Trick to repacking silencer?

(1/2) > >>

JAD777:
Hey everyone:

I have a 93 KX5 with what appears to be the stock (Powercore) silencer.  Based on a number of posts I had read about noise, weight, environment, etc. I had decided that I should repack it and based on the weight/sound, I suspect it is long over due.  The problem is that I can't get it apart.  There is probably so much gunk in there that it will not separate from the external housing.

Are there any tricks to this?  I have removed all of the screws, I tried tapping both ends with a rubber mallet, I've tried a little bit of heat and I've even clamped it in my vice and yanked on the pipe - Nothing.

Any thoughts or ideas would be helpful.

Rick:
I clamp the pipe in a vice (not too tight, as it will distort the pipe), and use a rubber mallet on the mounting tab to get the two to seperate.

Yep, I'm in the same predicament.

I've learned that you have to remove the threaded collars from the inside of the endcap, and FMF says you only remove the front endcap, not the rear.

I guess I'll go try beat on it some more.

SupermotoFan:
Sweet!

Remove bolts and inserts from inlet side, hold linlet in hand with silencer hanging down, smack mounting tab area with scrap 2x4 about a half dozen times, voila!

  :-D

mine caused the same - I clamped it like stated early and used a rubber mallet on the mounting bolts - it took a lot but it finally came off - I  dont think the other owner ever repacked it
