EXACTLY, and every OEM turbocharged, boosted car sold today has this insert installed for the top ring land. You'll notice 3 basic differences on Kubota NA vs. boosted pre tier 4 engines. 1) intake manifold, NA has a runner type or non plenum manifold, the boosted always have a "log" type...

You should perform a leakdown test on your machine at some point as the turbo install will erode the piston ring land on the top ring only and compression will suffer especially if you use much power over sustained time. These folks will help you also. https://www.countrysalesandservice.com/ I...

It's right behind the starter about 2 inches, red/white 12 gauge wire. You don't even have to open the hood. Mine melted at the heater connection itself on the intake, 6 mm stud, 10 mm wrench you can't miss it.

Follow the science, I say follow the money. Watch anything by Janet Ossebaard and do your own research, you will be pleasantly enlightened. Excellent clearing house of current conspiracy theories and some just could be true. SHHHHhhhh don't tell your family or friends you looked through any of...

Taking out the trash. I DO still hate my tractor!

I used an off the shelf connector crimped and soldered. Mine burned right at the connector there in the picture on the right.

Make sure the induction pre-heater is working (at the intake manifold entry). Makes a huge difference at cooler temps. Throw an amp clamp around the wire they draw 30 plus amps when they are working correctly. I disconnect mine in Summer by removing the fuse. You'll know it's right if the...

I'll tell you this for free. Go ahead, snowblow your yard with an open station machine when the wind is whopping whipping and the temps are around zero.....HAVE EFFING AT IT! I did last Winter when my cabbed machine blew up. My beer froze, my face froze, my nutZ froze and I hastily fixed my...

A quick fix or try would be to add a rubber jounce bumper from a car suspension. There are many varieties if you could get your hands on a few from an auto parts place or if you have a go to shop that does suspension work you could at least look around to find one to try. Cheap fix and easily...

More bolts never tightened. Block heater install is easy once you remove the exhaust pipe for excellent access. Used a 8 inch lone 3/4" threaded pipe to seat the block heater collar where the frost plug was. Installed the correct length bolts for the loader frame so they bottom on the frame...

Not mine, I agreed to do the first service on this L3560 with 135 hours. Obviously never touched, it doesn't look like the loader has even been greased. Loose bolts everywhere actually some falling out. Makes me angry to see poor dealer prep on a machine like this. Alternator belt loose...

Lord forgive me.....

Building an ejection seat for a quick getaway because I still do .........hate my tractor! Sending piston pix to the company so maybe I get my hard earner money back, let's see where this goes.

http://www.pentosin.net/specsheets/Pento_High_Performance_II_5W-40.pdf I buy this in 55 gal. drums for my business, it's great oil. Interesting you speak VW oil specs, 505.01 isn't allowed in their DPF equipped Diesels in lieu of 504/507 but if you notice this oil has the Mercedes Benz 229.51...

Bore is finished, I asked for an extra .0005", I got it and all 4 are perfect until I put the fuel back to her:pullinghair: Flywheel weighs 64 lbs. not that it matters.

Kubota Engine Dealer for New or Remanufactured Engines & Engine Parts I called one Kubota engine supplier in New Jersey they never returned my call. I've been Googling far too many hours trying to find info and these guys are on Ebay so I figured one call wouldn't hurt. Scott there knew exactly...

Kit came today, all pistons, Bearings, seals to rebuild this thing. Turbo pistons have a different top and the upper ring land is steel or hardened whatever. Looks like the turbo goes back on this lemon. I had no idea one can purchase the whole kit quite a stretch cheaper then buying just...

I just realized, this morning, why Kubota uses reusable zip ties. Heated all pistons to 350f, they all measure the same, nothing makes sense.

Looks like #4 piston expanded too much and seized in the bore. One of the others has started to stick the oil ring. These are aftermarket pistons from a reputable supplier, I spent much time measuring and comparing them to OEM and the cost was far far less but the price wasn't worth it. These...

Well she blew up again, not sure what happened but I'll find out tomorrow. I think it had like 4 hours on the new pistons. I really miss the turbocharger, it takes so long to get anything done without it, groundwork or blowing snow that is. I'll give you guys a little tip if you haven't...

Yesterday I sat in a Kioti RX7320 power shuttle cab. Lots of room and quite a bit higher than the L series Kubota, I guess comparable to the M series. Dealer is hunting in Ohio but I texted him and he thought around $44ish for that machine. If I can make it fit in the tractor shed I might bite...

The baby is dead. It runs just like it did new, all the services are up, all new fluids, filters, pistons, valve job, seals and gaskets. New alternator and A/C belt, A/C charged, timing checked on all cylinders, glow plugs checked and fine. For sale now or in the Spring, I need it to blow snow...

I don't think there's much for me to offer Richard. I think too much fuel killed the cat. It only boosted 6.5 pounds. If a guy ran the machine normal and not full tilt it would be ok. In my case pistons with steel ring lands would be the answer for longevity. I would imagine all of these new...

