Farmall 140 Upper Radiator Hose Problems AGAIN

Well guys.......it looks as if I've ran into problems again with this upper radiator hose for the Farmall 140. I have restored a couple of 140 tractors that were 1968 models and the upper radiator hose (molded 90 degree hose) Outlet on the radiator had a different Outside Diameter than the replacement hose that is offered aftermarket. I've asked Ken Updike about this and noone seems to have an answer other than IH must have switched radiator suppliers and it changed, but then quickly switched back to the original supplier because I've restored other 140 tractors and didn't have this problem. I find it coincidental that I've had it happen on (2) 1968 models.

Now.......I've also posted about how not only have I seen where the connection on the radiator is different and the aftermarket hose doesn't fit, but I have ran into a completely different radiator (which supports the fact that they changed suppliers). That original "oddball" radiator was not repairable so I purchased (from Tim Talleur in NY) a used radiator from a 1971-1972 Farmall 140. I didn't have the original hose because it was damaged, and upon installing the "new" more common style radiator, I find that the aftermarket hose will not fit on the radiator side!! The hose Outside Diameter seems to be the same as the radiator outlet Outside Diameter. The hose might even be a 1/16 inch smaller.

WHAT IS GOING ON HERE?? I need to find a hose that will fit and figure out why the change. I'm sure I will run into this again. This is a specialty hose that I've found, and have no clue on finding an equivalent. In the past I was able to re-use the original hoses.
 
Take the hose to a NAPA store Ask to walk behind the desk to match hoses. Find a hose from 2000 of them with the right connections. You will need to look for a hose that has the diameters and bend, but may be a part of a totally longer, or different hose that can be cut off to match the needed section. I do it all the time just be picky and if needed, cut off more new hose than you save, to match. Prices will vary. Don't skimp. Jim
 
Jim, it has 2 different diameters on each end so that method won't work. Not that I've tried at least.
 
50 percent of the hoses at NAPA have different sizes on the ends. You walk in, hold the old hose up to the new one that has a bell mouth that is approximately right, then fit the new bigger end over a baby food jar, or such, that is the size of the rad inlet. it is perseverance that makes it work.

I would trying Jim but I don't have the original hose since this radiator was bought used from someone in NY. Last time I had to get a hose like this, I did take to Napa and they said they didn't have a hose that would work....even if I cut one up. I ended up using my original hose that time. This time, I don't have that option.

There are hundreds of hoses that have the right, differing, end sizes, I would not lead you astray on
this, The hose with the wrong size on the radiator end is the model. The baby food jar (or what ever
cylinder is the size of that radiator fitting) is the fit of the expanded end, Another solution is to
find a bent hose that fits the rad inlet, and is uniform in Inside diameter, then cut off 2 inches of the
original and glue it in the new hose with tire patch glue, after roughing them up with sand paper on
their mating surfaces. Jim
 
Take a piece of coat hanger wire and bend it as follows: Start by bending it 1/2 way around the engine
hose spigot. Make that curve fit the outside size of the spigot. Bend the wire end to fit the curve/s
needed to meet the rad spigot, and go on far enough to be clamped if it was a hose. This is the inside
radius of the bend. (shortest curve) Next bend the wire around the rad spigot all the way. Remove it
and adjust the curve of that bend until it is equal to the Outside size of that spigot. This wire model
will allow you to choose the correct hose part from the rack. There is no more clear way for me to
explain this. Measure the spigots diameter and measure when you look. There is no actual part to do
this. It innovation! Jim
 
Now that is an idea Jim. I believe you, it is just that I've had problems finding something and I really want to know when and why IH changed the size so I can be prepared for the next time I run into it. It is funny to me that before I restored these (2) 1968 model tractors (one of them now has a 1971-1972 radiator), the aftermarket radiator hose worked just fine. Also wondering if anyone else out there has ran into this and how they remedied it. Thank you again and I will continue to research.
 
How long is the hose? Is there room to make a reducer out of exhaust pipe material? Find 2 hoses to fit the radiator and engine & use the reducer in between.
 
I ran into this with my 154. Noone had one in stock that would even work, or was even close. I got one of those flexible hoses that was made right, just wasnt the exact hose for the tractor. It was a tad long, like maybe an inch longer, but it works just fine. I did have to twist it somewhat once i got it in place so it would rub on the hood, but it works.
 
Another option is to swap the radiator outlet size. There is a radiator shop in the town I live close to and he is so cheap on doing that kind of thing that I have never messed with it myself, but it wouldn't be hard to swap with the outlet from the old radiator or even just another similiar radiator.

When I swapped the D358 into my 560 I was going to have to use a pipe to route the coolant from one side of the radiator to the other for the water pump connection. Instead of that I took it to him and he cleaned , cut off the old connection, moved it to where I specified, and pressure tested the radiator for less than $50. I think he even repair a small leak or two in the process.

I've thought about this but thought there would be an easier fix

Right, they SAID, as in, they did not want to expedn the effort of trying to find a hose that would work.

The key to Jim's advice is to find a place that will let YOU, yourself, physically go behind the counter and paw through their radiator hoses to find one that will work.

One day I had to do this just to get a straight piece of hose. I needed one for a Shop Mule (same as a Farmall A). Went to the closest Auto Zone only to find that they didn't even have straight hoses for cut-to-length. They let me look over their rack of curved hoses to see if I could find one with a long enough straight section. Turned out I found one that was long enough to make two, which made the unit price pretty reasonable. I still have a spare.
