If you are hunting for a new injection pump for your Dodge Cummins diesel engine, but are not sure which is the very best model, than please continue reading. In this post we explain some widespread failures with injection pumps. The Cummins jupiter water 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 problems and may possibly need to have to be replaced.

Bosch VP44 injection pumps carry out four basic functions:

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

2. Metering the life ionizer 9100 review exact amount of fuel for every single injection cycle

three. Varying the timing relative to engine speed.

four. Producing the high fuel pressure buy water ionizer comparison needed for injection

The Bosch VP44 is an electronic rotary distributor pump that can differ fuelling and injection timing, and also contains fuelling, timing, and diagnostic data.

The quantity one cause of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is generally due to a malfunctioning lift pump. Standard fuel pressure is around 15psi and if the pressure drops beneath 5psi an injection pump failure is probable. Keep in mind bad lift pumps can run unnoticed until expensive harm is done to the Bosch VP44 injection pump.

The following are the top 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 where it wears the housing of the pump down till the fuel is able to bypass the piston. Dodge has recognized this issue 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.

two. 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 widespread result in for the seizure is a lack of lubrication. Considering that 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 cease operating, by no means to commence once again, until the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The best way to steer clear of failures of the Bosch VP44 injection pump is to stop them from taking place. Purchasing a replacement lift pump, one particular that is of a greater top quality than what comes from the factory will aid. If that choice is also pricey, 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 simply fix the dilemma prior to you shed the Bosch VP44 injection pump.

Preventing issues before they take place is the best way to take care of your truck.
