50 hour service better late than never

50 hour service, what oil in the front axle?

Finally getting on my 50 hour service a few hours late, I have the oil and tranny fluids figured out but what do you guys recommend for the front axle? The book says 90w gear oil or same as tranny oil, what do you guys recommend? I don't know what is in there now as I haven't drained it yet.

Re: 50 hour service, what oil in the front axle?

Dealer said 80-90 w just changed mine at 50 hr book and dealer said 1.9 gal 80-90 w after i had put in 5 qts i checked and it was over flowing am not sure if i did not get a good drain or what. I need to get some input that issue.

it seems that most guys put in the 80/90 but I went back in with the Mobilfluid 424 same as the hydraulic/transmission.. Be sure you are on level ground, and fill slowly and watch the sight glass little white ball in the bullseye.

Ya, I stuck with the Mobil 424 also, don't know if that is bad or not, I was on pretty darn level ground and it seemed mine didn't take as much as is listed in the book either.

I had a horrible time getting the right side to drain out of the front axle. I let it drain overnight and it was still just dripping. Am I wrong, but I think hydraulic/hydrostatic transmission oil and gear lube are 2 totally different animals? I am usually the one saying people are too worried about stuff, but even I worry about substituting hydraulic oil for gear lube. Do you guys know something that I don't?

I do know something you don't know, but not about what fluid to use, but about the slow drain on the right side,. It seem some of the units have a clip installed incorrectly, and it partially blocks the drain hole. Causing a slow drain out.. There are old threads about it on this forum. Some think that even though the hydraulic oil is in the axle at the factory, the consensuses that is because it is convenient to use it on the assembly line. But that gear oil is a better long term.. I dunno..

We are not substituting gear oil or Hydro fluid, we are discussing which should be used (matter of opinion), as both the oil and the fluid can be used according to the manual.

Blue beings you are in Wisconsin I would put the tractor trans fluid in it because of the temps you [and me] see in winter time. In the southern states I would go with gear lube. JMHO. CJ

Guys,

Should stick to the heavy gear oil (API GL-5) recommended - it has extra additives for heavily loaded gearbox not included in Mobilfluid 424 (I worked for Mobil as Industrial Lube Engineer). The front gearbox design is different than the rear which shares hydraulic/transmission fluid for lubrication.

Being in the northern latitudes, I recommend Mobil Synthetic 75W-90 GL-5 Gear Oil. Tractor drivetrain will not be nearly as stiff in the winter (presuming you use tractor in winter).

Good luck,

DeereMann

Hydro has to flow thru valves & cylinders at all temps. Gear oil has to spread & stick where it goes, and to provide EP lubrication. Does the manual really say to use either one, or is that kinda left out and up to owner interpretation? I'd use 'gear oil' in the front axle if not specified otherwise by Kioti since there isn't much high-flow or high-speed going on in a geared/driven axle at tractor speeds, even in winter's cold.

I wouldn't want just hydro in something with gears esp during warm weather & I'd bet few of us would want to drain/refill seasonally to get the best of both. Please educate me if I'm that far off base. :confused3:

Uh oh, simul-post, but I agree 100% with fellow Northerner DeereMann.
