Technical Creating simple isolation mounts with Sugru

Creating simple isolation mounts with Sugru

As part of my lengthy engine cleanup project here, I had some mounts that needed to be redone. I had been using small amounts of Sugru coupled with silicone tubing in the past, however I wanted to make an entire rubber bushing out of Sugru to simplify the design.

For those who don't know about Sugru, a quick search will turn up TONS of uses but not many in the automotive world. Sugru is an air curing silicone rubber that starts out as a moldable glue. I am a new user to the product so take my instructional with a grain of salt and do your own research if need be.

Below is the clamp, some tubing that matches the sizes I need for the holes, and a packet of Sugru. I used 2 packets for this mount.



The Sugru opened up and ready for use. Nothing to add or mix.



Sugru was wrapped around the tubing, then pushed into the mount. Remaining Sugru pushed in to complete. Now we wait at least 24 hours - this can extend based on how thick the moldable piece. You can remove the tubing and do some t******* after a few hours though.



How it looks after curing, tubing removed, before cleanup. I used a razor blade to cleanup the outsides after this pic was taken.



The mount removed. Since Sugru is a 'glue' it holds firm in the mount but it needs to be removed. I used dental floss to cut/carve the silicone away from the aluminum. I also made some slits along the holes so that it can be fed around the tube for installation.



The bushing in place, trimmed up and ready to go.



And now with the aluminum bracket



All finished, should work well for a long time to come.



Here is what my PCV line looks like with Sugru mounts

 

Sugru.......who knew?

 

That's new to me, but I like it. Well done.

 

Been wondering how long it would be before someone started experimenting with this stuff. Looks like I have my answer. Well played, sir.

 

I've been playing with it about a month now, but this is the first useful thing I've done. The rest of the time has been just playing with it to know how it works, cures, etc.

It is very soft, like you would expect with silicone rubber and bends back on itself without breaking yet it molds like clay.
