DK45SE HST FRONT AXLE OIL

[grm61]

So I'm going over my tractor, I have twelve hours on it..Curious I pull the fill plug on the front axle, and dip a zip tie down the hole to see what kind of oil is in it, and it appears to be a hydraulic or tractor fluid in the front axle..

I half panic, expecting a 80/90 gear oil up front, so I get the book, but I really can't understand it, it says BP tractran uth and then under that it says oil, 1.9 gal SAE 90 or better or same as T/M oil...I'm guessing T/M means transmission?

So I'm really not clear on what is supposed to be in it.....

You can use either one.
I believe they come with hydraulic/transmission oil in them.
I run 80/90 gear oil in my front axle

100% correct. i also asked my dealer about this. either is approved. I chose 80/90 also after 50 hour

Heres the service manuals specs::

Yeah,I noticed the same thing on my DK40,I emailed Kioti and the said what the others are saying.I went with tractor fluid because that is what the factory puts in and also because I hate the smell of gear oil....YUK!!

The reason they are filled with UTF is for convenience on assembly line. Running 75W90 full syn in ours.

I wonder... if that seal ever goes bad at the front axle, if you could wind up with 80/90 in the hydrostat through that torque tube or whatever it is. I don't have a parts or service manual yet so I don't know whats in there.

Thankyou for those files, yep it says right there to make it easy on the *** line, I've got some Schaefers 80-90 that I'll use at 50 hr service.

I'm assuming your talking about the front drive shaft.
The answer is no. Gear oil will not get in the transmission oil.

IMHO if you are ok with UTF in the rear transaxle (where all the heavy lifting is going on)why is it such an upgrade to put gear oil in the intermittent use front diff.? seems to be a "feel good" thing...Mike.

Maybe being a heavier grade? Got me thinking now!!
