If you are searching for a new injection pump for your Dodge Cummins diesel engine, but are not positive which is the finest model, than please continue reading. In this write-up we clarify some typical 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 might require to be replaced.

Bosch VP44 injection pumps execute 4 fundamental functions:

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

two. Metering the precise quantity of fuel for each and every injection cycle

three. Varying the timing relative to engine speed.

4. Generating the high fuel pressure required for injection

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

The quantity a single trigger of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is normally 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. Keep in mind undesirable lift pumps can run unnoticed till pricey harm is carried out to the Bosch VP44 injection pump.

The following are the leading two most frequent mechanical failures:

1. Verify Engine Code 216

This is the most widespread 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 where it wears the housing of the pump down till the fuel is capable 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 any longer, as an alternative they replace it with a unit that is now mounted in the tank.

two. Rotor Seizure

One more mechanical failure with the Bosch VP44 injection pump happens when the rotor seizes in the distributor section of the pump. The most common lead to for the seizure is a lack of lubrication. Given that 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 cease operating, in no way to start again, until the Bosch VP44 injection pump is replaced.

Stopping Bosch VP44 injection pump Failure

The greatest way to steer clear of failures of the Bosch VP44 injection pump is to avoid them from taking place. Getting a replacement lift pump, one that is of a better top quality than what comes from the factory will help. If that solution is as well expensive, 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 simply fix the dilemma before you lose the Bosch VP44 injection pump.

Preventing issues ahead of they happen is the best way to take care of your truck. copyright copyright life ionizer 9100
