I believe both should be 145 amp units and I DR44G is the newer part number.
Ordered!
@RainmanRaysRepairs - Inquiring minds would like to know whether you are going to replace those Torx bolts on the fuel return lines? I know I would since you likely are not going to be able to torque them to spec now.
What amazes me is how you remember how it all goes back😊😊
Break it up in system components and it’s not that bad. Mostly just got to do it a few times and it’s not that bad. Everything goes back easily just a lot of work. Everything really falls into place it can really be easy. Ray is not afraid of work and he is knowledgeable of systems components.
Yeah it seems overwhelming but I just litterly did the cp3 and fuel regulator x2 on my 03 lb7 and it seemed so daunting but like you said if you break it up , there's not much to it , still some work but if you lay things out and have it organized and take pictures it's easy
If he forgets he can watch the video.
I began doing what he does. I used to worry about it and still couldn't remember where bolts and nuts went.
Lately I've done a number of in depth jobs that might take me a week or so to start putting things back together.
I've only got a small leftover parts bin.😊
My grandson, just graduated from aircraft mechanic school and it drives him crazy that I don't make little stick it notes or labels and set each thing aside.
That's a good work habit if he's fixing a plane, but I'll chance it on my own car.
When you do something over and over it becomes second nature to you!
Cute story about the crush washer. I was an Avionics tech in the RNZAF (Airforce), my repair was to re-fit a connector on the belly blade type antenna, that had been wiped off by a heavy landing (student pilot or Flying Officer if you like). The connector was also wiped off by the grass heavy landing short of the runway. No problem, simple fix, says the SGT, just take off the inspection panel under the seat reach in and extend the coax cable fit a new connector, and once the airframe guys have fixed the ripped metal fit a new antenna. Now this job is my first on this type of plane. So I follow the instructions, remove the inspection panel and reach in and come out with a handful of mud and grass, so OK I vacuum all that out, again reach in for the cable, got it. Pull it into view, but Its too short. Tell SGT, he tells officer in charge of maintenance, next thing I've got Base C.O and all the 'interested' officers looking over my shoulder, You sure you can't fit it? All eyes on me, "Well I say if I could get better access, I could un-loom it from there and move the coax out a bit and then it should fit" I heard myself say. "GOOD", says the C.O. and a nod from the Chief Flying training Officer. Now I have to say my rank, I was a brand new shiny Aircraftman, in short the lowest of the low with the sole exception of recruit. BUT, because I opened my big mouth, I now had to actually fix the problem, correctly, in military fashion, and following all the correct CAA (FAA equivalent) rules and regulations.
Luckily, I had just completed training on how to calculate the number and spacing of rivets and or rivinuts around a patch in the aluminium. So under the pilot's seat I cut a 12 inch square hole for access, drilled and fitted the rivinuts, made a new panel to fill the hole. All good, but this is the military, you can't just cut holes in the internal part of the wing box section, you have to do it on paper first, using the manufacturers diagrams, as a plan and make a "MOD" or Modification plan. So after a month or so of sketch, get approval, send to drawing dept, add many pages of 'how to', and then re-write so a shaved monkey can understand it, adding ten more pages and pictures (sketch, get approval, send to drawing dept) finally I was given the approval to cut the hole.
So I cut the hole, mark the places for the rivinuts. Shine my torch into the hole, and run away screaming, laughing and sit in the corner holding my head. This particular airplane was built with pop rivets, visible in the hole I cut, was many kilos (pounds) of pop rivet heads, all floating around inside the wing box section under the pilots' seat, just where the aileron control cables pass and the coax I was looking for. Much longer story short, I had to make three more Modifications two of which grounded the Aircraft type until completed. If anyone cares I'll tell you the type of plane and even now my mods are required for all of the type. After my mods the aircraft are lighter and a little safer. Also there is access to cable for the antenna to be 'wiped' several times more LOL.
I'm quite interested in this I would be pleased to know
cool story @andrew
Wow quiet a story hope they could streamline this process during combat !!but I enjoy any Aviation story ,it has to be done properly unlike a car you can't pull over to check 😮😮

Man as soon as I seen you say airframe guys I had to write haha. I was an airframe in the US Navy! I actually helped train people to work on the super hornet! VFA106E/F. I helped transition all F-14 squadrons to the super hornet on the east coast! Man I miss it 😢
@@kymw7833 Combat expedient is to yank harder on the coax. 👍
This video reminds me of the time I refilled my own washer fluid and put cap back on all by myself 😎
Excellent!!!
