If you are hunting for a new injection pump for your Dodge Cummins diesel engine, but are not positive which is the best model, than please continue reading. In this write-up we explain some frequent failures with injection pumps. The Cummins diesel engine manufactured by Dodge amongst 1998 and 2002 came equipped with a Bosch VP44 injection pump. Sadly these injection pumps have been know to have their fair share of problems and may need to be replaced.

Bosch VP44 injection pumps execute 4 fundamental functions:

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

two. Metering the precise amount of fuel for every single injection cycle

3. Varying the timing relative to engine speed.

4. Making 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 quantity a single lead to of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is normally due to a malfunctioning lift pump. Normal fuel pressure is about 15psi and if the pressure drops beneath alkaline ionized water 5psi an injection pump failure is probable. Keep in mind undesirable lift pumps can run unnoticed till expensive damage is done to the Bosch VP44 injection pump.

The following are the leading two most try kangen water machine typical mechanical failures:

1. Check Engine Code 216

This is the most widespread mechanical failure in english 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 till the fuel is able 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 anymore, 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 cause 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 stop running, never ever to commence once again, till 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 better quality than what comes from the factory will support. If that alternative is too 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 simply repair the difficulty ahead of you shed the Bosch VP44 injection pump.

Preventing troubles prior to they take place is the greatest way to take care of your truck.
