John Deere 8370R hydraulic diagnostics - This one ALMOST stumped me!

Very interesting approach to the topic! Thank you for such an informative video! 🔥😛

Another great video. Thankyou.

Great choice of topic! Thank you for the fascinating video! 🧡💖

DTAC lol

You had the trouble all mechanics have at one time or another in there career.i have had this issue where i could not get the thing to do what the customer complained about.

Good to see the case tractor is not broken!!!!!

Zeth before you completely go down the rabbit hole does the planter have a hyd fertilizer pump? If it is bypassing or the screw to adjust flow is backed all the way out it will be taking the steering away. Had this exact thing happen last year. Unhooked planter and tractor was fine.

Good time for rain crops are at perfect stage in growth.

👍👍👍

I need to join with you i am working in saudi arabia john deere dealer

Nice job 👏👏👏

Wow, what a nightmare .Great job, ZK MASTER TECH. Thanks for sharing 👍 Great video .untill next video ✌️🇺🇸

Orifice inside steering pump (on pressure line) could cause steering problem as well

Damn Son! Another oil in the coolant job! FeelsSadMan!

Good job troubleshooting and not just throwing parts at it. Be Safe!

Hola buenas tardes, como siempre muy bueno tus videos!!

As a maintenance technician sometimes I am scavenging for the root cause of the problem but every now and again I get lucky 🍀

Great job it's always the same tractor acts up call in the technicians suddenly tractor ok for them

ZK master tech with patience of Job God speed to brother love your channel 😅

Вы молодцы,какая неисправность была в Джон Дире ?

Alsome, love all of your content,

Great video thanks for sharing

I think the faucet can turn off now. Drought to flood in a year. It's always enjoyable to watch you work. With each job you have an opportunity to learn something, so the next time you run into something similar, you have a better idea of an approach. Each job adds something to the library. Thank you for the interesting video. Stay safe, and God bless.

Glad I got out of the trade before Hydraulics got so damn complicated, tying it all to the trans etc. Things were simpler in my day, except for combines of course. Thanks Zeth for taking tiny steps rather than big strides. Look forward to next video. From UK.

There’s a lot of hydraulic oil doing a lot of different jobs at the same time here Zeth. I understood your clear explanation of the respective components. If I was a rich farmer I would draw comfort that the Deere support network had people in it like you that know what they’re doing.
Enjoyable watch Zeth, thank you.

Hi zeth John from England another great video keep them coming watched every one 👍

In 1985 I wrote Caterpillars systems and diagnostics procedures for LSPC hydraulic systems to fully adjust margin pressure and relief pressure. Three of designed the Caterpillar differential pressure gauge group. If you work on LSPC systems get this gauge. It’ll save you a lot of headaches

Another awesome vid! Keep the deere's running!

Great video.

Nice Vid!

I have hydraulic problems on same tractor model on Brazil.. but here tools to test it's hard to get

I feel your pain installing the valve, almost thirty years working on forklifts I came across a few where removing parts to gain access took longer than removing the valve itself. Love the channel and its content 👍

Don’t you hate tight heavy parts

I love watching your videos, very good content, honestly it is wonderful to be able to see you and learn from all your work, thank you for your channel, happiness

I like the video's very much, it's one of the reasons i get case or fendt. 😮

Thanks for another awesome video ZK and Joseph.
It was extremely informative and interesting and enjoyable to watch.

Wow. This tractor gave you a run for its money. You had lots of testing to do and I know from watching you, you didn’t know exactly which way to go with this one. Appreciate the fact you gave the customer the benefit of replacing that valve body under warranty. Like you said, hard to say what the issue is because you never got it to fail. Agree with your decision to replace the valve body and go from there.

I give you a tip of the hat for fighting that new valve body back in there. What a struggle. So many lines to hook and rehook back up. And it appears to be doing ok now.

On to the combine for you and Joseph. He appears to work well with you. Thanks for teaching him.

Thanks for everything ZK. Really enjoy your videos. You are one of the best John Deere has sir!!!!!!!!!!!

Hang in there. Take care.

😊😊👍👋🇺🇸🇺🇸

I always like to watch a good troubleshooter. Thanks for bringing us along!

Why are the replacement parts not painted factory color?

Well done

Did this once on a 5r. Painful process

👍👍
