Harvest service calls 2 - John Deere 9520 engine knock & 8320R is getting hot.

In this video, Patrick has a 9520R with a nasty knock in the engine and I hit the road to go finish up the 8320R fan drives. Got the parts in to install new dry style fan drives on an older Teir 3 8R 9.0L engine. Customer is still complaining on the tractor getting hot so we try a set of thermostats. Then I go back to the shop to see what Patrick has found…

You’d think, for how much these tractors cost, that they’d be trouble free for a decade with a good service history.

[@dustinb9105]

We don't live in a perfect world. Even new stuff will fail.

[@Beyonder8335]

Anything will fail. Farm machinery usually gets pushed pretty hard too so that puts more wear on it.

[@mitchellunger9005]

Yeah over the road trucks sure last a long time don’t they? It doesn’t matter what it is. If it’s pushed hard and past its limit it will fail.

[@hermanbishop5275]

Too much stuff on em

[@crandonborth]

@@mitchellunger9005 Highway driving is far easier on an engine vs pulling in a field all day.

[@mjh7610]

Wow. One hell of a mechanic! Someone that actually uses torque wrenches and understands why you do.

[@heatherkohlwey8379]

Thank you for taking time to share another great video, Zeth! Thank you for everything you do to keep harvest going. Please stay safe, and God bless.

[@rdyardie]

I am always impressed to see how professional you are. You simply know what you are doing. That is a real treat for me. Thank you.

[@iraisaacs4446]

I always love seeing situations where companies are lucky enough to have an employee like you. We had some pretty good techs that worked on our equipment at the farm.

[@kobemelendrez1303]

As a John Deere field technician, you are a role model of mine for a while now, your videos helped me so much, we are at Campbell tractor in fruitland ID, youre tips are amazing and I used them everyday now thank you!

[@marcusjames3814]

Um a john deere setup technician and my friend zeth's technics are legendary

[@braxtonfontenot5119]

Great video. Excited when I see you post a new one. Keep it up

[@joelluehrs6143]

Our New Holland TM 140 has 24,578 hrs and the motor, trans, and rear end have not been opened up yet. Love your videos.

[@crandonborth]

Walked in our Case Dealership today... 1 Quadtrack was getting it tracks replaced and 9230 Combine was getting a rock dug out of the rotor... otherwise it was crickets in there. 😂

[@amunderdog]

16:00--- It is always nice to know, the engineers thought of the Field mechanics.

[@enderlane]

Couple things I’ve learned over the years on these. First is you don’t need to remove the hose to pull the fan drive. Second if you remove the boot that holds the cooler lines to the water pump housing, the hole allows the bearing cavity to breathe and can aid in removal and installation of the driven assembly.

[@RealJohnWayne]

Another great video ZK, lots of work going on! It's incredible how fast you work when you're jamming to the music, maybe you should jam more, and save the customer some labor time? 😅 "Nothing Runs Like A Deere" 🦌 👍 🇺🇲

[@frasermathers2287]

Great video Zeth and the place is a hive of activity with everyone being busy as bees! As is the case in all modern vehicles/equipment, regardless of cars, commercials or agricultural equipment, there is never enough space to get to parts that need changing like on your 8320R, but you got her done.

[@2491kridge]

You got that right, I’ve been an automotive tech for a bit over 15 years and the cars are just getting more and more jam packed as the years go by. You’d swear they build some of these cars as if they’ll never have to be repaired, just stick the entire engine bay and transmission on a table and then build the car around it lol

[@shanegouker1628]

“ it is a bomb, so you gotta be careful “ lol. Love this channel!

[@jacobbuckley8232]

Man thats crazy those nice expensive tractors having problems like that

[@catsmr]

Thanks for bringing us along!

[@williamorman4779]

Thank you zeth ,its a hand full runing the buggy

[@henrythiessen9084]

First Gen r series, absolutely my favorite 8000 series ever. I feel like they all run a bit hot, though, but not really too hot. We had an 8270r with 13k plus hours. In the summer, it would get to 225 degrees Fahrenheit. But overall, it had less problems than our newer 8285r with 5k hours.

[@mikewoods6474]

I’m a farmer in central Mississippi. Really enjoy your videos. Keep them coming when you can.

