Videos like this is why I like the RU-vid format better than the Cable TV show. You have the time to explain what is wrong with what you're seeing and what needs to be done to correct it. I particularly liked the explanation of what was wrong with the way the cylinder was honed and why it is important to have it done at the correct angle.
I recommend putting a gm alternator for a duramax on it I did that on my 12 valve cummins swapped 05 chevy 2500hd the dodge pulley will bolt right on to the duramax alternator then its all internally regulated and you can mod the factory upper mount just needs widened and then make a custom lower mount just my 2 cents
The steering box is mounted in single sheer even after you repair the rail and fit crush tubes. Double sheer is when support is provided on both sides of the mounted component and the fastener passes through all 3. Cross hatch angle determines piston ring rotation speed. The depth of the cross hatch determines how much oil is held on the cylinder wall and the angle will affect oil retention duration. Oil and hone finish are the secret sauce of efficiency which is where performance comes from.
Also, there's a reason that you don't see a lot of vertical or cross welds on factory frames. It's called cyclic stress. Look it up. Round holes with rivets create way fewer stress risers.
I'm no machinist, or welder, but I saw those welds and lack of cross hatching from a mile away! Good to see the owner took that baby to the right doctors!
Teacher in High School had one of those little motivational posters up on the wall that I still remember (was in the mid 80's) to this day, "If you can't find the time to do it right, when are you going to find the time to do it over?" I have used that countless times in my life, especially raising kiddos.... Love you content!!
Please DO continue talking! My favorite part of any given day is when a new Professor Holden video drops and gives us bits of wonderful technical knowledge! I can listen y’all do this all day! Wonderful explanation of the frame and shear strength, and also the crosshatching of the cylinder wall! Thank you! Love this channel!
As a casual, non tech, viewer, I've never known really why the cross hatching was significant when mentioned in videos by other car RU-viders. Thanks for explaining that... now i get it
Buy cheap get expensive, having to fix others mistakes is more costly on time and resources. Undo before you can redo. Glad you back making full videos here
"He wouldn't say what shop did this" AKA "he did it himself" Edit: If someone really did this to this guys truck, he needs to sue the shit out of them.
That's my dream truck, even has the rear doors i want but i cant picture ever "needing" it so ill just appreciate others with my same taste for vehicles
They never cleaned or shaved the block. Then put it back together. Wow that cylinder wall like that would have blow by. The cross hatch on the cylinder wall is very important. Even on small engines.
Thanks for the "what not to do" lesson. I'm about to start a diesel swap into a 1990 f150 out of a hino and I'm hoping I don't make too many problems for myself.
@@hostflies7183 I'm not equipped for the recording. All I have is an old smartphone with a scratches lense and not a lot of memory. I might consider it if I find a camera that'll do the trick for cheap. Then there's tha matter of the editing...which I niether have the computer nor experience to do. Though I could likely learn the editing by trial and error.
@@hostflies7183 w04ct, keeping the 5 speed that's on it, backed up by an np203 divorced transfer case. For now I'm going to stuck with the stock 1/2 ton axles, but I have a set of 3/4 ton if necessary.
Awesome build/re-build! Been recently looking at barn door burbs. Did come across a stock 6.2 3/4ton local to me. Just wish I had the cash because it just needed glow plugs and price was right, but Sold within a week.
Lots of people conflate pretty weld with good weld. I would take a proper burned in 7018 over a pretty mig weld every day of the week. Unless its dual shield flux core.
I wasn’t ready for the video to end. Don’t know where you guys are based but I wouldn’t mind having you work on a 2nd gen Cummins nv5600 build I have. Top notch work.
If your running a factory trans mount then why run the bushings on the cross member also? Wouldnt you want to use the cross member to help stiffen the frame some?
the biggest thing I ever learned building anything from model cars as a kid to semi truck repairs, you need to come to terms with what you don't know and understand you can't learn it over night and then compete with guys who have done it day in and day out for the last what ever years. You just need to know what you don't know and go educate yourself before you touch it. It aint easy to admit you don't know everything to most people. but its the truth to many.
The only real issue I saw aside from cosmetics was the front crossmember clearance. Maybe the guy thought it was getting lifted? Nothing wrong with the belt drive components, but I'm coming from an industrial background. That frame will be fine, not a ton of stress up there, not sure why he chopped the frame though. Your rebuild is an improvement. Looks like the original builder didn't have access to proper tooling. Like a plasma cutter
Oh man, I doubt they moved that dingleball at all when they jammed it in the cylinders. Just jam it in, let it spin, YEP THAT'S GOOD. I feel like they just did a 10 thou deck, new headgasket, and a coat of paint and called it "rebuilt"
Im only 6:42 into this video and just looking at the frame man hours to fix everything vs finding another rolling chassis to start fresh on would be the most cost effective part of this fix in my opinion.
8:24 into it. You should have got another frame. Trusting even ground down welds and knowing the gap fills the previous shop did would always be in the back of my mind
Looking forward to part 2. Looks like the motor needs a complete rebuild now that they messed with the cylinder walls. Who knows what else youll find. You should deck it while your at it to match the head. Cheers
What is your solution to run the stock Dodge AC pump & alt brackets & placement since the chevy frame is 4in narrower? Was that why they notched the top on the passenger side (stairstep)? Where did you get a non pinch style Pitman arm that's splined correctly to shift it 90 degrees? We always swapped out the box for a 2wd style. Thanks D
I would get another frame and put this out as a "how not to build a safe frame". Every time I take an engine apart I flush all oil and cooling channels in the block and top. It looks lile he used a ordinary honing tool with 3 stones.
Not to Bash Holden Bros ...... But maybe instead just being somewhat rude, you guys could give a little instruction to the person who did the work? Not everyone starts out as a badass fabricator. We all have lessons to learn. It does look like the original builder put a decent amount of time and energy into it. I love the vids and am excited to see your new show.
They weren’t rude, they didn’t name the person that did the work. All they did is point out a bunch of things that were wrong, and as far as the original builder putting a lot of energy into the build if the work is subpar it doesn’t matter how much effort was put into it, it’s still wrong.
I am not a certified welder, but even my first welds on my own were far better. I am also not a certified mechanic, and I knew as a young adult about cross hatching, which was not before the internet. I learned a lot for all those old Hot Rod magazines decades ago.
It would be better to just go buy either a factory Diesel chassis ,or a custom chassis than pay to redo all of than over again..I sure wouldn’t waste money on it twice..then drop a dodge motor in..
