Oil Cooler Mount bushing

[RB]

My bushing (rubber mount), just broke yesterday. I can pick-up a new one from my local dealer, but this doesn't seem like a very good design, and i would rather improve the existing design.

I thought about a longer bolt that would sandwich a  hollow bushing between the cooler and the valve cover mount, eliminating the stock rubber piece.

any suggestions?

thanks,

Probly the rubber insulates the cooler from the hot cylinder head.

Some epoxy glue can stick the rubber back to the metal bit if that's what's broke

I don't think the rubber acts as an insulator of heat transfer,but rather a vibration dampener. This brings up the question with this poor design, is the rubber isolation grommets to protect the delicate aluminum radiator from cracking due to the twins vibration?


thanks for the epoxy tip, didn't even cross my mind to re-glue it. Perhaps a temporary fix, but i really would rather figure out a more durable way to solve this issue.

Howie,
Your mounts sem to be older by a few generaions. I am going to go talk to my younger, spoiled bushings and use your harder working older ones as examples. Mine are 2006 and obviously think they don't have to work......rediculous.
Maybe I can source some 2001s to replace mines that beleive they should get a day off

Got a pic of the broken one, just trying visualize an improvement,

just the diagram above right now

Is the metal part just glued to the flat surface of the rubber, or is it glued inside a cavity of the rubber piece?

More than likely the failure was caused by twisting the bushing close to it's elastic limits, either during assembly or during a repair.  Your part also could have had a manufacturing defect.

i will admit that i have had the cooler off the bike on several occasions, and it is possible that i tweaked it a bit too much. If i had to guess i would say the most damage was done when i broke the cooler loose for the first time, suckers were tight, and not realizing how they were constructed, i may have done some damage.

Either way, i am looking to change the original damper.n Not to mention it will be a few weeks before i can get one.

McMaster-Carr has a pretty good selection, check the sizes against what you've got:

I've seen a few that failed, so it's not unheard-of.

hey thanks, i am going to find something on there to try.
In the meatime i actually found a local dealer that has them in stock....a total fluke
