Keep in mind that in "theory" a diesel engine that is not governed can continue to accelerate until it eventually disintegrates. Therefore you can not "just" remove or turn off the governor on any diesel engine.
However if you simply want to increase the top end speed of a vehicle "a bit", you will generally find the governor attached to your fuel pump. Diesel governors are normally a screw in or out adjustment type of thing much like an idle screw on a car but much larger. These screws are locked in place by a tamper proof piece of copper wire that is sealed with a lead seal. Without breaking this seal you can not make any adjustments and if you do remove the seal you will find that you may very well be breaking the law, so I wouldn't tamper if you live anyplace that vehicle inspections are carried out.
P.S. The tamper proof seal makes the governor adjusting screw very easy to spot
This can be easily done by computer by a mechanic tapping into the trucks computer system and resetting the governed speed. Most shops have these computers, but wont touch it as they are tracked as to where when and who changed it in the system.
you can not turn off the governor you can have a new computer chip installed in the ecm and the truck will go alittle faster
Stop the truck, shift into reverse, let off the clutch. Or, if you have an automatic, you just push the button for reverse, then take your foot off the brake. As for maneuvering a trailer, turn the wheel to the left to turn the trailer right and vice versa. If you get a diecast model of a semi truck and trailer and maneuver the trailer while you back it up, it could give you a basic understanding of how it works.
It alows your truck to top out at a higher speed then it would with it on.
Probably a bad ignition switch.
You can only do this in park ... Turn off your truck ,apply the parking brake and turn your truck back on .
Buy new truck with new loan.
A semi conductor component is used to turn off and on the current.
There really is only one way to turn off the air horn in a truck. You need to disconnect the horn.
a dead battery
You either turn it on or off. Whenever you have children in the truck with you, turn the switch to the off position.
A wet kit on a semi truck means it has a power take off commonly called a PTO, which activates a hydraulic pump making it capable of running accessories like a boom or crane if it is mounted on the truck.
Like I told the guy who wanted to know this about Sterling trucks, tampering with the governor on a fleet truck will get you fired. OTOH, if you bought the truck and it's still got the governor on it, just take it to the Volvo dealer and have them turn the speed up all the way. I wouldn't remove the governor; the next buyer might want it. But if you turn it up to about 85mph, it will do the same thing as taking it off.
