At Highway and Heavy Parts, we know fuel systems and we carry quality parts from reputable suppliers to ensure you're getting the best. That's why we're proud to carry genuine Bosch components like this unit pump system for the Mack E7.
Want to know more? Today we're going to take you through how the system works and why purchasing genuine parts and components from Highway and Heavy Parts is the best choice for your diesel engine.
First we'll talk a little bit about how these types of systems work. So the electronic unit pump system we're looking at today is for the Mack E7. We often see these types of fuel systems on smaller diesel engines like compact tractors.
It's really an individual PFR. This component goes into the side of the block, and it runs off the camshaft. We may still have a camshaft but we've taken the injection pump and basically broken it down into six individual injection pumps that can all be serviced individually.
On an inline six pump system, if one part fails, you're still looking at pretty complicated repair. You have to tear it all down and you're probably looking at 9 to 10 hours time to rebuild the pump. This particular pump for the Mack E7 usually has two bolts and a fuel line. That means you can just pull it out and put a new one in. So you have a system that has better serviceability, less costs, and it's easier to diagnose issues with.
When the shift from inline to unit pumps began, it was probably most common to see them on Mack and Mercedes engines. These systems are more service friendly, especially for people who aren't familiar with pulling injection pumps off, timing the pump, and everything that goes into that repair.
Diagnosis is also easier as you can pull a piece off and swap it from hole to hole and see if the problem follows. This allows you to see where the bad portion of your system is.
We get a lot of calls from customers about their pumps asking:
How do I align up the gears?
How do I time the injection pump system?
And this takes away all those problems. With the unit pump for the Mack E7 you'll be getting long service life, easy and quickly adjusted injection quantity, and improved combustion. You also get improved compliance with emissions regulations.
