Loose radiator tube

Postby Jude » Tue Feb 21, 2017 7:05 pm

I have a loud rattle from up near the fan. I believe it is a loose radiator tube hitting the fan. What is the best way to fix this?
Thanks

A loose radiator tube would be spraying coolant all over, I suggest checking the over flow tube.
If you are not part of the solution,
you are part of the problem!!!

Sorry, wrong terminology. It is the overflow tube. How to I secure it?

It should be soldered to the neck, then about 3-4" down on the top of the radiator (you might spot a dab of solder there). The bottom of the tube goes through a strap that is under one of the radiator bolts.

Be careful soldering that. If you get the radiator too hot you may loosen some of the radiator cooling tubes.
It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something.

Hi,
You didn't say what year Cub you have, the newer Cubs in the 1970's had a different tube than the older Cubs had, I think.
Here is a listing at TM Tractor for the older style tube clip that holds the tube at the bottom, there is a pic of it at the bottom of the page, it is shown without the shroud. :)

Thanks,1949
Is there a way to temporarily secure it until I can pull the tank off?

Jude,
I too have a rattle that I suspect may be the same problem.

You don't have to remove the radiator to solder the top or to place the bottom clip.

Jude,

This is fixed now on mine. The bottom bracket can be turned in till the tube is against the bolster.

The top was against the radiator but was hitting the fan. I dropped the fan down a little and the problem has gone away.

Thanks, I'm just trying to avoid pulling the tank off. Is there a way around that?

Jude,
I think you can get at the lower bracket from the side, leaving the tank in place.

If you also have the problem of the belt stretched out too tight and have the fan hub a little high, well some folks can adjust that with the tank on, l guess it depends on the size of your hands.

I guess reading these posts again, I'm not sure how the tube is loose. Did it come out of the radiator neck?

John
