If you are hunting for a new injection pump for your Dodge Cummins diesel engine, but are not athena water discussion confident which is the very best model, than please continue studying. In this post we explain some widespread failures with injection pumps. The Cummins diesel engine manufactured by Dodge among 1998 and 2002 came equipped with a Bosch VP44 injection pump. Regrettably 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 standard functions:

1. Distributing the high-pressure, metered fuel to each and every 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. Generating the high fuel pressure necessary 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 data.

The quantity 1 cause of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is usually due to a malfunctioning lift pump. Normal fuel pressure is about 15psi and if the pressure drops beneath 5psi an injection pump failure is probable. Remember bad lift pumps can run unnoticed until costly harm is carried out to the Bosch VP44 injection pump.

The following are the prime two most widespread mechanical failures:

1. Examine Engine Code 216

This is the most widespread mechanical failure and occurs more than 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 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

An additional mechanical failure with the Bosch VP44 injection pump occurs when the rotor seizes in the distributor section of the pump. The most common cause for the seizure is a lack of lubrication. Because the fuel lubricates the Bosch VP44 injection pumps, weak lifts pumps can once more be blamed for this failure. The h2go seizure will then break the Drive Plate and the truck will quit running, by no means to start off once more, till the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The greatest way to avoid failures of the Bosch VP44 injection pump is to avoid them from happening. Purchasing a replacement lift pump, one that is of a far better quality than what comes from the factory will assist. If that alternative is as well pricey, 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 effortlessly repair the issue ahead of you shed the Bosch VP44 injection pump.

Preventing close remove frame troubles prior to they take place is the finest way to take care of your truck.
