John Deere 8R 370 DEF tank level incorrect & Cab fan is noisy. Let’s tear into this new fancy cab!

Welcome to the first episode of ZK MasterTech shot in 4K. In this video, I tackle a DEF tank level issue and fix a noisy cab fan. These new 8R cabs have the HVAC system behind the seat instead of in the roof. We are going to tear into it for the first time together!

As a fellow man of large carriage, I was feeling your pain watching you work in that heat and humidity!

[@wildedog3967]

Seems to be a common problem with this particular component . At least the DEF headers you've replaced were not severely encased by the tractor . Mike Mitchell had to replace one on a brand new Fendt 1167 , it was over 4ft long and a nightmare to get to ! Keep up the good work .

[@allenmoore4186]

You forgot to say “keep that green iron moving” in your closing statement. Have a great weekend. Great video as always!

[@ZKMasterTech]

Sorry I'll do better....

[@TheVespap200e]

That new camera is getting it done. Way better sound also! Thanks for the upgrade! Zeth! Looking forward to future videos. 👍

[@TheGooj]

It's really nice that you find it valuable enough to invest in this project, where you're sharing the wisdom to us all. A whole lot of us might not be turning screws (or aiming for such career) but it's still interesting and welcomed knowledge. Tinkering is no bad habit, since it evolves you. Thanks!

[@cineminded]

The quality of sound and video is excellent . And once again a very well made and easy to watch video.

[@jimclary7309]

Zeth, another exceptional video, interesting when you're explaining how the repairs are going to be made and what caused the the failure. Keep the knowledge coming. Definitely look you up at the next one. Stay safe!

[@arzamumma1202]

Viewed 6-4-22 from Fairview Hts, Ill. 9 am Hi Zeth, Excellent video and audio. Always impressed with workmanship and knowledge, have a good weekend IF YOU CAN !!!

[@BRPFan]

Another great video Zeth! Wow Deere was thinking when they placed the cab fan motor assy! Looking forward to you next video. 👍

[@stevenwilliams7348]

Camera looks really good and the sound was good to changing that fan was so easy

[@gardnermiller6820]

Great video! The new camera works great, nice picture quality and the sound is much better! Thank you for your hard work.

I'll check out that little tool kit...thanks for sharing!

[@robertg.3555]

i enjoy your troubleshoot skills. you enjoy a challenge, plus learning the equipment. i had previously asked if you give field reports to J.D. but , after watching alot of your vids , i now realize you would be on the phone 8 hours a day !! Sloan seems to be an great company to work for.

Excellent content and yes Knipex makes the finest pliers on the planet.

[@jamesbane9121]

Sound and video are awesome!! Thnx for the content!!

[@stevenicoson6670]

Thanks for another great video ZK. It was interesting and enjoyable. Good job on the problems this 370 had. Appreciate the way you approach these issues and figure what the root of the issue is. The DEF tank problem was straight forward but was surprised at what came apart to get to the tank unit. Once apart you had it done in no time. Was interesting. Just feel this DEF stuff is so unneeded. Understand the theory behind it but just so unneeded and makes work for all of you. The fan motor was interesting. I would have struggled figuring out how to get to it without taking more loose than I needed too. You knew right away how to get at it for the fix. Nice work. Learned that one. Like your approach to the final thoughts on the codes. Like your words where you you said is senseless to throw parts at it and tear the cab apart. Never knew throwing parts at a problem worked very well. Like your approach ZK. Again a real good video and lots of teaching and instruction on fixing the issues. You take care and be safe. Looking forward to the next video. Thanks for everything. The Iowa farm boy Steve.

[@ZKMasterTech]

Thanks Steve!

[@westernstar4964]

I work on Cat equipment and those units fail so regularly that we had to keep them spare just to reduce downtime. The spare was used and a replacement was ordered and it was on backorder for months.

[@agoodneighborautorepair2176]

Another great video Zeth thanks for sharing 🇦🇺👍

[@Bryanja81]

Hey Zeke, they make a fan that wraps around your neck and blows up to keep you cool. I didn't know such a thing existed until my brothers wedding in Vegas last August. Yes, an outdoor wedding, in Vegas, in August. brilliant idea. Anyways, think it's available off Amazon.

Audio and video sound and look great. Nice choice.

[@lukedog7028]

Def system looks like mechanic job insurance forever

[@mikeclifton7778]

Very poor that the whole header has to be replaced, I suppose it's another way to get money out of the owner. I don't remember the DEF ( or AdBlue as it's known in the UK) having any odour to it. Another excellent video Zeth.

[@x400keganp]

Hello Zeth, really enjoying your videos! I wanted to give you some feedback on your new camera. The 4k video quality is excellent. Audio quality is good, except sometimes it sounds like it is under water or the mic is muffled. Not sure if it’s the camera or something in uploading after. Keep up the awesome work and really appreciate seeing you promote complex hands on career! 🍻

[@DaveG7920]

Enjoy your videos. Its a little concerning that many of the tractors you work on seem very new. Perhaps they're high hours? It seems a little overkill to have to replace that whole assembly for the DEF fault, they should really just make the sensors.

[@halwilliams1682]

Those sparrows sure wanted to give their opinion on your work.

[@wesleycooper2647]

Do you suppose they are Jack sparrows?

