Info on Bosch VP 44 Diesel Pumps for Diesel Trucks

If you are seeking for a new injection pump for your Dodge Cummins diesel engine, but are not certain which is the best model, than please continue reading. OTC Rear Axle Bearing Puller Set - OTC7494A - 1800CheapTools investigate axle bearing puller. In this write-up we clarify some prevalent failures with injection pumps. The Cummins diesel engine manufactured by Dodge in between 1998 and 2002 came equipped with a Bosch VP44 injection pump. Unfortunately these injection pumps have been know to have their fair share of issues and could need to have to be replaced.

Bosch VP44 injection pumps perform four fundamental functions:

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

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

3. Varying the timing relative to engine speed.

four. Creating 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 consists of fuelling, timing, and diagnostic information.

The number one cause of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is typically due to a malfunctioning lift pump. Lisle Corp. Stepped Pickle Fork Kit - LIS41400 - 1800CheapTools pickle fork. Standard fuel pressure is around 15psi and if the pressure drops below 5psi an injection pump failure is probable. Bear in mind negative lift pumps can run unnoticed until pricey damage is carried out to the Bosch VP44 injection pump.

The following are the top rated two most common mechanical failures:

1. Check Engine Code 216

This is the most common 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 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, rather they replace it with a unit that is now mounted in the tank.

2. Rotor Seizure

Yet another mechanical failure with the Bosch VP44 injection pump happens when the rotor seizes in the distributor section of the pump. The most common cause for the seizure is a lack of lubrication. Given that the fuel lubricates the Bosch VP44 injection pumps, weak lifts pumps can once more be blamed for this failure. The seizure will then break the Drive Plate and the truck will stop running, by no means to start once again, till the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The best way to steer clear of failures of the Bosch VP44 injection pump is to prevent them from happening. Purchasing a replacement lift pump, one that is of a better high quality than what comes from the factory will aid. If that alternative is too expensive, you can also install a gauge to monitor your fuel pressure. Thexton Adjustable Ignition Spark Tester - THX404 - 1800CheapTools thexton. With the gauge you will be able to know when your lift pump is going out and can easily fix the problem before you shed the Bosch VP44 injection pump.

Stopping difficulties prior to they occur is the best way to take care of your truck.
