John Deere 9570RX - Cummins QSX15 Engine dies - Diagnostics & Repair
HTML-код
- Опубликовано: 6 янв 2025
- Got a John Deere 9570RX with a Cummins QSX15 that will start and run for about 60 seconds and then it will die. Starts right back up but will die after 60 seconds every time. In this video, I will show you how I got my diagnosis and I will show what it takes to replace the high pressure fuel pump.

I've drilled and pulled those pins before. It's one of the frustrations of Cummins (and other manufactures) using goofy drive couplings like that. I believe the failure mode is material fatigue. Lot of vibration in those systems, and the pins are hardened. Eventually they fracture like icicles.
My new favorite channel. Don’t know anything about combines or tractors but I love it. Well made and narrated videos.
Glad you enjoy it!
Too bad all JD franchise owners don't see that their technicians are properly trained. We have experienced allot of incompetent mechanics working on our green iron, especially in the last 6-8 years. Many of the ace mechanics are leaving our local dealer. I appreciate your professionalism.
hate to say it , but Deere demands more training than most , but still true ,dealers , all of them aim for MINIMUM training for all colors . if it aint demanded and follow thru , with warranty loss for ignoriing training , dealers dont care , mostly at the top management . LOWER manglers , will also shave training IF they work with a BONUS for "saving $$" each month . then the problem becomes worse and top managers just shrug . Kubota , i recently worked with came to dealer , specifically to ask shop techs questions and concerns . TRAINING was at the top .
A lot of the tech don’t get enough Traning on the new system because either there to busy or don’t want to spend the money to train there people
A lot of times the problem is the techs stay a little while and realise that working on equipment is actually work and leave to go make more money and work on cars in the air conditioning. Or the second problem is dealers that get a good tech and don’t pay enough to keep them.
@@timblack33 because good mechanics aren’t paid enough for the work which is why everyone is always hiring them. 2 of my very good friends both went to college to be diesel techs, stayed in the industry about 10 years and left. Realized the money wasnt there for the amount of knowledge they had.
@@kylem9834 you’re exactly right. I’m seeing wages go up across the industry but they’re still not where they need to be. I hired a former freightliner truck shop service manager last year and had to pay him healthily but it’s been a great investment.
My grandma (Sweedish) used to have UFF-DAH signs, paintings and photos all around her house. Good memory, thank for the laugh
Lol Cool Swede Gals are Cool
Where it says insert pin not for TDC and its just for timing engine. There is a mark TDC and then A, B, C for setting overhead. You mean tool 5572562 for high pressure pump. They did have 3 cyl high pressure pump they were heavy. But in truck chassis they came out from bottom while dripping oil on you
Zeth, I like how thorough you are explaining what the actual problem is and how you're going to repair it step by step. Your knowledge is amazing. Keep the action coming definitely seeya at the next one. You stay safe!!
Im a retired HVAC technician/ service man. Enjoy your taking us thru on your service visits. Its a cold day here in North west Iowa. Thanks again !!
I was back in my hometown in Decatur in August ,wanting to take a drive to Arthur but didnt havecthe time this time. Keep the Green Iron moving
All very well done big fella, but from one cummins tech to another, put something over all your lines when they aren’t connected, those systems on X15’s tolerate absolutely zero contamination. All In all but a neat job man, keep up the good work on those green machines brother
Another first class job Zeth, but I have to apologize as I was shouting at the screen, "Zeth you forgot the stud for the clamp that needs to be started before you tighten the main pump", but I should have known you had a plan all the time for the little sucker 🙂. I was always getting told to keep my mouth shut! Thanks for making these great videos.
I was the same 😂
In the older isx engines, when the hp pump comes apart it would shear the pins off. Might pull the head off the hp pump and see if the tappets or cam is flaking.
Looks cold up there brother. We're still in shorts down here in Baton Rouge. It doesn't really get cold here until February, and that's the 30s and 40s. Stay safe, awesome channel!
I put a alternator on a RX today but haven't had to work on them much. Had a couple bad turbo actuators and a waterpump last fall . Did have to replace a high pressure fuel pump on a 8430 a couple days ago . Shaft twisted off. About the same type of pump just smaller .
you downplayed it but setting the new gear to the old gear posiiton perfectly and then hoisting that heavy sucker up and getting the pump set in position with the gears meshing as they should took an easy gentle touch - good on you
Am also a JD Tech in Canada here but i work as a John Deere mobile golf and turf equipment tech have some training on your side also but your vids are great as am still doing learning Ag side keep up good vids man your helping me learn lol some of the tech classes are a bit hard at times
Love watching you work on and explain how it works and what it does thank you 😊
This was cool to see the fuel pump replaced but I feel sorry for the farmer.
Nice job on getting it out and back in without the tool. I'm guessing you could mark the end with the dowls before it's taken off as a bit of insurance in case the gear moves when you slide it out. Thanks!
Great fix. Seems strange to have Cummins power on a Green Frame. A challenge to keep abreast of what is out there.
Yes, enjoyed the Cummins diagnosis! Like their engines ! Stay safe !
