New Kubota Corrosion

[oosik]

DEFINITELY!!! That is not normal. Something is going wrong there. I would ask Kubota to come have a look and ask for their appraisal of this condition.

My Kubota M6040 fittings and all piping looks the same as the day I bought it - brand new.

Personally, I would treat a single fitting, easy to get to/see with WD-40.
It seems that's what WD-40 was made for.

Wow, that is disappointing to say the least. I'm on my third Kubota (BX2660 2009 sold, B2620 2012 & B2650 2018) and have not seen such as in your pictures. Mine are parked under a tarp outdoors or in my ShelterLogic tent. I've never "wahed" them, but do wipe them down now and then with WD-40.

Maybe "salt" is the culprit?

I'd be interested to hear what Kubota says about this or....some other owners.

Cheers,
Mike

SALT SPRAY FROM JAPAN ON THE WAY OVER

Hello All, I have been reading a learning a ton on this site. Thank you to all who contribute.

I have a 1 year old Kubota 4760, 2022 model delivered in May of 2023. I am appauled by the corrosion on all the silver plated hardware. The tractor has 55 hours on it, and is kept either in my garage or under a 3-sided barn, it does not see the rain/snow. It stays on my property and gets washed a few times a year. I live in southern New Hampshire, not by the beach. It appears that just condensation has corroded every single plated fitting/hardware item. I have a BH92 on this as well, and all the silver connectors, even hose clamps, are corroded. Am I just expecting too much?

Some of the fittings say China right on them. I'm dissapointed and will now go and try to steelwool/oil all the parts, but what a waste of time. Here are pictures of the hydro connections for the FEL, under the cab and for 3rd funtion valve. I took these pictures a few weeks ago, on a warm morning. You can see some droplets from the humid air on the cold metal. Notice on the middle picture on the cab, some connections have zero corrosion, but most have the oxidation. I really expected more for the money spent on this. Any thoughts or insite? Thanks!

I run into that problem whenever I store stuff in my garage. Mine doesn't have much in the way of ventilation and the air is constantly damp. If your garage is like mine, things will las longer outside.

Really cheap metal and production on those parts, combined with something else. I took a ride years ago through a Cadillac dealership with my friend who owned a brake and alignment shop. All of the disc brakes on the brand new cars were orange with rust. His only comment was “cheap metal”.

Lol. “Tell me you don’t work on cars without telling me you don’t work on cars.”

Brake rotors just take humidity to rust. I think it has to do with them being cast. Every rotor I’ve ever met was rusty unless the pad had scrubbed it off recently.

It's sad to see the quality of the product has apparently been reduced over the years. I live in NH as well (between Keene and Concord) and neither of my Kubotas that live outside, have anything like that. The L3710 is a 1999 and the M6040 is a 2012. I've owned them both since new and have kept them out in the weather. Good luck!

THose parts come from many different sources and the probability the plating on all of them is defective is nil.

I suspect you have an environmental issue - either at your location or from exposure prior to you taking possession.

You could try Penetrol. It is like a thin varnish that will give some protection yet not interfere with threads or gum things up like paint. Home Depot has it. It is good for a lot of other things too.

Looks like salt corrosion

Looks like that to me, too.
