If you are seeking for a new injection pump for your Dodge Cummins diesel engine, but are not certain which is the finest model, than please continue reading. In this article we clarify some widespread 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 concerns and may possibly need to have to be replaced.

Bosch VP44 injection pumps execute 4 fundamental functions:

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

two. Metering the precise amount of fuel for each injection cycle

3. Varying the timing relative to engine speed.

four. Generating 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 includes fuelling, timing, and diagnostic information.

The number one particular cause of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is typically due to a malfunctioning lift pump. Regular fuel pressure is about 15psi and if the pressure drops beneath 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 typical mechanical failures:

1. Check Engine Code 216

This is the most common 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 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

One more mechanical failure with the Bosch VP44 injection pump occurs when the rotor seizes in the distributor section of the pump. The most widespread lead to for the seizure is a lack of lubrication. Because the fuel lubricates the Bosch VP44 injection pumps, weak lifts pumps can yet again be blamed for this failure. The seizure will then break the Drive Plate and the truck will quit running, never ever to start off again, till the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The best way to keep away from failures of the Bosch VP44 injection pump is to avert them from taking place. Acquiring a replacement lift pump, one that is of a far better quality than what comes from the factory will assist. If that solution is also pricey, you can also set up 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 easily fix the problem prior to you shed the Bosch VP44 injection pump.

Stopping problems ahead of they happen is the best way to take care of your truck. my water ionizer tyent uce-9000t relevant webpage
