FE07 Posted October 26, 2014 Share Posted October 26, 2014 Anyone have a source for the rubber bushing/isolator that mounts the rear of the muffler to the bracket in the back. Mine broke off. Looks like a good thing to keep around as a spare as well. Jim A. Link to comment Share on other sites More sharing options...

wemtd Posted October 26, 2014 Share Posted October 26, 2014 I had to replace mine with one from McMaster. http://www.mcmaster.com/#vibration-damping-sandwich-mounts/=ubpycy ended up being 8$ for two and shipping. Link to comment Share on other sites More sharing options...
Klasik-69 Posted October 27, 2014 Share Posted October 27, 2014 Also, you may want to look at a Graingers store if you have one near you. If I remember correctly, they are referred to as vibration isolators, 5/16" thread on both sides, 1" thick. Some of the larger Ace hardware stores also carry similar isolators.

FE07 Posted October 27, 2014 Author Share Posted October 27, 2014 Thanks for all the replies. Always forget about McMaster Carr. Not much they don't have for hardware. Found what looks like what I need at Grainger. I'll stop there tomorrow to take a look. Thanks again. Jim Link to comment Share on other sites More sharing options...
CASwede Posted October 27, 2014 Share Posted October 27, 2014 Has anyone else sandwiched a small shock bushing between the exhaust and body mount using a smooth shank bolt and washers? I picked up the idea off the old Blatchat after having gone through a couple Caterham bushings in a year. It feels to be working very well, and there is no chance the two sides will separate. Compression damping is preserved, though I've lost the expansion damping properties. I expect I'll know I made a mistake when my muffler joint disintegrates.

raceral Posted October 27, 2014 Share Posted October 27, 2014 I just used a rubber shock bushing, usually free at most any muffler shop. Al Link to comment Share on other sites More sharing options...
nick47 Posted October 28, 2014 Share Posted October 28, 2014 I just bought a couple of the McMaster-Carr isolators, the extreme temp version. They seem to last about 5000 miles. Link to comment Share on other sites More sharing options...
rx7locost Posted October 29, 2014 Share Posted October 29, 2014 The usual mounting using a bobbin isolator side-loaded always seemed just wrong to me. I mounted my muffler using a generic muffler hanger from Speedway, Summit, Jegs or ????. Gravity keeps it loaded vertical like it was intended to do. It will not tear itself apart like a bobbin isolator will as the engine torques. I could have made the chassis mount side a bit less conspicuous. I have 2 years on this design now and it is working great. Link to comment Share on other sites More sharing options...
