If you are looking for a new injection pump for your Dodge Cummins diesel engine, but are not positive which is the finest model, than please continue reading. In this write-up we alkaline water investigation explain some common 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 need to be replaced.

Bosch VP44 injection pumps carry out four simple functions:

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

two. Metering the exact quantity of fuel for every injection cycle

three. Varying the timing relative to engine speed.

4. Creating 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 information.

The number 1 trigger of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is usually 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. Keep in mind negative lift pumps can run unnoticed until costly damage is accomplished to the Bosch VP44 injection pump.

The following are the top two most widespread mechanical failures:

1. Check Engine Code 216

This is the most frequent mechanical failure and happens 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 water ionizer filter 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 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

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 cause 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 stop running, never to start yet again, until the Bosch VP44 injection pump is replaced.

Stopping Bosch VP44 enagic injection pump Failure

The greatest way to keep away from failures of the Bosch VP44 injection pump is to stop them from taking place. Acquiring a replacement lift pump, one that is of a greater quality than what comes from the factory will aid. If that option is too pricey, you can also set up a gauge to monitor your fuel pressure. With the gauge you will be capable to know when your lift pump is going out and can simply repair the dilemma before you lose the Bosch VP44 injection pump.

Preventing difficulties just before they occur is the greatest way to take care of your truck.
