I'm wondering if the EPA or CARB has come up with a new scheme or scam to block removal, replacement or modification of a cat/non-cat muffler.
The non-cat muffler on my Husky 445 (purchased new Nov 2009) has 2 round metal rings pressed with an interference fit into the 2 deeply recessed holes on the front side of my muffler. The metal rings block access to the hex head muffler bolts located just behind the 2 force fitted rings. The rings look like thin flat washers with the center drilled out. The metal rings have writing on the front surface of them. The metal rings are missing from the IPB for the Husky 445. Will removal of these rings void the warranty?
My Stihl SH86 Blower/Vac (purchased May 2009) also has the same exact force fit rings pressed deep into the front holes of its cat muffler. However, on the Stihl, I can successfully insert a T27 bit into the Torx head muffler bolts thru the center of the ring.
I am trying to figure out how to remove the non-cat muffler on my Husky 445 to see what is lurking inside of it. How do you remove the 2 metal rings blocking removal of the hex head muffler screws with a socket wrench? Can these 2 rings be removed with a drill or a screw extractor? Can these 2 rings be reinstalled after they have been removed? Is there a simple way to remove a muffler without destroying the rings or the muffler?
I'm not interested in a radical racing saw. I just want a working saw that isn't turned into a gutless wonder by the Political Correctness of the EPA or CARB.
I'm confused about the purpose of these retainer rings. Are these pressed-in rings intended to prevent removal of the muffler bolts?; Or, are they just intended to prevent the loss of muffler bolts loosened by vibration?
