617 turbo Alda/vacume/Electrical connections

(updated since first posting.)

ok.. here is what I have.

I am assuming that the unit that my kill switch and other vacume ports are attached to is the one that is usually on the side wall of the MB 617turboed cars. It is connected to the Alda with a blue Vacume line.

I think Wire "A" that comes from the Over booste sensor on the intake needs to be hooked up also to the red wire that is my Elec. Kill switch, or would this be hooked in with the Ground (black wire) Is it neccisary when related to performance. I suspect it's wise to attach it though.





I see in this pic I should relable wire "A" to say [to intake overbooste sensor] not [... switch]

Thanks in advance. Im slowly begginng to understand all this.

I know for sure about one thing. The Floor accelorator pedal creates very little movement in the accelerator linkage when compared to the hand throttle. About 1/4 or more less movement. than the hand throttle.

Temp and oil gauge

Am I correct in assuming that this is the water temp. sensor. It has one wire that disappears up into the dash area. The sensor is new as is the gauge.



and this unused location is where the oil pressure sending unit goes?

I gotta Oil gauge yeahhhh

OK, I now know my quess at where the oil pressure sending unit on the block is was way off. I found it over by the oil filter. I followed the line to the oil pressure gauge on the dash.

Looked at the guage closer. I assumed it did not work... it was allways on three bars so I thought. Its in a hard position to see behind the steering wheel.

wellll I looked closer and once the engine was warm it moved to 1.5bar..... HEY.... IT WORKS......

The blue line is a pressure line, not vac.

The shutoff is brown with a blue stripe, fed vac from the main vac line to the brake booster by a brown plastic line -- the shutoff is vacuum powered, not electric.

The wires on the valve cover "box" are for something else -- the shutoff is on the rear of the injection pump, left hand side of engine.

Lack of movement of the control rod is bad bushings in the pivots on the firewall. This will greatly reduce performance, as the "throttle" will only travel about half the normal distance.

huh u lost me.. I have no brake booster and no brown line....but I think that is because you did not catch that this is NOT a stock set up, thus stock colors of wires and vacume lines in most ways dont exist. And yes the red wire as indicated for the shut off isssssss for sure the shut off cause I was there when the mechanic added it. The vaccume/Elec. box is sorta mounted into a bracket and bolted in place on the engine. In the picture you can see it has vacume and electric ports. This is what he hooked the shut off too. Before there was no elec. shut off but a manuel one done by pulling a cable to bring the throttle back to the dead end where it cut off the engine.

Im wondering if what he did was put a manuel shut off switch replacing the automatic turbo overbooste switch. This would make since if the automatic overbooste switch works as a kill switch. If that is the case I should wire the over booste to the same wire where he added the manuel switch.

your comments about bushings in throttle linkages also may or may not be relevant. I have no clue what parts are 617 linkage and what parts are homebrew / unimog stuff.

there is another line. I dont know if it is Vac. or pressure to the front of the switch we have been discussing here. You can see the hose clamp and part of the hose infront of the switch. I'll label it and change the picture here so yall can see what Im refering too. I did not look to see where this goes.

TTT for the Weekday net diesel guru's

This is really starting to baffle me cause I saw a pic of the vacume switch on the firwall. (small cannister looking thing) and that is not what Ive got at all. soooooo.....

Any thoughts.. This vacume/electric switch is rectangular. It has been engulfed in bracketry in the photo above.

Wow.... guess I really confused everyone.... no one responding

here is an update.

The blue line (hose) goes from the vacume switch to the IP... my guess now is this goes to the shut off on the back of the IP.

The front of the switch is fed vacume from the 617's vacume pump.

The black hose goes from Alda to banjo on Intake

The unattached red wire "A" goes to overbooste sensor on the intake.

Where to hook "A" to keep the overbooste protection is the main question.

What is actually vacuum... ohhhhhh the spelling.... gotcha.

no biggy.... I think either spelling is getting the concept across and that is all that counts.
