Great video! You do a great job of explaining things.👍

[@MeanBee392]

Thank you very much!

[@byronstaten3452]

I like your tip on using old fuel line to remove the injectors... thank you I was stuck on the far back injector on the the left side....

[@MeanBee392]

You're welcome and glad that tip was able to help you out! It does make it nice to have something to grab onto and especially on that back one because it is a pain! Thanks for letting me know this video was able to help you out! 🐝

[@alexrohrbaugh9683]

thanks for these videos, appreciate you showing me how to fix my truck

[@MeanBee392]

You're welcome and I am glad to hear that they have been helpful for you!

[@rickarcher9886]

You are the man!, lol. Great how to video . That job would’ve had me in a rubber room in 10 minutes, lol. Great job buddy. Thanks for the video and your time

[@MeanBee392]

LOL thanks buddy! LOL yeah it was a big job but it was a lot of fun and I love to mechanic so it was right up my ally! Thanks friend I appreciate all of your support and I hope you have been doing well!

[@michaelmatsumoto4956]

Bro I must be A-D-D that is a lot of stuff to take off 😳 lol WOW I have an 02 LB7 I believe I'll just hand it over to a pro !! My hats off to you sir !! Hell I'm 65 anyway can't stay bent over that long u did a perfect presentation !! That's why the pro's make the big bucks

[@thecrazyfoolaffle]

[@robertnorton5985]

Much appreciated. Doing the job myself. A little intimidating. Video is very helpful

[@MeanBee392]

Hopefully it went smoothly for you and my video has helpful for you. It can be a bit intimidating but take your time and keep a clean work area and it will go good. Thanks for watching and commenting!

[@filibertodelgado4077]

How’d it go

[@robertnorton5985]

Went well. Took my time about three days worth. Definitely good to take your time.

Excellent video!!!!!

[@MeanBee392]

Thank you! Hopefully you found it informative. Thanks for watching and commenting!

[@megastick9324]

It’s a big job to be sure. On my 02 I’ve done the injectors, glow plugs, water pump, CP3, hydroboost and AC. I should’ve done the CP3 when I did the injectors looking back. I had over 200k when I did injectors, and pretty much everything was out of the way. Same when I did the FPR, I was nearly there when I did injectors. My advice is, if money permits, when you do injectors, do the CP3 and FPR at the same time, you’ll save SO much time over doing the same stuff over again. Also, replace ALL rubber lines you come across as you go, you’ll be glad you did when the old rubber lines don’t leak after all that work. Set aside a couple long days, don’t rush. It’s in your best interest to replace anything questionable while you have the stuff out of the way, it beats doing a lot of it 2-3 times.

[@MeanBee392]

That is great advice and I would agree as long as money permits like you said. Thanks for your comment!

[@biggunsnu]

Fantastic video. Only question I have is how do you use that tool for the lines that has the push release? Looks like a bunch of multi colored collars in a holder.? Thanks for the video.

[@MeanBee392]

Thanks and sorry for the late reply. It is a bunch or multi colored collars that are sized to the lines in color coronation. You just take the right sized one and push it up into the fitting and it will release the internal fingers and allow you to pull on the line to remove it. Hopefully that helps!

[@dirtrider292]

Fantastic tutorial

[@MeanBee392]

Thanks and glad you enjoyed it! Thanks for watching and commenting!

[@kincaidantolin]

Great videos currently doing the sac installation and had a question. Any suggestions on removing the valve cover bolts against the firewall they are giving me hard time. Thanks again for the videos It’s a big help while I’m doing the install

[@MeanBee392]

Are they giving you a hard time by not having enough room or did they strip out? If it is because they are tight to get to I found that a 1/4 drive with a universal joint really helps getting to them. That's great to hear that you are finding the videos helpful! Thanks for taking your time watching and commenting!

[@yiction]

@MeanBee392 studying up to attempt this repair, this video is incredibly helpful. Let's say the bolts against the firewall were stripped - what would you suggest to get those out?

[@krisenders9924]

How are you liking your LDS injectors?

[@mattguarro1434]

Good job!!

[@MeanBee392]

Thank you and hopefully it was helpful! 🐝

[@Modernexodus1]

Thank you for taking the time to make this! Great job. I have an 02 lb7 that runs great, but I know that at some point will have an injector go bad. I'm an intermediate mechanic but have never done done anything this extensive. I am thinking that I want to do this job with my son's so they learn as well. Do you think this job is doable if you're not a pro mechanic? I have a shop and the tools to do it but I hesitate to do it because it is so extensive. What do you think? Keep up the good work!