🤣 nice
That's a beginning ! 😅
C'est un début ! 😊
Sweat must have been dripping down your forehead.
But did you get the lettering in the right direction?
OMG! What an intimidating, daunting, and overwhelming job. It's like brain surgery. I'd be stressed to the max and nervous about breaking things and then have to struggle to try to put it all back together, adjusted, calibrated, and torqued correctly. I have so much respect for the experience, skill, and confidence needed to calmly work through this huge project.
I'm more impressed that Ray can keep up a running informative dialog for over an hour. That is amazing.
I bet he has to play back his video to put it back together
I would, but Ray is young and does this for a living...@@transformer889
Try changing spark plugs on a Fiat/Pugot 😂
YES!!!! Longer video. I look forward to these every day. I love working on cars and I enjoy the content. Thank you for taking the extra time to make videos. 👍🏻
Gonna start calling Ray the one hand bandit. It's truly amazing how he can do all this with just one hand : )
He can't he keeps dropping things, sooner or later he is going to regret it.
Every time I drop something I say gravity just like ray does. 😂😂
Remember to torque your return rail bolts to 1200 ft lb
I'm never complaining about the sounds of hard work in the background. The fortunate aspect of the granite guys is your mic picks up very little of it. I'm sure the stone saws bother you much more than it does the viewers.
When do we get to meet the granite masons? I was a hod laborer for a granite company many years ago -- learned a lot and it is heavy lifting
@@ab2230 Hope those guys are wearing the proper respirators. Nasty stuff causing, mesothelioma .

Thanks for not editing out the issues when things go sideways. I learn a lot from your problem-solving strategies. Thanks Ray!
I started working on vehicles in 1957. Taught at Nashville Auto Diiesel college for 5 years, then high school for 20 more. Nice to see someone do the job right. I love your videos.
Thanks Ray for the work on this series of the Durty max you are doing. I am learning alot from it. Thanks for taking us along on this massive filming and editing journey. We all appreciate the effort.
One of the great things about Ray's videos is watching them is like having a spirited and lively conversation without having to say anything...!
Keep at it Ray.... ... .. !
😁👍
I worked in R&D for 40+ years and conducted an 18 month project with 2 technicians, and designed 167 line Gantt chart of tasks and way more stage/gates than I care to remember.
BUT, I would never attempted what you have done here. You sir, can use my line...."The difficult I do right away, the impossible takes me a little longer."
Wow, the amount of disassembly would have sent me to retirement. It is great that you have all the necessary tools to be able to remove bolts, crews, and nuts.
Nice job ray, it's always fun to learn things about cars and diagnose/repair the cars issues. Keep up the great work. 😊
I was a engineman in the coast guard back in the 60s . Enjoying your video on the diesel, the engines I work on where alot larger, but just as fun,Haha
Looks like loads of fun, I don't know if I want to do all of that, I think I will sell my diesel first.
I've got one of these except it's a GMC Sierra. The injectors were an issue in the past but that's been rectified. Mine has 518,000 miles on it and still going strong.
Sell it or park it in a "bad area".
One person’s junk is another person’s treasure.
I'll buy it, sir.
@@Michael-yi4mc Giggety?
The totality of a job like this can overwhelm one when contemplating it. As you have said multiple times, "it's like pealing layers of the onion back" and it truly is. As I watched your progress, the difficulty became just that. It is a long and difficult job, one that comes with the territory of technician's knowledge and abilities. I learned a lot watching this first video. Truly not just as simple as "remove and replace injectors" is it? 😊
The ending of that video was so sweet. Lauren's closing got me a laugh. Lauren, you're so precious!
People wonder why i love the 6.0 powerstroke. The braid of coolant, wires, fuel lines and components just stacked on one another and the number of times ray had to change sockets or tools just to get the valvecovers off explains it all.
6.0 might have known repeat failures but its known and very easy to work on.
