My 2007 tb-135 specs out I.S.O. 46 a.w.

I've got takeuchis with nearly 10k hours, and all I've ever run in them is TO4 spec 10w. As a matter of fact, that's the only hydraulic oil for all of my machines.

Gotta be 15 years since I started using this brand.

Western to central Pennsylvania.0°F to 95°F.Only hydraulic oil related failures over 25 years here was the drive pumps and motors in my 1845C machines, and technically, it wasn't the oil grade. It was the 10hour shifts of high flow road saw cutting, with the alitec high flow kits that did NOT increase the cooling capacity. In other words, they cooked themselves. The failure manifested itself as loss of drive torque, exaggerated when the machine ran for more than 1/2 hour. That was over 20 years ago, and, ironically, they were running 10w30 with HTO additive.

Only place I dont use it is in loader axles with wet brakes. It makes them chatter. Deere HyGard in all wet brake axles.

I'm hoping I found a dealer that will sell me those 5 gal pails for $33.00 each. We shall see. Thx!

Call Takeuchi dealer and ask them.MPClick to expand...All my Takeuchis call for 10W30 motor oil for the hydraulics.I've been running TO4 spec 10W instead in all of the machines here for over 25 years.I've got an 11k TB180FR and a 10k hour TL150 all on original pumps and motors. Never an issue. I've also had a 23k hour Cat 322B, and I have several Deere 544G loader at over 20k hours, all on original pumps and motors.The rest of my Takeuchis haven't got as many hours, but, that's what is in them.Again, Takeuchi says 10W30.We only have 70 machines or so here, so, my experience says a TO4 10w will perform admirably.

Well those are some really high numbers, but I's assuming that your filters are changed properly as well.The TO4 spec 10W sounds good to me, with one MAJOR problem, I have yet to find it for sale anywhere at any normal outlets....Google doesn't seem to know either.Humm......That reminds me of this article I read on the BEST GREASE FOR HEAVY Equipment EVER! I was SOLD after reading that article! Then, I tried to find it and it was NOT to be had. So much for the BEST grease that you can't actually buy by any normal means or any normal outlets.???MP

Heavy Chevy said:I have a 2004 Takeuchi TB 135 excavator that I'm close to putting back into service and want to know what hydraulic oil should I use. One dealer that sells Kuboata's said use their oil at $82.79 per 5 gallons; I read that I could use AW46 hydraulic oil and then I called another dealer and they said I could use same oil that I use in the engine...as long as it is slick and wet.....which I use 15w-40 and I could mix it. I'm confused a bit now.....sure I could poor any of these into the reservoir but what is best suggested. Help please!!!Click to expand...Takeuchi spec VG 32 -4F to 86F , VG 46 15F to 104F, VG68 40F to 150F.I can email the chart in the operation manual .No where does it say any about 10w30 motor used.

Not 10W. I'm not going to argue that some guys get 10k hours on a machine, but those who do that are WAY MORE service type "nerds" than the average joe and actually DO the servicing like with filters n such at proper intervals which is going to make there machines last a a lot longer. My point it, the Manufactures make there recommendation from experience w THEIR machines. Something COULD be better, but in most cases they make a good choice.I know of 3 Type of machine "users".There are the BOB's: They use them and abuse them and unless some light comes on telling them something it wrong they just keep going.There are the CLIFF: They WANT to service there stuff as per the manual, but just dont find the time to do it. They do eventually get to it but it could be way after it was required.Then there are the CLARKS: I'll make this simple, you can eat off there garage floor...no need to say how well they care for their machines.Clarks machines can make it to 10k.....most Bob and Cliff machines don't ever seem to get there. I think it is wise to CONTACT the manufacturer then "just take some dealers word" on what to use, like ToolKing's point is made.

I am in Fl. and have been using AW46 for 7 years in my 2006 TB135

Finally reading the recommendations from Takeuchi again. I still stand by my TO4 10W. I've had zero internal pump or drive motor failures still.

Years ago I was talking to the Takeuchi USA service department. I asked him what to use for Hydraulic oil. He said to just use Diesel engine oil. I've been using Mobile Delvac 1300 15w-40 on my TB016, TL130, TB240, and TB153fr. Seems to work and it's easy to get.

There was a time when most OEM's specified 10W-30 motor oil to have a common oil for engine and hyd's. Running an AW32(10W) TO-4 oil will not hurt anything. It's likely a better oil for the system than 10W-30. Cat TO-4 is one of the highest spec. hyd. fluids on the market.

How about if you accidentally combine 2 different oils? Like when I bought my machine couple years ago hydro tank was low and I just added iso 46 without even asking previous owner what he had in it… guess that wasn’t too smart.

Engine oil has high levels of detergents in it, hydraulic oil does not. Also, multi-viscosity engine oil has lots of polymer additives (how viscosity ratings change with temperature). These additives are completely unnecessary for hydraulic systems. There are zero combustion byproducts needing to be scrubbed by your hydraulic oil. In a hydraulic system you want any containments to be carried by the oil to the filter, and not dissolved within the oil itself (the purpose of detergents).The vast majority of hydraulic systems run best on a single-viscosity "non-detergent" mineral oil, with high levels of anti-wear and anti-foaming additives (e.g. AW-32, AW-46, AW-68, etc).AW-46 is the standard warm-climate hydraulic oil (generally speaking).AW-32 is normally for cold weather, or machines purpose-built to run low-viscosity oil year-round.AW-68 is pretty viscous stuff. Usually see this specified for use within gearhead machinery (lathes).Caution - 10W oil falls in between AW-32 and AW-22 with regard to viscosity (see attached chart). If your machine calls for AW-46 and you're running 10W crankcase oil, your oil is probably too thin, and you'll accelerate wear on your pump (unless you're operating in sub-zero temperatures).https://oilviscositychart.com/assets/images/standard-conversion.pdfOverseas excavator manufacturers entered a phase of using engine oil in everything. The idea was that customers would be happier if they didn't have to stock various types of oils to maintain their machines - like Komatsu using engine-oil in lieu of gear-oil within their final drives. The problem happens when someone puts in traditional gear oil (because gear oil is traditionally used within highly-loaded planetary geartrains) and the seals begin to leak.

From everything I've seen, AW 32/10W is the most common hyd. oil. Gear pumps aren't too fuzzy about which oil they use. Just about all skid steers called for 10W-30 engine oil in everything the 80's and 90's and they used variable displacement pumps. It's only on some exotic hyd. systems that the fluid is very specific and using the wrong fluid can cause major damage. On an older mini-ex I highly doubt putting AW 46 in the reservoir caused any problems.
