Details on Bosch VP 44 Diesel Pumps for Diesel Trucks

If you are looking for a new injection pump for your Dodge Cummins diesel engine, but are not certain which is the greatest model, than please continue reading. In this article we clarify some frequent 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 could need to have to be replaced.

Bosch VP44 injection pumps execute 4 simple functions:

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

2. Metering the precise quantity of fuel for every single injection cycle

3. Varying the timing relative to engine speed.

4. Making the high fuel pressure essential 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 number a single cause of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is typically due to a malfunctioning lift pump. Regular fuel pressure is about 15psi and if the pressure drops beneath 5psi an injection pump failure is probable. Don’t forget negative lift pumps can run unnoticed till pricey damage is done to the Bosch VP44 injection pump.

The following are the best two most typical mechanical failures:

1. Verify Engine Code 216

This is the most common 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 problem 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.

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 common lead to for the seizure is a lack of lubrication. Because 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 ever to begin once more, until the Bosch VP44 injection pump is replaced.

Stopping Bosch VP44 injection pump Failure

The greatest way to avoid failures of the Bosch VP44 injection pump is to stop them from happening. Purchasing a replacement lift pump, 1 that is of a far better high quality than what comes from the factory will help. If that alternative is too 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 going out and can easily repair the problem before you shed the Bosch VP44 injection pump.

Preventing troubles ahead of they take place is the greatest way to take care of your truck.
