If you are seeking for a new injection pump for your Dodge Cummins diesel engine, but are not sure which is the finest model, than please continue studying. In this post we clarify some typical failures with injection pumps. The Cummins diesel engine manufactured by Dodge in between 1998 and 2002 came equipped with a Bosch VP44 injection pump. Regrettably these injection pumps have been know to have their fair share of issues and may possibly want to be replaced.

Bosch VP44 injection pumps execute four standard functions:

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

two. Metering the exact amount of fuel for each and every injection cycle

three. Varying the timing relative to engine speed.

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

The number one particular result in 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 negative lift pumps can run unnoticed until pricey damage is done 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 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 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

An additional mechanical failure with the Bosch VP44 injection pump happens when the rotor seizes in the distributor section of the pump. The most frequent 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 quit running, never to commence again, till the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The very best way to avoid failures of the Bosch VP44 injection pump is to avoid them from happening. Acquiring a replacement lift pump, one that is of a far better good quality than what comes from the factory will assist. If that alternative is too expensive, you can also install 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 difficulty ahead of you shed the Bosch VP44 injection pump.

Preventing troubles ahead of they occur is the greatest way to take care of your truck. alkaline water critique go there image
