- Another video just showing you how to check for your turbo or actuator being bad. Very common for both of them to be stuck, but sometimes its just one thing stuck but I always recommend still replacing both at same time. Stay tuned for how to install turbo and calibrate actuator to it video.
Honestly thank you very much for this video this has helped out so much..
So many diesel mechanics dont even know this
You got lucky I can't remember just how many times I broke the actuator mounting bolts. Ty for the memories 👍🇨🇦
What were the symptoms like what did the driver say started happening before it came to this point?
Pretty smart. If actuator gets stuck in stage three jake position the truck will choke itself. You are correct. The actuator has to be calibrated when replaced also or failure wil result.
Btw i hate this set up for actuator and really don't like the vg turbos. However in stage three they really work well in braking.
You’re a good mechanic, but you need better tools. Thanks for making these videos and putting yourself out there. I’m definitely not being negative man.
There’s nothing wrong with his tools 🤦♂️
lol that ratchet is way too small need more leverage
The Spector gear is bad, good stuff brother glad I ran into this channel .
Sector *
Are you sure that VGT motor should move freely? most electric actuators won't move freely. Maybe it was just the turbo stuck ?? Can you do any repairs on those turbos? I know on the Ford 6.0 you can replace or clean the center section. Just curious because we just had a 2014 6.7 Cummins School Bus fixed and they replaced the Turbo & Actuator, costs about $6000, seemed a little high to me.
Larry Robinson yes, pretty sure they should move freely. Should move almost with no effort.
The sector gear on the turbo should move freely. The actuator motor doesn’t move by hand, computer controls that.
jay hyland yes computer does control it but u r still able to move the actuator by hand.
Show me on a new one
jay hyland go watch my how to calibrate actuator video. I spun the actuator with the key off... brand new actuator
Can you replace both with a different non expensive turbo and actuator?
Awesome Video!🎥
Do you know what is the part number for the first line that you unscrew my truck is leaking from that line thanks
Very useful information. Thank you!
Michael Novak shouldnt be hard at all. Barely any force should have to be used
I have a 86 pete with a 99 n14 Cummins in it.
It runs but on acceleration especially when loaded it makes a sound like my Jake's are running and is really sluggish then after a few minutes or in certain gears it powers back up and sounds normal until I change gears then it starts the loud poping sound and gets sluggish again.
I've asked two mechanics and they said its either something wrong with my injectors or my Jake's but I'm beginning to think it's my turbo.
Any ideas?
Could be bad injectors just take the jakes off plug the 1/4 inch oil supply and run it with out jakes if it does the same injector s. They going bad only at high rpms
It was a bad turbo. I rplaced it and it fixed it.
the hell with this newer engines, they suck, can't wait to said goodbye to all this BS global warming crap.
I have oil coming from the back of my brand new turbo plus I just had it overhaul. The guy telling me I have a bad valve seal? Any suggestions
Crankase filter clog
How often does the actuator get damaged when the turbo seizes? Is it every time or ?
If turbo is seized, i always say to to replace actuator to not have an old actuator take out a new turbo.
But alot of times its different, sometimes u take an actuator off and its bad, and turbo moves, sometimes turbo is stuck and actuator still moves
I had to replace my VGT but my actuator was still ok - they said the actuator is an electric motor that was trying to turn over and over it may appear it is fine but 90% of the time the actuator has been damaged from trying to turn over and over - if you replace the VGT you will be time and money ahead if you replace the actuator at the same time - Btw good Video thanks
Bill Carson that is exactly what i tell my customers. Better to spend a few extra bucks right now on a new actuator than have it go bad and take out ur brand new turbo.
My 2015 Freightliner Cascadia is blowing or what is wrong what is a call Halia
I was sure I had a broken exhaust bolt on my manifold. Loud whistling nose coming from left side. Usually you can see black soot but this time there was none? replaced turbo and actuator and still have the same issue but my turbo dumps boost after 75%. could it be the ECM? no codes though?
Have u pressured checked ur intake system? Cracked intercooler, cracked air boots for intake?
Got the truck to Cummins in Spartanburg and Tech found the problem in less than an hour. EGR return hose. Up underneath the back of the motor. Funny Kenworth and Peterbilt couldn't find it?
