If you are hunting for a new injection pump for your Dodge Cummins diesel engine, but are not positive which is the very best model, than please continue reading. In this article we clarify some widespread failures with injection pumps. The Cummins diesel engine manufactured by Dodge amongst 1998 and 2002 came equipped with a Bosch VP44 injection pump. Unfortunately these injection pumps have been know to have their fair share of troubles and may need to have to be replaced.

Bosch VP44 injection pumps perform 4 simple functions:

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

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

3. Varying the timing relative to engine speed.

4. Producing the high fuel pressure required 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 a single trigger of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is generally due to a malfunctioning lift pump. Normal fuel pressure is around 15psi and if the pressure drops below 5psi an injection pump failure is probable. Don't forget undesirable lift pumps can run unnoticed until expensive damage is accomplished to the Bosch VP44 injection pump.

The following are the best two most frequent mechanical failures:

1. Check Engine Code 216

This is the most frequent mechanical failure and happens 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 where it wears the housing of the pump down until the fuel is in a position 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, as an alternative they replace it with a unit that is now mounted in the tank.

two. 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 again be blamed for this failure. The seizure will then break the Drive Plate and the truck will quit running, never to begin once again, until the Bosch VP44 injection pump is replaced.

Preventing 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. Buying a replacement lift pump, a single that is of a much better high quality than what comes from the factory will aid. If that alternative is too pricey, 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 easily repair the problem before you shed the Bosch VP44 injection pump.

Preventing issues ahead of they occur is the very best way to take care of your truck. how to make water alkaline jupiter water information best reverse osmosis water system
