Part fell off, where does it go?

dablack · May 15, 2015

OK guys. I've got a B2620. I found this hose sitting right under my tractor. I don't know when it fell off. I always park my tractor here. I'm assuming it is a vent of some kind.

Any ideas?

Looks like it could be an overflow hose from the coolant reservoir.

That would be my first guess. If you don't have it figured out by then, I will take a look at mine when I get home in a few hours.

If not coolant, could be the diesel overflow coming off the fill cap area.

That's my guess!!!

Crank case ventilation?

dablack · May 15, 2015

Thanks guys. I won't be home until tonight. If it isn't pouring, then I will check the guesses and see what it is. I was on my way inside when I found it so I didn't have time to even look under the hood.

Looks just like my crank vent hose. My coolant hose is clear.

One other idea, some tractors have a front axle vent tube that will come from near the center of the axle and go up horizontal to the engine area. The idea is to vent the axle but be high enough that water wont get in if you submerge the axle in a lower water crossing or something.

Do you have a dog? Maybe he drug it over from the neighbor's house and is playing a dirty trick on you.

Is there any diesel left in your tank? :laughing:

Sorry, I couldn't resist.

I guess it could be the return fuel line... but should still be a heck of a mess!

Mine is old ,but it looks like the tube off the radiator neck

That is what it looks like to me also.
It should be connected to the valve cover.

Spare parts bin.

I used to have a 2620 and can't recall ever seeing anything like that. I think it might be the fuel overflow hose to direct overflow from the top of the tank area to the ground. Good luck!

OK guys. Between storms, I only had time to run out and pop the hood real quick. It is not the coolant overflow or the crankcase vent.

I'm going to check the diesel overflow line next chance I get......if it ever stops raining.

Billrog · May 18, 2015

OK check the front dif. vent there's a tube just like that on mine and it's the same dif. as Kubota has.

My bet is diesel overflow. Looks just like the one off my b7500

GPintheMitten · May 18, 2015

Shoot, my B2620 drops parts all the time. I just toss em in a pile until it shuts down.

If it is the diesel overflow line, I'm not sure how I would know. I popped the cap on the fuel tank and can't see anything there. How do you even get to that line to see if it is there or not?