[@MeanBee392]

You are very welcome and hopefully it will be helpful for you in the future! I think that it is a great idea to do a project like this with your son's for the bonding, experience and the memories that will be made lasting a life time. Having basic mechanic skills and a shop with tools this project would be very doable for you. I know it seems like a big project and can be a bit nerve racking thinking of doing it but once you start and get it finished you will be surprised how easy it ended up being. I think you would have no problem doing it and it will save you money, make memories along the way, and give you a huge sense of accomplishment. Use these video as a reference and feel free to ask me any questions and I will do my best to help you out. Hopefully that all makes sense and thanks for watching and commenting buddy! 🐝

[@CentralOregonFishing]

Any tips on removing the lover valve cover bolts on the drivers side bottom closest to the firewall? I'm finding this is an area that has been glossed over, yet the most important part of getting the injectors completed. Thank you for the great video.

[@MeanBee392]

Those can be very tough to get with the limited access. I found using a ball head allen socket along with a universal joint and some extension come in very handy for them. Hopefully that helps and will aid in getting them out. You’re welcome and I am glad to hear that you like the video. Thanks!

[@CentralOregonFishing]

@@MeanBee392 Update: I started on the drivers side, which I realize now is the most difficult to get the valve covers off....but I did get them both off. If I have any advice for the next guys it would be this, "Be Patient" and don't muscle your way through the valve cover removal. I am happy to be looking at 4 new injectors installed in the drivers side and already have the covers loose on the passenger side in a fraction of the time!👍

[@evanch123456]

Awesome video. I have no hazing or making of oil. I'm experiencing long cranks times and tough cold and hot starts. What are your thoughts?

[@MeanBee392]

Thanks and glad you enjoyed the video! That could be a number of problems but I would say the main cause is it is not building the proper fuel pressure. I am not for sure without more info on the pickup what it might be. How many miles are on it? Thanks for watching and commenting!

[@jorgequi6235]

Hi, thank you for your video, I'm thinking right now just that, what did I get myself into, I'm doing the project well, I started to put the passenger side back , but I did not take a picture of all the connectors around the fuel filter, wasted sometime trying to figure that out, if you could take a picture of that are, all sensors on top if fuel filter and post it please. Thank you

[@MeanBee392]

Sorry for the late reply. Are you still needing a picture of the fuel filter head. Hopefully my video series will help you out. 🐝

[@TimsWorkshopTJY]

Setting the valves on this is something you recommend while it's apart even though nothing was removed on the rocker assembly? Just wondering. Thanks

[@MeanBee392]

Just because you would have to remove and replace or pay to have the injector lines cleaned to get back to the valves so it is a lot easier at this point to adjust them. Great question and thanks for watching and commenting! 🐝

[@TimsWorkshopTJY]

That actually brings up another question? When going into changing the injectors the kit has the lower cover gasket the fuel line clips and orings and seal washers for the injectors. The kit doesn't include the 4 per side fuel pipes? When you say cleaning the fuel lines you mean all the lines you removed and what did you clean them with?

[@MeanBee392]

No it does not contain the 8 high pressure lines or the 2 return lines. The only lines that you would have to clean would be the 8 high pressure lines because that needs to be clean fuel before entering the injectors. If you are going to clean them the best way is to have them sonic cleaned bu a machine. Hopefully that makes since and if you have any more questions I will do my best to answer them for you.

[@moakland9756]

I just replaced my injectors in my lb7 and man it was a real pain because whoever was in there before me just about over torqued every bolt. But once it was all apart it wasn't that bad. Now my truck runs better than it ever has and no more smoke, surging idle, or diesel in the oil. Did you have a hard time getting the two bolts on the back side of the valve cover on the driver side? I ended up using a ratchet with a universal joint to break them loose.

[@MeanBee392]

That's awesome to hear that you also changer your injectors your self! Man that's a bummer that all the bolts all so tight. I had the opposite problem and over half of mine were hand tight at very best and a dealer was in mine before I was and that makes me wonder how good of a job they did... That's awesome to hear that yours is also running great. Those back bolt on the drivers side were put there by the devil him self lol! They were a real pain but I did the same thing as you did and used a universal joint to get the too. Thanks for watching and commenting! Cheers to changing our injectors our self's!

