If you are seeking for a new injection pump for your Dodge Cummins diesel engine, but are not positive which is the very best model, than please continue reading. In this report we clarify 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. Regrettably these injection pumps have been know to have their fair share of issues and may possibly require to be replaced. Bosch VP44 injection pumps execute 4 standard functions: 1. Distributing the high-pressure, metered fuel to every single cylinder at the precise time 2. Metering the exact amount of fuel for every single injection cycle three. Varying the timing relative to engine speed. four. Generating 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 contains fuelling, timing, and diagnostic information. water ionizer The number one particular lead to of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is normally due to a malfunctioning lift pump. Typical fuel pressure is around 15psi and if the pressure drops below 5psi an injection pump failure is probable. Remember bad lift pumps can run unnoticed until pricey damage is accomplished to the Bosch VP44 injection pump. The following are the leading two most widespread mechanical failures: 1. Verify Engine Code 216 This is the most common 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 where it wears the housing of the pump down till the fuel is able 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 any longer, as an alternative they replace it with a unit that is now mounted in the tank. ionways athena two. Rotor Seizure One more mechanical failure with the Bosch VP44 injection pump happens when the rotor seizes in the distributor section of the pump. The most typical result in for the seizure is a lack of lubrication. Considering that 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 operating, in no way to begin yet again, till the Bosch VP44 injection pump is replaced. Preventing Bosch VP44 injection pump Failure The greatest way to stay away from failures of the Bosch VP44 injection pump is to avert them from taking place. Getting a replacement lift pump, one that is of a better quality than what comes from the factory will support. If that option is as well costly, you can also set up 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 effortlessly fix the problem before you shed the Bosch VP44 injection pump. Stopping issues prior to they occur is the finest way to take care of your truck.
