John Deere 35D Excavator: Replacing Hydraulic Oil & Filters / Coolant Drain & Fill 

This is going to be the best maintained mini-ex on the market. Even better than "dealer maintained".

Satisfying series to watch; speed-up editing made sense. Now Mrs O can start her side hustle of septic tank maintenance, repair, and service! 😂

Free tip Friday. If anyone ever has to pour from a bucket like Eric did, put the spout at the top (12 o'clock) and it won't chug like that and it will come out smooth. It feels unnatural to have it like that, but it works. It's a little more challenging to get the initial liquid into the hole if smaller, but once you do it is great and much faster.

Now remember, many of us want to watch you dig the tree stump. Thanks, Eric, great series. And, hello from Florida. Now a constitutional carry state.

Well done. Remember that on occasion, according to Andrew Camarada, things will break for "no reason". Be prepared! 😀

Eric that machine will think all its birthdays have come at once , great job

Nothing better then doing all the maintenance right after you buy new Equipment to make sure you know it's done Eric O - After Hours

The previous owner may have bought that hydraulic filters and all the other service parts when he bought the machine back in 2012 and stored them until he got to 2000hrs but changed the engine oil and filters more often than the hydraulic filters maybe.

Nice video. I see the neighbor took care of the problem on the homestead, but the solution required bringing the mini excavator home and testing it out. 😜🤣🤣

A very nicely done series' Eric!! I do this with everything mechanical that I buy. My wife thinks I'm crazy but I am the 2 nd owner of a 1958 IH 330 utility tractor that runs like a top. The paint don't look good but mechanically she is perfect. Can't wait for the test dig episode and keep on doing the right thing.

I like the “ factory install wood block” to help hold down the battery!!! 😂. I always enjoy working on projects that the previous owner reinvented factory parts.

Can't wait to see this machine in action! I'm jealous, now I want one!👍

Nice job 👍. This JD is going to appreciate the new owner!

I really enjoyed this series. Looking fwd to seeing it action! Looks a neat machine.

Nice to know that you have a baseline and know exactly where your maintenance is. Good luck with it, Eric!

This is cool 😎! Hope you show us you operating it. 😊 thanks for taking us along!

loving this mini series!

Thank you for sharing. Your attention to detail is inspiring. There’s not many people in this world that care as much as you do.

What a great toy! Love all these maintenance videos on your new 35d excavator. You've done all maintenance spot on! Enjoy...

Man after my own heart key to keeping something working is maintaining it! Great Job!

New Toys! Dig up that Stump now! Cheers, Eric from Colorado!

I think that’s one of the coolest toys ever, Mrs O and the kids on a day at the beach, Wow. 😃👍

Always excited when taking care of a new toy.

The way JD trained me to do it, was to let the Hydro system sit for several hrs after a drain and fill after moving implements around, to be sure aeration has settled b4 topping off the system.

You look very cool sitting in that machine. I bet you would look even cooler in one of those big ones they use on gold rush. Looking forward to seeing some vids of you putting the deere to work.

The way you say, “Contact” at 5:00 made me literally laugh out loud. While I don’t have anything close to this and likely never will, this was a very entertaining video and appreciate all of your content!!

As a Retired Operator You make me Proud about TLC for Equipment Super Job

Excellent, I know you were really itching to use it for work!

im so glad that your showing this. Ive heard of to many ding dongs that by a premade lawn mower or generator take them home and fire them up and theres no oil in them and burn up the engine. ding dongs.

We have the john deere hand pump that attaches to their 5 gallon buckets for topping off our farm tractor. Works pretty decent...

Engine/motor sounds really good even through the internet !

Good job on the fluid change, when I do the hydraulic filter on my skid steer after pulling it I use a clean rag with a strong magnet wrapped up in it before wiping the bottom of reservoir if there’s any metal in the bottom it will get it.

Thanks for sharing Eric.

