Just bought a used L245DT with a loader. I am attempting to change the engine oil and trans/hydraulic fluid. Completed the oil change, no problem. Now onto the trans/hydraulics.
It came without a manual, but I found one on the net. It recommends SAE 80 gear oil for the transmission. It doesn't talk about the hydraulic system, but from what I can gather it has a common resevoir for the two. I am no where near a Kubota dealer, but very close to a TSC (tractor supply company) store. The guy there recommended using Traveller® Premium Universal Tractor Trans/Hydraulic Fluid, but in looking at the weight specs it is a SAE 10W-20 oil.
I am guessing he is misinformed about the particulars of this unit. Can anyone recommend a proper non-Kubota made fluid to use in this particular machine. Something that can be purchased at TSC would be great, since its so convenient for me. You can see what they carry at http://www.tractorsupply.com.
Two other quick questions: 1) I located the area where the trans filter screen is located, but it is very difficult to see exactly where the drain plugs are in my black and white, photocopied manual. Can anyone tell me how many drain plugs there are and exactly where they are located? and 2) is the place where you add the trans/hydraulic fluid the plug right between your legs?
The loader I have appears to have a (separate) resevior located under the joystick for the loader. There is a big rectangular box underneath the joystick. Looks like there is a drain plug at the bottom of it. I guess I'll pull it and see what happens!
Thanks very for the advice. I still can't figure out why the owners manual states that the transmission requires, "Gear oil SAE 80." This is an owners manual I found online for a 1976 model L245. Mine was made in the 1980's, but I would think the manual shouldn't have changed??
I am just concerned about putting the wrong type of fluid in there and having it blow up on me!
Back when our tractors were new, Kubota didn't ship them from Japan with FEL's like they do today. The loaders were made for Kubota by Woods here in the states and installed by dealers or owners. My loader and backhoe are both Kubota brand but built by Woods. Check you loader and notice the SAE fasteners and fittings vs metric on the tractor.
I looked through my manuals and you are correct, only 80W is mentioned, but the manuals are for the tractor only, not a tractor with a loader. I have read many times here and on other sites that when a loader is plumbed into the tractor's hydraulics, 80W is a little thick, and a universal tractor fluid designed for transmissions, wet brakes, and hydraulics is a better choice. UDT or generic equivalent fits the bill. Just make sure the label mentions UDT and is not just hydraulic fluid.
