If you are seeking for a new injection pump for your Dodge Cummins diesel engine, but are not certain which is the finest model, than please continue reading. In this article we clarify some widespread failures with injection pumps. The Cummins diesel engine manufactured by Dodge amongst 1998 and 2002 came equipped with a Bosch VP44 injection pump. Unfortunately these injection pumps have been know to have their fair share of concerns and might need to be replaced.

Bosch VP44 high quality alkaline water filter injection pumps perform 4 simple functions:

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

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

three. Varying the timing relative to engine speed.

four. Generating the high fuel pressure required for injection

The Bosch VP44 is an electronic rotary distributor pump that can vary fuelling and injection timing, and also includes fuelling, timing, and alkaline antioxidant water investigation diagnostic data.

The number one trigger of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is typically due to a malfunctioning lift pump. Regular fuel pressure is around 15psi and if the pressure drops beneath 5psi an injection pump failure is probable. Remember bad lift pumps can run unnoticed till expensive damage is accomplished to the Bosch VP44 injection pump.

The following are the top two most widespread mechanical failures:

1. Examine Engine Code 216

This is the most typical mechanical failure and happens over a period of time when weak lift pumps, with low fuel pressure h2go on-line 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 able to bypass the piston. Dodge has recognized this problem for some time, and they no longer even sell the lift pump that goes on the side of the block anymore, rather they replace it with a unit that is now mounted in the tank.

2. Rotor Seizure

An additional mechanical failure with the Bosch VP44 injection pump takes place when the rotor seizes in the distributor section of the pump. The most common lead to for the seizure is a lack of lubrication. Considering that the fuel lubricates the Bosch VP44 injection pumps, weak lifts pumps can once again be blamed for this failure. The seizure will then break the Drive Plate and the truck will cease operating, never ever to start again, till the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The greatest way to stay away from failures of the Bosch VP44 injection pump is to avoid them from happening. Getting a replacement lift pump, one particular that is of a much better top quality than what comes from the factory will assist. If that solution is also expensive, 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 easily repair the dilemma prior to you lose the Bosch VP44 injection pump.

Preventing difficulties ahead of they take place is the finest way to take care of your truck.
