Silencer bolts stuck?

[Bodge]

Im trying to repack the silencer on my 97 yz125 but the bolts(allen key) are stuck. I assume they used some type of loctite to keep them in. Has anyone here ever used heat to remove these? I know its dangerous bec there is probly gas in the silencer but it wont be on there too long. Ive also tried to grip them w/ visegrips but that hasnt worked.

I don't think that heating the silencer would be a problem. Just be careful, The oil on the packing will probable smoke alot but it should catch on fire. This is just my opinion and I dont' know for sure. Good Luck!

use(ing) heat to remove these? ..... gas in the silencer but it wont be on there too long.

:laugh: :laugh:

but it should (not) catch on fire

I'm with cr250 on this one.... assuming he meant what I edited.... take it off the bike first! (for lots of good reasons)

The silencer is off the bike, im not that stupid lol.

the carbon most likely WILL catch fire, and it will smell to high heaven..but if you do it outside and are careful it should be ok.

Use a very small tip and a neutral flame and heat just the bolt heads. Use a spray bottle with water or a throttled down hose to cool the bolts after they are nice and hot.

They will turn right out after this.

I don't think you will need to get it that hot... if you do it right... in any case, being prepared for the worst is better than not being prepared..

Just heat the bolt till its hot then just cool it off w/ water? Will this heating/cooling break it free?

Heres a neat little trick i learned from one of the great guys at dirtbike com........Clamp your silencer down to a work bench and put a breaker bar (a peice of copper pipe) onto the allan wrench and it should break loose nicely

Yep.


It's rusty up here. All the car mechanics I know use this trick to free up bleeder bolts on calipers/wheel cylinders. I use it for any various job. Just yesterday I used it to get a bearing race off an axle pinion.
