Title: Muffler Clamp
Post by MnSpring on 09/27/15 at 10:49:46

Muffler Clamp.

Noticed the other day, it was loose.
It slowly got looser, (I guess), over 2000 miles.
Yesterday, I noticed, the ’sound’ was different.
This morning, everything, except, that clamp, was tight.
So I loosened the two rear muffler bolts, the front, Shield bolt,
Checked the header bolts, (Still tight).
Tightened up the Muffler clamp, then the Shield front clamp, then the two rear bolts.

But the Muffler, still is Not tight to the header, and it still moves a bit.
(Result a bit of exhaust leaking at the muffler/header junction)

(All Stock parts)

So, before I take it all apart, and McGiver something.
Is their a real easy fix, or a different clamp ?

Looked at (search) Muffler Clamp, and they all were,
Putting a different muffler on. But the Harley one, was most suggested.

No, muffler, ’Tape’, had a hole in the pipe of a Pinto once,
Gee I said: this ’Tape/Wrap’, looks Really Easy.
A month later, the pipe broke in two, as everything under the tape, totally rusted away.

T clamp

Look it up. They're for sale in the industrial supply part of town.
Savings are tremendous. Like the bearing problem I can solve for pennies under thirteen dollars for two bearings by going to the Bearing service and supply versus the Lawn and garden,lawnmower sales and service place, twenty bucks EACH, plus tax.
Or, for the absolute know nothing
Mr.Fix it, a hundred dollars for the spindle assembly.
Poor dummies spend two hundred dollars to do what I did for twenty six bucks,,
But, some of those dummies make six figures,, so, whozethedummynow?

The muffler heating and cooling (plus vibration) may be to blame for the clamp being loose.

I wrapped my header end with thin sheetmetal (the soup can fix didn't work). Prior to the sheetmetal wrap, I used high-temp silicone on the end of the header to "glue" the sheetmetal to it. A little high-temp silicone on top of the sheetmetal (between it and the muffler) will help seal the muffler for a leak-free fit.

I was desparate and couldn't source a T-clamp as fast as I needed it so I went to the hardware store and picked up one of those PVC connectors that are just rubber tubes with stainless clamps. The clamps are much wider than standard hose clamps. A few thousand miles later and all is good. The clamp has discolored a little from the heat but it holds tight under load. You may want to hide it with a heat shield over it.

You cannot beat the Harley Davidson muffler clamp and they are cheap.

The only problem with buying used Harley muffler clamps is that the nut on the clamp eventually fails from all of the heat that a Harley generates and then the clamp will not stay tight.

IIRC the part number for the clamps 65296-95A and they are about $6.00 each. Every Harley dealer has them in stock.

I'd do that and I am cheap.
