DETROIT 4 71

Any of you good folk have a picture of the emergency shutoff--in case of a run-a way on a mid 60's Detroit 4 71 diesel engine....thanks

Not difficult to find. Just look for something just upstream of the blower that looks like it will shut off the air.

On the intake housing of the blower, look for a cable like an old lawnmower throttle cable. There should be a lever attached to it, that can be tripped. If tripped, it can be reset by pulling the lever back in place and it'll lock in the open/run position.

Hello lenray,

It is on the intake tube close to the blower. There is a shaft that goes through the pipe that has a flapper on the inside, just like a stove flue damper. There is a spring loaded catch on the outside on the tube. An eyelet has a hole where a cable is attached and it goes into the cab, or control panel, depending on application,

Hello lenray

I found this breakdown for a 6/71. Closer of the same setup as for a 4/71?I was thinking of a different setup on my first reply oops!

Not all have the spring loaded catch. I have one from the late 40's and it only uses a pull cable. However it is in the exact same spot.
