L2501 HST. I know the manual doesn't call for it at 50hrs but I've seen some people suggest doing it at 50. I cant decide if I should or not. I dont mind spending the money if it's for good purpose but I'd hate to waste it if its not necessary. Also what about the front axle? 50 or 400?
L2501HST 50Hr Hydraulic Fluid Change?
- Thread starter Eesquibel
- Start date
I did the all the fluids at 50 hours on my B2650. I am glad I did. The HST and axle had metal fines in them. Not that they couldn't stay there until 400 hrs. There is no filtering system in the front axle AFAIK.
As you are changing the hydraulic and HST filters you will catch some of the hydraulic fluid, this will allow you to inspect the Super UDT2 fluid and then you can make an informed decision. If you don't mind the cost I would replace the fluid after the initial 50 hours, you need approximately 6.2 gallons ($125 - $130). From this point you can follow the general fluid change recommendations.
I often change my fluid earlier than the recommended hours due to the low hours I put on the tractor each year. Typically I will change it at 200 hours as it may be 5 years since the prior change.
As commented above the front axle has no filter, my personal opinion is to change the front axle fluid no matter what as it only takes just over a gallon.

I bought a large oil change bucket at walmart and drained the hydraulic fluid into it.
Then just reused the hydraulic fluid aftet changing both filters.
I changed it on my L2501 HST at the 50 hour service (49.6 actually). A good side effect, it dampened the engine whine like some others on this forum have said it would. It used to be loud in High (M and L, too) running between fields but now it is only noticeable when you first start rolling at low rpm.
I checked the front axle level and it was good but I intend to change it to 80W-90 gear oil at 100 hours.
I also added the smaller, internal air filter as my land can get pretty dusty in the hot Texas summers.

I think you will find folks split 50/50 on this topic. On my previous L3410 I changed the fluid at 50h, and on my current L4060 I did it at 400h.
That’s exactly what I’m seeing. Did you notice any difference in anything at changing at 50 vs 400? If you had to give me a recommendation would you say do it at 50? Or don’t waste your money and do it at 400as Kubota recommends?
Not that you asked me...
If you really want to protect the tractor and not waste resources, change the oil (& filters) at 200 instead of 50. At 50, just do the filters.
I didn't want the metal fines I found floating around in there another 350 hours. The first change done is the most important as it is getting all the metal fines (from manufacturing) as well as break in.
Metals fines are why you use filters... they get captured within the filter. The oil (once filtered) is perfectly fine....
I did not notice any difference in the 50h vs 400h change, either in operation or fluid appearance. Fluid appearance is a poor indicator of condition anyway.
"If I HAD to" I would say that since you are putting the thought into this and you state that money is not a driving factor, then change it out at 50h for your peace of mind. There is no penalty other than money and time.
I have a 5gal pail full of UDT2 from my 50hr that looks like it has swirls of metallic in it. All the filters were on my tractor prior just filtering away.
I am a cheap Yankee. Believe me I would have left it if it was clean. It was exactly what I expected for a new unit assembly after break-in.
After changing it I can say it is nice and clean looking still (just did the 200hr service).

One thing you can do is drain a bit of fluid from the lowest drain holes to get any metal out from the bottom, then replace with new oil, or filter the old..
