My 79 300SD had that type of pump I think? It was different from the
pump on my '83 300D. Jabba was able to get me a rebuild kit at the time,
that was at least 5 years ago though.

I replaced a booster on the TD and that seemed to help a lot with
vacuum. There were still some leaks somewhere that bled down the vac
but while it was running it was OK. It's kinda a PITA job with lots of
contortions to get the nuts off the booster up above the break petal but
other than
absolutely. Busted booster = no shutoff = trans won't shift right.

Ok so this morning I checked vacuum at the pump and it is strong. I checked
vacuum at line where it connects directly to booster and it is strong so looks
like booster is the culprit. This also makes sense considering that there was
brake fluid vanishing from reservoir a month ago, presumably
yeah, that is why I suggested checking vacuum at the booster, and if
none there, test at the vac pump with the big tube off. Vac at pump and
not at booster indicates broken tube. sometimes the crack is hard to find.

If the vac pump had gone bad, you would have shut off, brake booster problem,
and tranny shift problem. I've had this before on a 617. It sounds like you
also may have moved the little linkage pieces on the shut off valve on top of
the IP as well as knocked off the vac line. Those vac lines
If you have no vacuum at the booster, then take off the big line at the
vac pump, and see if you have vac there.

I did some research and it seems that the 80-85 cars utilize a piston type pump
with piston rings and internal check valves instead of a rubber diaphragm and
rebuild kits are no longer readily available for these newer pumps. I did see a
kit or two on eBay but not sure I trust them. The entire
The price just lowered to $500.
Seriously - your shutoff may have gone down. Coincidences DO happen.

The black tube is not connected to anything under the dash, so maybe it's
the atmospheric vent. Green tube will not sustain any vacuum. Found some
printouts from Marshalls time which state that I'll probably have to pull
the dash and replace a vacuum unit of which there are five. I'll
You don't need to pull the dash, necessarily. IIRC you can
access the vacuum valve cluster behind the ACC pushbutton
unit, and you can do some further MityVac diagnosis there.
Then, at least, you'd know more about what's really leaking.

The green tube with a white stripe which comes out of the firewall into the
engine compartment in my '83 300D will not hold vacuum on the Mityvac. I'm
guessing it goes to the climate control units under the dash.
Can the climate control vacuum units be checked without removing the dash?

vacuum switch that shuts off the fuel to the injector pump.
No, I think you can work through the instrument
cluster hole to do this.

Hi Reid, (also my grandson's name)
When a diesel will not shut down there's usually 2 possibilities - the
vacuum line from the ign switch to the rear of the injection pump where it
attaches to the vacuum shutoff actuator and the vacuum shutoff valve
itself., If you have a vacuum leak in
While the vac shutoff actuator is not very expensive ($30) it can be
tricky
to install. It has a arm on it that must engage a lever inside the
injection
pump. If the arm is not properly engaged the engine will run a top
speed
until it destroys itself.
It's actually a very easy test.
