Rebuilding Ford 7.3 Powerstroke HEUI Diesel Injectors

[@Neverstopbuilding]

Not intentional, but it worked out that this content is a few years old. The truck is still going strong 226k miles as of February 2023. All the injectors still seem to be doing just fine.

[@lissettelopez8331]

Looks like I searched for" rebuilding Heui inejctors" just after your posted it. Great timing lol

The amount of different chemicals you expose your hands to is astounding. That's coming from a daily diesel mechanic.

[@silvergrizzly316]

Indeed. He's got a good video here but all those chems just soak into the blood stream. For a long time I thought if ya didn't have grease on your hands, you weren't working. But as I got older and understood the body a little better not to mention being warned about the toxic effects of all these oils have, I wear the rubber gloves now and when they tear I put on new ones.

@@silvergrizzly316 yup liver cancer on its way this guy needs nitril gloves one big time the damage is all ready done ,safety training in the airlines taught me right away the dangers of chemicals many co workers died already from cancers to there organs from previous exposure earlier in there lives

[@jbbolts]

@@atv55803 Yeh some have a delay and only affect you years later.... there are alot of nasty chemicals in products these days

[@EEnsign97]

What kind of gloves do you recommend that dont immediately breakdown and that still protect your hands?

[@PikachuG5]

The screws holding the solenooid and the poppet body are Torx Plus, and the one holding the aramture plate to the poppet valve uses what people usually call a game bit. It's apparently used on gaming consoles also.

[@jasonsejkora4578]

I found this video after looking at a Facebook marketplace. Add where a 7.3 needed. Injectors. Could have left in the first few minutes, but stayed to the very end. This looks like a lot of fun. Glad you got your truck going again. Cheers!

[@nando11220]

These injectors are insane! There's so many parts inside just one of those. I don't really wanna rebuild mine anymore.

[@Neverstopbuilding]

Aw you should, just stay organized, lot cheaper than paying someone or buying a new set

[@AmalgmousProxy]

For anyone watching, just use a pick to pull the piston out. The same pick will work for removing and installing the o-rings. Just be careful not to poke them.

Great video mate.....I too never where gloves especially doing small work like this. Yes it isnt good for you but nor is fatty food and car exhausts and im sure they kill way more people rhen a bit of oil and carby cleaner. Thanks heaps for the video....great work.

[@rileygoossen1299]

Air also works quite well to get that cylinder out.

[@middleclassthrash]

22:51 I remanufactured EUI injectors for years. We had a machine that forced this gray puddy shit they called media "I think it was impregnated with diamonds" through the spray tip holes. Also, we would machine the main valve seat, the body seat, the needle valve seat in the spray tip... This stuff was absolutely critical and you'd analyze the seats. So few of them would pass. In addition, we would measure the spring force with the whole stack of spray tip, needle, spring, shim to ensure it would allow the valve to open at the correct pressure. It's called tolerance stacking. How are you verifying this? It's been so long that I'm sure I'm forgetting things in addition to all this. I would not recommend anyone rebuild diesel fuel injectors. Maybe you'll get lucky I guess.

[@9432515]

Hi. I had the exact same thing happen to the nozzle on one after sonic cleaning and then assembly. Torqued to 75 ft lbs and as I was busy shimming the top, it just popped. Any idea what would cause this?

[@jimmyrig8971]

21:15-21:40 😝 i literally, laughed out Loud. Talk about a pucker-up! Thanks for a great informative video. This is definitely not a laughing matter. I dont know if im strong enough to tackle this project lol i commend you.

[@Bhunt13579]

Thank you for the info you got my sub will be coming back to this to do mine once I'm ready to tackle mine do you remember about what you spent on tools and new parts?

[@MikeLifeHack]

Thank you somuch for making this video Do you have Links for the tools you used. Specifically the Tweezer set and the.plastic Parts organizer. Thanks again

[@jamescucuro9125]

I have been using SEAFOAM in the fuel every other fill up. Diesel type. Will I have any bad impact on o rings at injecters ?

What size sonic cavitation machine did you use? I see many different sizes available.

[@haydensalles]

How much money do you save doing this yourself as opposed to buying new from a company like Full Force? Because damn, I don’t think I’m comfortable rebuilding them myself, this looks super convoluted

[@nellaob4229]

Just curious...before you did all this work, had you poured in one quart of transmission fluid into the diesel tank to see if that would clean the injectors enough to run good again? Excellent Video Sir!!!

[@SwappedByMetro]

What does pouring the trans fluid in the gas tank do ? I’m new to diesels

[@nellaob4229]

great video on rebuilding the injectors,, how does the truck run now!! :)

I was torking my second injector and I thought all was going well than the top of my nosel blow off what I found was that my little disk had slipped to the side and picked down at a angle witch put to of pressure on the needle forcing it to brake the nosel

[@iansteward4708]

So there was a noticeable difference after rebuilding them? Still holding up good?

[@romanesco123]

Question, where do you buy the parts from ?

[@helamanarrigo1249]

I’ve seen rebuild kits on eBay. Not sure of the quality tho

[@ChristopherBrown-s5h]

Do you run the master stages clean concentrated? Or do you dilute it?

[@budgetwheeler4x4]

I live in Michigan. How much would you charge me to rebuild mine 95 7.3

[@bad89coupe]

I'm doing this job for the first time and starting on my second injector after watching someone else's instructional video but you both put them back together oriented differently then you took them apart.... I'm not sure if I should take the first one back out and swap it or continue assembly the way you show 😥

[@mattm3492]

Put together the way it's taken apart

[@bad89coupe]

@@mattm3492 nope, indexed housing 180` on reassembly

[@mattm3492]

@bad89coupe so when you take something apart your supposed to put it together the exact opposite way? Ok gotcha 🤪

[@bad89coupe]

@@mattm3492 You could have just said, show me. But instead you want to act like a clown. So answer me this, at 6:56 in video when you lift off the plate, the drainback notch in the base is opposite the clamp "flat side" you refer to it as. Which is the direction of the connector, the top side, which makes sense because that's the bottom. But at 35:30 in the video, you line them all up with drain back notch at the top.

[@magmacoffee]

That thing looked in pretty good shape did it really need to be rebuilt?

[@Neverstopbuilding]

I’m thinking so it was having terrible starting problems and there was dirt and crud in the injectors and some broken springs if I recall. After this it had no problems
