If you are searching for a new injection pump for your Dodge Cummins diesel engine, but are not positive which is the best model, than please continue studying. In this report we clarify some typical failures with injection pumps. The Cummins diesel engine manufactured by Dodge 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 problems and could need to have to be replaced.

Bosch VP44 injection pumps execute four basic functions:

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

2. Metering the exact amount of fuel for each injection cycle

three. Varying the timing relative to engine speed.

4. Generating the high fuel pressure expected for injection

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

The number a single cause 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 about 15psi and if the pressure drops below 5psi an injection pump failure is probable. Remember poor lift pumps can run unnoticed until costly damage is carried out to the Bosch VP44 injection pump.

The following are the top two most frequent mechanical failures:

1. Examine Engine Code 216

This is the most frequent mechanical failure and happens over 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 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 happens when the rotor seizes in the distributor section of the pump. The most common cause for the seizure is a lack of lubrication. Because 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 operating, by no means to begin once again, until the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The best way to stay away from failures of the Bosch VP44 injection pump is to prevent them from occurring. Purchasing a replacement lift pump, one that is of a better good quality than what comes from the factory will support. If that option 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 very easily fix the difficulty just before you lose the Bosch VP44 injection pump.

Stopping difficulties prior to they take place is the best way to take care of your truck. ionways review go here view site
