Model T Ford Forum: Forum 2012: Iron End Mufflers fit to pipe

Just assembling my cast iron end muffler to the exhaust pipe and notice that a "U Bolt" would serve no purpose as it can't squeeze up the muffler onto the pipe. I assume that it was just left as a push on fit and relied on being sandwiched between the fixed muffler and engine pipe? In my later 1926 i have slotted the muffler tube and added a clamp

Thanks Alan in WEstern Australia

It just pushes in. I use silicon on assembly and by the time it has burned away it should of made a carbon seal.

Muffler paste/cement also works.

Clamps were never used on any T mufflers. The later all-steel mufflers had a short carriage bolt and a heavy flat steel piece that kept the muffler compressed together against a rolled bead in the pipe.

That was originally intended as a "slip joint" to allow for temperature expansion of the exhaust system. The muffler was mounted (fixed, bolted) near the back of the frame. And with the engine pretty well set in place, the pipe would try to push things apart when it got hot. It would also tend to bend and warp the manifold if it was mounted without the glands (rings).
As time progressed, people did not like the rattle of the exhaust system. So auto manufacturers stated to make ridged systems with flexible mountings.
Later Ts had the steel stamped muffler end which gave more easily than the earlier cast ends and both bolted to the frame.

That "slip joint" also allows movement between the tail pipe and muffler when the frame twists, going through ditches and such. :-)

If too loose you can expand the tail pipe ,there is a tool but cant recall its name
but it installs inside the pipe and there is a nut to tighten and it expands inside the pipe
