I just notices a small hole in the radiator neck of my JD 730. I was wondering if there ia simple way to plug it?
 
I saw in the parts book that you can buy a new neck, but I have no idea how you would go about replacing it.

It solders on.

If you have a degree of mechanical ability, and a little help from Youtube, it can be done.

Or take it to a radiator shop. Not many left, only heavy equipment shops, and they are pricey and generally not interested in the small stuff. It may take some begging to get them to repair it.

A welding shop could also do it.
 
The hole looks to big to solder . You need a piece of copper or solder a penny over it . Or drop a brass screw in the hole and solder.
 
Just solder it shut, a little bit of copper or brass sheet, both polished up with steel wool.
Acid core real lead solder.
Don't even have to drain out the water, just suck some out of neck.

Then relocate or bend, tie back, alter whatever rubbed that hole in it.
 
P.S.
JB weld might work.
But it might leak.
Then you have to grind or dremel the wad of JB out in order to try again.

If soldering leaks, it is much easier to do over than JB.
 
I have seen a lot of jb welded projects, good and bad ones, some of which I have done. if I had, had the tools or knowledge, or even the time, to fix the repair , I might not have used, the jb weld products way. if done right it can get you temporally out of a jam. most of the time , antifreeze causes the product not to hold, clean very good, solder or jb weld. I have to laugh when I see those flex commercials. mark55

IMHO, anyone involved in the ownership and maintenance of machinery, classic or newer, needs to have some basic soldering skills.

If you don't, there's all sorts of places on the net with basic soldering tutorials.

I'd polish up the area around the damage, lay a piece of flattened copper wire over the hole, flux it, and have it silver soldered in less time than it took you to put together your post and post it.

And it would be a permanent fix vs. "puckey".
