If you are looking for a new injection pump for your Dodge Cummins diesel engine, but are not sure which is the best model, than please continue reading. In this post we explain some typical 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 issues and might need to have to be replaced.

Bosch VP44 injection pumps perform four basic functions:

1. Distributing the high-pressure, metered fuel to each 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.

4. Creating 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 contains fuelling, timing, and diagnostic information.

The quantity a single lead to of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is usually due to a malfunctioning lift pump. Typical compound miter saw reviews fuel pressure is around 15psi and if the pressure drops below 5psi an injection pump failure is probable. Bear in mind bad lift pumps can run unnoticed until costly harm is accomplished to the Bosch VP44 injection pump.

The following are the best two most frequent 12 compound miter saw reviews mechanical failures:

1. Check Engine Code 216

This is the most widespread 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 till the fuel is in a position 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 anymore, as an alternative they replace it with a unit that is now mounted in the tank.

two. 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 common lead to for the seizure is a lack of lubrication. Given that 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 stop running, never to start again, until the Bosch VP44 injection pump is replaced.

Stopping Bosch VP44 injection pump Failure

The best way best 12 inch miter saw to stay away from failures of the Bosch VP44 injection pump is to prevent them from happening. Buying a replacement lift pump, one that is of a greater quality than what comes from the factory will assist. If that choice is also expensive, 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 effortlessly fix the issue before you shed the Bosch VP44 injection pump.

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