[@alisciamarotta3888]

Ty for another great video Zeth. Always enjoyable, interesting, informative, educational and entertaining. All along never knew what what the " K " stood for.....till you showed the tool that dad made ( impressive ). That does fits you, the Key to success 😊.

[@johnkruger3661]

Good videos mate when I was young all I needed was a 12” shifter .Hardly needed to use it .I had Fiat’s never replaced a water pump some tractors done 15000 hrs .But alas today nothing lasts . Keep safe

[@chrisgossman6512]

It's always nice to be able to catch one of your videos. 👍 and subscribed. Happy subscriber 😊!

[@saqibnawaz5139]

Vry wonderful professional john deere fan drive repair is made it was quite trickier but vry professionally achieved by legend of ZK MASTER TECHS Undoubtedly

[@patricktwohey7925]

Ive watched all your videos for a while now. I love watching someone do what they are so good at. That being said, Ive worked in Aviation my entire life. Military, Airlines and Corporate. From day one the rule was always never wear any jewelry. Rings and watches especially. It's not worth it to have your finger torn off your hand by some freak accident. Keep that green iron movin!!

[@TheVespap200e]

Love the Carnage! Thanks Zeth! 😀👍

[@centexan]

Harvest time keeps EVERYBODY busy!

[@llyodreeves4657]

Keep up the good work love watching you on KZbin god bless

[@kevinback2543]

That was a fun show to watch. Thank you

[@aprilgeneric8027]

10:15 find resting an air hammer needle on your pry bar and letting it rip to create vibration really does wonders in this situation. absolutely had deere double bearing set ups in compression tension pulleys the worst.

[@lawrencepevitts2434]

How many years have you been doing this? how much would you say you have invested in tools for your job? Excellent video as usual.

[@beckyumphrey2626]

He is a Snap On Man. Bet he has more money in tools.than many folks have in their home.

[@bigwrenchlewis2529]

From someone who has worked in the industry for 40 years if I could make a suggestion- lay a piece of cardboard behind the radiator core to protect it-things can go flying sometimes and I found cardboard lots cheaper than a core-for what its worth. Enjoy your videos very much.

[@chriscarter1177]

You and I think alot alike sir!

[@meateaterwhitetail7291]

Like what the land owner that use to till our fields with the 4455. The new stuff aren't quite as good as the old stuff. I really agree. 70s tractors are the shit compared to the new tractors. Today still running strong.

[@billcovert3473]

Popping out air cleaner = exhaust valve not opening, valve train failure. Just so you know old guys like your stuff. The old Cummins engines had a compression release for cold weather starting. The exhaust push tube had a collar at the center, which a shaft had cut outs to match the collars. Driver pulls a cable which operates a bell crank, which rotates shaft, which holds exhaust valve open, which allows engine to spin fast. The exhaust push tubes would break where the collar was. Hence popping thru air cleaner. Don't mean a thing today but let you know old timers enjoy your content.

[@WilliamVincik]

the zip ties on the spring is so useful for s;prings we have to fight, thanks for the so obvious solution we never thought of!!

[@ShainAndrews]

Finished the corn yesterday. Lost one bearing on a grain cart, otherwise no issues. Makes a guy understand why the red paint pays better. Oh and none of the equipment is new by any stretch.

[@jmazoso]

That's a sweet tool your dad made for you!

[@ZKMasterTech]

It sure is!

[@alisciamarotta3888]

👍

[@BRPFan]

Another great video, Thanks Zeth!

[@genechronister7085]

Another great vid! Keep the deere's running and stay safe

[@johnbucklerfarms]

Now I see why you can do the Big Hammer Challenge I think the Company needs 2 People on jobs like that for Protection from Workmen Comp injuries! Great Job Zeth!

[@alffred4021]

Schön, wieder ein neues, mega spannendes Video, danke 🇨🇭😇

[@CRice-ln8lm]

Did you remember to check if that fan drive input shaft was straight on this example? JD might balk at a new motor.

[@kerrygleeson4409]

Thanks for sharing Zeth always very interesting 🦘

[@GICK117]

Nice to see people who care about there finished product. Even though the product is green.

[@KALI1080]

13.5 with a broken valve bridge. I had to deal with one of those this spring in a 9560 RT. Broke the bridge and bent the valves. Pulled the head and there were 11 cracks between the valve seats so customer got a new head put on. Have you guys heard anything about timing gear idler PIP's on the 13.6L engines? We got our first one in the shop this week. How come we never see any sprayers on the channel? Is there just not that many out there in your area?

