Kohler Muffler Modifications for Sovereign-Updated

Recommended Posts

Jan 27,2016 Update:I was just informed by a member that the heat shield on this muffler alternative will interfere with the lights in a 7117. No solution at this time. As many of you know, I bought a Kohler muffler (Kohler #2406811) that's about 1/2 the price of a Simplicity OEM muffler for my Command install in my 2nd 75th Anniversary Sovereign. I finally finished the muffler modifications with the help of my neighbor. This is a pic of the muffler mounted before modification:

First order of business was to cut the heat shield mounting brackets off the Triad muffler. Since the Kohler muffler is a little narrower, I decided to modify the brackets instead of drilling almost overlapping holes in the heat shield. After I modified them, I used a spacer bar (not shown) to set the distance apart while the brackets were welded to the muffler.

Next the muffler outlet was bent straight down:

I didn't have the muffler on the tractor for the modification; overshot the left/right bend a little. I could re-bend it but I think I'll leave well enough alone.Some pics of the finished install (except for the clamp):

The Command will bolt right in newer Sovereigns. You may have to drill some mounting holes in older ones. The Triad wiring harness can be used with some simple changes/addition.

For complete info, see the detailed post about the install:

PhanDad --

Did you fabricate or purchase the exhaust outlet? If you purchased it do you have the part number and the name of the company you purchased it from?

Thanks,

John,

I'm not sure I understand your question. The Sovereign Command exhaust pipe, like the Sunstar Command exhaust pipe is a single piece of exhaust tubing bent at one end and swaged at the other end to fit the Simplicity muffler outlet. I don't know at the moment whether the outlet on the muffler PhanDad used is the same diameter as the Simplicity spec Command muffler. Incidently, both the Sunstar and the Sovereign Commands use the same muffler but different exhaust pipes so PhanDad's solution could also be used on a Sunstar.

I've printed 2 copies of your detailed post triad to command for my shop and refer to it often https://simpletractors.com/forums/topic/51265-kohler-triad-replacement-command/

when working on my Sovereign that had been repowered but haphazardly wired. My mechanicing bucket list includes finding an eligible Sovereign roller and good used Command to complete my own repower.

The exhaust connection on the Kohler muffler pictured above is the same diameter as the OEM Simplicity muffler; the "stock" exhaust pipe mates to it without any modification. As to the exhaust pipe, the part number listed above by Carl is the correct one. Apparently Simplicity now makes them from a precious metal; current Jack's price is $100.00! When I bought the one pictured, in June 2010, it was $22.35 which I considered expensive at the time. I didn't use it then since the Simplicity Command replacement muffler kit I used came with an exhaust pipe that is shorter than the original. Here's a pic of the Simplicity replacement muffler for the Command (part #1686656):

You can see the outlet is several inches lower that the original or Kohler muffler pictured above.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
