B2650 1st oil change

[Chad D.]

Ok. I feel a little silly asking, as I’ve changed oil on everything I’ve owned for the last 30 years... Never on a tractor, so I’ve got a question or two.

I picked up an engine oil filter, an HST filter, hydraulic filter, 5 quarts of engine oil, and a gallon of UDT2 to replenish whatever I lose during the hydraulic filters change.

Everything appears simple enough. Dump engine oil from both drain holes. Replace engine oil filter, replace plugs, fill with 4.2 quarts. Yup. Easy.

Question is regarding HST and hydraulic filter changes. I’m assuming that if I plug any vents prior to filter removal, I may slow down the outflow of oil that doesn’t need to be replaced. Am I correct in assuming that the only vent is the little rubber elbow on the 3-pt hitch? I plan to cram a golf tee in that to plug it while I change filters.

Any other drain I can cork off to slow the flow? I know it’s not going to be a catastrophic amount, but if I can keep it to a minimum...

Thoughts?

Thank you for any positive input!

I have done mine many times. You are correct with what you posted. That is the only vent for the hydraulic system. I just plug that vent off also. Have the 2 new filters ready to spin on when you pull the old ones off. The hydraulic filter is the one that will really run. Not that bad to do.

You can also do the vacuum trick. Shop vac attached to the hydro fill plug and you won't loose a drop of hydro oil.

When mine gets filters it gets new oil so it's not a issue for me. The first (50 hr) is the most important one anyway because that's when you'll get all the metal filings out so it was a no brainer.

If you do just change filters park it on a slope with filters on the uphill side and you won't hardly loose any fluid. If you don't have a bank to park on pull the rear tire up on a block.

I did the 50-hour service last fall on my B2650. I wish I'd have just changed the hydraulic oil. I lost so much of it when I changed the filters it was practically an oil change anyway, except I wouldn't have flushed anything from the bottom.

That is what I did, too. All the fluid, including the front diff/wheels.

It made a difference in the HST whine, quieter now.

Well, that was about the easiest 20 minutes I’ve ever spent.

Park tractor on flat ground.
Gather all filters, fluids, and tools. My tools included a band type filter wrench, a ratchet with extension and correct socket for drain plugs (I think it was 3/4”, but didn’t pay much attention), and a golf tee.
Drain engine oil in pan. Both plugs.
Swap out engine oil filter while the pan drains. I always label new with date and hours on my boat motors, so did the same here.
Add 4.2 quarts of 15-40. (Doesn’t get stupid cold here in western Oregon).
Cram golf tee in hydro oil vent tube.
Swap out the two hydro oil filters. Yeah, I lost (maybe) a quart while replacing these. It was much less scary than some make it sound...

Top off hydro oil with about a quart. Done.

Check fluids and let ‘er buck!

I have to laugh every time I see these threads about how to buy a twenty or thirty thousand dollar tractor and then how to avoid losing any oil during a service to save a hundred bucks. LOL

I don't understand it either. In the early 2000's a full service on hyd and front axle was part of the 50 hr schedule. I don't see why it was changed because the metal filings are still in the cases. Maybe a parts guy came up with that so he could sell more.

I sure don't see it on the tractors that only hold a few gallons. Those guys would fall over on a big M series. Mine takes 22 gallons of hyd fluid.

Baffles me as well. Mine was the same deal at 50 hours, change every lubricant, fwa included. Make mine 22 plus 22....lol

I know when I pull the plug, you'd think there was an oil well in there....:Could be Kubota now flushes the cases after final assembly, but I doubt it...lol

If they do, they did a poor job on mine!!

And that oil was dark and stinky for only 50+/- hours.

Weird. My hydraulic oil is crystal clear at 52 hours. A bit grey when poured out of the filter, but that just meant that the filter is doing its job...

I’d have zero issue with changing the oil throughout at 50 hours if it were recommended, or even suggested if the oil is “dirty”. Since mine still looked fantastic, I’ll go with the recommendation of the manufacture...

If I remember correctly, my next engine oil change is due at 200 hours, with hydraulic oil at 400? I don’t know that I can push it that long and feel comfortable. I believe that I’ll replace all filters and oils on an annual basis. Condensation is not a friend of a lubrication system, and I’ll be lucky to see 100 hours per year...

This thread was not intended to turn into a debate on what folks feel that appropriate oil change intervals should be. It was started, by me, only to ask a couple of basic questions that a “first timer” to these machines may have regarding a basic maintenance operation. Thank you all for your opinions, but...

Chad -

I'd have been surprised if your thread didn't turn toward the change/don't change fluid discussion.

Seen that same discussion 100's of times in my 7 years here.

Not knocking any of the guys or your original question. Glad your service went well! I enjoy doing most service work on my BX.

As a group, we're all pretty dedicated to our tractors. We are also quite opinionated.

It's just what we do....

I did change mine at 50 hours....

So what you meant to say is I will sometimes go with the recommendations of the manufacturer? Odd reading those two things back to back - lol.

This is not a good place to hang out if you don't want to hear any opinions - lol.

That’s fair enough! Good point. I could have clarified more on that one. If I was a full time user, I’d go by hours. Since I’m an occasional use type of fella, I’ll go a bit more on the side of caution, but only based on the chronological time.

I apologize if I came across cranky in my last post. Wasn’t my intent! I do appreciate opinions and am quite familiar with the nature of forums like this. It was just a poor attempt on my part to steer the conversation back on track.

Oil at the filter will be clean. The lower drain plugs is where the real trash settles to and the poor front axle isn't even filtered.

The good thing about being a tractor owner is we get to make our own choices right or wrong.

I simply provided a reason to change the oil BEFORE the first recommended interval.

As this thread may be found by a future "first timer" that wants to understand the reasoning, it's there to be seen.

A simple yes or no answer usually creates more questions.

It is about education and experience.
