help hurry

[kcim]

i have a 933 cat loader...i just got it and started using it. its great...but its not turning off...the engine is still idle even after i turn it off with the key. i dont see any other emergency shut off button or anything. please help. thanks

Only 2 ways to turn off a deisel and thats to turn off the fuel supply OR block the air supply.

If it's an older machine, there's likely a handle like a "choke" handle that you pull to shut the fuel off...........

Hope this helps.

I had that happen once on a tractor. After some investigation it turned out to be a dead battery. The ignition switch would not function with a dead battery.

I am not familiar with the CAT 933 BUT I do know that there should be a fuel shut-off solenoid on the injection pump. When a diesel does not shut down with a key one of 2 things usually happenned:

1. Current to the solenoid is not getting turned off, maybe a wire went bare?

2. Solenoid went bad.

Those are the 2 most common causes. By this time, you have probably figured out how to "kill" the engine, usually a manual lever near the pump.

Call your local diesel injection shop. It should be a no-brainer to them.

I hope this helps.

Most diesels have a manual shutoff of some sort. On tractors or heavy equipment, it may be very basic: cut off the fuel supply line. There ought to be a valve there somewhere if there isn't an emergency button or some such to push.

Only every happened to me once on my Benzes. The vacuum system is used to shut down the fuel supply, open/lock doors, etc. It had a leak, and the car wouldn't shut down. There's a red button of sorts underneath the hood to shut it down manually. On my Benzes, I could just put it in gear and pop the clutch. Wife can't drive anything but stick shift.

On my JD, it'll be the manual shutoff valve just before the fuel filter.

Try pulling up on the foot throttle, this will shut off the pump. It may pull rather hard!
Let us know!

It's been almost 30 years since I last operated a Cat loader (955K I believe) If memory serves me correctly, you raise the hand throttle past a detent (beyond idle position) and that actuates the fuel shut-off. Ignition keys shutting off diesels is a relatively new concept. Most older equipment would have a seperate fuel "kill switch".

My, how time flies.... /forums/images/graemlins/crazy.gif It's been 30 years already? /forums/images/graemlins/confused.gif

Hopefully by now you've got it shut off!

I'm reminded of some childhood mischief. Probably early teen years, some buddies and I snuck into a gravel pit. Just goofing around on sand piles which lead to climbing on equipement. Found a dozer, pretty large. Of course, we're playing with all the levers and such and we find the magic lever to crank the engine. Couldn't stop there, we actually got the thing fired up. How cool, we thought. Fortunately, none of us was brave enough to try to move the thing but shortly after that we realized we had no idea how to shut it off. I distinctly remember walking (OK, running) out of there with the dozer idling in the background. Only more recently has it occured to me that it probably ran out of fuel before they opened back up and they were probably mighty irritated over the weekend visitors as they bled the fuel system.

And now you all know why machines these days all have locking covers on the control panels. It's all because of me and my friends /forums/images/graemlins/smile.gif

In an emergency situation like this you could put the FEL up against an immoveable object (stump or large rock), put it into HIGH range (low torque) and let out the clutch (or push hard on the HST pedal for you hydro guys /forums/images/graemlins/wink.gif) and the motor should stall. I've done this often by accident. /forums/images/graemlins/smirk.gif

 

[Mith]

how about pinching the fuel line if you want to shut it right off

 

[TOMLESCOEQUIP]

Just curl the bucket back till it stops...........have the loader idleing when you do it.......If the hyd pumps are in good shape this should kill the engine.............

Won't this just trip the relief valve? Mine never stalls the engine regardless of how I curl the bucket.

My bet is to pull up on the accel pedal. Lots of our old 60's and 70's cat equipment shuts off that way. A few of them have a fuel shutoff pull line.. and even fewer ( only the new ones ) have the fuel solenoid shutoff.

I'd go for pulling up on the accelerator pedal too. Had to do that on the last one I was in.

I believe after thinking about it that your 933 is a track loader/ What vintage/model is it?

I mentioned pulling the throttle pedal up earlier (thought it was a rubber tired loader at the time), but the older Cat machines usually utilized some type of over center throttle shut off, be it on the pedal hand throttle or a seperate control. Short story, if it is an older machine it probably uses a manual control for shutdown!

Clark

PS Do you have the operator's manual by chance? I always suggest securing the proper literature for anything if possible!

 

[TOMLESCOEQUIP]

I guess it would depend on how the relief is set........it usually won't pop off quick enough at an idle flow to prevent the motor from stalling..............

 

[stuart]

Please tell us now. Have you turned it off yet???

 

[Phils]

Doncha jus' hate it when a one-post wonder begs for quick help, but never posts again on whether or not any of the answers helped?!? (I do)

Probably out of fuel by now.