We used to pressure test the injectors on the Deutz diesels at Atlas Copco. We had a device with gauges we could pump in fuel ..
This dude is quicker and better with one hand than most of us are with 2 hands!
I'm glad you are here too!
I'm just amazed of the work that needs to be done to get to the fuel injectors. Outstanding work. Can't wait to see part 3.
Besides replacing the high pressure fuel lines, also replace all injector hold down bolts!! And suck out all fuel, from top of pistons
Hey Ray that was far more entertaining than watching you jump start it and park it 👏🤣
I did this very same job on my 2003 GMC Sierra 2500 back in 2009. It was just as intimidating to tackle, and it took me 5 days to complete, working after my day job. It is nice to see Ray doing it the way it is supposed to be done. Thanks Ray!
I am glad to see you doing an LB7. I own one. My injectors were replaced at around 60k miles under warranty. My truck has 114k on it now. I think GM had a recall on the original injectors. The original injectors had a problem for sure. To anyone who owns a diesel, keep your fuel filter changed and only put diesel in your truck from a high volume supply. I lost my diesel mechanic for health reasons. I have been looking for someone I can trust to perform work on my truck. I live in Atlanta it would be a long drive to your shop that is really too bad. I do not let just anyone work on my truck. I would let you work on my truck. I think that is the greatest compliment I can give you. I love all your videos and have watched all of them. Keep up the great work.
I'm so glad you are doing the lb7 because I am about to embark on the same procedure with mine and I,m not a certified mechanic!! Thank you for all the direction!!
Nice job Ray, its always a pleasure to watch you diagnose/repair car issues😊
For a while there, when you were failing at removing the return line bolts, my heart sunk into a pit of hopelessness. Not knowing about the existence of those specialized bolt extractors, the only thing I could think was, "What would A-rod do?" Glad things worked out for the best. I would NEVER, EVER, in many lifetimes, take on a job like this.
WOW, what a project. Ray, thanks for being a good human, for not being perfect and not acting like you are perfect, just darn good at what you do. Your videos are a daily part of my routine. Keep doing what you are doing.
Im not a mechanic but i completely get the reference about doing something the 2nd time in lightning time like a superpower. Maybe because the fasteners are already loose or because you have all the tools out even that one socket for that one oddball bolt size either way ive been there it made me chuckle.
Allen or hex fastener, I learned in Coast Guard aviation maintenance to call them internal wrenching fasteners.
Commenting for the algorithm!
Time to start the day with a cup-o-joe and a vid from Ray!
What a job this is! Youre a saint ray! Patience is definitely a virtue!!!
Hey Ray, when you said you were scared, I would have been scared with the harnesses. The mechanical part no problem. Glad I never had to work on a stinking diesel much.
We have our differences, but thank you CZcams for making a simple guy like me watch something as good as this video. I would never have this opportunity otherwise. Thanks Ray, you make my day every day! I wish your business much success in 2024!
Hello Ray. Rocket Surgery level 99.6. This is a tough one indeed.
25:21 It is an Allen. Funny story, when I got to my second ship one of my first jobs was to unbolt a head on one of the cargo wenches. It was nut coming off. When I told my supervisor I was told I did not know how to use an Allen wrench? So I said then they need to show me, they ended up twisting a 3/4 inch wrench like a candy cane, I kept it.
I do know that sinking feeling when fasteners start stripping. I appreciate your honesty and good attitude.
I used to watch live medical surgeries being performed that were televised on local TV stations, KERA/PBS was the channel if I recall. This reminds me of that. Thank you for this fun adventure.
I have been an industrial mechanic for 20+ years. I have extracted a good many stripped hex head cap bolts by hammering in a slightly larger sized torx bit. Sometimes you sacrifice the bit, but it works most of the time.
Bungie the hose Ray. Get into a groove of using bungies to help hold back hoses n wires. Much faster and better all around for you...
Part 3 ? I’m getting a part 4 vibe!😳
Please lord don’t make him have to do it twice, if there’s a missing crush washer I may need therapy!!😂
I have done my LB7 injectors twice (stealership also did them twice under warranty). Seal the injector fuel lines with some silicon after installation to prevent water getting in.
