DEBOSS GARAGE make sure you cover custom fuel economy builds and what transmissions can be used in engine swaps... Can you still use Chevy pre-Duramax/Allison transmissions from the old 6.5L Detroit for a 5.9? And vise-versa?
I have a 5.9 24v in an 06 3500. Driving home to GA from NC, it developed a knock (noticeable at interstate speed). Immediately pulled over and had it towed to the nearest Walmart. After looking at what I could (it was around midnight, so very dark), I decided that I would just get it to the nearest Dodge Dealership (1/4 mile away), drive home, call them in the morning and have them diagnose / fix it. By the time I drove the truck out of the parking lot, it started thrashing (badly) and died. It would crank, but would thrash the motor / cab badly, so I turned it off and had it towed that 1/4 mile to the dealership.
Tech cranked it, turned it off, said the bottom end was out and wanted to charge me $10,000 to $15,000 to put a "new" (rebuilt) Jasper engine into it. I believe - firmly - that an injector failed, chewed a valve seat, and it is - in fact - the top end that is out. I'll know shortly because ....
I struggled for a week on what to do. After googling and watching videos (specifically, this one), I decided to tow it home and pull / rebuild it myself.
Shop crane arrived 2 weeks ago and the engine stand came in last week. While I haven't had time to get it out just yet, this video series has given me the confidence to attempt the work. I intend to reference the *&^% out of this series (along with other, similar videos).
Thank you. Thank you, so much.
I intend to video the work and upload to Youtube during the process. I just wanted you to know how much I appreciate your videos. I am not a mechanic, I learn as I go, and people like you make all the difference.
Did i miss the piston coolers
They are plastic should be replaced when ever the crank is out
After torquing the rods shake them on the crank if something is wrong you wont feel the rod move that step saved an engine someone else took apart which the mechanic used a punch to get the piston past carbon ring which put a minor ding on the rod so when the rod cap bolts torqued it pinched the crank
All ways shake your rods
As far as assembly line, I am in absolutely no way condoning this duckerie but here is something I seen(do not try.... Absolutely any of the following) my neighbor had a 80 c30 flatbed he used for hay... He didn't have a v8 to go in it so he put a 4.3 on the old bulldog tyranny, sure enough spun a rod bearing, thanksgiving night he dropped the pan, undid the 1 rod that spun, changed that 1 bearing only nothing else, and used personal lube (KY) on it and called it done... I couldn't believe I watched/helped with this foolery and still can't believe he still runs hay out in the field in the mornings with it
I hate working on cars period,i guess cause i drove piles as a young man and had alot of bad experiences workin on em,and this was when u could change a fuel pump in 5 mins.i have a 12 v and wondered how much it cost to have it overhauled,which led me to these video.iv become addicted to em now.very well done.i could sit and watch him work on the cummin all day,as long as i dont get greezy.ha ha
Does my crows foot count as"getting the torque wrench in there? hahaha great vids man, love the detailed mechanical explanations in these videos, love the straightforward no BS approach to every job, and for god's sake I LOVE 18FT LBS!!!!!!!!!!!
Great video really like your channel. I am definitely a Cummins guy. I have had my mechanic shop for 25 years this year. Not saying it's wrong but I never pull the head removing or replacing the engine. Take radiator and condenser out side it in. It's wild seeing how different people do same thing different ways again really like your channel thank you and have a blessed day
i just did this to my 24 valve. i spent 1800.00 with full machining, over sized pistons, and such. took me 7 months from start to finish and the machining took about 3 and a half months for the machine shop to finish the block/head. they didnt do any disassembly or reassembly, just machining.
Great vid! I’m new to Diesel engines and this vid really answered a bunch of questions I had. Good work young man. This vid will be saved and watched over and over again. I will be watching your other vids as well.
Where the hell are all of these engines? Been around decades in cabs that are just itching to rot away, yet sill haven't seen a single unit in the wreckers that I regularly go, nor a Kijiji part out ad within 500 miles.
Dream project (well .. perhaps aside a diesel/nitrous hybrid rocket on the back of a coke bottle mopar, lol) is to stuff a 5.9 into a '69 or '70 Kingswood or something similar - stylin' service wagon that I could still afford to drive at $5/gal.
Great vid though.
I don't want to hear anymore comments about about Chinese shit ,they are as capable as anybody else as far as quality is concerned ,all the top quality manufacturers are using them as can be seen by this vid .On the other hand if you want cheap ,shit they will oblige ,and nobody can touch them on price .And the good old US of A queue' s up for it ,then moans when it let's them down .
The retainers look like the old retainer has a flat I dont know counter sink at the bottom of the taper and looks like new retainers are just a taper with no flat on the bottom of taper.
. I thought I seen it first time had to rewind couple times to confirm.
Hey man absolutely love the show just started watching it recently. One thing im finding ridiculously funny is how many ford commercials there are with your apparent love for recent models lol. Youtube ad win/fail right there lol
6.4 HEMI! I have a 2003 Ram 2500 with the 5.7l hemi and I tow 8k+ behind it at least once every few months. Does good, maintains above the speed limit all the time and averages 8mpg while towing that. I like it, does what I need it to do.
If you really want to torque everything get a motion pro 08-0380. I use mine frequently for tight spots, I've even put a ratchet in it before. Good for up to 100 ftlb I believe. Just make sure to use it at a 90* angle to the torque wrench so you don't have to do all kinds of complicated math to recalculate the torque.
I love re building.. Never get to do much of it anymore. I think it is great that you are picky. As for torqing the turbo bolts. If you take a stubby box wrench with a 3/8 extension square in it you can do it backwards. I didn't have one so I made one. It wasn't pretty but it worked for me. I had a super picky client over my shoulder other wise I would have just wrenched it.
