- Опубликовано: 25 авг 2024
- This video is part 1, will cover a DD15 major overhaul, the engine block has been properly machined by the guys over at Engine Saver Reboring in Chino, California.
I am going to break these videos down into parts, I will explain everything as clear as possible.
This video includes main bearing installation, main bearing preparation and new crankshaft installation. Part 2 will go over how to torque the main bearings correctly and the torque specifications.
I will also go over what tools are needed in order to complete the job properly.

I love these kinds of videos very educational👌🏼👍🏼 Looking forward to part two
How much is an over haul like that cost ?
I can’t wait to start working on these engines you inspire me thanks bro
Thanks for the compliment.
Good job but always check the machine shops work by placing the crankshaft in dry with plaster gauge and check your clearances then pull it back out and lube it. End play is also very important.👍
Appreciate the advice.
I was always told that lubing the threads can affect the torque due to less friction than what would have been tested when the torque specifications were originally decided.
That I am not sure of, if I am not mistaken, the book or service manual I have says to lube just the threads and not to dip the bolts into oil. Probably for the reason you mentioned. But I’ll double check the service manual when I get back. I would hate to give the wrong information.
The Cascadia workshop manual at the beginning of it does mention that the torque specs are for lubed threads, but it should only be 1-2 drops of oil.
Awesome video full of knowledge very much appreciated just need to turn that music down just a little bit and you'll be right on spot😁
Great video! Can't wait for part 2
Great video. Need more mechanics like you to keep the country moving 🎯👍👌
Very important that you clean your parts
Love your videos good work 🙂
You are a rear Gem❤
Thank you
And how much is this full rebuild?
hola que buen video, me encanta la mecánica de truck
Where did you said your training program is???. Lol!! Just kidding. It's a awesome triple A video. Very well clean an organized. Now from driver I wanna become a tech.lol. it's and inspiring video .
Hi is this engine same with new generation MB Actros's engine?
Thank u Pedro for the amazing video … WS Carriers Llc
what did the full rebuild cost when you were done...line boaring eh..good job..i heard the bearing failures are high on the rebuilds but then i found out some of the bearing sets are not mached from the same company...and of course nobody ever take the time to line bore it...I bet your engine will last a million smiles..
You are looking at around $35K with labor
Using original parts from Detroit, being able to use the same crankshaft and a few other components will save money.
@@CarlosDieselElectric wow thats super expensive ...i wish we were back in the old days..35k eh...thanks for letting me know..
Woww que hermoso video . Que linda es la.mecanica 😍😍
No platigauge to check first. Is it something were you've had the experience these parts are always on point or do you have a tip/trick that helps you know it's good?
The engine block just came back from the machine shop. They line bore, check the liner protrusion and cut for bushings if needed. They also checked and polished the crankshaft. I trust their work.
But it doesn’t hurt to use a gauge. In my experience the parts have been on point.
hello may I know Which Crankshaft Assembly is needed to overhaul detroit diesel engine 16v92 81627400?
(I assume one of the RH Rotations…but which one?)
1. 16V-REAR (RH. ROTATION)
2. 16V-FRONT
3. 16V-REAR
4. 16V-FRONT (R.H. ROTATION)
Next one please
Quick question, can you replace rod bearings without taking piston off?
Once you remove the oil pan and oil pump. You can rotate the engine to the desired piston (connecting rod) you want to work on. Remove the cap and replace the bearing. Remove the cap, push the connecting rod upwards. Slide the bearing out. Install the new upper bearing (add lube). Install the lower connecting rod cap with the bearing (add lube) the same way it was removed (very important). The cap is specific and must be installed the same way it was removed. Look at the side, you will see numbers. Torque to spec, this is most critical. Once you are done. Rotate the engine to make sure there is no binding and proceed from there.
Chino ca? I might be heading your way my friend.

Hi Pedro I liked what I see, it looks like you know what you’re doing, one question, how much are we talking about doing this to my truck I got water in the oil and I want to know how much it would cost me to do this to my truck.
You would have to pressurize the coolant and see which liner or liners are leaking coolant.
This requires draining the oil, removing the oil pan so when the system is pressurized you can hopefully see which one is bad.
What year is the truck?
Can you train me how to rebuilt the engine
Para ke cresa sus vistas vale la pena

Hi Carlos! How much the repair invoice is going to cost? total w/tax. thanks!
D K I’ll do a final video and include the cost.
Pedro saludos, cual es el misterio que no debes tocar los metales con los dedos pelones. Sácame la duda.gracias.