[@crandonborth]

A neighbor runs John Deere tractors, and he told me those 9560s and 70s motors are Junk. He ran both and both had valve train issues so he ended up selling it and buying at 9620RX with a Cummins in it… no issues yet.

[@RA-II]

Hey used to work on Aircraft and found I had to take off my rings and watch because they get caught on things and something it is tough to get your hand out or your finger. And you have a nice watch . Hate see it scratched

[@DougsHomestead]

My dad always started a bolt or nut and said, "Let it rest," after a struggle to line up something heavy 😂😂😂

[@cdalton3169]

I love your channel. Great content and fascinating! But I have to say that I don’t understand the percentage of failures on some of these Deeres. I have had two and had a lot of issues. We have since changed everything to Kubota over the years and we have absolutely zero issues with any of the equipment; excavators, tractors, etc. Just basic service… fluid changes, filters, etc. religiously follow the factory maintenance schedules. But nonetheless, love your skills, professionalism, and ingenuity! Keep the great vids coming!

[@stanbrow]

Cool custom wrench

[@PrairieMechanic]

I’ll never understand why Deere doesn’t just give up on the stupid variable fan. Either run a hydraulic fan or have direct drive or viscous. Any money you might save on efficiency is lost on repairs. This is the case on ALL JD models with variable speed fan. Especially s670 combines with the 9.0 where the idler gear is famous for coming off and grinding into the front cover. Brutal designs.

[@peterzweck1763]

Zeth certainly seems to spend a fair bit of time on fan drives...and replacing them with updated drives. It's good that Deere is continually improving their designs and offering upgrades to older machines...but it often seems they're using the customer to test their designs and them charging them to fix the problem if they fail. Good business model 🙂.

[@bm4751]

Gift that keeps giving.

[@mitchellunger9005]

Use fuel return tubes from a 4440 for that snap ring on the fan drive

[@beckyumphrey2626]

Hard to believe JD does not have detailed maintenance manuals to do these jobs the most efficient way possible. Does each mechanic in the field.just.figure it out?

[@BruceBergman]

Get Granny's Roaster Oven you use for heating bearings, and you can test the thermostats in hot water. In bulk. 🎉

[@RichardThompson-gc1cf]

Great time to pressure wash radiator with the fan out of the way

[@alanclark639]

Tell you what Zak - when I see a guy your build bending a long SnapOn bar - you don't have to stress the force! Again - good to see how John Deere have designed to make your life easier. How many hours on the 9529R? Has it had a hard life? Difficult to tell from my distance, when I see the paint job in almost showroom condition - I expect the engine to carry on at least till a bit of rust shows.

[@markhastie5427]

This was great to watch.

[@LucianoAcosta-z7h]

Buen día, como siempre de 10 tus vídeos, x favor subí más contenido..

[@lukegilliland8746]

Great video as always mate! love the vids all the way from Australia here! also just wondering if you had the part numbers of the john Deere engine barring over tools by and chance? Kindest regards :)

[@MarkTheTractorWhisperer]

It's great to see your techniques. Have you ever tryed pushing the Driven Shaft out with a Grease Gun?

[@wilsoninnz]

Wow, that's one the most complex fan drive systems I've seen. Why not have a straight hydraulic drive?

[@petereriksson1390]

Like the thinking of you and your father! A +++ fore that one Sir's! Best Regards Peter Eriksson Sweden Europe 😅😊😊!

[@supremecommander5229]

They actually make a "wrench extender"? At our shop we call that a pipe.

[@ShainAndrews]

Either buy an extender or make one. They work much better than a pipe.

[@DarrenBrezinski]

I am impressed with your attention to detail. Very good mechanic just can't believe Deeres low hour troubles. These things are money pits. I bought a 9630T and finding out the fan issues etc etc. $10,000 spent and climbing.

[@DarrenBrezinski]

12000 hrs on my 855 cummins and no water pump replacement yet. If it does fail it doesn't grenade an engine internally. The fan has fixed pulleys that travel one speed with a grease zerk for bearings. 12000 hrs and never been touched other than 3 sets of belts lol. This stuff Deere considers maintenance that's normal is BS. In a real world water pumps dont get replaced before they fail for fear of wrecking an engine.

