If you are searching for a new injection pump for your Dodge Cummins diesel engine, but are not sure which is the greatest model, than please continue studying. In this article we explain some frequent failures with injection pumps. The Cummins diesel engine manufactured by Dodge among 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 perform four fundamental functions:

1. Distributing the high-pressure, metered fuel to each and every cylinder at the precise time

two. Metering the precise amount of fuel for every single injection cycle

3. Varying the timing relative to engine speed.

four. Making 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 contains fuelling, timing, and diagnostic data.

The quantity one trigger 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 around 15psi and if the pressure drops below 5psi an injection pump failure is probable. Don't forget poor lift pumps can run unnoticed until costly damage is carried out to the Bosch VP44 injection pump.

The following are the prime two most typical mechanical failures:

1. Verify Engine Code 216

This is the most widespread 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 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.

two. Rotor Seizure

Yet another mechanical failure with the Bosch VP44 injection pump happens when the rotor seizes in the distributor section of the pump. The most frequent trigger for the seizure is a lack of lubrication. Considering that the fuel lubricates the Bosch VP44 injection pumps, weak lifts pumps can once more be blamed for this failure. The seizure will then break the Drive Plate and the truck will cease running, never ever to begin once more, until the Bosch VP44 injection pump is replaced.

Stopping Bosch VP44 injection pump Failure

The best way to keep away from failures of the Bosch VP44 injection pump is to avoid them from happening. Acquiring a replacement lift pump, 1 that is of a far better quality than what comes from the factory will support. If that solution is too expensive, 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 difficulty prior to you shed the Bosch VP44 injection pump.

Preventing troubles ahead of they occur is the best way to take care of your truck. h2go melody water ionizer ionways delphi
