John Deere 35D Excavator: Engine Oil & Filter / Fuel Filters / Air Filters - Replacement 

This is the site I use to look up my parts using the serial number on the machine: www.deere.com/en/parts-and-service/parts/

Ah yes, I have fond memories of Grandma Davis riding her excavator into town on Sundays. She'd always bring back donuts and the lovely smell of diesel.

You should definitely consider changing the hydraulic fluid and hydraulic fluid filters, fluid breakdown and contamination are one of the most common issues with equipment.

That machine would be useful around the house. Who wouldn’t want one of these?👍

I REALLY love that you and Ray watch each other!!!! I, being a trucker's wife, know that there is an additive that will get rid of the algae in the fuel tank. It's very common now-a-days to have algae, I'm told, because of no more hot fuel return to the tanks. Hot return used to keep us from gelling up so quickly in winter, and also killed off the algae. I swear all this pollution control is more problems than it's worth. Want to gasp? Check out the price on a new DPF. (Diesel Particulate Filter)

Eric my boy, tell us a story, sometime about when you were young and you did something when working with your dad or someone that causes you to be so non-invesingatavite today. You destroyed something and your dad boxed your ears. The diesel fuel filter cleaning laid it all out there. I grew up in a gas station tire shop and you always put a smile on an old face. You do good work, keep it up, love you

When I rebuilt my wife's Subaru engine, I used all the Subaru parts I could get. It cost a small fortune, but I think it was worth it. One part I did purchase was the oil filter from Subaru thinking it would be a quality filter. I cut it open after I did the initial break-in oil change, and the filter was the same design and quality as a frame oil filter. I use Wix on the car now because they seem to be well made after inspecting them during oil changes. Sometimes you don't always get what you pay for.

I operated a 35 D for several years, put over 5000 hours on it with no issues. Great machine very versatile.

Those small “D” series excavators with yanmar engines are excellent pieces of equipment. In my opinion, the 35 is the most useful size for a property owner, easy to tow, big enough to do some work. Check the rollers, they cowbell pretty frequently. Don’t over tighten the rubber tracks, and keep it greased and it will last a long, long time with few to no headaches.

I put an old piece of window screen over the air intake there on the right of the engine door. Attached it with magnets. I have to wipe that screen off every few hours. Really saves the air filter and junk in the radiator and condenser. Love the show Mr O!!

I felt the need to wipe my face when you splashed diesel fuel on the camera lens when draining the fuel tank.

Can't wait to see your new machine in action. Congrats on new tool!

Holy moly, It's been so long I forgot this channel even existed!

"How many lights does this guy need?" ALL of them 😎 Keep an eye on that rubber air cleaner drain. They will get stiff over time, and not close up , even when the engine is running full throttle.We just replaced one on the neighbors 4440 tractor(10,000 hours and never been wrenched on) that has probably been sucking dirty air for years.

Thank you Eric. Enjoy all of your videos

Thats awesome! A new toy for the boys to help dad! Lol. Thanks for sharing. Love from AZ❤

Saw this sitting in your lot during the Silverado fix and was hoping you would be doing a video on it. Thanks, Eric.

New area for SMA garage I enjoyed watching the video. Can't wait for the next one

Hi Eric, the black sludge is probably diesel bug. It can really clog and ruin your system. It lives in the diesel water interface and the black is its excrement. You have to treat your fuel to kill it. Very common on plant and boats.

Excited to watch the series!

You can never belive when a previous owner says all maintenance was done unless there is paper proof and tons of receipts I always do the maintenance right after I buy equipment or vehicles I agree with you 💯 Eric O @After Hours With Eric O.

Nice Eric, thanks sharing with us, really enjoyed.

I really do appreciate your candor when introducing an endeavor that is unfamiliar... and as always appreciate the thoughtful approach with whatever you do.

I worked for a JD dealer 30 years, just retired , great little machine

Superb. Unexpected appearance of Brake Klean a bonus.

