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 article we explain some typical 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 issues and may need to have to be replaced.

Bosch VP44 injection pumps execute 4 fundamental functions:

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

two. Metering the exact amount of fuel for each and every injection cycle

three. 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 vary fuelling and injection timing, and also consists of fuelling, timing, and diagnostic information.

The number a single 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 beneath 5psi an injection pump failure is probable. Remember undesirable lift pumps can run unnoticed until pricey damage is accomplished to the Bosch VP44 injection pump.

The following are the best two most widespread mechanical failures:

1. Examine 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 where it wears the housing of the pump down until the fuel is capable to bypass the piston. Dodge has recognized this problem 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.

2. Rotor Seizure

Another 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 yet again be blamed for this failure. The seizure will then break the Drive Plate and the truck will cease running, never to commence yet again, until the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The very best way to avoid failures of the Bosch VP44 injection pump is to stop them from taking place. Purchasing a replacement lift pump, 1 that is of a greater high quality than what comes from the factory will help. If that solution is as well costly, you can also set up 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 effortlessly repair the problem just before you shed the Bosch VP44 injection pump.

Preventing issues prior to they happen is the very best way to take care of your truck. read miracle max ionizer oasis water ionizer info