You are going to have a fun time with your project just like I did. Here's a pile of parts I just removed/replaced on my L3940. I installed a turbo and cranked the fuel, went from 39 to 60 hp. Engine went bad in 400 hours of hard working. Not saying yours will but most of my work is blowing...

Here.....wood, holding up the tractor, or what's left of it.

I'm starting to think my oil leak is the HST input shaft not the FWD shaft seal as the seal for the HST has no tension when you slide it over the input shaft. I was reading this thread and it makes sense and the part numbers listed in this invoice show the repair. My clutch is dry but the...

I read that pdf thank-you. Talked to a Diesel truck puller friend in Ohio today and described the damage, he thinks simply too much cylinder pressure and agrees the thing hasn't gotten too hot. Pistons came in and look nice, new shaft and seals should be here tomorrow for a weekend marathon...

Thank-you for the pdf. So my FWD shaft is bent and when I spin it the runout is about 1/16" which is quite a bit. I want to say maybe I bent it splitting the tractor but I have to say I was so careful it came straight apart very smoothly I just don't see how I could have bent the thing. Motor...

So I lied, I still own this turd of a machine. What a crapshow this repair is......

I wonder if the temp sensors are the same part number as I don't know but if 2 are the same try swapping them with each other. Also turbochargers don't have to have boost problems to fail, most oiling issues are because the centrifugal seal in the exhaust side gets plugged with crap then leak...

You'll need to design the tank with a low spot for the fuel pickup, all fuel injected gas tanks have an internal sump to "capture" the liquid in one area around the fuel pickup. If you catch even one slug of air the engine will stall immediately and you'll have to fool around restarting the...

There was a run of machines where Kubota installed the wrong glow plug and fuel solenoid relays. You have to pull the dash to check both. The terminals are supposed to be large but they installed smaller than specified relays with small terminals that won't make contact when cold. Good luck, Fred

Finally getting this old junker up and running. Still lots to do. Chevy LS1 power detuned to 2400 RPM with software

It's made by Taylor Pittsburgh and it is a rugged unit. The 2610 gear runs it very well. I turned my fuel up some for more power but even before that it worked well. Over the years of buying equipment I notice dealers try to sell smaller tillers, don't know why but this 72 inch unit is the cats...

Honda cars uses a nice oil filter made by Filtech. It's a direct cross to 1365. Very nicely made filter costs me about 6 bux. 15400-PLM-A01 or A02 fits almost every Honda and Acura out there. Honda motor company can't be wrong, made in Amurica too!

Once the lift pump or pre pump gets airbound forget it. Anywho at this point you must remove a hose from the lift pump which is located just below and left of the engine oil fill cap. Make sure you have fuel going in to the pre pump then crank the engine with the pressure side hose off and let...

He didn't even listen to one thing you said. R4s = buyer's remorse.

389 hours, turbo still doing it's job nicely. Popped a front knuckle seal. Everything is oringed these days so all you need are 2 seals and a cotter pin for the steering tie rod nut. Lots of metal in each lower front end final drive, there is only one way to get it out and that's to remove the...

Have here this new CK2610 gear tractor with turf tires. Took delivery late last week fresh off the truck from North Carolina. I promise not to bad mouth it or review it properly until I have 50 hours on the clock. Bought the machine to primarily mow my lawn with a rear mount Landpride 72 inch...

Been looking to replace an old Cub Cadet 7260 4WD 26hp gear tractor that I love dearly. Mostly mowing and rolling my driveway, 6 foot tiller, 6 foot rear mount mower and a 6 foot box blade, some wood chipping with a Woodmaxx 8 inch chipper. I like the light weight 2600 lbs. without FEL and I...

What snow? :-)

Humblebub is part of an elite motorcycle gang. Nobody's gonna screw with man on a British bike! I love it, Fred This camera works well also: The Tracker 2.0 with Infrared & Auto Tracking 30 times optical zoom. The road is 600 feet from the camera. The detail is incredible in the...

Follow along as I try to revamp this old 80s Reinco TM7-30X straw blower. She's been beat pretty badly over the years. She'll go or blow when we're done with her. Might take some time it took me a year to finish my stupid wood cart. Fred Dis-assembly reveals she's pretty far gone...

Or should I just scrap it? Got to drinking early yesterday so I figured I could rebuild this old jalopy that has served us well over the years. It's in tough shape, really tough after the grim reaper plasma hacker appeared. Might be quicker to start fresh. Fred This is the rig last Winter...

I thought they were all fixed by 2007 model year. Anyway GM warrantied plenty of those back in the day. They also make an adapter to fill the unit with grease also. Don't know the GM part number. Fred

So I have 50 hours blowing snow with it and now running an 8 inch Woodmax chipper. Before the turbo install the tractor engine would die out on anything over 5 inches of wood diameter. Now with the turbo you can't kill the engine, in fact Saturday I got a large piece of Maple stuck in the...

Thanks for looking all. I bought a new deckover tilt trailer to replace a 7 ton tilt I had. The old one, an Econoline 7 ton deckover tilt had a cushioning cylinder that would allow the deck to tilt when driving on. The new one, a Sure-Trac Sure Trac | deckover tilt has 2 powered cylinders. It's...