Eric, the specs on that seem perfect for a gentleman farmer with some land. 👍 PS: More after hours please. You do great videos.

Eric used to work on diesel trucks so no real challenge with this. Way more fun to work on when it's your own new toy !

Nice buy Eric, even has a installed Thumb .🤟 im a dealer TECH that Yanmar will go forever. Keep up with your maintenance 2000 hours. Hydraulics and a valve adjustment are due.

Sunday bonus video! Looking forward to a excavation video now.

I'm green with envy!!! Great machine! Congrats!

Great video Eric, Thanks for sharing!

I love watching you work on other stuff. I'll probably never have to maintain Grandma's excavator but now I know how.

Make sure to do the final drive oil Mr. O. Thanks for all you do n keep up the good work😊

Final drive gear oil would be an important thing to check. They don’t hold a lot of oil but are expensive to repair if they fail

Paint looks nice!

K&N, Amsoil cult and you wonder way some of us SO enjoy your channel you never disappoint.

Always servicing a recent purchase is a good idea for many reasons….smart fella

Pretty serviceable by any general owner. Love hearing about the owners story. Claimed all JD parts, well proof in the pudding. Love to see a video on your first project.

Great machine, lots of luck

I always like when someone gets something new to them. 🇺🇸 It’s time for maintenance having a manufacturer manual and knowing how to read it is priceless⚠️ Funny note RU-vid commercial in the middle of it he video was for bourbon whiskey how fitting Mr.’O’ 😊

You’ll have so much fun with that gem.

I have a similar machine. Very powerful and useful. Perfect size for hobby farms.

Awesome thanks Eric If it’s mechanical we can fix it. Looking forward to you operating it.

"I'm not a heavy wheel mechanic or a equipment mechanic ..." that's why I'm here. Love your content and your attitude. Just like hanging out with a buddy and a beer.

That's going to make changing Cadillac engines easier 🙂 Stay safe out there.

Ur the best mechanic for this if u do cars and trucks u can fix anything

It's a clean machine. I hope you have many happy hours with it. I'll check out the second video later.

Always enjoy the after hours / outdoor content. Might change the hydraulic fluid and check the filters too if you get a chance.

Oh man Eric heck yeah this channel is like a super fine dinning meal. It’s that good. 😘. Thanks for the video

I'm the same when it comes to buying something used. I like to sleep at night. The machine looks pretty clean overall. Have fun with it!

Best thing for you diesel treatment is add Powerservice additive cleaner,but you have to make sure the water is gone first! I service all of our Pisten Bully groomers with it.They are fine now,not to mention the regular Power Service additive has slick diesel in it!

Good video. I did all the service maintenance on my 2006 New Holland hydrostat 4x4 tractor Friday (1297 hours) with the grandsons help, cost a few pennies, lol, but well worth it. Purchased it New in 2006 and with regular maintenance they last a long time. Looking forward to the rest of the videos. ✌🏻

Thank you I was hoping we were going to get to see a video on it.

I bought a bobcat 335 mini excavator after I bought 10 acres of land. It was far less expensive for me to own it rather than rent it. I've had my mini for 4 years now and its worth its weight in gold. I was very green at operating it at first, but seat time has helped. I feel that I can operate it fairly smoothly now. Once you get comfortable with it, seat time will get you better at it. Nice purchase, Eric! Lots of luck with it!!

Great video Eric and I loved the content..after hours 👍🏻👍🏻👍🏻

Congratulations on that JD mini ex.This serviceable parts on this is a lot like my old 4300 JD tractor. I serviced it every year but the only time that inner breather filter got changed was every 5 yrs, and it looked like new then but I changed it anyway. Hope it serves you well.

I rented one about 2 years ago. Actually won a day's use at a fund raiser. They delivered on Friday and picked it up Monday morning. Took this rookie operator 2 days to do half days work. Was free so no big deal. Got my chore done, destroyed nothing, so all was well. They are a very handy.