That’s an awesome video your videos just keeps getting better and better
Just curious as to why you need to time the high pressure pump. Doesn’t it provide a continuous pressure that is controlled by the pulses of the injectors? Great video…
Just a guess. Cummins decided to time the high pressure pumps internal rotating parts to the engines internal rotating parts to enhance engine operation, relative to controlling the natural harmonic frequency of working parts together which helps with noise control and parts longevity. This timing does not appear to be relative to start or end of injection.
@@2011Harvesttime Cummins employee here, yes its because of harmonics and balancing. Same reason you have to time the air compressor when installing it.
@@Datsun280zeeee interesting…thanks!!
When injector opening causes a pressure drop in rail the HP pump being on a discharge cycle offsets the pressure drop and assures more accurate fuel volume delivery. The pressure cycles in rail are reduced and the hydraulic resonance is diminished. Before the pulses were synchronized there were some engines that would have coarser idle and some that saw rail pressure sensor life too short. There were some systems with an accumulator to suppress the pulses, likely still some with something to deal with the unbalanced pulses.
great job, excellent detail on the repair, great to see just a fitting of pump and no diagnostics needed to start up, love the videos, keep up the good work
when you find an issue as the long bolt on top of the fuel pump, do send back a notification to the engineers to supperseed that bolt?
That tractor have a chip on it? Grey box zip tied to the wiring harness.
Used to run these QSX engines in the red and blue 4wds and they’re a brilliant power plant IMO
You make it look so easy I once removed a fuel injector pump at the governor section(Detroit I think). Was trying to be quick ended up costing me half a day fixing that mistake.
Everyday is a new adventure when you are wrenching! I replaced a starter on my girlfriends, now wifes car 35 years ago in -20° weather laying on a street in downtown Mpls.
Nice fix ZK all looks a bit tight and uncomfortable to get in the right working position 👍👍👍👍
it looked like you forgot about that pesky top clamp bolt until you 'splained the method to your madness. I often wonder whether (Cummins?) looks at the cause of failure of the pins you found sheared. 1,400 hrs seems too pre-mature a failure
not a mechanic but i enjoy watching your videos great Work.
The right tools makes the job so much easier
Does Sloan pay for you class and JD Certs it is that on you to keep up to date
Yes sloan pays me to train.
@@ZKMasterTech great news. Many dont
Thank you for sharing your expertise once again. You do your part to keep the green machine moving. 😊
Wow question did they send that pump back to Cummins? They rebuild it, get it back to factory specs and put it back out the Fleet.
Have you invested in a Milwaukee heated jacket? They are worth it.
Got one!
Great video as usual. Just wondering how the fan is driven on that tractor. Hydraulic?
Yes the hydraulic pump runs a hydraulic motor that turns the fan.
Thanks for sharing your knowledge with the rest of us. I'm sure that with that wind and the 40 degrees it was a bit cool out there!! Reminds me of working in the quarries!! Stay Safe!!
I always like when u say the total hours on the u it’s u work on.
What a beast! Keep the deere's running! Nice vid
Love the vids mate great job. My question is is there anyone who repairs agco product's and film it like you do. Im a agco tech never really worked on deeres id like to see any agco techs too
I haven’t seen any
U R TOTALLY AWESOME AT WHAT YOU DO. FINE THE PROBLEM &U NOT GUESSING AT IT.
Waiting to see if you got the ceramic high pressure pump or the steel plunger, high-pressure pump, my guts, telling me the ceramic grace and peace
why do you have to set the fuel pump on time, its a comonrail engine if i am correct, the ecu takes care of the injection time not the pump. the pump only supplies the high pressure fuel. your channel is great, hope for more videos. greetings from the Netherlands👍
You have to set timing on Deere common rail engines and Cummins
Why can't these pins in the transfer pump be replaced by bullet gear drive couplings?? Cnc milled gear ⚙️ on back of fuel pump with male side and transfer pump with female gear ⚙️ inside. Similar to Series 60 Detroit oil pump??? Get rid of pins for something more reliable???
You always make it look so so easy
Wonder what that new injection pump cost....
Zeth - for what is worth, my interests are in tractors and tools. What pen light do you use? Cheers!
I use a Milwaukee rechargeable and a steam light
Do you prefer working on the cummins powered John Deere’s or the ones powered by a Deere engine
Great video 😊
You know what downing
Great machine you are
Thanks again Greg
Another great video. Always makes my day when I can watch you work. It’s would be awesome to spend a day with you.
What do you know about new13.6l engine
I appreciate your videos.
Adding insult to injury...new starter required...good times.
I was puckered as he put the HP pump in place. Heavy plush a bit awkward makes for want to hurry. Until it it mated up with a bolt to hold, I felt like walking on the high wire!😬😬😛
Sos un feliz privilegiado el poder tener la mejor marca del mundo que es John Deere. Su color verde lo hace único se confunde con la naturalezza. Es la máquina que más genera producción por cada litro de combustible que gasta. La comodidad de trabajar con estas máquinas está pensado hasta el mínimo detalle, trabajar con estas máquinas no es un trabajo es un placer.
¡Gracias!
