Front axle losing oil... B2410

tunin · Mar 11, 2019

Hi guys, I am losing oil in the front axle, not 100 %; where exactly but I think it is at the pivoting joint in the middle.

Does anyone what gaskets/seals I need, is there a kit to replace all of them?

Thank you.

Regards,

One thing to try is to drain all the oil and refill it with 80w gear oil. The seals will likely hold in the thicker oil

Thanks for the suggestion mate, I was thinking about that today but then I said, oil is oilm if there is a woren out seal it will seap out...
now that I have a confirmation that it might work, ai will deff try it tomorrow. Thank you.

Curious... What makes you think it is the pivot joint and not at the hubs?

Maybe the attachment will help

Hi, I lifted the Bota and cleaned everything as good as I could... used break cleaner to degrease... observed for a while and it is coming out from that area somewhere... My English is not good so I might have named it pivot point but fro the image you attached I am thinking it is item 120 and or 130.

I will take some photos tomorrow when I check again...

Most Kubota front end pivot points just have simple o rings and one seal on the pinion shaft.

Sounds like your process of cleaning with brake clean and looking for wet areas is a good one.

Good luck and report back what you find along with the solution.

Thanks mate, I actually emailed Messicks tractors, I’ve bought parts from them before, they would not ship to aeurope but I have friends visiting my country every now and then so I bug them to pack parts for me.

They sent a shematics to me but I can not figure out what exactly I need as the tech names of different parts is not something I can understand... ie. collar thrust, do I need that in addition to the O rings numbered 120 and 130?

Thanks a bunch guys.

That model had an option of BI speed Front axle, do you know if it has it or not?

tunin · Mar 12, 2019

Yes, mine has it. The handle is stuck but ihas the option. I bought this Bota last year with quite a few hrs. and the handle came stuck... but I like it quite a bit...

That changes things slightly as that has a gear case bolted to the back of the axle and you could have leaks in multiple locations.

Can you post pictures of where you think its leaking from?

Here's the parts diagram from Messick's for the Bi-Speed option in the event it helps the OP.

If there is a lot of axle housing play forward and backward with respect to tractor frame the thrust bearings (060 & 120) might need replaced.

If too much play otherwise the bearings (50 &110) might need replaced. Too much play with these might keep the o-ring from sealing.

Considering the prices don't seem too bad for these parts, I might just replace them regardless if the tractor has many hours. Of course this assumes the leak is from this area.

If the source of the leak is difficult to trace, I've tapped small pieces of paper towels or toilet paper in various places or dusted with talc powder (baby powder) before to verify the leak source. Of course dye made superficially for the lube and a good UV light is another option.

Good luck.

Uhhhh
What does this bi-speed dohickey do for the tractor?

Hi giys, thank you for you input, it is greatly appreciated. I do believe it is at the back side of the pivoting poing where the shaft goes through to the axle. Here are a few photos... I wiped it off then waited and waited, I might be out of oil...

tunin · Mar 14, 2019

The oil is dripping from within the red but I think it is coming iut of where the yellow is...

North Idaho Wolfman · Mar 14, 2019

There is just a simple O-ring seal in that location.

But since you are getting into it wouldn't you rather go through the whole bi-speed case and fix the non operational issue?

tunin · Mar 14, 2019

Thank you mate, You are right, I would try and fix fhe bispeed, is it only one braided wire link to the gear box of thebi-speed or is there more to it... i gotta try and figure out what it is...

What do you hpguys think, should I replace the bushings and fhe bearings as well when I replace that oring? I am sure it is quite a task to take everything off/out?

We do not have Kubota dealers in the country so I gotta figure out how to order and get these oarts...

Anyhow, thanks a bunch for you help.

Hi guys, just checking in to see if this is normal, I got a quote for a cable for the bi-turn for my b2410 and the price ws 142,-.

That sounds crazy steep, I don’t think a cable for a rolce royce is that steep?

North Idaho Wolfman · Mar 27, 2019

I posted this on your other post too,

Let us know if that's a better price?

I had the same issue on my B2400 and 1st I tried replacing the pivot ends front and rear (with new O-rings) lasted a few months before leaking again. If you have more than a small amount of wear on the bearing surfaces on the axle housing itself it will leak again. Fast forward to last fall: I ordered the complete front axle kit which includes the axle housing, front and rear pivot castings and seals etc. (mine had Bi-speed steering so a bit different and more work). The new axle and bearings are redesigned and completely different (better) from what you have now. This requires complete tear down of the axle and differential, I recommend having a shop manual for guidance.