[@ZKMasterTech]

Thanks 👍

[@garyriggins3354]

Wow such carnage.

[@timmywarren2349]

Very good Video 👍 👍

[@kellywilson8440]

That 9520 looks almost brand new , What would cause a knocking in the motor already ??? , Good video and subd !

[@trentfield6542]

I have 2 2014 9560Rs They are truly what nightmares are made of…… Put so much $$$$ into repairs think you can get one decent year out of them, and send down the road. Still have them. Cause me so much stress.

[@kevinalexander595]

Looks like the radiator needs a clean

[@travismaier4567]

You forgot to stop at the hideaway! Heard there is always fish there.

[@peterscheuer9118]

John Deere quality is going down. Glad i sold the stock.

[@badhop9035]

it took a mechanic 8 hours to change the alternator on my Kia Sorento and that was still easier than that fan drive. Man how do you do it?

[@bradley7723]

JD Quality has dramatically dropped over the last several years. One of my friends just had a rod go thru the block on a new deere with less then 50 hrs on it. Deere is fully warrantying every thing and free of charge tractor to use until his is repaired, but he said that may be the last green tractor he ever buys. I have a 1999 9300 thats been great since new but if i were to buy a new one it would most likely be red. Deere's prices have gone way up and quality has dropped way off.

[@bm4751]

Profit, should be for everyone, including the end user, whose profit only shows in long term reliability.

[@butchknapp8822]

Great content. Love that.

[@dsop66]

Woot woot!! First to see this video. Love these videos!!!

[@BruceBergman]

They can make a Spring compressor for that, zip ties can pop under that much tension and bad things can happen. To good mechanics... 7:20

[@Jacob-40]

Good job boys

[@ranmarks6739]

When you compromised the spring and put cable ties on it to get it out! Why wouldn't you compress the new one and put cable ties on it to give you more room to get the fan back in once the fan is in place cut the ties...

[@williamorman4779]

Zeth on a 8270r power shift you have to hold the clutch pedal smashed to the floor or it tells you the clutch is slipping, is this normal?

[@ZKMasterTech]

Needs a trans calibration probably

[@douglassellers7528]

I was disappointed. No big hammers used. Got another set of yellow racing wheels turning.

[@glowplug4762]

@16:26 And I thought Deere hated us marine guys!😬

[@stevedrane2364]

Very good thank you 👍👍 How many times do hit your head on the the rasied bonnet . . 🤣

[@darkhelmetlive]

Are those redundant thermostats or are they for different systems?

[@nickwhite6717]

Usually just for higher flow rates in a smallish housing. Isuzu runs 2 slightly different temp thermostats in 6hk1s to regulate temps better

[@anthonymeyer8615]

Why do they use that style fan drive? I’ve never seen that style on a heavy truck etc..

[@grahamjones4888]

Well done Sir, you can skip the trip to the gym! 🤣

[@nelsongilbert1695]

Dear John Deere design team... Please design a fan shroud that can be removed in sections. Suggestions... quadrant modules?

[@weyerhaeusertekfarms8402]

Just wondering why you didn’t put new water pump in with 4000 hours on the tractor you were right there just wondering?

[@mikehopkins03]

Can you do a video fully explaining the whole air conditioning system on a tractor?

[@mikehopkins03]

And explain what to look for when putting the gauges on the high side and low side

[@matains88]

Is it common to change water pumps as prophylaxis? I had one blow up at 2500 hours on my massey 4.4l and now i'm over 5000 hours. Maybe i should just replace it before it gives up?

[@tvboxtvbox2951]

I'm surprised that they don't wash equipment before putting it in for repairs.

[@savedbyJesus74]

It may run just a little cooler if they cleaned the radiator out ...lol

[@russellschneider4317]

Where did you get the belt gauge at

[@ZKMasterTech]

Through Deere parts

[@davidellenbaum1229]

how often do you flush fins on rad cooling package interval 500 hrs or less ?

What does this repair job cost ?

[@donaldberg7955]

Have u on several videos dealing with “fan drives”....the objective seems clear, pull air thru radiator, yet the fan system seems SO complex and complicated....WHY?...obviously a bigger objective for the fan...