[@shaegydog]

Thanks so much for this awesome video!! I have 3 & 8 that the injector will not come out. I have wiggled and pulled and tapped side to side with hammer and won't come out. I have wd40d them and turned the motor over on harmonic with 36mm socket. What do I do to get them out. Help!!

[@MeanBee392]

You are very welcome and glad you enjoyed the video! They are probably stuck in the cup and will pull the cup with them I would just say use the fuel line as a handle and keep working them side to side and they will come out but it can be tough.

[@shaegydog]

@@MeanBee392 yup they did finally come out with lots of elbow grease. And unfortunately they lifted the cups out some. It ended up being all good as I bought an injector cup removal tool and pulled all the cups and reloctited. The tool made it so easy that I couldn't afford not to do and risk having a leak.the truck turned out great and runs awesome. I got some smoke yet but hoping it will go away soon as the muffler burns all old excess fuel out. Otherwise I will have Lincoln Diesel in WI help me out as they are great. Love their SAC45 injectors that I installed and their Service. Again I can't Thank You enough for your video as you got me thru this job. YouDaMan😃. I'm actually going to look to see if you have any videos on turbo or injection pump removal just in case I have to do someday. Heck gonna see if yah have a head gasket one too.

[@nickrobb7719]

How did you manage to get to the back bolt on driver side lower valve cover and the fuel return bolt on the rear cylinder i cant get anything down on them

[@MeanBee392]

It is a very tight spot and hard to get to I used a small universal joint (wobbly) and that made it a lot easier and also going in through the inner fender well. Hopefully this help and if you have any more questions please let me know. Thanks for watching and commenting buddy and good luck!

[@jasonhansen2418]

i got my injectors changed out about 60k miles ago, truck only has 190k on it. started noticing the white haze at idle, realized if i wanted something done right i had to do it myself. i pulled all 8 out and 7 of them look the same but one has a bunch of numbers where the hold down grabs the injector. if those were the stock injectors you took out could you tell me if they had numbers there or not. feeling like the shop i took it too ripped me off. i’d really appreciate your help

[@MeanBee392]

Mine did have numbers on the body of the injector. Hopefully you did not get ripped of by a shop. 60K is really not that meany miles but unfortunately the VOC injector style in the LB7 do not last very long and it seems 60 to 100K is about average. The SAC style is a must in my book because they will last a lot longer. Are you replacing your injectors? If so what ones are you going with? I know if you buy them from Lincoln Diesel Specialties when you send your cores back they will check the injectors and numbers to let you know if they were all changed. They did that for me because I had the same suspicions as you are having with yours. Hopefully this is a bit helpful and if you have any other questions let me know and I will try to help you out buddy! Thanks for watching and commenting!

[@jorgequi6235]

Hi, thank you for the video, I do need help with this please, could anybody take a picture of the fuel filter area, I'm putting the passenger side back together and I did not take a picture of all the sensors and connectors in that area. Thank you.

[@gusmajor3706]

You prolly dont give a shit but if you are stoned like me during the covid times you can stream pretty much all of the new series on instaflixxer. Have been streaming with my girlfriend for the last couple of weeks :)

@Gus Major Yup, I've been using instaflixxer for years myself :D

[@rubenmoreno2257]

Do the wiring harness on the injectors go bad on those HD 2500

[@MeanBee392]

Not that I have heard or experienced but it could be something worth checking out if you are having problems.

[@diesel85idi]

Question. I’m going to be replacing my injectors on my 2002 Lb7 soon. I’m running a super chip programmer flash paq. There is like 4 different power levels. The hottest tune gives just enough fuel to haze black smoke with my stock factory injectors. If I were to put in 30% over or 45% over injectors with my stock cp3 would I pick up any power ? Or is it only worth running larger oversized injectors with a hotter programmer

[@MeanBee392]

That's a great question! On my last set up with stock injectors and Edge tuning it would smoke black a lot and on my new set up it hardly smokes but has a lot more power and runs so much smoother. What I am saying that just because you don't see a lot of black smoke doesn't mean you pickup is int making good power or is set up right when in reality less smoke means it is running more efficient. As for running over sized injectors with your stock CP3 you will pick up power. It always best to have tuning match with your injectors and in the end it's what you are looking for to get out of your pickup. Hopefully this all makes sense and if you have any more questions please feel free to ask. Thanks for watching and commenting!

