Kubota part question -- John?

[Sean]

Folks,

This 20+ year old coolant hose on my Kubota V1902-powered generator is leaking.  At least I hope it's just the hose.



Can anyone tell me if there is an off-the-shelf hose that might work?  Alternatively, if anyone knows the inside diameter of this hose, that would help.  I'd rather not take it off until I have the replacement in hand, since I know a bunch of coolant will have to come out.

Lastly if anyone (Big John the Kubota dealer?) happens to have the Kubota part number for it, that would help, too.  I'd rather not order it from Kubota, as they are very proud of their parts.  But if I do, knowing the part number will be a big help since I am likely to get it from a tractor dealer rather than an equipment dealer, and getting them to look parts up on these engines can be a challenge.

Looks to go from the thermostat housing to the water pump, so I am guessing it is the bypass hose.  It makes a pretty tight 90 so generic (unformed) hose will not work.

Thanks.

Hi Sean,

I work on a lot of weird projects, and when I need a offbeat molded hose, I go to the local Carquest and just browse their inventory.  Many times you can find a hose that  will work fine.  Might involve cutting the section you need from a longer hose.  When that fails, ask to look at the paper catalog.  In the rear sections there are pictures by part number.  Dimensions are usually included, so you can tell the inside diameter.  Again look for one with a  bend similar to what you need.  I often order a couple, and pick the best when they arrive, and cut out the section I need.

I know this involves removing the old hose before you have a replacement, but would be better on your schedule than a failure.

Hope that helps!

Hello Sean,    I keep a section of 5/8 and 3/4 automotive heater hose just for emergencies , you form the hose in a circle and it will fit in a very tight place. Make sure it is long enough not to crimp. It's got me home several times,   Glen

Hello
hear is a read neck idea

go get some 5/8 bendable copper and go to an electrical shop they will have a pipe bender bend to the c -shape you need ans flare the ends and then all you need is 2 peice of straight 5/8 rubber  hose ,sometimes a good plumber will have a bender and a flare tool

Thanks for the responses.

Turns out the Kubota part is not all that expensive, $5-$7.  The challenge now is to find someone along my route who has it in stock.

The logistics of taking it out, then driving around with it to find something that will work are just beyond our capabilities in anything but a true emergency.  Which is why I hoped someone here would at least know the I.D. -- I can probably match up the curve and length.

Several here have mentioned 5/8" -- are you sure that's what it is?

There is definitely not enough room for the copper bend with two straight hose sections trick -- the whole part is only 3" long.  Also, it is a complex bend, looking a lot like a jug handle.

Sean, the price is not that bad at Kubota last one I bought was under 10 bucks for the hose and the gasket don't break the bolts they are bear to drill out lol


good luck

Sean, I would need the engine model (It is right under the bleeder hand screw on a machined surface) to insure the right one. Any Kubota dealer can order it If you have the part number. Remember that Kubotas are built in Japan, so they have metric sizes.

sean, your research capacity seems usually very good, but i don't see where you got an answer to your part number question about your kubota v1902 engine hose?  before i start digging thru my stuff to see what engine i have and if my kubota has a similar hose, just wanted to see if you still needed help.

sounds like you verified it is inexpensive, but not necessarily available, and still not something i would want to dismantle, then find out it has to be ordered from somewhere.  re-attachment could (and would if i was doing it) cause the the leak to get worse.

on my 15kw onan it wasn't the hose but the fitting it went on had corroded thru. Didn't mean to throw A wet rag on subject but ck it out. I truly wish it isn't but ck it out . Gen set was a 25yr old unit.