Los metales deben de estar lo más limpio posible. Se tiene que evitar tierra, polvo or cualquier cosa que puede contaminar o obstruir entre el metal y el cigüeñal.
@@CarlosDieselElectric gracias pedro,me decían que dejar la huella de los dedos es malo, suerte pedro.
Are you using new bolts on the main caps? I've heard that if they need to be tightened to a certain degree, you should use new bolts because they stretch?
The main bolts can be used again, however you can measure them and see if they fall within limits. If not replace them. They are relatively cheap.
Thanks for these videos they very helpful!! I want to rebuild my dd13 engine, but I see you have a repair manual. Where can I get a repair manual ??
Valley Power Systems in City of Industry, Ca. Ask for Steve or Nick.
The book is definitely worth having.
Yes !! Thanks for your videos !! And your feedback
By lubricate what do you mean ? Would I just go to a shop and ask them to lubricate my engine? And how long should a oem overhaul last?
All good questions, when you lubricate, you install main bearings or rod bearings with some kind of assembly lube. There are many to choose from. Are you planning to change your main or rod bearings? Are you talking about an engine inframe or overhaul (rebuild).
An over haul should last the same as a new engine depending on maintenance and other factors. Engines are expected to last 1,000,000 miles.
Are the main and rods a 1 only time use, do you measurr them ??
You can remove and reinstall them if your inspecting and they are within spec. But I recommend replacing them once they are removed. They are a one and done.
My engine has a cracked liner
With 700 thousands miles
What all would you recommend getting rebuilt.
At 700K miles, I would recommend you consider a rebuild. If you just consider replacing the 1 liner, you have to ask yourself what are the conditions of other liners? Are you going to pull the others out for inspection? Then you are going to pay labor on all that.
Try pricing out the cost for just the one liner, parts and labor.
Then try pricing out the cost for the rest of the liners. See what the difference will be.
Mine was just rebuilt, when they started it said at idle sounded fine, when they gave it some fuel it made a squealing/squeaky sound?? They found #1 upper/lower bearing scored replaced it tried again same noise- tearing it back down tomorrow ~ ideas??
Prime the oil system correctly, try pushing about 3 gallons of motor oil. That oil is addition to the 10 gallons you are adding. Also, the oil filter, soak it with motor oil before installing.
Check to make sure you are torquing the bearings correctly and evenly. So do a little on the left then to the right and so on.
Use assembly lube to help. Once you are done, rotate the engine a few times.
This will help to make sure it rotates freely without any binding or catching.
Had the same issue my injector was seated improperly
What is the ball park cost to rebuild the dd15 ?
To completely tear it down to the block, have all the machine work done, parts (inframe kit, cylinder head and injectors) then add labor. You are looking at around $35K to $40K
If you add the crankshaft, turbo and fuel pump then the cost will increase $7K
These things get ridiculously expensive.
Hey ,how’s it going What website can a crankshaft kit that come with all the bearings ???
I purchase my stuff from Freightliner or from Valley Power System in City of Industry.
That is your best bet especially with all the parts supply issues going on.
where you put you main bearing installation ??
Look for Part 2, that will show you how to torque the main bearings.
Did u reuse bolts for mains ? And do u reuse bolts for rods ?
I reuse the main bolts as long as they measure within specs. The main bolts are pretty strong and can last
The rod bolts are new, they come with new connecting rods. When I do a rebuild or inframe, I always use new connecting rods.
If you're going to all this trouble, and the customer is going thru all the expense, you might as well do it the best way you know how.
I was wanting to know can you convert a dd15 to 18 speed auto
I don’t see why you can’t, it would require MCM programming and a harness. So that would mean access to schematics.
The engine will do the job no matter if you have manual transmission or automatic.
@@CarlosDieselElectric I always was wanting to know on how much an Inframe cost
I’m wondering how much they can rebuild my 2015 DD15 for me I have a little over 700.000 on it now but still running ok but I don’t want to wait till it starts problem before I do something
You should be able to get about 1,000,000 miles on your DD15 as long as you do your proper maintenance.
I am going to do a video on the cost of an inframe.
@@CarlosDieselElectric ok thank you for quick reply
And where are you guys located if I may ask
@@MegaSamco we are in Montebello, Ca 90640.
@@CarlosDieselElectric hi Pedro what is your adress? I am in LA As well
@@willmalloy4940 our address is 659 S Maple ave. Montebello, Ca 90640
Carlos how do I know if I need a rebuild or Inframe I have 2015 cascadia with 700k mikes plus no issues just finished paying it off
I think you are in great shape, the only thing that comes to mind would be the to service the oil suction module and the o-rings on the tubes and just make sure to stay on top of your oil changes and you should easily hit 1 million miles.
