If you are seeking for a new injection pump for your Dodge Cummins diesel engine, but are not confident which is the very best model, than please continue studying. In this post we clarify some typical failures with injection pumps. The Cummins diesel engine manufactured by Dodge among 1998 and 2002 came equipped with a Bosch VP44 injection pump. However these injection pumps have been know to have their fair share of problems and may possibly require to be replaced.<br><br><br><br>Bosch VP44 injection pumps execute four basic functions:<br><br><br><br>1. Distributing the high-pressure, metered fuel to every single cylinder at the precise time<br><br><br><br>two. Metering the exact quantity of fuel for every injection cycle<br><br><br><br>3. Varying the timing relative to engine speed.<br><br><br><br>four. Making the high fuel pressure expected for injection<br><br><br><br>The Bosch VP44 is an electronic rotary distributor pump that can differ fuelling and injection timing, and also includes fuelling, timing, and diagnostic information.<br><br><br><br>The quantity a single trigger of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is normally due to a malfunctioning lift pump. Standard fuel pressure is about 15psi and if the pressure drops beneath 5psi an injection pump failure is probable. Keep in mind poor lift pumps can run unnoticed till expensive damage is accomplished to the Bosch VP44 injection pump.<br><br><br><br>The following are the best two most typical mechanical failures:<br><br><br><br>1. Verify Engine Code 216<br><br><br><br>This is the most typical mechanical failure and happens over a period of time when weak lift pumps, with low fuel pressure rupture the diaphragm in the front of the injection pump. The timing piston will then vibrate to a point exactly where it wears the housing of the pump down until the fuel is in a position to bypass the piston. Dodge has recognized this difficulty for some time, and they no longer even sell the lift pump that goes on the side of the block anymore, as an alternative they replace it with a unit that is now mounted in the tank.<br><br><br><br>two. Rotor Seizure<br><br><br><br>Another mechanical failure with the Bosch VP44 injection pump occurs when the rotor seizes in the [http://www.youtube.com/watch?v=Z8LhAu1rBU8 click for ionways athena] distributor section of the pump. The most frequent cause for the seizure is a lack of lubrication. Because the fuel lubricates the Bosch VP44 injection pumps, weak lifts pumps can yet again be blamed for this failure. The seizure will then break the Drive Plate and the truck will stop running, in no way to commence once again, till [http://www.amazon.com/shops/AYG2PTRHXHGPF/ the water ionizer] the Bosch VP44 injection pump is replaced.<br><br><br><br>Stopping Bosch VP44 injection pump Failure<br><br><br><br>The very best way to avoid failures of the Bosch VP44 injection pump is to avert them from taking place. Acquiring a replacement lift pump, one that is of a far better good quality than what comes from the factory will support. If that solution is also pricey, you can also install a gauge to monitor your fuel pressure. With the gauge you will be in a position to know when your lift pump is going out and can effortlessly repair the problem ahead of you shed the Bosch [http://www.youtube.com/watch?v=sVVJcLlB4Hw alkaline water] VP44 injection pump.<br><br><br><br>Preventing troubles ahead of they happen is the finest way to take care of your truck.
