If you are searching for a new injection pump for your Dodge Cummins diesel engine, but are not certain which is the very best model, than please continue reading. In this write-up we explain some common failures with injection pumps. The Cummins diesel engine manufactured by Dodge in between 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 could need to be replaced.

Bosch VP44 injection pumps carry out four standard functions:

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

2. Metering the exact quantity of fuel for every single injection cycle

3. Varying the timing relative to engine speed.

four. Making the high fuel pressure expected for injection

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

The number one trigger of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is generally due to a malfunctioning lift pump. Regular fuel pressure is around 15psi and if the pressure drops below 5psi an injection pump failure is probable. Don't forget undesirable lift pumps can run unnoticed until pricey damage is done to the Bosch VP44 injection pump.

The following are the prime two most common mechanical failures:

1. Check Engine Code 216

This is the most common mechanical failure and occurs 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 until the fuel is able to bypass the piston. Dodge has recognized this difficulty 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.

2. Rotor Seizure

Another mechanical failure with the Bosch VP44 injection pump takes place when the rotor seizes in the distributor section of the pump. The most frequent trigger for the seizure is a lack of lubrication. Because 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 stop operating, never ever to start once again, until the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The finest way to steer clear of failures of the Bosch VP44 injection pump is to prevent them from happening. Getting a replacement lift pump, one particular that is of a far better top quality than what comes from the factory will help. If that solution is also expensive, you can also install 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 very easily fix the problem prior to you lose the Bosch VP44 injection pump.

Stopping issues prior to they occur is the very best way to take care of your truck. inside alkaline water drops check out alkaline water filter tumbshots
