If you are searching 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 common failures with injection pumps. The Cummins diesel engine manufactured by Dodge between 1998 and 2002 came equipped with a Bosch VP44 injection pump. Regrettably these injection pumps have been know to have their fair share of issues and could want to be replaced. Bosch VP44 injection pumps carry out four standard functions: alkaline water 1. Distributing the high-pressure, metered fuel to each and every cylinder at the precise time two. Metering the precise quantity of fuel for every single injection cycle 3. Varying the timing relative to engine speed. 4. Making the high fuel pressure expected for injection The Bosch VP44 is an electronic rotary distributor pump that can differ fuelling and injection timing, and also includes fuelling, timing, and diagnostic data. The number a single trigger of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is generally due to a malfunctioning lift pump. Normal fuel pressure is around 15psi and if the pressure drops beneath 5psi an injection pump failure is probable. Remember poor lift pumps can run unnoticed till costly harm is carried out to the Bosch VP44 injection pump. The following are the leading two most typical mechanical failures: 1. Examine Engine Code 216 best ionizer oasis This is the most widespread mechanical failure and occurs 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 where it wears the housing of the pump down till the fuel is in a position to bypass the piston. Dodge has recognized this dilemma for some time, and they no longer even sell the lift pump that goes on the side of the block anymore, instead they replace it with a unit that is now mounted in the tank. two. Rotor Seizure life ionizer 9100 An additional mechanical failure with the Bosch VP44 injection pump takes place when the rotor seizes in the distributor section of the pump. The most common 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 quit operating, never ever to begin once more, until the Bosch VP44 injection pump is replaced. 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, 1 that is of a much better good quality than what comes from the factory will aid. If that solution is too costly, you can also install a gauge to monitor your fuel pressure. With the gauge you will be capable to know when your lift pump is going out and can simply fix the difficulty prior to you shed the Bosch VP44 injection pump. Stopping issues just before they happen is the greatest way to take care of your truck.
