Cummins NHC 250 Manual Shut off Valve?

[Wreckclues]

Found this unit in "Cummins Diesel Engines Unit Shop Manual...Bulletin No. 3379084"
Labeled "Manual shut-down valve" but whenever I search for one all I can find are the emergency shutdown valves. Looks like a modified solenoid. Does anyone know where I can source one of these?

If your looking for the P/N here is the Cummins number 154087 for the o- ring that goes under the shutoff.

Never seen one. Scan the front and back covers of the manual and post it

1975. Wonder if that was something used on the supercharged NHRS or the 4 cylinder H495 in industrial stuff? I don't think that the HBIS used a PT system, they still had double disc pumps.

Could also be the first shutdown solenoid version, after these it was upgraded to what is currently on PT pumps.

Something new!

I'll snap a pic and send it to an older guy that did pumps for 40 years.

Manual shut off used on some construction equipment. Was an option, not too common. Dozers, graders mostly.

do any of us here see any reason why the "emergency" shut off cannot be used as a manual shutoff with just the addition of a return spring? .. I did that on one of my M818's for a few months while waiting for me to replace a bad solenoid

Don't see why not.

it worked fine for me while it lasted .. I didn't even bother to remove the return spring
