John Deere 9570RX - Cummins QSX15 Engine dies - Diagnostics & Repair 

Mornin ZK and crew. 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.

Love watching you work on and explain how it works and what it does thank you 😊

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

Yes, enjoyed the Cummins diagnosis! Like their engines ! Stay safe !

That’s an awesome video your videos just keeps getting better and better

Thank you for sharing your expertise once again. You do your part to keep the green machine moving. 😊

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!!

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!!

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

This was cool to see the fuel pump replaced but I feel sorry for the farmer.

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!

My new favorite channel. Don’t know anything about combines or tractors but I love it. Well made and narrated videos.

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.

My grandma (Sweedish) used to have UFF-DAH signs, paintings and photos all around her house. Good memory, thank for the laugh

You always make it look so so easy

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

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.

Another great video. Always makes my day when I can watch you work. It’s would be awesome to spend a day with you.

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

Great show keep up the great work

Love your videos Always looking for the next one !!

not a mechanic but i enjoy watching your videos great Work.

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 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 .

What a beast! Keep the deere's running! Nice vid

I appreciate all the good info that you share. Awesome content! 👍😊

Great video 😊 You know what downing Great machine you are Thanks again Greg

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!

You are awesome , its Almost nice to See you repair something🙃 stay Safe 🙋🏼‍♂️

Used to run these QSX engines in the red and blue 4wds and they’re a brilliant power plant IMO

I appreciate your videos.

U R TOTALLY AWESOME AT WHAT YOU DO. FINE THE PROBLEM &U NOT GUESSING AT IT.

You the man ZK

The right tools makes the job so much easier

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

Great video!

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

Thanks for the video.

Dam good job zk

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.

Thanks for sharing

Nice fix ZK all looks a bit tight and uncomfortable to get in the right working position 👍👍👍👍

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. Steve

Great fix. Seems strange to have Cummins power on a Green Frame. A challenge to keep abreast of what is out there.

Great job , thanks

Been missed!

Good morning Good job

You the man!

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?

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

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?

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.

I always like when u say the total hours on the u it’s u work on.

Great video as usual. Just wondering how the fan is driven on that tractor. Hydraulic?

Thanks for sharing your knowledge Zeth 🦘👍

Nice

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

Beautiful job,is HD going to start to build big horse engines.

Does the radiator fan use variable pitch blades?

Гарно працюєш😊😊😊

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…

NICE AUDIO WOW 16:20

Enjoy your videos. ZK, could you not carve up the old transfer pump to make a locking tool?

Adding insult to injury...new starter required...good times.

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

That tractor have a chip on it? Grey box zip tied to the wiring harness.

What’s the price tags on those pumps? Is that a warranty job?

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👍

How many hours were on the machine?

Paint does not an engine make ! Have a great week end.

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👍👍👍👍🍿🍿🚜🚜🚜🚜🛠🛠🛠🛠😎😎

👍

So I am wondering how he can verify the pump timing is correct and it did not shift a tooth.

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

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?

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!

What do you know about new13.6l engine

big dang HP/LP assembly fer sure

Do you prefer working on the cummins powered John Deere’s or the ones powered by a Deere engine

No sabia que john deere coloca motores cummi ?😮😮

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.

Wonder what that new injection pump cost....

Why is the fuel pump “timed”?

I’m surprised pulling and replacing those drive pins isn’t a repair option from john deere. That pump can’t be cheap.

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.

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.

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???

got love the engineers let them pull wrench once or twice lol

Zeth , have you worked on any of the john deere 18 liter engines yet?

Kinda mysterious why those pins would go

Have you invested in a Milwaukee heated jacket? They are worth it.

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!😬😬😛

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 - for what is worth, my interests are in tractors and tools. What pen light do you use? Cheers!

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

It's possible that the gear that is driving the fuel pump is slipping.

Does Sloan pay for you class and JD Certs it is that on you to keep up to date

How long has Deere and Cummins been working together. Just this one size of tractor?

No pump calibration on those puppies?
