Poor Bruce. Thanks for showing us scene 16 of The Battle of the Injectors. I'm glad I'm not a diesel tune-up mechanic. You know, a carbide recip blade would make short work of that brace, and you have a capable welder to put it back together... Otherwise, Curtis' suggestion to holesaw it would be less aggressive. Good luck, man.

Don’t worry, Scene 17 is coming 🤣. I did think about a) cutting and re-welding or b) cutting and bolting it back in (you know, for next time). Really makes no sense the way they have built it - seems like they were intending for a removable section.

Good luck with that, I’ve have injectors stuck soo bad they ended up being snapped off enough to remove the head and the whole head was just replaced. There is a tool that actually extracts the injector in sections. Dark clouds descend if that #4 injector has to be removed. Unless it’s a crew cab or the plastic cover on the engine is present. Water builds up in the injector hole and locks it rusted tight

@BruceandKrista Ай бұрын

Well for now I’m hoping it doesn’t need to come out! If it really comes down to it, I have a spare engine with all the injectors out, so a head swap is possible, though it wouldn’t be fun. Plastic cover was present, but I don’t think it was enough unfortunately. Not the best design.

I'd be tempted to take a hole saw to that bracket. Then, after you've got the fixed & motor running, weld the plug back in. I was hoping you had that issue figured out by now! Hang in there.

@dathat555 3 ай бұрын

Good idea. That would allow using a threaded rod aligned straight over the injector and a nut and washer against the bracket as a puller, as an alternative to the pneumatic puller. The drilled hole could be as small as the threaded rod. A larger hole is needed only if the injector has to come out through the bracket (or so it appears from a few thousand miles away).

@@dathat555 I do not know what that bracket supports but maybe you would not need to even weld the plug back in .

@steveogilvie5203 It's the back of the cab support. I don't know Fuso's very well, but I am very fluent in Isuzus. And that's what they are for on them. Heck, I'd be tempted to drill a hole in it, then weld a flush tube in the hole to reinforce it, and leave the hole for the "next time."

@BruceandKrista 3 ай бұрын

Great ideas! I was also thinking of making a puller that uses threaded rod and an upside down U that goes down each side of the injector to rest on top of the engine. My main concern is how hard can I actually pull on this thing before I rip it in half….

@BruceandKrista looks like you're going to find out! I'd come over and help, but I'm too far away. I'm about to install my new high output injectors in my cummins.

The cross brace is pretty easy to remove. I removed/replaced mine to get at a stuck glow plug. Other than breaking and retreading a couple of wheel liner bracket bolts I would say it is 1.0 to 1.5 hour job.

@BruceandKrista 3 ай бұрын

Good to know - I’m sure all of my liner bolts would break 🤣. If I can’t get around it any other way that’s the direction I’ll go.

@1aquaholic 3 ай бұрын

Actually you could use a long bearing puller also where the arms would grip the injector and the threaded portion would push against the frame support.

@BruceandKrista 3 ай бұрын

Yep, would need to be inside out, as the bearing puller uses a fixed center pushing inward and the arms pull away…. I would need the center to grip the injector to pull and the arms to rest on the support.

Another great video, thanks for sharing! I know this question comes a little late, as you have already removed 3 injectors. Did you measure the return flow rate of the injectors before? I got the suggestion to check the Return Flow rate of each Injektoren, to find out if and which injector is defect. Maybe you are lucky and only the pump is damaged.

@BruceandKrista 3 ай бұрын

I didn’t - but based on how things failed (ran fine one day, and not the next) I suspect that the injectors are fine. I didn’t get any injector related codes from the ECU.

@mattimatt4734 3 ай бұрын

@@BruceandKristaBut why do you remove the injectors, if you expect that they are fine? Would it not be enough to clean the rail an the line to the injectors and the rail?

@BruceandKrista 3 ай бұрын

Sure, as long as nothing went into the injectors. I don’t know if anything did. I suspect not, but if they had been easy to remove, it’s easy to have them flow tested to be sure.

@bobmckenzie386 3 ай бұрын

Wouldn't the engine run (rough) if 1 injector was not working? Did you have any fuel coming out of the injector pump before you connected all the lines? Keep at it you'll get it.

@BruceandKrista 3 ай бұрын

Yeah, and if there is an injector issue it should throw an injector code at me, which it hasn’t. Have yet to re-assemble everything and give it a go - which may be the way to go!

@1aquaholic 3 ай бұрын

Had a similar problem with my Fuso right under the support mine's a bit older than 05 so I don't know what your injectors look like but mine had two ears for the bolts to go through I was able to thread some spectra line through the two ears up around the brace and then I simply took socket extension and started twisting the lines to tension them that mechanical advantage is pretty extreme and it popped it up.

@BruceandKrista 3 ай бұрын

Cool! I guess I could make a “hook” that threaded on the top of the injector and attach a line there… Great idea!

Hey Bruce have you put $280,000.00 worth of time & materials into it yet? Not to mention wasted time that could of been better spent ADVENTURE TRAVELING! Not digging on you Bruce, you are a master at this stuff. I could never do what you do, nor did I have the time! I am just trying to get some interests on our All Terrain Warrior that is for sale if you know of someone looking PLEASE HELP us sell our rig and send them to our channel for a full video walkthrough. P.S. Asking price is $245,900.00.

I took a few paracetamol to help with your HEADACHE - did you find that the headache settled down? If not I could try some paracetamol in my diesel tank. Just let me know.

@BruceandKrista 3 ай бұрын

I wouldn’t suggest putting it in your diesel tank, you’ll likely end up with bits in your fuel pump, and injectors… then might have to re-watch all my videos again….