Why the turbos are failing so often
I mean I have replaced 3 turbos within 4 years
And those suckers are not cheap either
They are close to 5k
Jorge millenia backpressure, aftertreatment.
Thats why u need to be buying turbos from me ;)
BulletMcNugget how can I get in touch with you
Jorge millenia email me maximus_516@hotmail.com
Jorge millenia oh and i saw u commented on a video of mine a long time ago that u had ur truck deleted. If it was done wrong, that can be the cause of ur turbo failures. To much back pressure, too much boost for that particular turbo etc
BulletMcNugget could you be able to fix the problem of that.
So if that lever on the turbo wont move states that the turbo itself is bad?
Yes, correct
@@BulletMcNugget thank you!!!
There is an option also besides to be towed, hammer a little bit if you cannot move freely the lever from close position to open and you good to go
But didn’t screw back the actuator back , i was planning to drive 2000 miles home loaded to change turbo , but in about 1000 mile in the morning i screw back the actuator to turbo and my turbo is still working, that was about 200k miles ago , didn’t even calibrated,no issues
@@peterbivol2865 lucky u. What year is ur truck
My truck sometimes don’t move and don’t respond at all doesn’t move and start black smoke like it got chocked from close to the turbo. Idk the reason can anyone help with tjis case.
Sorry for being new to this s stuff but could you not check this without draining the coolant??
Lee Hill u cannot. There are coolant lines that go to actuator and have no play in them, so to remove actuator, those lines need to be removed and to remove the lines, need to drain the coolant.
@@BulletMcNugget hello i know the video was from a while ago quick question regarding the draining. If the truck is cold and not hot or anything does it still have to get drained or just removing the lines will be ok ?
Thanks
Yes u can the lines can bend a little enough to get actuater off u dont have to drain system when cold
bro i have a m11 celect plus yellow amber light comes on and off i put on cheap scanner it s saying timing actuator can u tell me what means or where its located
sid 84 timing actuator #2 thats what ancel scanner saying plus in the morning its like the fuel filter is empty give me hard time to run right only in the morning coulb air in the system or fuel returning to the tank can u help
Do I need to drain out the antifreeze for check the actuator？
Eason Ma yes
No only a little comes out on a cold motor
@@BulletMcNugget no u dont need to drain only a little will come out if cold and not pressurized
Good video. . Im at this point myself.
I have a squealing/screeching noise (very annoying) coming from left side, I actually thought it was coming from front of engine. I replaced clutch fan and tensioner pulley still screeching and squealing. No check engine light. Turbo boost kicks in when it's suppose to! Even when it's idling you can hear it whining.
Is my turbo bad?
I have the same problem and don’t know what it is. It really annoy me.
Good work
Hi . please help . i have P0045 fault code . is it mean bad turbo actuator .?
Its possible. Gotta be diagnosed
What cause oil to get into your coolant reservoir 2007 international 9200i I replace the oil coolant and oil still gets in reservoir any help please
Accura Williams u replaced the oil cooler already? All the orings and gaskets were replaced?
Trying to figure out wuz going on with my truck I have a 2014 international prostar trubo went bad about 4 most ago replace the trubo and last month actuator went bad replace that to. Was loosen power check engine light came back the code is reading 641 fmi 9 for the. For the actuator took it back to cummins for them to replace the actuator they said they replace it. And the one I just bought the part was bad and ran a regeneration pick it up out the shop yesterday on my way home check engine light came back on saying the same code
rashondra bowen whos installing it? You or cummins? Cause it has to be calibrated. And could be wiring going to it. When I was just starting off at dealer, i diagnosed an actuator too and replaced it and problem stayed and ended up being a wiring problem... but if it says mechanical not responding or out of adjustment then ye, thats just turbo or actuator.
Cummins doing all the repairs
I even bought the part from them. Both parts are new turbo four months old and actuator only one month they replace the actuator yesterday because I was sold a bad part got it out the shop yesterday on my way home and the light came back on I have replace the turbo, throttle value and the actuator in the last 4 month's
I have 2014 international pro star and I happened to have the same problem. Bought new actuator and it was installed and did the calibration, however, it keeps saying software update. I took it to Cummins dealer and they told me to change Turbo. I have spent time and money 3 days in a row and I'm getting ripped, any idea I will appreciate?
