Removing the bolt to have it Micro Slicked (Dry film lubricant) and figured I would take some pictures and try and write something up. I will work on pictures putting it back together once I get my bolt back. Let me know if you have any questions or anything you would like me to add.
My 1970's Rossi m92 Chambered in .357 and .38.

1. Unscrew the tang screw and remove the butt stock.
Image

2. Slowly pull back the hammer until the small hole in the main spring rod is visible in the 'V' of the main spring rod block. Insert a pin or needle into the hole to retain the main spring.
Image
I used a safety pin. A paperclip is to weak and the spring will bend it, and it will be a Royal pain in your %@*&$ to get it back out.
Image

3. Remove the bolt pin stop screw.
Image
4. Tap it out from the opposite side. This is a PIA if you forget...

Here it is uncovered:
Image

5. Swing down the lever and open the bolt. Be careful not to lose the ejector, ejector spring, and ejector collar. These will protrude from the front of the bolt assembly. Carefully remove these parts from the front of the bolt.

6. Remove the locking bolt stop pin screw from the left locking bolt.

7. Remove the locking bolt pin.

8. Remove the lever:

9. Remove the hammer/lower tang screw.
10. Place your index finger on the rear of the lower tang. Compress the trigger with your thumb, and remove the lower tang by pulling straight back from the receiver.

Image

11. Remove the hammer assembly.
12. Remove the bolt assembly.
Image
Image

Next you can remove the carrier screws and remove the carrier. However, I didn't.

Once I got the bolt out I needed to remove the ejector and the firing pin with a very small punch.

Here it is with the ejector removed:

Ejector and firing pin removed:

All of the parts laid out:

*I took the steps from here: http://marauder.homestead.com/files/RossiDis.html

I will be getting my bolt Micro Slicked by Greg at http://www.BandECoatings.com
I have already had the BCG done in my AR15 and it is awesome, plus Greg is a great guy to do business with. I am also having it done in my 10/22 and the Rossi because I don't plan on ever taking it apart again and it will slick up the action, smooth out all of the tooling marks on the bolt, and it makes it really easy to clean! :D

can you post pics of the bolt after you get it back curious as to how it will look when finished before you put it back into the gun.

Thanks. Each disassembly post like this increases my confidence to tackle my own.

Go for it and if you run into any issues and I don't have her put back together yet I will take some pictures for you on what you need to do.

Great thread. I've previously used a grainy photo, semi-descriptive set of instructions.

Makes you wonder cowpokes cleaned their Winchesters. If they did!

A lot of the old timers I remember as kid didn't clean their guns as often as we do now. They might drop some 3 in 1 oil into the action and work it a bit to loosen things up, but that was about it. I think my Grandpa would wipe out the barrel with an oiled piece of rag on a straightened out clothes hanger once a year whether it needed it or not and drop a little oil into the action. The most cleaning I remember was an uncle of mine taking a Colt single action apart and dropping the parts into a coffee can of gasoline.

Got my bolt back all nice and slicked. Another cool thing is Greg went though it and cleaned up some all of the pitted rot/rust that was in it. So she is good as new. Now I just need to put it all back together! :|

Thanks from a Rossi 92 "newbie" for taking the time to photograph each step of the disassembly process! That refinished bolt looks great, BTW. Tt.
