WHAT SEPARATES THIS GUY FROM OTHERS ON YT IS THE FACT THAT HE IS A TRUE MECHANIC NOT A PARTS CHANGER. THIS GUY IS ANALYTICAL AND WOULD HAVE BEEN SUCCESSFUL IN ANY OCCUPATION
@Connor Jamie Don't do it guys, it's a scam.
Well said
Factz
Why you yelling?
@@joselazaro5440 I USE CAPITAL BLOCK LETTERS SO THAT PEASANTS FROM NON-INDUSTRIALIZED NATIONS AND SEMI-LITERATES CAN UNDERSTAND. MY TEACHING EXPERIENCE INDICATES THAT THE IMPOVERISHED AND THOSE WITH COGNITIVE ISSUES ARE MORE LIKELY TO RESPOND TO BLOCK LETTERS. CURIOUSLY, YOU RESPONDED...
This guy understands diesel engines as a system. He understands the INTERACTIONS of all the components of your application. A real mechanic.
Your systematic thinking and doing negative checks is what differentiates a good vs a master mechanic . You never learn this in schools. It's really using your brain and logic
Thank you sir. I'm still learning like everyone else. I just have been around the Cats for awhile now.
Couldn't agree more
and dogs too judging by the outro
No! manufacture training teach you the systematic testing, this guy is simply regurgitating this training.
For techs who have no manufacture training this sounds like magic. LOL
Your videos are a god send! I'm about to graduate from the diesel program at UTI in 2 weeks and I'm just trying to learn all I can. Guys like youself are the ones who will help us new guys to get on our feet. Thank you sir, you are a gentleman and a scholar.
A surprisingly common fix for low power complaints is removing the bunched-up floor mat from underneath the accelerator pedal.
First let me apologize because this is not a comment on this video but due to my lack of computer savvy I'm really not sure of any other way to directly contact adept ape . I have and chasing my tail and absolutely hemorrhaging money on my MXS and after bending over $12,000 and numerous cash shops my truck it is still running as bad if not worse then before. If you read this message and wouldn't mind possibly giving me some insight on what you think problem could possibly be please email me at dbrandoncarroll@gmail.com and I can go over all of the work that has been done so far and the issue the truck continues to have. Once again I apologize for trying to contact you this way but I am in a dire situation and desperately need your help. Thank you
We've had lots of dump trucks with dragging brakes come in, and it's dirt built up under the heel of the brake pedal.
@Evermore 000
Ur right removing fllor mats under pedal make ride ugly. U should try ...
from Algeria in the Afican continent
you sir are amazing
respect
I can watch you all day and not get bored. I have learned a lot from your videos because I’m a motor t mechanic in the Marine Corps and all we work on is C-12 and C-15
Now that i run a c15 nxs 07 model your videos have been a great help in learning this motor so thank and salute for your dedication to help us wanna be gearheads try and figure some of this shit out ourselves...
Loved the Trebuchet troubleshooting analogy great stuff. Excellent video.
Great job sir, very systematic, "MOST" back yard shade tree or half ass mechanics are NOT going to bother with actually checking these items and doing it right. Thanks for taking time to share, God bless
Congrats on 70k subscribers!! Keep up the good work!!
Your videos are gold man thank you
All this low power talk reminds me of some detroit's we had years ago 😑 cat has my heart now 😍
Excellent checkpoints ideas! Thanks
Hey Ape. Super informative and knowledgeable video Thank you. Haven't solved the mystery, (black smoke and powering out in 3306 330bl excavator, only once warm and operating), but feeling much better equipped to figure it out. Great music too!
Had a truck driver complaining of low power on a Detroit Series 60, he was irate and telling me that Series 60s were shit, got into the cab of the truck to put it on the wheel dyno, rubbish all through the cab, a plastic milk carton tied to the gearshift that was full of cigarette butts and the smell of off food. Put the truck on the dyno and did a pull, 62% throttle was the max, checked the throttle pedal, found a chicken bone stuck under the pedal, put on gloves, removed the chicken bone, low power problem solved.