Thanks
Those actuators should absolutely not spin freely by hand and forcing them to do so can lead to damage in the stepper motor FYI you should only ever turn them digitally via laptop/insite
If you turn the key to the on position it should spin when it does its system check. Easiest way to see if it's functioning since not ever one had a laptop
I have question: I got a 2014 isx15 2350 and I dont see half a hole when I move turbocharger sector gear to the left. Does that mean my turbocharger is bad?
m213 ill be honest, i forget how the isx15 turbos r but i believe those r different, u dont see the whole half, u see a little bit. Its only on the cm871 that half a hole is visible but again, i cant remember on the isx15 if that is the case. R u having codes for it or what?
if i want open actuator do i have take out all coolant
No
Can your VGT actuator be bad and not give you a check engine light or fault code
Gregory Arthur its possible. Ive had that happen twice before. It wont do a regen, or wont get hot enough to finish a regen cause turbo is not moving all the way..
Ok so I took my actuator off everything spins and moves freely so back to square one ..
Gregory Arthur whats going on with ur truck? U also want to make sure ur turbo goes all the way to left and all the way right
Well for a while now its just has no power between 1300 and 1450 rpms when loaded and pulling hill it starts shaking and missing like it's being choked out or losing fuel but I've had it to shop several times and theres never any codes and they can never find anything wrong but here in the last week when u run for a few hours and come to a red light or have to stop for some reason it starts whistling like it's trying to regen . Kinda like u said in ur first post about the accelerator being bad but not throwing code
Gregory Arthur injectors maybe? Any fuel pressure codes? Id check the intake manifold sensor, ive been meaning to make a video on that on how important cleaning or replacing that sensor is. It might be plugged up and truck is lagging cause of it
If someone broke down with this problem on the road with it being choked out. Could you pull it apart and push that arm on the turbo open more to get it back?
s c it would be stuck most likely, so no. If the actuator was just stuck, yes, move the turbo open and slap on actuator and get wherever u need to get too...
Thanks! I was curious what's your opinion on 2014 mack motors
s c cant give u an opinion as I do not know much about them, but i know theyre close to volvo engines and those arent my favorite... but like I always said, everyone has there own opinion on every engine.
Its hard to say these days what motors are reliable with all this emissions crap put on them.
s c exactly. The engine might be good, but majority of failures that happen on any engine are due to the exhaust recirculating and all of the emissions stuff.
Yes I replace them
Great video
Carry on
Como localizar el enfriador del aceite en motor cumins ?
Enrique Lopez locate the oil cooler?
Put a Detroit turbo on it that's what I would do Cummins is junk anywhere
Es una lástima q no contesta a las preguntas:(
why does most everyone where gloves these days.
Steve C because used motor oil is a known carcinogen
Cause Cummins makes you😂😂
Want to enjoy more then 2 years after retirement and not die due to the chemicals we use on daily basis 😂
Bc theyre pussies 😆 cant get their nails dirty
just watched if turbo is bad is vgt definitly bad as well
My truck dosn't have a turbo actuator. Problem solved I guess.
Got the sid27 code out of calibration,
meekeedutska turbo or actuator. One of those
BulletMcNugget i changed the actuator and its running but got that code and says stop engine falt
meekeedutska did u calibrate the actuator?
BulletMcNugget yes manually,
meekeedutska how do u mean manually? Not with insite?
Isx???? .... So it's an EGR model engine ....
Meanwhile China a lot of pollution at admosfer.
These new trucks suck ads especially when the but turbo is sealed and non serviceable if you buy a truck make sure it's not some stupid ass patnend where there are no rebuild kits available and its only 1 source to buy turbo for some outrageous rediculuas price like Cummins does do your research before you buy a truck a holset enclosed turbo is 3k and up believe I know the hardway
Reject
Thats happening to me at this moment
Rolando Lopez if you guys need parts and cant find it, like these actuators and turbos especially for the cm871. Let me know cause I keep quite a few in stock and I can ship u one if needed
BulletMcNugget thanks
Rolando Lopez me tio