I have a few customer that have 1.1, 1.2 million miles on an original engine and still going, so it is possible.
Carlos Diesel Electric ok thanks for the fast response. For the oil module and o rings do I go to a freightliner or my own personal diesel mechanic
TroyP20 if you have a mechanic that can do the work correctly then you should be fine. Freightliner will definitely charge more for labor.
How much cost dd13 overhaul 2023?
What year is the engine? Is it a 2023?
@@CarlosDieselElectric dd13 2015 is 570k miles is blow by oil cap and oil stick
@@miguel57729 do a compression test and see what cylinder is weak. You can do a valve adjustment and see if that helps. Also, check the crankcase filter assembly
@@CarlosDieselElectric Thanks for the recommendations. I'll start with the crankcase breather
Why do they say these are impossible to rebuild ?
I don't want to throw shade on anyone, but I'm guessing there is something being done wrong in the process. Not sure if the issues is with the assembly, oil priming before starting or fuel priming before starting.
Yeah I got one and checking forums people saying hard there throw away engines and the bottom end is bad . I got 880k miles on mine so trying find someone who can rebuild when time come
@@TheKidlyfe recommend to stay on top of maintenance. Replace the oil suction module along with the orings and your engine should last over 1 million miles east.
Should I do mains and rods when I get that done as well ?
@@CarlosDieselElectricshould you replace and main and rod bearings before a full rebuild? Like at around 500k miles?
Can this be done while in frame?
The main bearings yes, they can be replaced inframe. The crankshaft, I don’t see how it can me done.
If the crankshaft seized, then you have to tear it down and have the block line bored so it can be true and straight.
@@CarlosDieselElectric sorry dumb question. But if you crankshaft seized the truck won’t run correct?
camshaft-cam-pump oil và pump air timing of this
What is the cost of having the block inspection?
Chad Souders I know cost for the work done is about $2000-2500. I would recommend to call Engine Saver Reboring in Chino, Ca. Dan and Justin are very good at what they do.
@@CarlosDieselElectric Were are you Located ?
Too bad you didn't convert it to a DD16-crankshaft and pistons are all that's different. (same con rods).
Explain more please
@@zeekfranco509 Only difference between a DD15 and DD16 is the piston stroke. They do this by having a different piston (wrist pin is higher) and crankshaft. Otherwise it is the same engine. Course the DD16 still uses the gear driven turbo compounder.
@@Tchristman100 thanks for the reply and extra info I’m going to dive more on this I’ve rebuilt my first dd15 but didn’t know I can step up the game like that
How much does something like that run?
A typical inframe is less than the overhaul/rebuild I am doing. Are you asking about labor or parts and labor?
@@CarlosDieselElectric yes, I got some quotes from the dealership, and im comparing prices. If you don't mind I'd like to get the quotes for both.
Do a 3406e😅😅😅
What Mileage would you do this at??
Main bearing replacement is typically done at around 750K miles.
The video is because the engine seized due to oil pump/pressure failure.
@@CarlosDieselElectric I live in Sun Valley. I just got a DD15 570k miles. Whats your Shops Hourly rate?
@@willmalloy4940 we charge $85 an hour.
At 570k, recommend to have the valves adjusted unless they were recently done.
Hello sir, good evening, Hana Asma: Sami Marei, an Arab national, age 38, I work in the field of diesel truck repair, and I have more than twenty years of experience & is it possible to go to work with you in the same field? Can you help me to send a work visa from your side in order to work with you? Thank you, sir, please reply to me my message
Dumb desighn on the thrust bearing. Shpuld just made like gas engine bearing.
I know this video is old but why is everyone so scared of rebuilding DD15s? even with a spun bearing if a reputable shop machines the block and you get a new crank there's no reason why you cant rebuild one and last a long time
Knock on wood. I haven’t had any issues with mine. I recommend taking it to a reputable shop that follows the book to the T.
The DD engine is solid. The bearings spinning could be an installation error or other factors that contribute to it failing.
@@CarlosDieselElectric yes now that you mention it, thats a shop manual? Im not located in the US so I cant go to California to look for it but Ive seen a bunch of "shop manuals" and stuff online, but I just dont know wich one would be good for rebuilding one of this it would be helpful though since I have a couple of DD15s in my fleet right now
It's not a real video unless you have a money shot.
