If you are hunting for a new injection pump for your Dodge Cummins diesel engine, but are not confident which is the finest model, than please continue studying. In this report we explain some typical failures with injection pumps. The Cummins diesel engine manufactured by Dodge amongst 1998 and 2002 came equipped with a Bosch VP44 injection pump. Unfortunately these injection pumps have been know to have their fair share of concerns and may want to be replaced. Bosch VP44 injection pumps carry out 4 simple functions: 1. Distributing the high-pressure, metered fuel to every cylinder at the precise time two. Metering the precise quantity of fuel for every injection cycle three. Varying the timing relative to engine speed. 4. Creating the high fuel pressure necessary for injection The Bosch VP44 is an electronic rotary distributor pump that can vary fuelling and injection timing, and also includes fuelling, timing, and diagnostic information. The quantity 1 result in of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is usually due to a malfunctioning lift pump. Typical fuel pressure is about 15psi and if the pressure drops beneath 5psi an injection pump failure is probable. Don't forget undesirable lift pumps can run unnoticed until expensive harm is accomplished to the Bosch VP44 injection pump. The following are the leading two most frequent mechanical failures: 1. Examine Engine Code 216 This is the most common mechanical failure and happens more than 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 capable to bypass the piston. Dodge has recognized this problem 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. two. Rotor Seizure Yet another mechanical failure with the Bosch VP44 injection pump takes place when the rotor seizes in the distributor section of the pump. The most frequent trigger for the seizure is a lack of lubrication. Since the fuel lubricates the Bosch VP44 injection pumps, weak lifts pumps can once again be blamed for this failure. The seizure will then break the Drive Plate and the truck will stop running, by no means to commence once more, until the Bosch VP44 injection pump is replaced. water ionizer Preventing Bosch VP44 injection pump Failure The finest way to avoid failures of the Bosch VP44 injection pump is to avert them from occurring. Getting a replacement lift pump, one that is of a greater good quality than what comes from the factory will support. If that choice is too costly, you can also install a gauge to monitor your fuel pressure. With the gauge you will be able to know when your lift pump is going out and can simply fix the problem just before you lose the Bosch VP44 injection pump. Stopping troubles ahead of they occur is the very best way to take care of your truck.
