If you are searching for a new injection pump for your Dodge Cummins diesel engine, but are not certain which is the best model, than please continue reading. In this post we clarify some widespread 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 issues and may possibly require to be replaced.

Bosch VP44 injection pumps carry out four basic 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

3. Varying the timing relative to engine speed.

4. Producing the high fuel pressure necessary for injection

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

The quantity one particular result in of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is normally due to a malfunctioning lift pump. Typical fuel pressure is around 15psi and if the pressure drops below 5psi an injection pump failure is probable. Remember undesirable lift pumps can run unnoticed till costly damage is done to the Bosch VP44 injection pump.

The following are the prime two most widespread mechanical failures:

1. Check Engine Code 216

This is the most widespread 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 where it wears the housing of the pump down until the fuel is in a position 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 any longer, instead 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 occurs when the rotor seizes in the distributor section of the pump. The most widespread trigger for the seizure is a lack of lubrication. Given 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, never to start off once again, until the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The best way to avoid failures of the Bosch VP44 injection pump is to stop them from happening. Buying a replacement lift pump, a single that is of a greater top quality than what comes from the factory will aid. If that choice is also costly, you can also set up a gauge to monitor your fuel pressure. With the gauge you will be in a position to know when your lift pump is going out and can effortlessly repair the problem just before you lose the Bosch VP44 injection pump.

Stopping troubles prior to they take place is the best way to take care of your truck. vitamin c shower filter jupiter water ionizer site jupiter melody
