 Field-stripping The Winchester/Miroku 1886 TutorialBy: Steve BarrettThe following is not new information, or information that cant be had from a firearms disassembly book, but I have not found any information with pictures of the process as far as field-stripping the Winchester/Miroku 1886. I also ordered a video from AGI(American Gunsmithing Institute) on the 1892/1886 Winchesters. I am already familiar with the 92 design, so I bought the video just for the 86 material. The video mentions nothing or shows nothing on the procedures of field-stripping the Winchester 1886. I thought it might be helpful to those who own these fine leveractions to have a field-stripping tutorial, (some body's gotta do it! :roll: ). I hope this helps and I sure had fun putting it all together....Steve. P.S. This contains lots of photos and may load up slow, so please be patient STEP ONE: Remove the upper and lower tang screws and pull buttstock straight off the rear of the receiver. The upper tang screw goes all the way through and screws in the bottom tang. The lower tang screw is a wood screw.   STEP TWO: With the action closed pull the hammer to rear and remove the receiver (hammer) screw. You want to captivate the mainspring before removing the receiver (hammer) screw. This coil mainspring is strong and may fly to the next room if not held in place. You can use a paper clip or similar item to hold the mainspring in place.  STEP THREE: After removing the receiver (hammer) screw, open the lever and pull the lower tang straight back out of the receiver. At this time the hammer will drop out as well. Pictured below is the hammer and lower tang assembly. The trigger assembly was not taken apart  |

ACTION DISSASEMBLYSTEP ONE: Remove the Spring Cover Screw from the right hand side of the receiver.  (SPRING COVER ASSEMBLY) STEP TWO: Unscrew the carrier stop screw and remove the carrier stop from underneath the upper tang.  STEP THREE: With the action part way open, unscrew the locking bolt stop pin screw from the left locking bolt. This will allow the locking bolt pin to be pushed out of the lever and locking bolts from right to left. Now pull out both locking bolts from bottom of receiver  If you have trouble pulling the right locking bolt out of the bottom of the receiver, move the cartridge guide up or down, whichever is necessary, to allow the locking bolt to be pulled out.  STEP FOUR: Lower the finger lever and slide the Breech Bolt out of the receiver far enough to see the lever and Breech Bolt Pin. Use a punch to drift out the Breech Bolt Pin out of the Breechbolt.  After removing the Breech Bolt Pin, pull lever out of the bottom of the Breechbolt and slide the Breechbolt out of the receiver. Be careful when pulling out the Breechbolt as the Ejector, Ejector Spring, and Ejector Collar is now loose and can fall out the front of the Breechbolt. Once the Breechbolt is out of the receiver remove the Ejector, Ejector spring, and Ejector Collar out the front of the Breechbolt.  (BREECHBOLT ASSEMBLY)

The firing pin is of the inertia type and can be removed by using a punch to drift out the Extractor pin. Once the Extractor pin and Extractor are removed the inertia firing pin can be pulled out of the rear of the breechbolt.  STEP FIVE: Slide the Lever, Carrier Hook and Carrier out the back of the receiver. Notice how these parts go together for reassembly. The Carrier Hook connects the Lever And Carrier by the lower hole in the lever and (rides in the middle of the Carrier) a channel cut out of the Carrier NOTE:For some reason I cant get this pict to load on the site here, but here the link to the pict...Stevei104.photobucket.com/albums/m193/stevensavage/86%20EL/86%20Fieldstrip%20tutorial/lever_carrierhook_carrier.jpgI didn’t take the rifle down any further, but if need be you can remove the Cartridge Guide and Cartridge Stop from the receiver. To remove the cartridge guide simply unscrew the cartridge guide screw from the right side of the receiver and remove the Cartridge Guide from inside the right hand side of the Receiver  To remove the Cartridge Stop, unscrew the Cartridge Stop Screw from the left side of the receiver.  (The Cartridge Stop is highlighted in the picture below.) |

Now to get all these parts back in the ’86!  REASSEMBLYReassemble In Reverse Order To get the Lever, Carrier Hook, and Carrier to stay together for reassembly it is much easier to use a rubber band to hold these parts together. If not, you can become frustrated in short order. STEP ONE: Slide the Breechbolt assembly partway into the receiver. Slide the Carrier, Carrier Hook, and Lever into the rear of the receiver.  Lineup the Lever and Breechbolt and insert the Breechbolt Pin into the Breech Bolt. You will need to make sure the firing pin, and Ejector is both pushed in far enough into the bolt, and that the lever is lined up at the same time so the Breechbolt Pin can be pushed into the Breechbolt. Fun isn’t it? This is just about the time you wished you had a third hand, but in no time you will have these lined up and the Breechbolt Pin inserted. (Lever and Breechbolt pin hole lined up and Breechbolt Pin inserted)(NOTE: again, this pic would not load up for some reason, so here is the link to the pic....Steve)i104.photobucket.com/albums/m193/stevensavage/86%20EL/86%20Fieldstrip%20tutorial/REcartridgeguidemovement.jpgSlide the Breechbolt, Lever, and Carrier on in the receiver. Once you get these parts into the receiver far enough discard the rubber band. Now on to the Locking Bolts. STEP TWO: Insert the Locking Bolts in from the bottom of the receiver and install the Locking Bolt Stop Pin and screw. Again if you have problems inserting the right Locking Bolt, move the Cartridge Guide up or down whichever is necessary to allow the right Locking Bolt to go up into the receiver. The right Locking Bolt has a groove cut into it to move the Cartridge Guide up and down while the action is cycled.  STEP THREE: Install the Spring Cover Assembly. STEP FOUR: Install the Carrier Stop and Carrier Stop Screw to the underside of the Upper Tang  STEP FIVE: Install the Hammer and Lower Tang Assembly back in the rear of the receiver. Again this is somewhat of a juggling act and a third hand could come in handy at this point. You need to keep the Lower Tang pressed in while making sure the Trigger is pulled back while aligning the holes in the Hammer and Carrier. Use a punch to help align the parts.  When you get the Receiver Screw pushed halfway in take a punch and align the carrier so the Receiver Screw can be pushed on in and screwed in the Receiver. If you removed the Mainspring during this process it needs to be captivated. An easy way to captivate the Mainspring for reassembly is to install the hammer in the Lower Tang outside the Receiver, then insert the Receiver (Hammer) Screw into the Lower Tang, then allow the Hammer to fall as far forward as possible and insert the Mainspring and Hammer Strut in the Lower Tang. Pull the Hammer back compressing the Mainspring. Once the Mainspring is captivated, pull the Receiver (Hammer) Screw out of the Lower Tang. (Thanks for the tip Griff!) STEP SIX: : Install the Buttstock.  |
