Does anyone have a link that talks about or shows the proper breakdown and cleaning and lubing of this rifle? I see videos that completely take it down. Is that required for regular cleaning and maintenance? Thanks

New Rossi 92s tend to have more than their fair share of gunk and metal chips in them so a detail strip and clean is a good idea on a new one, and while you've got it part replacing the ejector spring, the mag follower, polishing the cartridge guide and the lever detent makes sense, as does lightning the hammer spring and loading gate spring.    

After that, there's not much need for regular disassembly.  If you're shooting really light loads where the brass doesn't expand and seal the chamber, you'll get some gunk in the action, but otherwise it stays clean and brushing it out with some solvent now and then is sufficient after you've cleaned the bore.

Some folks will remove the stock and fore end and then liberally spray the action with an aerosol gun scrubber, then re-oil it with an aerosol gun lube and then stand it on it's tang and let it drip dry over night in a metal pan.  Once the excess oil runs out over night they put the word back on.   They'll do that in lieu of the initial cleaning of a new Rossi, and they'll do it as an annual cleaning of the rifle.

Personally, I don't find the Rossi to be hard to take apart for a detailed cleaning every year or so.  You cock the hammer and pin the hammer spring, remove the hammer screw, remove the lever pin, and take it apart.  There's no need to get into the minutia such as moving the cartridge guides or loading gate, and taking the cap off the magazine tube is all you need to do to remove those parts and thoroughly clean the tube.

Re-assembly has a few quirks, but it's not hard once you get the hang of it.  The only tricky part is getting the ejector assembly and spring in place in the bolt and then inserting the lever and locking lugs into the action so the lever properly engages the bolt and ejector.

Steve of Steve's Gun's (Rossi Specialist and CASS member) recommends in his DvD to just remove the buttstock and mag follower and spring, hold the muzzle upright, and spray brake cleaner down the barrel and mag tube with the action over a bucket to catch the dirt, grime, and cleaner.  Do this outside as brake cleaner isn't good for the lungs in a closed space.  Also, open action and spray it while cycling it to clean it out as well.  Be sure to avoid getting brake cleaner on the forestock as it will remove the finish.  After you've got it cleaned out, be sure to give it a oiling and lube to replace as every but is removed by the brake cleaner. 

I run a lubed bore snake down it a couple of times after every range session and about once every couple months or 500-600rds, I remove the buttstock and clean it out and then re-lube it.  That keeps the carbon and gunk cleaned out and after re-oiling and lubing the action, it's all smoothed up and ready for some more fun.

Most any lever gun all you have to do to keep them running is clean the bore and using q tips or pipe cleaners or toothbrush get what ever you can get to with the action open lube any rub spots and drive on. No need to ever disassemble for care unless you run into a problem
