Group,

I am in search of the top and bottom radiator hoses for my Kobelco K903B excavator. Part #'s 2444T2033 for the top and 2444T2034 for the bottom. Talked to the dealer and they said that there is 1 in Texas for the top but nothing in the US for the bottom. I really need the bottom hose more than the top. Any ideas where I can get one? I have done a ton of work to this machine and now I am stuck because of a hose.Kobelco 1.jpegKobelco 2.jpeg

I couldn't find your part number in the Kobelco Radiator software spare parts documentation. You could try measuring the inner diameter of both ends of the hose and sending me a picture of its shape. Alternatively, I could find a similar hose for a54081a02-b165-4041-bc1b-19711cee0feb.pngnother model and use it with clamps.

It will be a couple of days before I can get to getting the hose off but I will. Thanks for the response.

Looks like a nice restoration. I usually end up taking off the hose and going to a Napa and don’t tell them what it came off of and ask if I can go in the back to compare. I have usually found something very close and may have to shorten it.
