well I'm certainly looking for someone to buy both of them

I'll send you a PM.

run a tube from the IP into the cabin and suck to shut it off.

Okay, I just spent a couple of minutes thinking about this, and I think I have it figured out. A simple relay, a little wiring, and a vacuum solenoid will do the trick.

The vacuum solenoid will take the place of the original vacuum switch. The solenoid will be operated by a relay that is triggered only when the ignition switch is in the run and start positions.

As for a source for vacuum solenoids... Well, just about every EGR system uses one, not to mention EVAP systems, but i think those are mostly pulse controlled, which will take more complicated control system. Surely a sort of universal vacuum solenoid exists, because automation systems use the hell out of the things, but that approach might get expensive, and I don't know if any of them can tolerate being energized continuously.

I can try to iron out some more details if you want, or you can just run with this idea on your own.

wow thats a good idea!!!! one that is normally flow through, then closed when powered. i'm going to have to try this on my truck once i install my 617 into it

X2 on the gorilla knob. The PO of my TD did the same thing,
drilling

a hole through the firewall on the driverside. She then mounted
the knob on the trans hump right by the right knee. Cable runs through
the firewall, all the way up to the radiator, in a big loop, coming back
around over the fenderwell on the passenger side, through the
air cleaner(please, somebody take that damn drill away) to the mechanical
shut off.

Now I have to ask you, Does this sound like something you wanna do????

I have my moments.

Cell, a mechanical shut off that could somehow manipulate the shut-off lever has appeal, too. It's hard for me to envision the linkages and how something could be made to work, as I don't own a turbo OM617. Perhaps I could find some pictures on the forum that would help me come up with an idea.

The one problem I have with a mechanical shut-off mechanism is the boogering that it might do to the dash. I'm not familiar with your truck, but does it by any chance have a spot for a mechanical choke cable, or some place on the dash where you might be able to mount a little shove-tug knob like a choke cable? I think everything was auto-choke by the time your truck was built, but I figured it was question worth asking.

Anyone getting a bright idea to take off the vacuum shutoff valve from the IP completely........... There is a little wire hook at the bottom of the diaphram--that hooks to a little lever linkage in the IP and if that tension is not there on that linkage--The runaway diesel, or as Jethro sang " oh Charly's got the handle-and the train cant slow down-you know it Cant Slow Down"

You know, that sounds good in theory. Good thinking! Now, what are the potential problems associated with that approach? I'm not familiar enough with OM617 IP's to say whether this is advisable.

I was saying --Dont even think about it!

Ah. Interference with the shut-off lever? Like I said, I'm not familiar enough with the IP to know what can and can't be done on that front.

Me? I'm sticking with my vacuum solenoid idea.

Alright we got a wiring guru-- maybe we should start a wire twistin hippie thread like--So whats up with my no-happenin inner drivin lights on my euros?? Also, how would I rig a actuator for my euro w123 wipers, I got the complete harness with relay, but the electric fan and washer pump are also in the same---ok , I want the wipers to work whenever the washer pump is working,------- sorry ,forgive me for hijacking the merciolet.---------I'm leaning tward a couple of rubber caps on the shutoff ports and gittin me a gawdang Go rolla knob!

Ok, what originally got me on this Benz kick was these diesel engines are the most common, easily obtained of all-not to mention smoothness or the reputation- compared to a cummins4bt,perkins etc -bulletproof that I have heard of ever since I was a kid in grade school and the doctors wife from around the block who drove us home from school in the seventies in that fancy orange diesel sedan . Now, anyone wit a few screws loose like every one diggin this merciolet project, we all have the same dilemas, a REAL caveman project has a Stickshift, 4X4 labs -HA Ha yadda yada, or euro 5 speed $2500.00 -Someone snag that one that was posted for $1000-1500 in south Cal- plus the right flywheel, usual $800.00 plus shipping from the faraway land-if one can be found-they are said to no longer be avalable new-but I bet Gurka in India knows different I have been studying for a while what someone posted somewhere in this thread--what about a t5, I was thinking what about using the 240d bellhousing and the correct flywheel-or at least the 4 cyl flywheel ---that luke from 4X4 labs is a Do Do thinking he can make a chevy flywheel work--- some think it might be possible.

You can use the mechanical paddle to shut off engine by mounting a ford fast idle solenoid that pushes (80 granada 255v8) on a homemade bracket to push on the shutoff paddle. version 1 wires to a momentary pushbutton under the dash connected to an everhot wire like the radio feed. Version to uses a pulse- on- off relay triggered from the ignition feed. Mcmaster.com pn 6964k3.

panZZer · #**104** 02-05-2009, 04:07 PM

Or any electric door lock selonoid-70s caddillac are the strongest, or any other electric selenoid-69 camaro cowl hood flapper selenoid etc

IT LIVES!!!

It just ran for the first time in its new body.

http://www.youtube.com/watch?v=tKPI-sqWa6U

chronolog:
1:33 - sputters, but doesn't start
3:20 - finally starts

I used a hair dryer to try and help with the start, as I didn't have the glow plugs hooked up. I think the hair dryer helped, as what you don't see in the video is the first battery which I drained without using a hairdryer...

(hopefully no-one will flame me for starting without an air filter -- i wound up leaving the U-shaped tube at my parent's place. D'oh!)
