If you are seeking for a new injection pump for your Dodge Cummins diesel engine, but are not certain which is the finest model, than please continue studying. In this post we clarify some frequent failures with injection pumps. The Cummins diesel engine manufactured by Dodge between 1998 and 2002 came equipped with a Bosch VP44 injection pump. Sadly these injection pumps have been know to have their fair share of problems and might require 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

3. Varying the timing relative to engine speed.

four. Producing 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 information.

The number one result in of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is usually due to a malfunctioning lift pump. Normal fuel pressure is about 15psi and if the pressure drops beneath 5psi an injection pump failure is water ionizer website probable. Bear in mind negative lift pumps can run unnoticed until expensive damage is carried out to the Bosch VP44 injection pump.

The following are the leading two most widespread mechanical failures:

1. Check 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 intangible 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 capable 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 any longer, rather they replace it with a unit that is now mounted in the tank.

2. Rotor Seizure

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 widespread cause for the seizure is a lack of lubrication. Because alkaline diet critique 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, by no means to start off once again, until the Bosch VP44 injection pump is replaced.

Stopping Bosch VP44 injection pump Failure

The finest way to keep away from failures of the Bosch VP44 injection pump is to avert them from happening. Acquiring a replacement lift pump, one that is of a better good quality than what comes from the factory will support. If that alternative is as well 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 effortlessly repair the dilemma ahead of you lose the Bosch VP44 injection pump.

Stopping issues before they happen is the best way to take care of your truck.