That 3400 starts great. I have been keeping my shop at 45 degrees to save oil and you must let the glow plugs run a full cycle to get it started. You should see the black smoke roll out of it when it finally does go. This Summer I will try to advance the timing a couple degrees and see what...

It's a 5 minute fix with just one wire and a new relay to replace the one you now have. You can buy a relay with 5 spades and utilize the blank slot in the socket already installed on your engine there. The only downfall to this is that the wire you install in the blank slot will only be powered...

I would assume the timer is built into the relay not the switch as with most Japanese designed automotive electrical systems from the 80s-90s. The relay part number is 3F740-75030. Chances are if you pull the roof off and trace the wiring from the defogger switch you will find the relay right...

To George the Beagle......If my owner ever ran me over and killed me because he bypassed the seat switch I would be a not very happy dead dog! Please fix the seat switch correctly so we don't have any accidents. Harry the Lab

I know it's me again with another question, I bought a new 5 ton dump wagon to pull with my L3940. The dump wagon has a hitch hole size of 1.2 inches and the pin needs to be about 6 inches long. My tractor drawbar hole size makes little sense to me as it is not a uniform size. It measures .987...

Let's talk cranking compression vs. leakdown test which I did both. Since the leakdown test showed almost no leakage from the cylinders through the valves/rings then cranking compression can only be low due to lower compression pistons or larger chambers in the cyl head. I am happy for this as...

Highly unlikely Aaron, remember I already tried a fueling increase of 1/2 turn. It smoked badly under load. It was 80 degrees that day and I had my 8 foot road grader on the hitch (IN THE AIR mind you) not engaged in the dirt. Medium range (not high for hill like early posted to p I s s those...

I'll admit I like everything I own to work perfectly and strive to make it like that. I should have tried before buying but didn't. I jumped on this because there were no more larger 40 series tractors around, they are gone. Took 2 hours this morning and set up a degree wheel to the front pulley...

Aaron my Volvo never ran right until I did a V8 conversion on it LOL. You guys gotta let up on me. You know you wanna see it happen. Fred

I used 3 remotes and the floater for my snowblower wheels. T-N--T kit comes off for Wintertime so the other 2 remotes for chute turn and deflection. Fred

8309 is just the valve section. He needs L8347 also which is the install kit with lever and teeny tiny cotter pins. Fred

I have been in the auto business over 40 years and don't mind tearing anything apart; it's putting it back together that complicates things :) This tractor is the right "size" for me. It fits perfectly in the shop, garage, tractor shed, on my lifts. It just needs a boost for certain things. I...

Tore things apart this morning at 5AM. Pulled the fuel tank and A/C bracket, valve cover. Glow plugs ohm fine (0.6 each) and I will do a baseline compression check and timing, valve adj. check before I put it back together. Gonna be a challenge to fit this all and make it look nice and still be...

http://www.tractorbynet.com/forums/kubota-owning-operating/286348-turbocharging-new-l3940-gutless-pig.html Had it 5 months now. Some good things to note: Cab heater and A/C works excellent. Bad things: Little to no power. If going up an incline and the Revs are at 2600 and I use ANY of the...

Although Mobil 1 is good oil I always use a European spec full synthetic oil such as any VW spec'd 502.00 505.00 505.01. Look for ACEA A3/B3/B4/C3 on the label. 5W40 meets your requirement for cold and warm weather. Your only issue would be using high sulfur Diesel fuel in which case you would...

I use a submarine bunk bed attached to a 3 point hitch. I know it sounds stupid but it is the only way I have found to smooth topsoil and 3/4" stone in the driveway. It is a tube frame 6 feet wide by 2 feet long. https://d18gmz9e98r8v5.cloudfront.net/ptr/20120719061523_685901241_1194_9.jpg...

Nice pix seeing as deere hunting is a few weeks away here. Fred

Mine is a Woodmax; I believe it is a similar unit as I downloaded the WC8 usermanual. It is 1 year old and works very well for how I use it, getting rid of brush while cutting firewood. I chip up to 6 inches. I had to cut and reweld the hydraulic pump for the feed as the belts were off by 1/2"...

Landing gear from a Cessna 150. Here's what I did, works well on the lawn and small stone yard. Pushes around the shop perfectly by hand. Need snow to try it out, and paint. This wasn't cheap and took many hours of fabrication, too much in fact. Rockshaft cylinder has 3 inch stroke from John...

A turbo? Pleeze? Pretty pleeze? Pretty pleeze with orange paint?

Instead of bashing my new powerless L3940 HST Cab tractor I would like to turbo the thing. I see the same engine is used in the Bobcat S-160 skid steer with a turbo. Rather than tell me why I don't want to do this can you throw me some ideas? Very serious here. Thanks, Fred

Hi folks, 1) Is there a way to get a price check for a Kubota 3rd rear remote kit L8348? 2) Would most dealers charge Kubota list price or higher for such kit? Thanks, Fred:confused2:

Hello and thanks for having me, Have some land and love to play outdoors. Every time I google a Kubota or Kioti, Deere question this forum comes up more than any others. That's why I joined! Fred
