Vacuum and fuel cut
Vacuum and fuel cut
Fuel Cut- does the fuel cut have constant vacuum going to it and cut the vacuum when you turn the key off, or is it the opposite?
Alda Vacuum- Can I just hook all of these lines up to the main vacuum line, or do they need to connect in a certain order?
by the end of today I think this will be all I have left to do, going to finish the cooling and electrcal this afternoon, I would love to take her for a test drive tonight...
if anyone has any insight it would be great.
Here is a link to the swap.

Swapping an OM617 into my Toyota... I did not pay enough attention when I pulled the motor to the Vacuum system.

(04-08-2009, 11:07 AM)winmutt Fuel cut: vac == shutoff.
ALDA: has no vacuum, that is boost from the back of the intake manifold.
therfore the fuel cut needs vacuum for the engine to start? I have a solenoid I can use to turn it off, so I just need to hook it to the vacuum pump?
there are a few vacuum lines on top of the IP... where do they go? Thanks I am kind of lost on this setup.
A is boost to ARV - (WHAT IS THE ARV)
B is boost from manifold - ( Front of manifold)
E is shutoff valve i think (NEEDS FULLTIME VAC TO RUN?)
C is vac vent from cabin (NOT NEEDED?)
D is either from the main vac line or to the trans cant remember.(NOT NEEDED?)

The engine STOPS when vacuum is applied to the fuel shutoff. Are you using a mercedes automatic transmission? C and D can be ignored if your not. The ARV is an emissions device, you most likely want to disable/remove it during the swap, just cap that off or replace it with a standard banjo bolt without the hose nipple.

I got the truck started, it will run for 5 to 10 seconds and then dies, no matter how I have the throttle applied, It will do this over and over again no problem... It is not the fuel cut as I applied vac to it and the truck wont start at all... what am I missing? any ideas?
Figured out the glow plugs...

(04-09-2009, 11:33 AM)winmutt Linkage WOT? Air in fuel?
ended up being the fuel cut, I forgot to plug it... I have it hooked up now to a vacuum switch so I can turn the truck off from a button on the dash.. The truck drives awsome.

04-15-2009, 01:14 PM #13Nice job man! I like your method of marking the tranny bolt holes in the adapter. Also, it looks like the starter is in the correct place for putting a toyota tranny in a benz.. Do they make a 2WD 5spd with the same pattern? How much torque can these little things take?
