If you are hunting for a new injection pump for your Dodge Cummins diesel engine, but are not positive which is the best model, than please continue reading. In this report we clarify some widespread 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 troubles and may want to be replaced.

Bosch VP44 injection pumps execute 4 fundamental functions:

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

2. Metering the precise quantity of fuel for every injection cycle

three. Varying the timing relative to engine speed.

4. Making 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 contains fuelling, timing, and diagnostic information.

The quantity 1 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 beneath 5psi an injection pump failure is probable. Remember bad lift pumps can run unnoticed till costly harm is done to the Bosch VP44 injection pump.

The following are the top two most typical mechanical failures:

1. Examine Engine Code 216

This is the most widespread mechanical failure and occurs 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 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, instead they alkaline water replace it with a unit that is now mounted in the tank.

2. Rotor Seizure

Another mechanical failure with the Bosch VP44 injection pump happens when the rotor seizes in the distributor section of the pump. The most widespread lead to for the seizure is a lack of lubrication. Considering that the fuel lubricates the Bosch VP44 injection pumps, weak lifts pumps can once again be blamed for this failure. The seizure will then break the Drive Plate and the truck will cease running, by no means to commence once more, till the Bosch VP44 injection pump is replaced.

Stopping Bosch VP44 injection pump Failure

The finest way to steer clear of failures of the Bosch VP44 injection pump is to avert them from taking place. Buying a replacement lift pump, 1 that is of a greater good quality than what comes from the factory will support. If that alternative is also pricey, 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 ahead of you shed the Bosch VP44 injection pump.

Preventing troubles just before they cheap athena water happen visit alkaline water is the finest way to take care of your truck.
