If you are seeking for a new injection pump for your Dodge Cummins diesel engine, but are not sure which is the finest model, than please continue reading. In this write-up we clarify some typical failures with injection pumps. The Cummins diesel engine manufactured by Dodge among 1998 and 2002 came equipped with a Bosch VP44 injection pump. However these injection pumps have been know to have their fair share of issues and might require to be replaced.

Bosch VP44 injection pumps carry out four basic functions:

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

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

3. Varying the timing relative to engine speed.

four. Producing the high fuel pressure needed 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 lead to of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is generally 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. Bear in mind bad lift pumps can run unnoticed until costly damage is completed to the Bosch VP44 injection pump.

The following are the prime two most common mechanical failures:

1. Verify Engine Code 216

This is the most common 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 exactly where it wears the housing of the pump down until the fuel is capable 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, instead they replace it with a unit that is now mounted in the tank.

2. Rotor Seizure

Another mechanical failure with the Bosch VP44 injection pump happens when the rotor seizes in the distributor section of the pump. The most widespread cause 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 cease running, by no means to start off again, till the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The finest way to stay away from failures of the Bosch VP44 injection pump is to avoid them from occurring. Purchasing a replacement lift pump, 1 that is of a far better good quality than what comes from the factory will aid. If that solution is too 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 simply repair the issue before you shed the Bosch VP44 injection pump.

Preventing troubles prior to they happen is the finest way to take care of your truck.