This type of stuff you literally couldn't make up.
He was special. Lots of special people in the trucking world.
Truck drivers suck. Ever get a shifter covered in lube and pubes...i dont deal w drivers anymore
Lol that's to funny :)
thats the greatest thing i have ever " heard" you have made my day, thankyou!
Josh, always learn when watching your videos. My 5 cylinder VW diesel (non turbo) doesn't run so good at tick over when hot. Otherwise it's a beast...a low powered, slow beast but a beast none the less!! To me it's definitely an injector issue but you mentioned a few other possibilites that I wouldn't have thought of. I like the idea of using a temperature gun on the exhaust manifold to look for a dodgy cylinder, will check mine later, can't remember if it has a 'log' exhaust manifold but lets see. Thanks again..
From amritsar punjab india and toronto ontario canada. Amazing videos and technical master.
Excellent, no other word would do. Thank.
Lol! I had a operator come into the shop and said the head is cracked and truck overheating. 3126...... No Water pump belt on it..... Super videos.... Thanks much!
Good refresher course man,, thanks...
great information from a great man many thanks mr.josh
Adept Ape, you are a very smart individual. Thank you for posting these videos!
Love your videos. Helps me out tremendously. Thanks !!
Good information mate Big thumbs up 👍
I worked for Caterpillar, in the 80s.had a 3408 with low power in a dump truck. Searched for a while,long while. Eventually found a dead bird in the aftercooler inlet pipe .someone had work on the truck and not sealed the pipes, so the bird made its nest in the aftercooler blocking partially. The truck was running in a open cast cement mine.
You are a great Mecanic thanks a lot
Thanks I really needed this
Great video! Thanks!
I love mechanical things and explanations on how they work and fail. Since watching the Adept Ape, I finally realized that you sound just like the Norm Macdonald. The only difference is that what you say is not a joke.
This guy Is great, he had taught me so much that I really appreciate.
I know my bus could use an oil change. But now I should check the fuel lines with the clear tube. I have intermittent boost issues. Itll work then not then further down it works then not. Works less up hills. Thank you for the video
Some really good information here! Confirms my CCC Progress Report theory is not totally bogus for my IHET program ahah
Very nice 👍 guy very informative
Great video s
I have learn a lot
Thanks
Thank you ❤
Great tips
Great video
Thank you sir
You are a very good Teacher, please how can ECM be tested without a Diagnoser .
First of all, I would like to thank you for your help
I have a problem with the generator, as the turbo loads 50%
Replace the nozzles and adjust the valve clearance
I did not get any result
The last low power complaint I had, it was discovered that the secondary fuel filter wasn’t changed in 40,000 miles 🤦🏻♂️
Love ya man
🇦🇺. Thanks for sharing your knowledge always very interesting 🔧⚙️🔩⚙️🔧⚙️
Thank you for your little wrench emojis.
Good stuff
Great video. Do you have any colleagues in the equipment shop that you could teach to make videos like you? I'd enjoy videos like yours about Cat hydraulic and power train systems.
Talking about the chasing of strange symptoms but this was a western star with m11 Cummings same thing warm up periodically engine would fall on face. A couple mechanics tried to figure it out to no avail. Next mechanic a good friend of mine tested the usual. Mine you this truck was being fabricated to be a log truck with Prentice loader boom. His next question was did you unhook the batteries every time they welded they say they did they thought Replacement of ecm problem solved un hook your batteries when welding a valuable lesson I learned.
Well done as always.
We had a truck from a local scrapyard in here that had low power. Not sure who was working on it, but the history was low power, turbo replacement, not fixed, injection pump, not fixed, now the engine blows a rod out the side, they replace the engine, still low power. Now it comes to our shop, we open the hood, give it some throttle, and the intake ducting damn near collapses. We open up the air cleaner and there is so much dirt packed in there we have to pry the element out
One of the things listed (faulty sensor)
But a lot of the people who work on diesel engines often over look at the manifold pressure sensor.
