If you are looking for a new injection pump for your Dodge Cummins diesel engine, but are not certain which is the very best model, than please continue reading. In this write-up we explain 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. Sadly these injection pumps have been know to have their fair share of problems and may possibly require to be replaced.

Bosch VP44 injection pumps carry out four simple functions:

1. Distributing the high-pressure, metered fuel to every single 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. Creating the high fuel pressure needed 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 number 1 result in of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is normally due to a malfunctioning lift pump. Normal fuel pressure is about 15psi and if the pressure drops below 5psi an injection pump failure is probable. Keep in mind poor lift pumps can run unnoticed till expensive damage is completed to the Bosch VP44 injection pump.

The following are the top two most typical 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 where it wears the housing of the pump down till the fuel is in a position 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, as an alternative 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 typical lead to for the seizure is a lack of lubrication. Considering that 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 operating, never to start once again, until the Bosch VP44 injection pump is replaced.

Stopping Bosch VP44 injection pump Failure

The very best way to stay away from failures of the Bosch VP44 injection pump is to avoid them from happening. Purchasing a replacement lift pump, one that is of a better good quality than what comes from the factory will support. If that option is also costly, you can also install 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 very easily fix the dilemma prior to you shed the Bosch VP44 injection pump.

Preventing problems ahead of they occur is the best way to take care of your truck. read water ionizer investigation h2go
