If you are looking for a new injection pump for your Dodge Cummins diesel engine, but are not certain which is the best model, than please continue studying. In this report we clarify some widespread failures with injection pumps. The Cummins diesel engine manufactured by Dodge between 1998 and 2002 came equipped with a Bosch VP44 injection pump. Regrettably these injection pumps have been know to have their fair share of issues and might need to be replaced.

Bosch VP44 injection pumps execute four 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.

four. Making 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 information.

The quantity a single 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 around 15psi and if the pressure drops below 5psi an injection pump failure is probable. Bear in mind bad lift pumps can run unnoticed until costly harm is done to the Bosch VP44 injection pump.

The following are the leading two most typical mechanical failures:

1. Examine Engine Code 216

This is the most widespread 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 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 anymore, as an alternative they replace it with a unit that is now mounted in the tank.

two. 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 frequent trigger for the seizure is a lack of lubrication. Since the fuel lubricates the Bosch VP44 injection pumps, weak lifts pumps can once more be blamed for this failure. The seizure will then break the Drive Plate and the truck will stop running, never to begin yet again, 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 avoid them from taking place. Buying a replacement lift pump, 1 that is of a far better quality than what comes from the factory will help. If that solution is as well expensive, 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 going out and can easily repair the issue before you shed the Bosch VP44 injection pump.

Stopping difficulties ahead of they take place is the best way to take care of your truck. jupiter technos investigation negative orp enagic