I'm looking forward for the videos coming to show how much easier it is to remove engines with this new tool

sweet maintenance video

I usually pour the oil in through the filter caps in stead of through the fill cap just like you do!

Good looking dirt !

Not sure why I am watching this as in my future no mini excavator is in site,,,,,but watching you wrench on something you are definitely not sure of is entertaining

Next is doing some work with it. I can't wait to watch.

It appears to be in pretty good condition for the hours. It looks like it may have sat for a while, too. If that's alge in the fuel, you'll need to treat that before it becomes an issue.

I cant wait to see what building projects you have in mind using your new equipment on Eric O After Hours!

I am totally envious

Mr. O, hope the neighbor took care of the intruder on your property. Now, I know why you purchased the 35D. Great for digging holes for the bodies. 😂😂 Great vids on doing the maintenance. 😊👍

Those little Hitachi build machines are very good and that's low hours. With your care she will last you a long time

Nothing like the smell of hydraulic fluid in the afternoon. I miss my life on the farm.

Hi, Mr. O. The main takeaway I got from this is that I respect John Deere more than before. I had seen some bad press. I think that the John Deere designs are better than average. I can see why the company suggests that people use John Deer parts. Any company would do that of course, but I see some justification here. I hope, without any justification, that John Deere is not gouging its customers. Thanks for sharing! Stay Healthy!

Cool. Water flows sideways!!❤😂😊

Great video as always super entertaining @Eric O - After Hours

Job well done... 🙂

Damn,,, I just knew when you said you were taking it home you meant my home ----then you said taking it to your home ---drats---. Oh well this will be fun to watch. You better record the antics old man !!!!!

That's a good running lil beast! I suspect the filter WAS changed... New-Old Stock. If he bought it new, he may have bought the service kit at the time he bought the machine. Your NEW filter is 2 years old... ;)

It's nice to have good neighbors

Eric! love the After hours videos....!

Great video. Just and FYI. The leftover hydraulic fluid left in the bucket. Get rid of it. Where I work we have critical hydraulics and the manufacture of the hydraulic components warns us on using hydraulic fluid that has been exposed to the elements and stored. They recommend either not filling until you use the entire contents or dispose of any fluid that is remaining in the container. I am not sure the sensitivity of the hydraulic components of a John Deere mini excavator, but might be safe than sorry. Just a Free Friday Tip. 😁✌

I want one... thx for the video sir

Great videos bud. Thanks for all the helpful knowledge 👍🏻

These are the things we do with every used purchase...go through and change all of the filters and fluids, inspect and lube as needed. Original factory filters ! More evidence the seller was full of hot air. I wouldn't bet on no sir, "is there anything you need to know" before using it since the seller has been wrong about much this far. I'd hope the seller was as loose with the sales price as he was with words about the service and maintenance cycles "he had performed".

Suction filter is always like that, it was set up correctly. The factory glues the oring in, normally its a white glue. Normal service on the suction screen is 4000hrs, if oil sampling is used and Hyd oil is extended drain. 2000hrs on the main hyd filter or 1000hr if Hydraulic hammers are used.

I can only imagine Deere John branded hydraulic oil ain't cheap, our industrial parts store sells a rebranded Chevron AW46 I forget the cost per pail. The most important hydraulic filter is the pilot filter it can cause you a whole lot of ass aches. Its the only filter in the hydraulic system that is pressurized hence its in a bomb proof canister. Hydraulic oil contamination usually comes from attachments like rock hammers or brush mowers.

very interesting thanks

Great Tool. !!!!

We want to see you working with it Thanks

This clunky old diesel sounds better than half the cars you got on camera in your shop

Maintenance is cheap in the long run. People don't want to spend the big money on fluids and filters but it pays for itself, keeps the machine healthy. I use OEM filters and fluids whenever possible

New old stock. Good on you 😝

Éric O is playing with his new toy, all he needs is a big sandbox. 😊😊😊

Refrain from calling the guy a liar right off, your proof is only proof that he purchased the filters in the year he purchased the machine as I did when I purchased my LT3800 and it was years before I reached my first service interval. The both the filters looks clean so why doubt that he did what he said? Be better than that is all I’m saying, God Bless and have a great day.