[@frasermathers2287]

Hi Zeth, excellent video as usual and loving the new camera quality. Over the months of watching all your videos one of the things that strikes me as one of your many qualities is your ability to remain calm and so focused on your tasks. I also feel that you are like this in all aspects of your life, so one question! What is your secret to the outstanding attitude you have towards your work and life in general? When I was younger I was a real hot head getting annoyed at the slightest thing (not so bad now I am old and retired). Thanks for all you do from a very sunny Scotland today.

[@ZKMasterTech]

You just don’t see the moments when I throw a wrench and cuss! Lol When it comes to wrenching on equipment, you’ve got to be patient. Getting mad or upset makes you lose focus and just takes you longer. I just take a step back, think about it for a minute, and keep moving forward. If you do see me throw a wrench, you might want to run lol. When I work on equipment, I treat it like it was my own and I’m very particular.

[@frasermathers2287]

@@ZKMasterTech Zeth, thanks for your reply and love that you treat it as if it were your own as that I how I ended up motivating myself too. I will also keep in mind your advice for when you do start throwing tools about 😁

[@ronomdalen3186]

Nice video and audio 👍

[@ryansukraw2399]

Did the tractor set any codes when the DEF levels are fluctuating that much? In other words, does it monitor the DEF level to make sure it is being used?

[@ZKMasterTech]

I guess not!

[@stevetrowbridge7101]

[@slypig24]

Your DEF fluid is called Ad Blue in Australia being 32.5% urea and 67.5% water. Is your DEF the same?

[@ZKMasterTech]

Yes 32.5% urea

[@mikekleinsasser8334]

Why so many problem with the def tank header on these new tractors?

[@nollz7085]

I've seen on the john deere Excavators with the code 3516-1 def concentration extremely low and its been simply fixed with a new header.....expensive little fix if off Warranty

[@certifiedwrenchpodcast]

I saw the fan going in backward right away and was like nooo!!!

[@ZKMasterTech]

It happens lol

[@ChristopherDenneySeedy]

Nice video, loving your content. You might to disable the auto focus, or fiddle with the depth of field on some of the shots with you moving in front as it kept focusing on the pattern of your shirt instead of the work area. :)

[@ZKMasterTech]

It’s a work in progress. I used that camera for the first time that day, performed all the work, and used a new editing program for the first time. I think it turned out well.

I was wondering if you have started using a scope for your diag?

[@richardlong9877]

So what’s the story with these knipex pliers. I’ve never heard of them before watching your videos. It looks like you use them in the place of open or boxed end wrenches at times. Are you not afraid that you will booger up the heads? What makes them so good? How do they compare to channel lock and other similar products?

I looked up the price of the def valve. Over $1000? The whole assembly is $1300. Seems crazy for a little valve to cost that much

[@ZKMasterTech]

Yeah they are pricey and hard to get.

[@bigcheese370]

Those tractors are the cats meow

[@jayfarmer3911]

You seem like a guy who appreciates a damn good and loud jam session. Do you happen to know what Deere changed on these new cabs as far as stereo components? I have an 8R and 8RT signature edition and the sound quality in them is terrible compared to the previous gen 8Rs. Both sound quality and volume. A guy could properly rock out in the older models. These new ones even on 30 do nothing for me. Did they change speakers or something else. This new cab as a whole is a pretty big let down. No storage, and cheap plastic everywhere. Not to mention the cheap feeling doors that remind me of the red tractors i used to run.

[@ZKMasterTech]

The new 8R’s I’ve been in the stereo is fantastic. Especially in the 8RX i was in had a subwoofer. It was banging

[@jayfarmer3911]

@@ZKMasterTech hop in them back to back. Both mine have the sub, all my older ones do also, but the older ones hit so much harder, and are way louder. Like make your ears bleed in a good way loud. Even with the tweeters in the cab posts they don't sound as good. Was just curious if you knew what the difference was if any in speaker components. Great info in these vids BTW.

[@ZKMasterTech]

Yeah i don’t know any specifics. Thanks

I’m guessing it must be one company that makes those DEF headers since they’re having the same problems in different colored tractors

[@conradward2945]

Why do JD use 18mm spanner bolt heads?

[@semperfi2507]

I have a 5100e and the level will show correct for about an hour maybe 2 then I get sensor fault code 3517.12which will turn into 5246.15 ! Please help I have another 5100e and thought I’ll just swap tanks so I removed it but when I went to throw it on the other 5100e the electrical connections are not The same ? Maybe cause it’s a couple years older ? Any way my question is once I replace the head do I need to program anything or is it just plug and play ? By replacing the head will this fix issue ? I also have replaced both the vent filter and the def filter under tractor ! What’s crazy is it will work fine for hours then it just non stop acts up ! I’ve replaced hydraulic pump radiator and never had issues but this def thing is so frustrating. Thank you for you help.

[@ZKMasterTech]

It's plug and play. Should fix your issue

@@ZKMasterTech thank you sir. Would you say that’s the issue ? I’m not tryin to hold you to it or blame you if it’s not But from your experience ?

Take an assortments of bolts, cut the heads off, slot the remaining stud. Use them to hang the heavy stuff on so you can get the other bolts installed.

If you use a hand hacksaw to slot the studs, double up the hacksaw blades to make a wider slot.
