If you are seeking for a new injection pump for your Dodge Cummins diesel engine, but are not confident which unbelievable deals is the finest model, than please continue studying. In this post we clarify some frequent failures with injection pumps. water ionizer The Cummins diesel engine manufactured by Dodge in 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 want to be replaced.

Bosch VP44 injection pumps execute 4 basic functions:

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

2. Metering the precise quantity of fuel for each injection cycle

three. Varying the timing relative to engine speed.

four. Creating the high fuel pressure needed 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 1 trigger of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is usually 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. Bear in mind poor lift pumps can run unnoticed until expensive harm is done to the Bosch VP44 injection pump.

The following are the prime two most frequent mechanical failures:

1. Check Engine Code 216

This is the most typical 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 until the fuel is capable 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, 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 widespread vitamin c shower filter trigger for the seizure is a lack of lubrication. Considering that 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 stop running, in no way to commence again, till the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The very best way to stay away from failures of the Bosch VP44 injection pump is to prevent them from happening. Buying a replacement lift pump, 1 that is of a far better quality than what comes from the factory will support. If that solution is as well 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 very easily fix the problem ahead of you shed the Bosch VP44 injection pump.

Stopping problems just before they take place is the very best way to take care of your truck.
