the #4 and #5 holes.

Don't attempt to reinvent the wheel. b goes to the transmission and it is not under full vac. The orifice, #63 limits the volume to the VCV and the VCV regulates the vacuum to the trans by bleeding a certain amount depending upon the rack position.

The #62 orifice simply restricts the volume to the circuit downstream. It's probably used to prevent a massive vacuum loss if a hose is disconnected or it cracks.

I strongly recommend that you eliminate the line that plugs into #1, eliminate the line that plugs into #2 and eliminate the line that plugs into #3. Much nicer underhood environment.

Thanks Brian. Before I rerouted last weekend I had lines going to all 5 holes. Unsurprisingly, Everything connected up and they were just extra sticks of line plugged in it seemed. But I was curious if there was a purpose.

Thumbs up 1992 300SD Engine Vaccume Diagram

Can anybody help to show me a 1992 300SD General Engine Vacuum diagram? I try to find a leak in the vaccum line that causes the engine continue to run after the switch is turned off. Does this kind of leak affect the A/C compressor to be turned on?
Also, I am seeking advices to remove and reinstall the instrument cluster. I also need to know if anyone knows any reputable individual who can recondition the instrument cluster for the 1992 300SD.

Any help is appreciated.

TIA,
Don
It's the vacuum portion of the Ignition Key switch assembly. When the switch is in the run or start position, the cam causes the vacuum to be disconnect from the shut off circuit of the Injection Pump. When the key is switched to off, the cam lets the valve open and connect the vacuum supply to the shut off circuit.

Took some pictures to replace the lost pictures for the glowkit installation page (http://home.comcast.net/~phantoms/vacuum/index.htm) while I had my daughters car in my shop this week.

Vacuum diagram for a 300SD.

I am in need of a vacuum diagram for a 300SD...any suggestions?

THE REASON: I purchased the car 4 years ago which had just been shipped from Guam (lots of rust). The guy who sold it to me told me it was originally from Germany (The cruise control knob is in German; Beschl./ Verzog.). I've always had trouble figuring out which parts to buy, 1984 parts for the body and 1980 parts for the engine.

The VIN# is WDB1231301A160935. The DMV did'nt even believe this was the correct number.

Anyone else out there own or have heard of such a Benz?

Let me know

It would help if you listed the year and model of the vehicle in your signature.

The 300SD was built in three different chassis versions.

Vacuum Line Diagram 1994 SL 500 Central Locking System

My supply pump is a replacement OEM that has four fittings although the car has five lines. Does anybody know how to determine which lines go where on the vacuum pump in the trunk? Right now I cannot get my interior locks to unlock (center console, door panel storage, etc.). One line is blue and the others are yellow with green stripes.

Does anybody have a diagram for this? Thanks.

Great Job

Thank you for posting those diagrams, 1983 300DT, replaced shut-off solenoid and that did not fix it, have a good spare now though. Door locks do not work will plug today and see if that fixes it.

Thank you again, this sight has been a wealth of information.