May want to check the pattern changer lever to make sure it moves freely.

If it's not too late, while the machine is clean... take a wire wheel and go over the underside and clean up the rust, apply paint etc. The machine will then be just about as good as new and will pretty much stay that way .

In my dreams I own a mini Excavator under 8,000 pounds, with a cab, AC, heat and a hydraulic thumb. Not for another tool to service, but to put to work around my acreage. 😎

nice one 👍

You’re way too excited about this! Lol. You deserve it. Thank you.

Afternoon Eric

Dude you are a stickler for measuring like me. I'm guilty because of being a machinist for 30 years.😂

Be sure to put any extra JD hydraulic fluid in a vault for safe keeping

If you put a switch on that back up alarm your neighbors will appreciate it. After you get some practice in it you can try the egg challenge.

now we need some holes in the ground put in a koi pond or a secret underground bunker or something LOL

Such a smooth operator…..I forgot the rest of the lyrics

Little advice running trackhoe slow and steady equals fast

Eric dont forget the final drive gear oil.

Anyone else hear Eric go,”Wee” as he was spinning around in the cab? 😂

I would imagine that rod was intended to be attached to the cap rod through the hole with a nut on each side. This would seem the logical setup.

As 'ole Scotty says, "oil is cheap, engines are expensive". Same for filters.

Another fantastic video also where do you get those Pink/Red rags Peace and love from Clearwater Florida

Like a good neighbor, stay over there.......

Over worked means eric o will be back with another video😅 Nice unit Lets see this machine rip that stump Once and only once..... Cheers

So I wanted to have some coolant on hand for a Deere 3039R, just for topping off if needed. Checked the manual. It says use "Cool-Gard II" or "Cool-Gard II PG". Way below that it says "Avoid Damage! Don't mix ethylene glycol and propylene glycol coolants." Does the manual say what coolant the tractor comes with? Nope, cause that would be useful information. Call the dealer; after they CHECK, answer is "ethylene glycol". (BTW - these videos are very useful for that tractor as well. This are the first videos I've seen where someone actually recorded changing the fuel filters, re-priming the fuel system, etc. start to finish.)

Well done son !!!😀😀😀

Check the bucket pin it might need some shims

Well well i guess you can never trust a used John Deere salesman lol 😆

16:20 it’s just new old stock! Maybe he got all the filters when he bought the machine and sat on them till service….😊

If you want to talk about expensive hydraulic fluid, Skydrol LD4 which is for commercial aircraft is around $9700 for a 55 gallon drum.

Many years ago in Egypt I was told they had no word or expression for maintenance, just broken or repaired. That was a local that told me, so who knows for sure.

I have had a radiator cap fail on the negative side. Had to be one of the only times a radiator cap kicked my butt...it would not come off for anything.

You know Eric, I do the same thing to all my "new" to me old cars that I buy. Change ALL fluids & filters. Even did it on my 2017 "Certified" Chevy Silverado that I bought with 30k miles on it. Also did it on the used John Deere E120 mower with only 40 hours on it. You got to start with a clean blank sheet, Right? I think I enjoy doing it as much as you do. :>) Greetings from that Old Jarhead in WNC

Would definitely set the valve lash in the head @ this point, very surprised if the suggested interval is as high as 2,000 hours.❓Happy excavating 🗽🇺🇸🙈 Small bites to start, it is possible to bend a cylinder rod when exerting max force, w/ cylinder rod fully extended. 👌

When factory sets the rods they are set for OEM fiters

When you change the coolant, should you blow air pressure into the radiator at the cap to try and evacuate as much of the standing coolant as possible?

To bad you didnt pull oil samples and send them out to a lab. Being you didnt know the history of the machine and have a video of the results. Good service video

That's Y WE LOVE U
