If you are seeking for a new injection pump for your Dodge Cummins diesel engine, but are not certain which is the finest model, than please continue studying. In this post we explain some common failures with injection pumps. The Cummins diesel engine manufactured by Dodge between 1998 and 2002 came equipped with a Bosch VP44 injection pump. Unfortunately these injection pumps have been know to have their fair share of problems and could want to be replaced.

Bosch VP44 injection pumps perform 4 fundamental functions:

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

2. Metering the precise amount of fuel for each 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 includes fuelling, timing, and diagnostic information.

The number a single result in 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 about 15psi and if the pressure drops beneath 5psi an injection pump failure is probable. Remember negative lift pumps can run unnoticed till expensive harm is completed to the Bosch VP44 injection pump.

The following are the leading two most common 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 where it wears the housing of the pump down till the fuel is in a position 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, as an alternative they replace it with a unit that is now mounted in the tank.

two. Rotor Seizure

One more mechanical failure with the Bosch VP44 injection pump happens when the rotor seizes in the distributor section of the pump. The most typical trigger 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 quit operating, never ever to begin once more, 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 stop them from occurring. Getting a replacement lift pump, 1 that is of a much better high quality than what comes from the factory will support. 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 in a position to know when your lift pump is going out and can effortlessly repair the difficulty ahead of you shed the Bosch VP44 injection pump.

Preventing difficulties before they happen is the greatest way to take care of your truck. jupiter melody jp104 water ionizer analysis guide to miracle max
