If you are searching for a new injection pump for your Dodge Cummins diesel engine, but are not sure which is the best model, than please quality jupiter water continue reading. In this article we clarify some frequent failures with injection pumps. The Cummins diesel engine manufactured by Dodge among 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 may possibly need to have to be replaced.

Bosch VP44 injection pumps carry out 4 standard functions:

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

two. Metering the account precise amount of fuel for every single injection cycle

3. Varying the timing relative to engine speed.

four. Generating the high fuel pressure necessary 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 quantity 1 lead to of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is normally due to a malfunctioning lift pump. Standard fuel pressure is about 15psi and if the pressure drops below 5psi an injection pump failure is probable. Keep in mind negative lift pumps can run unnoticed till expensive harm is accomplished to the Bosch VP44 injection pump.

The following are the leading two most common mechanical failures:

1. Check 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 until the fuel is in a position to bypass the piston. Dodge has recognized this difficulty for some time, and they no longer even water ionizers 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 occurs when the rotor seizes in the distributor section of the pump. The most typical cause for the seizure is a lack of lubrication. Because the fuel lubricates the Bosch VP44 injection pumps, weak lifts pumps can again be blamed for this failure. The seizure will then break the Drive Plate and the truck will quit running, by no means to start yet again, until the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The very best way to avoid failures of the Bosch VP44 injection pump is to avert them from taking place. Buying a replacement lift pump, a single that is of a much better high quality than what comes from the factory will support. If that choice is also pricey, you can also set up a gauge to monitor your fuel pressure. With the gauge you will be able to know when your lift pump is going out and can simply fix the problem before you shed the Bosch VP44 injection pump.

Stopping problems just before they happen is the best way to take care of your truck.