Pop it out. If its plugged with soot. Clean it. If its plugged badly, chances are your intake manifold needs to be cleaned too. A lot of those deposits built up are from your egr and constant long idle.
Whats crazy is the cummins engines that have dpf and def systems can often regen more frequently if the manifold pressure sensor is plugged with soot.
But cummins and the adept ape channel is night and day. He only deals with cat engines.
always love the destruction of the week segments
I try to keep it interesting. We got a Ford V10 locked up in the shop I'm hopeful to get some pictures of it.
Grate info for checking and trouble shooting even I could do this and I don't do macanics.
Why u got one side burn longer than the other ?
Cleaned it and problem fixed
I have a c15 twin turbo bxs no codes on but when I do the flash code test I get about 7 codes I replaced all the sensor but it still gave me the flash codes. Is it a ground problem? Bad ecm? Or just needs a new wire harness? Thanks your videos have helped me out a lot.
Was looking at a 2006 t600 KW with a c15 with 550k on the motor is there anything to watch out for or ask about maintenance wise I see those motors up to almost 2 million
Josh, at 13:16 you state that air leaks between the turbo and combustion chamber cause low boost pressure along with concurrent lower fuel consumption. In my experience, there has been a slight increase in fuel consumption accompanied by with a slight increase in particulate matter, as the decrease in air entering the combustion chamber adversely changes the air/fuel ratio. Then again, I've seen similar air leaks not impact fuel mileage or exhaust smoke characteristics.
Now, could an ECM, sensing low air manifold pressure, derate the engine?
Number one
I been having problems with a c 15 twin turbos when I let off u can hear the turbine still spinning and it does it also loaded what do u recommend
I have a c15 year 2002 I just fix it less than a year ago. I got the whole kit to repair it, plus head fixed. My oil pressure when idling cold 80psi hot down to 30 psi is it normal??? Thx.
With the engine block, can you add inner lining into it so you don't have to buy a new block if you get sidewall damage?
We got 320d2 what causes engine low power only when boom and stick is stalled, thank you
Thanks, I had a bad ECM. Engine load would only get up to 45 percent in ET while running a compressor
Im moving 48,000 km with a kodiak double axle 3126 10 speed and 40,000 axles? Is it too much for the truck ? When I tow it feels ok slow but can do the job easily.
I have a c15 no power. Checked charge air cooler replaced map boost sensors cam sensors changes turbo’s I still have nothing! Runs smooth doesn’t get hot doesn’t miss. Exhausted is clear I have good air filters. My fuel pressure is in spec as well. At this point I have no idea what it could be.
Brand new d9.c18 engine.compared to our old d9r with the 3408 this new one has 25 percent less power,can actually almost kill the engine under load.no faults.
I have a 2004 379 with a c12 mbl19182 with a 10 speed and 370 rears with a complete platinum overhaul my problem is even before my over haul my truck has no power from 8th to 9th and 9th to 10th gear and my pryo gets up past 900 temp from 1st gear to 8th I’m good and it also sounds as if my jakes are on even at idle but sounds worse when running down the road I’ve changed just about everything I can think of from wire harness to a bunch of sensors and even had my ecm checked and tuned I’m lost at what to do to get it to run right
my 3406B has 900,000mi. on the last build. had the rack adj. 70,000mi ago and it is clean as a whistle under the cover. no blow by but consumes about a gallon of oil in 10,000mi {leaks a little at both front and rear seals) is it safe to turn it up a little?
5ek sputters under hard acceleration...or heavy load...thx
I have several late 90s and early 2000 IH with DT466E motors and they all have different hp ratings from 175 to 250 hp the 175 about 195 are real dogs the turbos take awhile to really spool up but 210 to 250 hp spool up much faster but it seems like i get a upper rpm miss fire and it most always is the cam sensor going bad and if you don't change out soon it will leave you stranded its like the engine wants to shut down at certain rpms i think the fuel system is a cat system that they put into ih dt466.