Does the radiator fan use variable pitch blades?
I’m surprised pulling and replacing those drive pins isn’t a repair option from john deere. That pump can’t be cheap.
ZK, or other John Deere techs...if somebody were to be retiring from the military with plane mechanics (specializing in electrical) background, what would be a piece of advise you would offer them when trying to get into the Ag Mechanic trades? Love watching the channel!
Just apply and if you get the job, team up with a good tech that will teach you. That’s what i do with Josh.
@@ZKMasterTech is there anything college wise that I can do now that would benefit the company or myself in the trade if i were to do it for the long haul?
@@cashinpoole8494 Look up the JD TECH Program. There are colleges around the country that offer this program. It may interest you. The program provides a 2-year associate degree which includes general education courses as well as John Deere exclusive classroom training
Just a few thoughts..I really enjoy watching Zeth's videos because I did similar work with a Case/IH dealer in northern Iowa. My military background was M1A1 and anything smaller than that in the motor pool. If you are in aviation now..why not stick with that field? Secondly, Make sure that when you are in the ETS phase make sure that you convert all of the military training into college credits.
@@marksawyer5299 where we want to retire to, there is no close by air fields. However, there is a large John Deere dealer for the area and i enjoy fixing things.
Nice job Mr. Z! Looks like winter is around the corner. Do your customers usually have routine maintenance and postponed repairs performed during the winter months?
Yup
Thanks for another great video.
It was interesting and enjoyable.
Wow. Good one ZK.
That may look fairly easy BUT getting that new pump in there was a hard and one half job if you know what I mean. Almost need four hands to get new pump in there.
But you did it. Nice job ZK.
Interesting how you figured out what was wrong. Not the easiest place to remove and replace.
Thanks for showing us this one. Most interesting.
You take care and be safe.
Looking forward to the next video.
Thanks for everything ZK.
Most interesting video.
The Iowa farm boy.

What’s the price tags on those pumps? Is that a warranty job?
u could make a little adjustable chair to sit on, slides onto the track and locks on the cleat make it out of aluminum, won't be the last time you work on tracks...Great Vid👍👍👍👍🍿🍿🚜🚜🚜🚜🛠🛠🛠🛠😎😎
Great show keep up the great work
Why is the fuel pump “timed”?
So I am wondering how he can verify the pump timing is correct and it did not shift a tooth.
Interesting ordeal, I am a road tech on New Holland tractors. Our 15L Cummins do the same thing but primarily on silage pushing tractors.
Zeth , have you worked on any of the john deere 18 liter engines yet?
Not yet
No sabia que john deere coloca motores cummi ?😮😮
New subscriber here. I put spark plugs and an air filter in a John Deere X300 last year. Would that make me a junior tech?
Hi Zak is that a different fan setup or a different engine, to the ones where you've had problems with the fan drive pulleys which had modifications done by deere
On the Cummins engine there is a hydraulic fan
How many hours were on the machine?
I appreciate all the good info that you share. Awesome content! 👍😊
We do not know what caused this problem so why would the fuel filters not be changed at this time as well . Just for preventive maintenance action .
I changed them
@@ZKMasterTech I do not think that was covered or said in the video , Thanks for the video and the reply .
Yeah i did that while i was waiting on the starter to be brought to me because i Serb the low fuel pressure code. Just forgot to mention it.
You are awesome , its Almost nice to See you repair something🙃 stay Safe 🙋🏼♂️
Beautiful job,is HD going to start to build big horse engines.
Paint does not an engine make ! Have a great week end.
Enjoy your videos. ZK, could you not carve up the old transfer pump to make a locking tool?
Hopefully I’ll have the special tool by the time i have to do another one
No pump calibration on those puppies?
You the man ZK
Thanks for the video.
Dam good job zk
big dang HP/LP assembly fer sure
Thanks for sharing your knowledge Zeth 🦘👍
You are not far from Peoria.
The profit for small JD equipment isn’t there for a dealer to send their techs out and still make payroll. When you start selling equipment that’s deep in the six figure range you can afford to do that. Not saying the mechanics don’t deserve it but the owners got to pay for all those fancy trips and keep the family looking good
Kinda mysterious why those pins would go
Good morning Good job
It's possible that the gear that is driving the fuel pump is slipping.
Great video!
How long has Deere and Cummins been working together. Just this one size of tractor?
Since the 80s, I believe. Cheaper to use a proven engine than design your own from scratch.........
Cummins engines show up everywhere, not just John Deere.
The 9R tractors have cummins in the 570hp and up. They will be replaced by the new Deere 13.6L though.
Why does Cummins want that pump timed?
I guess in my next video I’m going to have to explain why because I’ve got a ton of questions on that.
@ZKMasterTech did you ever address this?
Great job , thanks
You the man!
No you’re the man! Lol
Been missed!
Too bad there weren't more mechanics that became engineers. Have to love spending a half hour+ removing pieces and parts to do the repairs, then put it all back together.
Love your videos Always looking for the next one !!
a green cumapart
Isn't it a common rail engine?
got love the engineers let them pull wrench once or twice lol
👍