Awesome.... I wish I had one of those for my back yard!!!!

Eric, just seen this very cool video you made on the 2012 John Deere 35D. Great to see you branching out, or maybe I should have said digging out. lol Very nice looking unit, she cleaned up great. Can't wait to see her working at your home base.

Enjoyed watching this one Eric. Hopefully, you'll get lots of good hours on this!

Well I learned something about my John Deere Tractor that I'd forgotten all about. And that was the floaty bit in the water seperator floated on water if present. The 35D and my JD 3120 tractor both have 29hp Yanmars so watching your maintenance was very familiar to me.

What a fun lookin little Tonka Toy. 👍

Subscribed to your new channel ... can never have too much "SMA" !!! Congrats on your new purchase and know I had the same issue with "Algae" in my Aluminum fuel tanks on my "Russian Gunboat" ... not fun clearing the carb jets in a rolling Sea !!! Highly recommend using a treatment chemical to get it completely out of you fuel system: "What will dissolve algae in diesel fuel? A diesel fuel biocide. This dual-phased (effective in both diesel fuel and water) biocide kills microbes in fuel, including bacteria and fungus. Use this product to rid your fuel system of microbial contamination."

Somehow after dinner, I treat myself to a DIY excavator video that will never perform. Heck you could work on a lawnmower and it would be entertaining. As always great vid Mr. O!!

Another fine video. It looked like the guy had the hours and date of service on the oil filter. Probably wasn't fibben. Have fun and go out and dig a nice deep deep hole. Threaten the kiddo's and they will never talk back. Enjoy!!!!!!!

Hey man iv watched hundreds of hours of ur videos so when I saw u working g on a 35d which is up my alley I was glad but if servicing a mini excavator i cant believe u forgot grease, cabin filters, and very important changing oil in final drives!!!!!!!

Very nice machine, perfect size

A new used excavator just in time for gardening season! +1 Like

Good video as always @After Hours With Eric O.

I did the same when I bought my second hand Takeuchi, also changed the hydraulic oil and filters. Don't forget to change the final drive oil Eric.

...still bustin' on Matt!!!!! 😂Love it Eric.

Hi, Mr. O. This is my first visit to this channel. I have subscribed already, just based on your previous detective work. I like your first machine to get personally. Thanks for sharing! Stay Healthy!

Excellent choice of machinery mr.eric. the only recommendations I could give you on servicing your machine is to prefilled your fuel filter (the screw on one) LESS chance of getting air into the into the system. Otherwise another fine job done by the man himself and remember if I can do it so can you! CHEERS!!! o-ya and remember practice makes perfect when operating your machine, be safe!!

I had a 2007 35D and it was a great little machine. It was like new when I bought it and knew the owner. Put 3000 hrs on it and performed all the service over the years. Replaced the tracks in 2018. Traded it in for a larger machine (Yanmar VIO-55-4) in 2020. The pricing for John Deere equipment had become insane. The only minor issue I had was a few hydraulic lines that chafed at the pivot point between main boom and dipperstick, but that is not uncommon.

At least you don't need to worry about where to put the flashlights, it's all metal lol, I always go through anything that I buy used, just as you were saying and these machines are fun to learn, working on and using them, have fun, my guy.

I saw that in one of your recent vids. Was curious what that was about. Now I know... Cool!

I was going to tell ya that there should be an inner air filter for that machine, then you figured it out on your own, good job bud!

Looks very good

I did the same bonding with my bobcat T300. Then spent a lot of money fixing the worn parts. Still a few more to do this summer.

Really interesting video.

Make sure you establish where all your zerk fittings are & grease them more often than one might think. Idk if you have an electric grease gun but they're a nice upgrade. Also change your cabin filters if you have a/c etc. Congrats on your 'boat' purchase. 😀

Cool video!!

