OS .46 Muffler bolt
 

Anyone out there know where I can get the bolt and nut for an OS .46FX muffler?

Thanks in advance.

I assume your talking about the long bolt thats runs through the lengh of the muffler. I would go to the hardware store and get 2-56 threaded rod or even 4-40 threaded rod and get those nyl-lock type nuts and make your own. If you tighten them too much they will break when the muffler gets up to temp. I'll just tighten them enough so the muffler is tight and go a little more.

Here are a couple of answers. I assume you have lost or stripped the long bolt.

If you need a new muffler, the muffler for the Tower .46 ABC first right on. Some people claim it actually adds power to OS and Thunder Tiger engines. I have never checked it, but I have one on my TT .46. The good thing is the Tower .46 muffler is $12.99 post paid. Tower doesn't charge for shipping tower engine parts.

Next, to replace the long bolt, use a 4-40 or 6-32 threaded rod. You may have to drill the holes in the muffler out. Put a fiber insert nut on one end, reassemble the muffler using hi-temp silicone on the center joint, then add the nut on the rear end of the muffler. I also use Lock-Tite on the threads and then coat the end of the threaded rod and the nut with Zap-A-Dap-A-Goo. This sounds extrame, but I've never had one come off since I started doing this.

Zap-A-Dap-A-Goo also holds wheel collars on landing gear and nose gear struts where they come through the motor mount.
