Hey Eddie, I'm your neighbor down the street. We are in Oklahoma right now and our new Ram Rebel with only 8k miles on it just had the CP4 explode on us. The 2021 and 2022 ecodiesels do not have the recall on them yet. However the warranty is covering the repair. Just an FYI to everyone with this fuel pump, you will hear the pump making clicking sounds if it's failing. It will sound just like a ac condenser clicking on and off.
Spring tension is supposed to keep piston rollers from spinning that’s why lubrication is crucial. Water, bad fuel priming or aeration in fuel pump can damage all pump components.
I buy a $70k+ truck and find out that they cut costs and purchased cheaper pumps to run fuel. I would have paid $1000-$3000 more if it meant that I got a good pump.
This is why every 3 rd tank i add marvel mystery oil and powerservices fuel treat keeping everything lubricated and 300 k on my 2018 ram And frequent filter changes no issues
I got mine back with the upgraded CP4 after my stock one failed at 10k miles...2 months later the second one failed too!! Hope you have better luck than I.
bought a 2020 2500 limited MFR date 7-20. I put Archoil in every tank, I am more than confident with my purchase. I have the CP4.2 new style. I also don't typically go below 1/4 tank of fuel to reduce cavitation. I would pay the dealer for a CP3 though if it was an available option.
There is no evidence that the updated cam version of the CP4 is any less of a POS than the older style. The design is fundamentally flawed. You made the right move. My '19 is stock, and I don't want to hose my warranty.
To ease the anxiety a little, it is not easy for the piston and roller to rotate! Imagine the roller half way up the cam contour then, in order to rotate, one side of the roller will have to roll higher up the contour and it is not free to do this because of the spring pressure holding it firmly against the cam. Only, and momentarily, when the roller is precisely at the top or the bottom of the cam will it be technically free to rotate - providing a force exists and it happens instantaneously before the roller starts its next ascent or descent. This is not a realistic scenario. I would guess that if a pump ends up with its roller skewed by 90 degrees it's because other failures have preceded it, such as debris jamming or giving rise to friction in the piston walls and the piston therefore losing engagement with the cam. The problems many of you guys are experiencing in the USA I believe have been caused to a great extent by fuel quality issues. I drive a Macan S Diesel in the UK and there are very few problems reported with these pumps. They are also widely used in many vehicles worldwide in CP4.1 and 4.2 form and, again very few failures reported. However, I can totally understand the concerns, even misery, of many of your viewers trying to resolve matters which ought to be resolved by manufacturers. Nice video with good clear pictures of internal parts. Thanks
Great explanation of the piston and roller dynamics in relation to the cam. I had been trying to visualize the engineering dynamics in my mind and knew it had to be something like as you described. For the most part all I kept running across were videos of individuals expressing the incredulity of an engineered part that functions against the logical mind. It makes total sence now. It is unfortunate there has been so much grief caused due to an engineering that has zero tolerance for subtle anomalies.
While I agree with both of y’all’s analogy… In 2020 the CP4 pump for the Ford Powerstroke got screw in alignment dowels for both pistons. Obviously to prevent rotate. I wonder why though.
I heard about hundreds of bmw and vw equipped with CP4.1 and CP4.2 failed in Europe... Many of them were using premium fuel, but it didn't prevent the failure at all. So it has nothing to do with the fuel quality unfortunatelly...
My truck would drag that truck up and down the road. Hands down smoke it in a race. It’s proven those trucks do not like added power, there trans suck even the almighty aisin, Eddie himself says his trans doesn’t like it. Better get rid of that before more money is wasted.
Bucket can rotate in the bore, it does not do that very often. The reason I think, is the spring keeps pressure on the bucket. And the roller as it interfaces with the shaft cam wants to naturally align as it comes together to push the bucket up. What happens is score or wear forms on the roller-cam, one side or the other. That produces a side vector force and one side of the bucket roller drags compared to other side and it twists out of alignment. Of course then, it can wear a flat spot in the roller and cam and it never goes back aligned right again, and it disintegrates. It is a very poor design for sure.
How many miles were on that pump? I have a duramax with 200,000. On it. I was amazed how clean your pump was. Seemed fine to me. Thinking of swaping tho the cp3. Iv been traveling around the US pulling a 5th wheel camper. This is the only thing I think about on the long drive. Having my cp4 fail 18 hours from home.
I have had issues with both my bmws with the cp4 pumps. On my 2009 E88 120d I fitted a 2018 cp4 pump with has a screw in the back of the pump which will prevent piston/cam roller rotation.
I found that B47 engines are equipped with updated pumps from year 2017 onwards. But need to fit the pump head from an old one to fit it on N47 engine. HP fuel outlet is on the opposite side...
The CP4 is the best of the best. They fail because of water and lubricity. The issue is the water!!!!! Long live CP four and the best throttle response and economical fuel delivery !!!!
I have a 13 Powerstroke. My pump was upgraded under warranty back in 2016. Ford starting using an updated version in 15 MY trucks. I didn't have the pump out, but was able to see "Bosch 4050" stamped on the back side. Do you think this means I have the updated one? Every pic of a 11-14 pump I could find has "Bosch 4000" stamped and 15+ have 4050.
Eddie I was trying to find the video where you swapped it out with a CP3 and could not find it. What all did you have to change out to complete the swap and did it have to be reflashed? Thanks
It's not true that there is nothing that prevents the roller from spinning: Maybe difficult to understand, but as long as the roller is pressed down to the cam, the cam itself prevents the roller from spinnng. For sake of accurancy: there are two positions of the cam where spinning isn't prevented:these are the most "upper" position of the cam and the lowest position. But these are very short periods compared to the whole revolution of the camshaft.
@@EddieLife3500 yes, i've seen such cases too, but that can't be the primary fault, because the roller cannot spin, as long it is in contact with the cam. So i assume this: the (cylindrical) "roller housing" gets stuck somewhere near the head and THEN it can spin. My pump is a 2015 and it has 6 small dimples and 1 large one.
So I have herd when they let go it’s caused buy to things, lack of lubricity or the dam roller goes side ways no I’m not sure if because of lack of lubricity it causes that but I have seen quite a few when they open it up it is turned the wrong way
Has anybody ever provided with a definition for diesel fuel lubricity beyond just the words? what is the causal mechanism for poor diesel fuel lubricity?

Dumbest design ever! And then after all the failures, you would think they would learn and clock those pistons with a key way or flat side to keep from rotating in the bore. Instead they just keep selling us crap with fingers crossed.
There is so much that could be done with these pumps that could solve the piston spin problem . Even a ball bearing instead of a roller would have let these pump not have the serious stupidity effect .

Aeration is what's killing these pumps. Debris doesn't help for sure but usually air. They aren't long for the world with any bubbles in the fuel.

I'm sure there's a handful of folks that would like to meet their team!
Shop is just as messy as mine. This how u know when u see a real mechanics shop
Ford needs a cp3 conversion kit, they make a kit to run a cp4 and cp3 together but I’d like to be able to completely bypass the cp4 and only use a cp3
One of the many reasons I bought a leftover 4th gen last year, didn’t want to deal with the cp4
Just bought a leftover 2020 5th gen so glad I’ve got the updated one hope it lasts

Your pump is not the updated one. It would have a stop bolt on the back to prevent piston to spin.
