Broken bolt for radiator guard

Postby FlashBack » Wed Mar 11, 2015 12:30 pm



So I have a bit of a small issue. After performing an oil change on my GL1100, I was putting the nuts back on for the radiator grill and snapped the lower left bolt.
My question is:
A) Is this part of the radiator with the bolts welded to it or
B) a cover/ mounting bracket for the radiator that can be replaced.
The image below shows it as a radiator cover and appears removable without having to remove the radiator. Am I correct in this assumption?
Thank you

yes, that bracket is removable. the stock OEM part number of it is 85300-37-000 and the bolt size is 6mm x .25 you can either take it off the radiator and drill the broken bolt out and retap it for a new bolt, or, go onto eBay and type in to the searchbox......."83 GL1100 interstate lower radiator mounting bracket" and it will bring up a page with some radiator mounting brackets. you should be able to find one on there that's the right bracket for your radiator. hope ya find the one you need.

Thanks Stuart. I am going to phone my local motorcycle salvage yard, "CyclePsycho" in Eugene Oregon. I know they just got a nice 83 in so i am hoping i can get the part.
So does the radiator need to come out or is it something i can take off in place?

ok, from what my manuals show, there is a screen in front of the radiator which bolts to the radiator brackets which in turn bolts up to the radiator itself. I would think that you have to remove the screen first, then you can get to the radiator brackets. there's also a "how-to" article for removing the hoses from the GL1100's. if you scroll down the page, it will show where the brackets,( sides and bottom) bolt up to on the radiator. this is the only thing I can tell you about the brackets. I hope this helps ya.

is there any way you can remove the bracket and drill the broken bolt out?. if you can get it apart, you might, depending on how much thread is left on the back side of the bolt, take a pair of needle nose vise grips, grab a hold of it and turn it out. if ya need any help, im sure someone from here will be glad to help ya.

You don't need to take the whole radiator out. I have been doing a ton of work on my engine this winter and just put it back in. (I had removed the motor to do the work)
So, to your question-no. You can remove just the bracket (s). You will be removing the bolts that hold the radiator in but there is no need to go any further. In your case just remove the two bottom bolts and the bottom bracket will come right off.
As for the repair-I had to do this as well.
It was very easy and cheap:)
With the bracket off I just drilled out the broken bolt from the back and put a new on in it's place. I then fastened a nut to hold it ans using my grinding wheel I ground it down to match the other side-after which I realize I did not need to do all of that:)
I then used some JB Weld to hold it in.
The whole repair cost me less than a buck and about 20 minutes.
Let it dry and you are good to go.

hey robertdawber, I wasn't sure if the radiator had to come off or not, but from what my manual shows, it don't have to be removed, only the screen and the lower bracket. flashback, you should be able to fix it without any major problems.

As easy as removing two bolts. Replacement went right back on and I can now bolt my air dam on. Those bolts also secure the lower fairing bottom screw bracket. If done carefully, the lowers can remain on. Thank you for your discussion.
Where's my "Easy" Button? :D