[@diesel85idi]

MeanBee392 So after further research I’ve realized I need to run 45% sac style injectors because of numerous reasons vs a VCO style. I just want to make sure that they will be fine with a stock CP3 and super chip programmer

[@MeanBee392]

That's very true and that's why I went with the SAC style they are just a much better option. They will work fine with the stock CP3 and the programming. LDS also offers a stock size SAC style now I believe but I would recommend calling them because they are very helpfully and will be able to guide you in the right direction. Ask to speak with Brent or Bob and tell them you saw my video and sent you, they are a great group of people!

[@diesel85idi]

MeanBee392 Fantastic. Will do !

[@Steve_I]

I know this is old, but you can run stock tune with 45s to get you by, But it is best to get your truck tuned for them. Don't risk running a hotter tune meant for stock Injectors on bigger injectors. You will over fuel and potentionally destroy a piston.

[@robertibarra1920]

Should I replace my cups or no first time doing this so I really don't know

[@MeanBee392]

I wouldn't think you would need to replace the cups but if one pulls out on the injector I would just reuse and reseal that cup or cup's. Hopefully that helps.

[@jorgeespinoza8842]

When replacing the injectors do you have to reprogram it so injectors work correctly??

[@californiacctoilets7280]

Lbz and up you have to but lb7 and lly it’s fine

[@samlaine3315]

How did you get the lower of the two fuel lines disconnected?

[@MeanBee392]

That one is a pain but I just used the same quick disconnect tool and had to fiddle with it for a bit. Hopefully that is helpful and thanks for watching and commenting!

[@samlaine3315]

@@MeanBee392 yeah are your lines two different sizes because my tool only fits in the upper hose which is smaller diameter

[@MeanBee392]

Sorry I worded badly. So I used the same style but a different size because you are correct and they are two different sizes. That lover one was a huge pain though and you can always use some kind of penetrating oil in it to also help loosen it up. Hopefully that is helpful for you.

[@dennisdapp7405]

I took off 2 yellow wires off an injector does it matter which goes where I forgot to mark them

[@MeanBee392]

Sorry for the late reply but did you figure it out?

[@dennisdapp7405]

Yes I done a continuity test on the other side worked out well thanks for the reply though enjoyed your video

[@daveho4244]

thanks so much for this. All I ever see is 'just do this, that, and the other thing' but not really show/explain what the hell they are doing. My 01 LB7 just threw a code for the injector sensor. (#2) I have 300k miles and have had the injectors replaced 4 times. I'm at the crossroad. Do this job, and replace the injectors, or just the sensor? What do you think? Is it worth doing it twice? Or just once and tossing injectors that are still good? Or just do the sensors? (Driver's side only.) I subscribed and thanks again for the great video! I know in the long run, it's up to me and me alone, but I'd like an opinion from someone who has done the job.

[@MeanBee392]

You are very welcome and I am really glad to hear that you found this video helpful and informative! That is a tough question to answer because it really depends on where you are sitting financially. If doing the full set is going to strap you for money then I would just do the sensor and then start saving up. If you are in the position to be able to afford the injectors then I would highly recommend that and would only recommend doing the SAC style then you will no longer have the stock LB7 injector problems. Hopefully that helps out a bit and thank you so much for your support subscribing, watching and commenting I really appreciate it! 🐝

[@daveho4244]

@@MeanBee392 Thanks again. I'm in the job now, and decided on just the sensors. (Both on the driver's side.) Having a b*tch of a time with the fuel lines! One I got, the other is currently eating my lunch. I just keep thinking if you can do it, so can I!

I have a GMC 2500 2002 6.6 duramax diesel in engine oil

[@MeanBee392]

I would bet it would be the seals on your injector return line under the valve covers.

[@theodorecarbajal2975]

Whoa my 7.3 injectors are alot easier lol I was curious how difficult the dmax were, still a awesome motor

[@MeanBee392]

Haha yes they are. The 2004.5 and up Duramax are a lot easier because you don't have to pull the valve covers on them but unfortunately mine is not like that lol.

Yes this is and LB7 and no you do not have to pull the heads to replace the injectors.
