I am not sure what your talking about with that discription. But I am guessing your talking about a Canadian lever action rifle. I would not take a cenntenial apart it would hurt the value of gun. But if it has been fired I recommend taking it to a gunsmith that knows how to work on that model of gun.
Good evening, My name is ***** ***** I am happy to help you. The Canadian Centennial is actually a Winchester model 94. Here are some resources for disassembly.

I do not recommend you tube for any firearm info. Anyone can post info and lots of it is wrong.
The best way to learn how to disassemble and assemble your rifle is with the AGI armorers video. It gives detailed instructions along with showing you how everything works with cut-away guns.
