8270R Priority valve failure - 8260R Idler Gear, turbo’s, & Dyno Run! Fan explosion 💥 8360R!

This video is packed full of John Deere fun! First I take a look at a 8270R that has hard steering which leads to a priority valve failure, then we jump into the 8260R that the engine idler gear came loose. Doing the best I can to band-aid that thing back together with limited parts and then I have to replace BOTH turbos…then I put the tractor on the dyno to see what it’s got and to make sure everything is good. Then I end up hauling an 8360R back to the shop because the fan went through the radiator.

I asked Andy Hourigan on his live stream couple days ago if he watches your channel. He said that he does, and he just watched your 640 video from a day or 2 earlier.

[@douglassellers7528]

Keep at it. Gotta keep those yellow racing wheels turning. Good job.

[@WrenchingWolf92]

Was watching this while on lunch in an automotive shop. I had to deal with a Die grinder, several half-inch impacts, an air buffer, and a pressure washer while trying to listen to a die grinder on your video. xD

[@russelldavies4943]

I see 3 missing one just below the thread love the channel 💪 awesome

[@jacklisiecki2389]

Solid episode. Amazing how those o-rings failed on the priority valve. Good work removing what you could. Must have been an expensive repair for 2 failed turbos - ouch! Thanks for interesting videos.

[@johnc6343]

why is that amazing? thats what happens to orings when they fail.

[@lounar482]

Another amazing job of diagnosing the prob and then knowing just what to do!

[@tomn7087]

Great job defining the problem and how to fix it. You sure make it look easy and we all know it's not.

[@williambryce8527]

This was a great video with lots of varied content! Great Job! But just watching you makes my old back hurt, I can remember how it felt!

Enjoy watching and learning keep them coming

Thanks Zeth , good educational stuff as ever.

I enjoy watching your videos I've always enjoyed growing up around tractor's

[@kerrygleeson4409]

Another very interesting video Zeth thanks for sharing your knowledge 🦘👍

[@williamorman4779]

Another great job zeth,

[@GNX157]

I was surprised to see JD doesn’t mandate replacement of the turbo oil feed lines when getting a new turbo.

[@nathansparrow1416]

Thank you , you are always very interesting . removing broken bolts is very satisfying !

[@frombryant6678]

Especally when you luck out & they come out easy. Ahhhh! The rusty ones that come out in pieces are a bit*ch!

[@MikeT]

It's always cool seeing all the different parts and systems. The Priority valve is pretty interesting. All the planes I work on have a landing gear priority valve. Kind of the same concept. When you put the landing gear up or down it makes sure the flight controls have enough pressure. If they don't it cuts of hydraulics to the landing gear. Better to have to go around because the gear isn't down than to not be able to climb out if their is terrain on final

[@timbo19751975]

My eyes are watering at the cost for 2 new turbo's on that engine at ~3000hrs :(

[@JDFIGHTER87]

i just got a new tractor and the first one with DEF. And it took half of the def fuel for on tank of diesel. The problem was, the nox sensor was broken. i just hope the src filter will be ok, cause it did make a lot of regenartion in the first 20 houers. great work mate! cheers from switzerland.

[@brianrutherford3681]

Glad to hear the 95 was not to bad.

[@buckinthetree1233]

I have several pair of locking hemostats used by doctors. I really like using them to extract o-rings inside of bores. The next time you get some stitches, ask the doctor if you can have the tools that he used. Most of the time they will give them to you. Even though they are nice stainless steel they disposed of rather than sterilized and reused. I have had one or two goofy doctors tell me no, because they don't want people stitching themselves up at home.

[@planeiron241]

the 8360 the op couldn't feel the vibs, that's crazy I mean they should have felt something was wrong before the plunge, but💩happens ok I've wrecked crap to, greAt vid👍👍👍👍

[@mikepierce3262]

I just changed one of those yesterday lol that’s funny so that is called a priority valve

[@ronaldblue8713]

Interesting video. DPF and DEF systems are a common issue in every brand of equipment it seems. Had a Cat backhoe plugged so badly it wouldn't start until the exhaust was broke loose.

[@conradbolton9232]

My steering got ropey 8335R and I changed those priority valve O rings. Nice cheap easy fix. The dearest part was that big socket...

[@stevenicoson6670]

Thanks for another great video Zach. Busy busy time of the year for you. Wow. The repairs in this video were once again super interesting. When those turbos go they go. Wow. Never seen oil in them like that before. The situation you had with the power steering was interesting. Did not totally understand that the hydraulic priorities worked like that where the steering and such has priorities over the other systems. Not a bad fix once you figured out what was wrong. Learned a lot on that one. The tractor where the fan mechanics took out the radiator and other parts was a big fix. Nice you have a tractor the farmer can use because now is busy busy time. Have not seen any planters you have worked on. I am hearing lots and lots of sensor problems. For example, Zach Johnson, has had a ton of sensor problems. I hear that same story at the coffee stop. Are these planter sensors that sensitive to what ever, like the weather or whatever. I hear some talk about the grounding of the sensors????? How about a quick overview of planter sensors. You take care and be safe. Looking forward to the next video. Thanks for your great teaching abilities and narratives explaining these problems and fixes. Thanks for everything ZK. The Iowa farm boy. Steve.