I am soooo jealous on the excavator acquisition!!!!😢

Get a little glass jelly type jar, (DO NOT get a plastic one, don't ask, just don't) Wrap it in tape (in case you drop it) It makes a nice catch for your fuel filter when you drain it. That crap in the filter happens when it sits for a while. it IS a form of algae. There are bacteria that can form in old diesel. Some diesel treatment might help it can clean out the injectors which will invariably clog with that junk, I use the Amsoil diesel treatment, but they are all pretty good. Oh yea, watch the gasket on the fuel filter drain. They can crack and will leak like a mother. Get a bunch of extras and have them handy. Same for the fuel filter. Have a spare handy. Baldwin filters tend to be a bit smaller than their OEM counterparts. They used to be good filters, but lately I'm having my doubts about them. Always keep a spare air filter handy, too. I don't know about the Deere diesels, but some smaller motors get really finicky about how much air they can suck in. don't trust the gauge. They don't always work. 10 years of owning a land rover 90 I learned plenty of diesel engines. mostly the hard way.

Man that thing runs sweet I want one

I think the most important tool to have is the repair manuals and I always buy one for every vehicle I buy. Even the new vehicles.

ANOTHER GREAT VIDEO ERIC O

I have always did the same as soon as i bought an old truck or car over the years, clean the oil and gunk off the engine and underneath ,change all the fluids, check and or change the hoses and belts and usually also installed new shocks all the way around

eric that's a nice little excavator be nice to it and it will last well past 5000 hours, grease ALL fittings every 40-50 hours and boom dipstick and bucket daily, bucket twice a day for best life, I have been an operator for 45 years

Well, I've watched an awful lot of C&C Equipment and their deep love affair with John Deere - I've been a Kubota man over here in the U.K. for minis, I've had a few and even though now retired I still have a KX36a which I've driven into the ground (literally) which I bought new in 2002 (now up on blocks for a refit) also have a 2007 008 very mini with only 300 hours on it - still stiff to drive. Your purchase looks an excellent buy - folk who bother to write the hours on the filters have usually done the work - the coachwork on yours looks near pristine! Mine suffered badly from being regularly bushwacked when landscape clearing which could've done with a bigger machine but then there's the transport issue. I'll enjoy watching the rest of your videos on this!

Little helpful hit. If you plan on keeping the equipment for years to come. Keep any and all extra parts you might buy. Seeing how things are going in the world it will benefit you in the long run to keep stuff on the shelf.

It looks like a nice machine Eric!

I was so happy to see that you had the inner air filter!!👍 Great video, thanks!!

🙃yesss right on ,did not know about this channel, kinda stumbled on it here ,very much love your other channel, looking forward to watching here now 👍👌✋️☝️

The slightly stubborn oil filter reminds me... When my mother passed away some years ago my sister and I was confused to why there wasso many oil filter tools in our father's toolbox. Thing is that while he was an engineer on jet engines he didn't touch the maintenance on his own cars - that should be done by people trained by the manufacturer and have access to the factory information - he thought mechanics at dealers worked to his aircraft level of procedures... (Once when I took his car to service he wanted them to clean the engine bay, they refused since it was to clean!) Anyway, we couldn't understand why he had more or less every style of filter loosener. Then it hit us, mom had problem with lids on jars due to pain in her hands, the tools were likely bought in attempts to find something that helped her with those. Sadly since they all where in the basement none likely worked good enough (or she refused preferring to ask for help).

Might want to put some biocide in the diesel. No doubt there are plenty of options so you can pick your poison. My personal preference is FPPF KillEm Biocide... mainly because of the violent nature of the name! Enjoyed the content, thanks for posting.

South Main Excavating. Kinda has a nice ring to it.

i did not even know you had a 2nd channel instant sub

I've bought several used pieces of equipment in my life, and every time I do exactly the same thing, replace all the fluids, filters, belts and hoses. Doesn't matter if they claim GrandaMa drove it to church or not. Good luck with it, I'm sure you already have several new tasks on your honey do list. 🤣
