If you are hunting for a new injection pump for your Dodge Cummins follow us on twitter diesel engine, but are not certain which is the finest model, than please continue studying. In this report 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. However these injection pumps have been know to have their fair share of concerns and might require to be replaced.

Bosch VP44 injection pumps perform 4 basic functions:

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

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

three. Varying the timing relative to engine speed.

4. 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 data.

The number one particular result in of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is typically 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. Don't forget bad lift pumps can run unnoticed until costly damage is done to the Bosch VP44 injection pump.

The following are the best two most common mechanical failures:

1. Verify 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 exactly where it wears the housing of the pump down till the fuel is in a position 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, rather they replace it with a unit that is now mounted in the tank.

2. Rotor Seizure

Yet another mechanical failure with the Bosch VP44 injection pump takes place when the rotor seizes in the distributor section of the pump. The most common cause for the seizure is a lack of lubrication. Since 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 stop operating, never ever to start off once more, till the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The best way to keep away from failures of the Bosch VP44 injection pump is to avoid them from taking place. Getting a replacement lift pump, a single that is of a better high quality than what comes from the factory will assist. If that alternative is also costly, you can also install a gauge to monitor your fuel pressure. With the gauge you will be in a position to know when your lift pump is water test kits going out and can very easily fix the problem ahead of you lose the Bosch VP44 injection pump.

Preventing problems the internet before they occur is the finest way to take care of your truck.
