If you are hunting for a new injection pump for your Dodge Cummins diesel engine, but are not positive which is the greatest model, than please continue studying. In this report we clarify some common failures with injection pumps. The Cummins diesel engine manufactured by Dodge in between 1998 and 2002 came equipped with a Bosch VP44 injection pump. Sadly these injection pumps have been know to have their fair share of concerns and may need to be replaced.

Bosch VP44 injection pumps execute four standard functions:

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

2. Metering the exact amount of fuel for every single injection cycle

3. Varying the timing relative to engine speed.

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

The ionizer oasis online quantity 1 cause of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is usually due to a malfunctioning lift pump. Normal fuel pressure is around 15psi and if the pressure drops beneath 5psi an injection pump failure is probable. Remember negative lift pumps can run unnoticed till pricey damage 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 typical mechanical failure and occurs 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 able to bypass the piston. Dodge has recognized this dilemma for some time, and they no longer even sell the lift pump that goes on the side of the block any longer, instead they replace it with a unit that is now mounted in the tank.

2. 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. Since the fuel lubricates the Bosch VP44 injection pumps, weak lifts pumps can yet again be blamed for this failure. The seizure will then break the Drive Plate and the truck will stop running, in no way to start once again, till the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The best way to stay away from failures of the Bosch VP44 injection pump is to avert them from occurring. Acquiring a replacement lift pump, a water ionizers information single that is of a better good quality than what site comes from the factory will support. If that choice is as well expensive, you can also install a gauge to monitor your fuel pressure. With the gauge you will be capable to know when your lift pump is going out and can easily repair the dilemma just before you lose the Bosch VP44 injection pump.

Stopping troubles prior to they take place is the very best way to take care of your truck.