[@ZKMasterTech]

Yeah sometimes those planter sensors, especially the down force sensor can be a pain. And sometimes you can’t get them to act up until you start planting. Hard to find those problems in the shed during the winter. We usually get the bugs out of them when they first start planting and then they are usually trouble free

[@johnmorgan4017]

Lots or good stuff going on there!

Frost King A/C conditioner coil foaming cleaner works amazingly well on radiators. Give it a try!

Ouch.Seems like a lot of work to be doing for only 3000 hours. Wouldn't wanna see that bill.

[@popswrench2]

watts $10G work for a GREEN owners ??? tune up

[@matteo692]

Good video ! Turbo Hours ? 8335r turbo vgt = . Turbo normal on tre right is ok !

[@jkel2080]

Am I the only one who finds themselves trying to look around the tv to see in the hole?

[@jacobotes8443]

Man looks like that fan drives on them deeres are a crappy bunch. Pretty happy with the claas we run at work only problem so far was/is a electrical issue causing a common rail pressure relief valve code derating the tractor. As far as we can tell there is nothing actually wrong just some electric issue but we dont have a mastertech who can manage to find it...

[@johnflynn9756]

I can only imagine what these repair costs might be. No wonder inflation is high.

[@daniel_poore]

Wait, whoa.... you guys have a tractor dyno at your shop!?!

[@robk9827]

Matt good morning. Im a auto tech at a dealer. Just wanted to find out on how ur payed. Are u payed salary or peace work. I also was a roadside tech for bmw and mb so when I went out I was paid a flat fee. Thanks for your videos love them.

[@2xKTfc]

Fantastic video! And a question: When mechanics say they'll "send a part (like an engine or transmission) in 'as a core'", what does that mean? Is that going to the OEM for a factory reman/repair, going to be pulled apart by a QC engineer to see what went wrong? Or something else? Cheers!

[@ZKMasterTech]

They get sent back to Deere reman to be rebuilt

[@2xKTfc]

@@ZKMasterTech Thank you! :)

[@johndenoma6397]

I retired from farming in 1986. My last tactor was a 8640and 7700 combines. What does a job like this cost the farmer? Do you get most of your replacement par as remanufactured from Deere?

[@mfc4591]

Fan hits the paw paw..........

[@littlesteve855]

Will that turbo fit my Civic?

[@luisnunes7933]

Hello! That's a biturbo expense...

[@lepe7797]

I got a 2012 8235r Oil consumption and white smoke out of exhaust,(deleted) I got play in my vgt turbo shaft. Would you recommend replacing both turbos? Or start digging into the rings? Compression test came out good just a piston was shy by .4 , they did have a recall for rings. Would it be worth the shot with turbos?

[@ZKMasterTech]

I’d take the pipes off and see if there’s oil in them first.

[@lepe7797]

Appreciate it sir! Great fan !

[@beaudostal5693]

Was the field cruise on dropping your horsepower?

[@ZKMasterTech]

No i had full rpm.

[@mitchellunger9005]

Did you shut the field cruise off when it was on the dyno? That might of been why it was low on hp.

[@ZKMasterTech]

You think a guy like me is going to forget that?

[@mitchellunger9005]

@@ZKMasterTech I seen the check mark on the screen and just wondered

[@ZKMasterTech]

2150 is the Max rpm.

[@dafarmer3721]

I’ve got a 2013 8335RT and whenever I run the hydraulics for an extended period of time and shut it off and try to restart it it will not start I wait a bit and then it’ll start. Also I’m getting codes that my scv are not returning to neutral position could this be a priority valve issue?

[@JaceJackson]

We have a 8335R and it absolutely will not turn on asphalt. Doesn’t matter how slow or how fast I’m going it just will not do it. It steers perfectly fine on dirt, I can basically turn it full lock while standing still on dirt. Does this sound like a priority valve to you? I have not tried engaging an scv to see if it makes a difference. Basically feels like I lost all steering completely the second I touch asphalt.

[@ZKMasterTech]

It’s worth a look.

[@grenmastermike]

What is a turbo dosing injector?

[@ZKMasterTech]

It’s the fuel dosing injector for the aftertreatment system.

[@popswrench2]

VGT seems heavy ... 2.2lbs / Kg

[@brianrutherford3681]

Why could you on rebuild both the turbos? I would think it would save your customer some money?

[@ZKMasterTech]

You can’t get parts for them.

[@brianrutherford3681]

Ok I thought like the ones in semi trucks you could rebuild them.

[@johnmilburn5715]

Would love to have heard the big Cummins without the can!🙉🙉👍

[@ZKMasterTech]

It was sweet!

John Deere uses Cummins on there bigger tractors
