You need to be more specific and identify a manufacturer and model, i.e. Winchester Model 94, Marlin Model 39, etc. For the most part, you don't want to dissassemble beyond what the owner's manual recommends for cleaning.
Go to the Gun Digest bookstore at http://www.krausebooks.com/category/firearms_knives and buy the Gun Digest Assembly/Disassembly manual for sporting rifles. The Marlin 30-30 is in there.
Go to a sporting goods store or gunshop, and get a .22 caliber cleaning kit. Check the rifle to be sure it is completely unloaded. Open the bolt and pull it back. With the safety off, press and hold trigger, and slide bolt out of the rear of the action. Loosen the large screw forward of the trigger guard. This will release the action from the stock. STOP. Do not take anything else apart. Follow instructions in your cleaning kit.
this is a bolt action rifle

Best left to a gunsmith.
The Marlin firearms company produced pump action shotguns from 1898(the Marlin model 1898)all the way up to 1985(The model 120 Magnum shotgun).during that time span Marlin made 17 different model pump action shotguns.
I have looked at the bolt myself and have not found a way to do so. The takedown manual that you can get off the internet does not give you directions on how to do so. I am sure you know how to remove the bolt from the receiver: pull back bolt and squeeze the trigger and continue to pull back the bolt. If you are concerned about cleaning it, some Rem Oil and cotton swabs always do the trick.
Depending on condition, a Marlin 1895 lever action in 45-70 sells for $400-$500.
The marlin 1897 lever action 22 is valued at $555 in fair condition. In excellent condition, it is valued at $1,150.
