New Buyer Iseki TL2300

[lens12]

I'm quoting from the operator's manual what Iseki recommends. I don't agree with it. I think 80/90 is too thick, especially in cold climates. There is some debate as to if the recommendation is correct. I have a G274 that we use universal hydraulic/transmission fluid in the transmission. I can't see why universal hydraulic/transmission fluid would cause any problem. No US manufacture has recommended 80/90 since the 50's. I called John Deere & asked about using JD303 in my JD70, but they still recommended gear oil. So it is up to the individual owner.

These are all from my manual. I have been using 80w 90 oil, but I bought a gallon of Coastal Multitrac Tractor fluid, and I was going to use that. It says it is a good replacement, but I am not sure. I may just stick with the 80w90. It has worked well so far. I cannot find straight 80 weight oil. The manual says not to mix 80 weight and 90 weight, but I think that 80w90 is different. I am not sure if I should stick with the 80w90, or try the multitrac hydraulic fluid? Also TSC carries straight 90w oil. The manual says this is ok in the front diff, or the steering box, but it says 80 weight in the back. I am confused too.

There is a chart in an older post of mine here: http://www.tractorbynet.com/forums/mitsubishi-satoh/230975-s-373d-fluid-capacities.html#post2662966


I'm not a tribologist, so am only going by what a couple years of chemistry in college and some research online has taught me. At 100 degrees C, 40 weight engine oil is about like most 90 weight gear oil at the same temperature. UTF is about like 20 weight motor oil, or 80W gear oil.

Put differently, once the fluid is warmed up, it all has about the same viscosity. At low temperatures there is much more difference. I think if the manual recommends one type, that may be best, but I doubt anything will be ruined by using similar products. I have read many people recommending ATF for tractors in some conditions, to improve function at cold temperatures.

I like gear oil in front axles because I'm more comfortable with the additive package for that application. And, at normal temperatures,the thicker fluid doesn't drip as much out of 35 year old seals.

I have had several motorcycles that recommend either gear oil or 10W-40 motor oil for gearbox lubrication, so it isn't only tractor manufacturers who advise this.

A lot of brands show both specs
this is for Textran TDH Premium

KEY PROPERTIES

SAE Grade J306 (Gear) 75W-80

SAE Grade J300 (Engine) 10W-30

I put John Deere HyGard in my Iseki and its a manual ..

Apples and oranges here and one cannot compare the two. I am referring to a TL2300 which is a totally different animal than NH Mitch has and others......Yes, I totally agree that using "GEAR" type oil......80/90/120/140 in a front end is what one would do. The question is, using this type in a system that the transmission AND the hydraulics, 3PH-FEL operate together would this be correct??????????

OR.......Is it pretty much the same thing and can be applied across the board no matter what the brand, type of engine/trans/hydro??????????

Again, comparing apples and oranges on this with operator manuals that are for one type of engine/transmission/hydraulic system against another type of system is not accurate and a disservice to the reader possibly...............

HMMMMMMM what to do for my TL2300 and in fact the whole TL series??????

God bless........Dennis

Maybe I know less than I thought. The picture from several years ago seems to show a standard gear shifter for a manual transmission. Is the TL2300 different than a regular geared transmission?

According to the manual, yes, gear oil is specified to be run in the transmission and hydraulics. I linked to the picture because once the fluids are hot, their viscosities are approximately the same. When cold, though, the gear oil is much thicker, so may be a little slower in being drawn through filters.

Is it pretty much the same thing and can be applied across the board no matter what the brand, type of engine/trans/hydro?

I don't think tractors of this vintage, from any manufacturer, much care what is used in them, but there are probably some caveats. An HST will be much more picky, and likely need a specific fluid, compared to a gear transmission. Engines should only use engine oil, not UTF or gear oil. UTF makes sense to me in transmissions which serve as hydraulic reservoirs, but gear oil will work. But I imagine that ATF, UTF, or gear oil would all serve fine in gear transmissions and hydraulic systems, with varying degrees of sluggishness in cold weather.

Hi Dennis, I have been looking for a manual for you online, I have not found one yet, but I may, I keep finding more and more. I'll see if I can get the requirements for your tractor. Sorry, I didn't mean to throw you off with the manual exerts that I posted, I was just confused about what I have been using myself. As soon as I find something additional, I let you know...You should post some photos of your new tractor for us, I would like to see it!

Mitch......THANKS for the thoughts Bud....Good luck on finding a manual for the TL series stuff.....lol...I got a Jap version of it and took it to school with me back when I was teaching......The Japanese language teacher would give the students extra credit for translating various pages. Real world extra credit and all that. For me though, I have had this ol workhorse going on 10 years now. Golly has it been almost 10 years that I have been looking in on this forum. Seems like last week........

Anyway, thanks for the thoughts guys and I guess the the Universal Tractor Hydro stuff I have been using for all these many hours and the seat time involved to get them have passed my muster and get the nod of the head from most of you........God bless.....Dennis

Thank you all for the input, we operate in warm weather will use 90 in the gear box and ATF for power steering
:thumbsup:

Thanks! After researching old threads, talking to you, and calling people, I think I've educated my ignorant self enough to replace all the filters and fluids and purchase the manuals. I'll let you know ihow it all works.

Once again, thanks for the help.

I recently purchased an ISEKI TL2300 and I am looking for guidance on how to change /clean all the filters associated with the hydraulic system. I understand that there is the spin off filter that is by the oil filter but is there a separate mesh screen somewhere else or a suction filter?
