If you are searching for a new injection pump for your Dodge Cummins diesel engine, but are not confident which is the best model, than please continue reading. In this report we clarify 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. However these injection pumps have been know to have their fair share of issues and might need to be replaced.

Bosch VP44 injection pumps execute four fundamental functions:

1. Distributing the high-pressure, metered fuel to 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. Producing the high fuel pressure necessary for injection

The Bosch VP44 is an electronic rotary distributor pump that can differ fuelling and injection timing, and also consists of fuelling, timing, and diagnostic data.

The quantity one trigger 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 about 15psi and if the pressure drops below 5psi an injection pump failure is probable. Bear in mind negative lift pumps can run unnoticed until expensive damage is accomplished to the Bosch VP44 injection pump.

The following are the top two most frequent mechanical failures:

1. Examine Engine Code 216

This is the most common 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 exactly where it wears the housing of the pump down till the fuel is able to bypass the piston. Dodge has recognized this issue for some time, and they no longer even sell the lift pump that goes on the side of the block any longer, instead 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 occurs when the rotor seizes in the distributor section of the pump. The most frequent result in for the seizure is a lack of lubrication. Because 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 quit running, never to commence once more, until the Bosch VP44 injection pump is replaced.

Stopping Bosch VP44 injection pump Failure

The greatest way to stay away from failures of the Bosch VP44 injection pump is to avert them from occurring. Getting a replacement lift pump, one particular that is of a far better high quality than what comes from the factory will aid. 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 problem ahead of you shed the Bosch VP44 injection pump.

Stopping issues before they take place is the finest way to take care of your truck. water ionizer division url