Will DO! It' be the few times ill use the clear
Got tired of allways doing injectors on my LB7, just bought brand new Bosch ones from Duramax store, they are pricey but haven't had to do another injector since. I have new injector bodies with 45% over nozzles and dual S and S super sport CP3's, wagler stage 2 cam, with a billet 64mm, studs, head gaskets, wagler high pressure oil pump, fluid damper harmonic balancer $12k in the stock motor and another $7500 in trans with all updates and billet Torque convertor, all silicone lines, welded water pump, love this truck, just needs a 6spd conversion and believe it.....she gets down even being a 2wd, she will surprise any sports car from a 30mph roll, hard to get traction from a dig.....still weighs 9K
This break down gave us a better understanding on injectors replacement,see you on part 3
That's a lot of work I can't remember all this to put back together 😮
I've reused steel fuel lines to injectors many times and never had any leakage problems
Thank you! I didn't know such a tool exists as the bolt extractor socket, I will be buying a set, probably both metric and SAE, personal use. I like how you video and explain in detail.
I JUST GOT that extractor socket set for Xmas. Glad they worked for you!
Manufacturers say the high pressure fuel lines need replacing but I've never replaced a hpfl and never ever had one leak, just check the mating face on the injector line where it mates with the inlet on top of the injector to see if it has and ridges around it where the nut has been wound down to tightly, all I work on is diesels I couldn't tell you the last time I worked on a petrol engine but whenever I do it makes it feel like I'm on holiday makes a great change.
Hi ray just let you know you’re video is never to long just finished watching video it was awesome don’t know how you don’t forget you’re Genius hi wife unit and Dave 🇺🇸🇺🇸
Yes!!!! Another long video!! 🎉🎉
Been there, we stayed in a Rv park for years in Fla , with our camper . It was a 2012 fifth wheel . After being at the same park for 11 years were told we were no longer be able to use our camper there because of age of the RV. Like you ,our RV appearance was excellent . We quit traveling and sold our camper and truck. We are now $80,000 to the good and independent of the RV community. We found that a lot of RV parks were becoming to have ridiculous rules and less friendly .
. We do miss traveling but now take monthly trips. We are in our late 60s and enjoy doing different excursion's now. So different world today. So sad.
Good luck to you and your family they look adorable.
Lauren spiked the coffee with pure love.❤️
G'day Ray, I listen to your vids on a stereo system. The concrete cutting is not a problem at all. If you hadn't mentioned it I would not have paid it any attention. Cheers from Oz.
Good work Rey. It has definitely been apart before. The factory sealant is grey on the upper rocker cover. They are much easier to come apart when someone hasn’t over torqued all the fasteners. Now you can do the more difficult side🤣. Thanks for the content. Bringing back a lot of old memories on doing these
If those copper washers are aything like those used on old motorcycle brake systems you can anneal them. Once used they work harden, if reused as is they may not seal. Annealing softens them back to an as new condition. This is done by heating the copper washers red hot and let them cool off. Either air cooled or quenched works.
Many times i have had to do this to get a good seal. New replacement washers don't always fit those old lines. Annealing the old is the only way to get a good seal.
Hey ray thank u for the videos its helping me right now i have such a bad chest infection thanks ray
The design with diesels is absolutely nuts. Very intricate work
As, always, just amazed you can remember where everything goes back. Hi to wife unit!
Well Ray, now I know what I'm in for, my dad's truck i got after he passed away, 2002 6.6 Duramax the injectors need replacing and an good servicing. Thanks for sharing this video, very informative, really glad to watch and look for the crush washer your 100% right we don't want to have things floating around in our engine.
There was a time when I could do a set of those in 8 to 9 hours, start to finish. Could even remember the torques for them . I never liked working on them because the farmers were rough on them . Learned to check all farm trucks for intercooler leaks every time one came in. Good video so far .
WOW!! Now that is a lot of stuff to move just to get to the injectors!! I need to change my battery in my Escape, really don't want to tackle it!! Vehicle manufactures are making things so you can't work on them!! Stay safe & Happy New Years!!
It's nice that you show that things don't always work out for you. as I work on my own older cars(64 Falcon and Bronco...). destroying nuts. Just to get them off seems to be common
Has anyone else noticed what looks like a crack in the alternator bracket at 46.45 47.18?