HI , I have a 1994 peterbilt with a cat 3406b 3ZJ44897. About a year and a half ago truck broke down lost a lot of power and was throwing a huge amount of white smoke. Unfortunate for me I couldn't find a cat dealer that would have time to work on it. Took it to a mechanic I met at a peterbilt store, he said he can take a look at it right away. A few mechanics mention that it could be the nozzles so I took all 6 of them to speed up the process. He said that one was bad and maybe 2 more, so I had him replace all 6. After he replace all 6 the problem was still there. He had me rebuild the fuel pump paid around $4000. Still the same problem. He checked the turbo and it was bad, he told me that he only checked one side and it looked ok. Bought a Borg Warner turbo and he install it. I was expecting the truck to run a lot better but for my surprise it was nothing close to how it was running before. It felt like it was missing power loaded, specially going up hill. I finally took it to another mechanic and he claims that the timing was retard two teeth and idle the truck down since it was idling hi. I took the truck and it did run quieter or smooth but still was lacking power. I haul aggregates with a 22 foot dump trailer so a lot of times its on site work and hardly drive on highways. So it takes me a while before I can run loaded on hills or expressways. Any ways I took it to Peterbilt cause they had a cat teacher over there. And again they claim the timing was off and retimed it. They replace the diaphragm and some o-rings. But I still have the same problem, its still smoking more than normal and has low power. I did notice the manifold psi has little psi on lower gears and 14 psi max on 8th 9th and 10th gears. I will check with them and see if they did a fuel pressure and vacuum test. Ask if they did a intercooler leak test. Any advice would be appreciated.
I have a 430D. 5000+ hours. Starts up fine, idles fine, no smoke, past a small Puff on startup. just has 0 power when using loader or when driving. I HAVE to use 1st/2nd gear floored when going up any hill and I’m talking a creeping pace. Wastegate works and is in closed position. I replaced all vacuum lines, checked injector caps, checked boost collar, we replaced both fuel filters, new oil, new filter. Haven’t checked turbine shaft.
I know marine isn’t really your thing, but I have an all mechanical 6140 lugger (Komatsu block) that has a rough idle and somewhat annoying tick below 950rpm. It also blows pretty heavy black smoke at high load. Doesn’t use oil and doesn’t have blow by and still has lots of power. Mechanic has done an overhead recently. I’m thinking injectors, but maybe you have another idea?
What level should the throttle position sensor be I have a scan gauge kr and it shows 93-94 and I have low boost. Pretty sure I need a new throttle pedal
My c15 MBN surges when pulling full load at 16-1700 rpm. Manifold pressure follow the sound fluctuating between 33-35 psi. What’s causing this?
can u explain the vva bleeder screws? do they exhaust oil all the time? my c15 is pushing oil out the bleeder screws on the vva it pushes more oil out on 3-4 and 5-6 1-2 only a little bit
Does the governor match with the injectors. I have 2 different governors and 2 different injectors, are they interchangeable?
What if your getting no blow by no check engine lights . But has low boost about 20 psi pulling a hill. Also getting a lil oil in the air cooler hose connected to the turbo.
About how fast would a f650 with a c7 2007 go down the highway with a full load maybe 2 tons. We also here the belt slip and squeal until it shifts... just seems weird
Hello Josh, I have a 5ek is been swamped from a Kenworth to 1996 peterbilt , and the boost it take about 1700 rpm to start going up any idea, I’ll pass by Idaho on Friday
My truck lost power I turned it off pump the like little fuel air pump turn it back up again and it work well you think it could be pressure?
Best scanner for cat engines? With out going to cat
Hi I have Detroit serious 60 engine light on and off no power boost
I'm getting full revs when it's just on idle but once I put it in gear/load it doesnt rev up past 800rpm1
My excavator has a C7DI engine does hard starting and after it starts, no power to work. What can be the cause?
Hello, I have a cat 3196 Marine Serial No. 2XR 03982, I changed the cylinder head, turbos, official CAT service reprogrammed the ECM and all the correct parameters except the pressure differential of the turbos, everything is correct but it does not go above 1000 RPM under load, in empty it goes perfectly.
