Stopping the fuel is how it stops the engine from running.........imagine a engine you can't turn off.....also is part of safety system
yep ......only two ways to shut a diesel off.......cut the fuel .....or cut the air.....if you cant stop the fuel the go to way to stop a diesel engine is to shove a towel or something in the intake to starve it of air ......diesels do not require any form of electrical ignitionthanks.... I was thinking the running system was shut off via the key -ignition system, not fuel delivery system.... it shuts off so fast i wouldnt have thought it was the fuel system!
I would be interested in viewing the video ....so if I ever have a issue I am informed...so if it's convenient you could post it for others thxthanks for the last 2 replies!! this last few days the shut off goes bad every time i turn the tractor off.... 10 minutes or 2 hours... I had to remove the device, pump it by hand to squeeze the oil out and reinstal and bammm, the tractor starts..... I finally figured i shouldnt turn the tractor off until i was done for the day or I wanted to go through the proceedure again.. I ordered a new part...then i am going to disect the old one.. the one in there now IS A REPLACEMENT from about 3 years ago! I found this problem on youtube. two guys posted videos on what they had to do to over come the issue. thats how i found out what to do.. They had mentioned it was a KNOWN problem and lots of tractors in my range. 4100 4200 4300 440 4500 4600 4700. (for JD Driver): since once i pump the oil out of the unit, and reinstall, the tractor starts every time, I figured its not an electrical issue... Im guessing since you more experienced guys didnt know of this issue there is little chance there is a new solution or an improved part!