I cannot understand how corporation can get an engineer to design something like this. You are a wizard. Thank you for all the things that you're teaching me about these cars.
I was stressing out when you dropped that crush washer but felt better after hearing how important it is to find it!
Japanesium, good job at handling the snags Ray.
Hex or Allen bolt the answer is yes! Dayum still using flat blade on hex hose clamps! Flat blade screwdrivers are only good for opening paint cans! Great video! Curious to what a set of injectors cost!
I’ve done repair projects, mostly on motorcycles. There’s nothing worse than having a part left over. You won’t sleep until you figure it out.
If you do it for twenty years and more, you just don't give a f*ck. You just file it under "weight reduction".
Edit:
If a big a$$ high strength fine thread bolt is left over, it is a different story, of course!
Had similar recently on my valve cover replacement it’s a plastic valve and part was broken. Got it off to replace there was a piece of plastic just small enough to block the oil passage to sump. Long screwdriver poked it through it’s now either in the sump or filter no issues with engine running 😅 1.6tdi CAYC
Thank you Ray for once again reminding me of why I have no use for a diesel in my life.
Great video I can see why you change them all when in there. I have a2003 Ford F250 with the 6.0 had one injector bad on drivers side I replaced them all on thet side. Much easier than on your truck. Cummins is probably the easiest.
I remember doing an 8v71 in my dump truck time consuming no hurry work you’re doing great job
Delco Remy DR44G is the 145 amp alternator. Standard alternator is 105 amp.
Reminds me of helping my dad tear down a motorcycle engine to replace the pawl that engaged when you kick start the engine. When we got it back together we had an extra screw. Never did figure out where it went. Engine and bike ran fine.
I believe the difference in the alternators is the voltage regulator connectors one is 2 pin and one is 4 pin.
Hell I remember Army mechanics trying to service Hmmwv's and extracting glow plugs and them breaking and they punched them back into the engine then put new glow plugs in, started the engine running the glow plug through the cylinders and out the exhaust! clankity clank! 25th ID!
the amps of differnt alternators can be fitted to the truck like the dr44g has higher input the standard has lower the dr44
That’s why I’m kind of glad I got a 6.0. All 8 injectors is only like a 7 hour job and that includes doing stand pipes and dummy plugs.
If socket extractor didn't work. You could use Knipex cobra piler. Which design for round stuff. If you turn it, it will grip it tighter. Not like a normal piler. Other brand got it too but i only get to use knipex and it help me alot.
Now we know why it cost to have a good mechanic available to us and why it cost as much as it does to get something’s done. Here is proof why the book says it takes 12.9 hours to remove and replace the injectors on an LB7 6.6 Duramax Diesel engine. Not to mention all the different and often specialized tool needed like the turbo socket used on those stubborn return line fasteners..this is one particular job I personally would never try to do, well worth the funds to have it done right.
Keep up the great work and the excellent videos of the work being performed and all the troubles associated with it.
Thank you RainmanRay for this interesting informative conversation of Diesel engine fuel injectors you are correct this is indeed a very good video
blessings to you and yours , imop this is likened to watching a heart surgeon perform life saving surgery your narration is also great .
I don't even work on diesels. Watched the whole thing. 🍻
Nice work, LOTS of @non-extra” parts!! Tricky job
@Wife Unit - It's nice to see a lady who doesn't cover her beauty with paints and powders.
Love a full teardown! I didn't even mind that it ran long!
You never seem to get mad 😮 and never give up on a job😅 bravo RAY bravo 😅
Glad you're doing this job; I sure don't wanna.
knowing that you like efficiency, the ac compressor could have just been removed from its mounting and laid upside down on the passenger side battery on a fender mat for padding. And, unless you are going after the cp-3 pump, the alternator didn't have to be removed.....but that is just what I have done many times. if you ARE going after the cp-3 as well, then crack on.
Ray, thanks I never saw diesel injectors before now. I was on the edge of my seat (like a Hitchcock movie) when those bolts were stripping out!
WOW! That was really wild! Scary bolts! That was the shortest 1:15. Never a dull moment. 👱♀️
Great job Ray
Wow Ray that's a lot of work to do 😮
