Interesting Failure Today

Quick thinking. I never thought of how to stop a diesel if the key/stop solenoid failed. Good to know, hope I never have to remember!! I've got a diesel pickup, tractor and RTV 1140.

Now, regarding a diesel you can't shut off as it relates to the classic hydro vs manual transmission debate ( on tractors):
Can most of the hydro tractors stall themselves out if in high range and you stomp the pedal?
I'm pretty sure I could stall my manual tractor if in high gear and I drop the clutch.

Reminds of a time when I was young and worked in a yard that piggy backed semi tractors to transport across the country. I drove one up to the staging area and it wouldn't shut off. I seen a button that said "emergency shut off" so I hit it and sure enough the engine stopped. Boy did I catch h#ll for that. The older guy I worked with told me to never do that again and if the engine doesn't stop just put it in the highest gear and drop the clutch. I won't forget that bit of advise soon.

He said that the fuel shutoff solenoid was iced up, that will keep it from moving enough to shut the fuel off.

Thanks. I missed or just overlooked that point.

Yes, with my HST tractor, it can be stalled by putting too much load on it for the gear range chosen. If for some reason it would not stop when key turned off, I would reduce RPMs to idle, put in high gear, drop FEL and box blade to ground, stomp on HST pedal. I can't imagine a situation where it would not turn off. Cut off solenoid is enclosed and not subject to freezing up.


With an RTV...I DUNNO how you would quickly put a load on it...chaining it to a post in high gear and trying to move it would likely do it...haven't tried...but not an instant fix.

Usually it's easy enough to stuff something over the air breather / snorkel if you can get to it. My luck I wouldn't have anything around to stuff in, so I'd probably have to peel off a shirt.

Well I'm back from town with the new belt, stupid thing was 20 some dollars.

Let's see if the pics will work today.

Thanks guys, I must admit I owe my knowledge of suffocating a engine to YouTube videos of run away diesels, including the one posted previously.

I dunno, that new belt doesn't look it is going to work ... :laughing:

On my tractor with a key solenoid shut off I notices a lever safety wired shut on the side of my injector pump.
Curious guy I am, I cut that wire free and actuated the lever with engine running. Instant shut off!
So I attached a nice thin flexible line to that lever and routed it to the cab with a small red knob attached.

Home brew emergency shut off!
