Rebuilding Ford 7.3 Powerstroke HEUI Diesel Injectors
HTML-код
- Опубликовано: 23 авг 2024
- The process used to clean and rebuild the HEUI Injectors common to the legendary 7.3 powerstroke ford/navistar engine. It's too expensive to buy replacements and most shops won't even rebuild them anymore. What a shame. I got through the whole process from disassembly to reassembly.

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.
Looks like I searched for" rebuilding Heui inejctors" just after your posted it. Great timing lol
@@lissettelopez8331 right on! It’s worth the effort.
Looks
Tidious
The amount of different chemicals you expose your hands to is astounding. That's coming from a daily diesel mechanic.
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
@@atv55803 Yeh some have a delay and only affect you years later.... there are alot of nasty chemicals in products these days
These injectors are insane! There's so many parts inside just one of those. I don't really wanna rebuild mine anymore.
Aw you should, just stay organized, lot cheaper than paying someone or buying a new set
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!
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.
Air also works quite well to get that cylinder out.
21:00 when the bucket handle broke😂😂
from Guatemala 🇬🇹 nice video I, like bless you America 🇺🇸 here and NJ
Thought I was watching a watch repair video
Excellent
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?
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.
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?
Good job !! Learned alot
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.
Thanks!
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
So there was a noticeable difference after rebuilding them? Still holding up good?
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!!!
What does pouring the trans fluid in the gas tank do ? I’m new to diesels
@@SwappedByMetro it will clean the fuel system, injectors and also lubricates seals. this is what I do in my older diesels. But I am telling you to do this,. *Do some research on it.
@@SwappedByMetrofuel tank. Google Atf for injector cleaner.
2002 power stroke 7.3, 327.000 miles on original injectors and I run atf
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
Question, where do you buy the parts from ?
I’ve seen rebuild kits on eBay. Not sure of the quality tho
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
I live in Michigan. How much would you charge me to rebuild mine 95 7.3
So do you have to have a parts washer
Do you run the master stages clean concentrated? Or do you dilute it?
That thing looked in pretty good shape did it really need to be rebuilt?
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
@@Neverstopbuilding that broken spring alone warranted refurbishing all 8, great job.
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 😥
Put together the way it's taken apart
@@mattm3492 nope, indexed housing 180` on reassembly
@bad89coupe so when you take something apart your supposed to put it together the exact opposite way? Ok gotcha 🤪
@@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.

You did the front wrong.....the U part belongs to the bottom part of the injector not the top at 35.34...look at 6.51 to see how the u is...
Oh man! You’re right! Good catch! I wonder if that makes any difference? I followed this video when I rebuilt mine. Now mine is running tougher than before I rebuilt them.
How long did removing the injectors take?
Oh man I forgot I’d have to look at the footage, maybe I got everything disassembled in a day
@@Neverstopbuilding 3.5 hours on mine
get video , make sure you have a 1/4 size universal for the left side fire wall bolt .
Annnnnnd now i will not be doing this myself.
Number one mistake never use metal tweezers or picks 👎
well what wold you use?... it's pretty standard practice
@@jbbolts if you have to ask, you don’t know what the hell you are are doing !
@@jbboltsthey do make the plastic tweezers that some people say to use, I got a set of them, the good ones!, and haven't used them on my injector rebuild yet but I was try'n them out the other night and found out there's no damn way these things will pull out some of those O'rings. I twisted the tip of one just trying it out on light duty work🤦♂️
@@silvergrizzly316 exactly.... theres no way even cheap steel ones probably wouldn't cut it