Revised fuel circuit, filters, drain valve, no leaks are seen or heard, but the turbos still do not turn up.
What could it be, can you help me?
Can you give us a feedback on low voltage issues in Cat 3406B/SR4 Main Ac alternator
so this engine starts good. no misses. good power. good fuel pressure. after warming all the way up, and drive 65nfor about 1/2 hour, it starts to miss and loose power. i slow down to 50 it smooth's out and power is restored. this cycle repeats itself. sometime i run 65 a short time or a little longer time before it starts to act up again. what are the possibilities?

I have a few problem with the jake brake speedometer odometer and cruse control can yo help me
I have a 93 c12 in a 2000 KW.
RECENTLY DEVELOPED OIL IN THE EXAUST SIDE OF TURBO.AFTER REPLACING THE TURBO ,THAT CURED MOST OF IT.BUT IM STILL GETTI G A LITTLE OIL WHERE THE TURBO BOLTS TO THE EX MANIFOLD. IVE NOTICED WHEN I GO UP A HILL I CAN SMELL BURNING OIL.
THIS ENGINE HAS ABOUT 350 THOUSAND MILES.AND HAS BEEN VERYWELL TAKEN CARE OF.PLENTY OF POWER. BUT I DO HAVE A MINIMAL AMOUNT OF BLOW BY.AFTER RUNNING SOME INJECTOR CLEANER THROUGH IT IT S RUNNING GREAT.
ANY COMMENTS WOULD BE GREATLY APPRECIATED.
Mine runs fine until it gets warmed up and the engine bogs down. Won't accelerate over 45. Pullover, let it sit for 10 minutes. Gets back up to 60 for about 30 seconds. Then bogs back down to 45. Any ideas?
Will be checking all the things you mentioned.

Do u work on maxx force 13’s?
you made me laugh 1:12 awesome video i still use ur videos to learn
I saw the video about putting more power into an engine with original caterpillar parts but I have an E model 2WS so I would like to put a Marine Camshaft and I’ve tried to find the part number but I haven’t t been able to find it ,is there any way you could help me?
your e model is the best engine out there turn it up to 550 and it will pull like apro and get good fuel milage
1989 cat 3208 in a 40 rv has no speed up hill runs fine on flat road, any ideas?
How many psi your gauge should read it n a cat c15?
Hi mate,
My Sandvik DX800 has C7 Acert
Since couple of days engine is stowing while working.
What I should check
Low engine performance caused by the driver's seat exceeding max load rating?
Lol.
hahahahahha
@@arturopadilla2135 . Good day ,sorry my engine is a mercedes glk 220 cdi engine and am getting this two codes
1. P024028. The Boost Pressure Sensor For The Low-pressure Turbocharger Has A Malfunction.The Signal Offset Is Outside The Permissible Range.
2. P010628 The Intake Manifold Pressure Sensor Has A Malfunction.The Signal Offset Is Outside The Permissible Range.
Have changed the both sensors and it's still same. Thanks, Hoping to hear from you soon.
Hello. Love your content. I do alot of the basic to moderate mechanic work for our company. We recently encountered a problem with our cat15 motor. Scenario goes like this. I drove it up a mountain with a lowboy on the back and it hauled it perfect. As it warmed up it starts to miss. We have had 2 different mechanics look at the issue. We have done a full service and found one of the injectors not seated properly. They have done dead cylinder tests and still the problem persist. We have pressure regulator on order as well as spring kit. Beyond that we are at a loss of what it could be. We are running wix filters also. Could those play into fuel problems? I know cat filters are king but would wix be really that bad? Thanks for your time and for content. Have learned alot from these videos.
he never did answer?
Hi. I have a atlas copco XAHS 347 air compressor & it have CAT C7 engine it have been working great untill now when lode giving time heavy black smoke coming.. I checked the turbo it has small Shaik ..the turbo oil return hose was leaked & engine oil was leaked...befor this happen.....can you please tell me what is to be checked to find the problem...
What do I do if my engine is not getting to full rev (it stops and 2200rpm) and has low throttle response? (I have a cat c13)
