Rather than reinventing the wheel, I thought others might appreciate what I learned when disassembling my 1887.
Cylinder Removal
Before complete dis-assembly, the “EMPTY” cylinder can be removed by turning the knurled ejector rod under the barrel counterclockwise (while looking at the revolver from the barrel end) a half turn. Retract the ejector rod until it and the sleeve around the barrel can be rotated up on the right side of the barrel. This allows the rod to eject empty cases from the cylinder. The cylinder “base pin” with two small wings under the barrel can then be withdrawn which will allow the cylinder to be removed from the right side of the frame after the loading gate is opened.
Complete Disassembly
1 - Remove the screw at “A” mentioned above and retain for use later.
2 – Lightly tap the left side of the trigger guard with a nonmetallic hammer untl the left side-plate comes loose. Remove and set aside.
3 – Inspect the interior of the left side of the frame and locate all the letters “B” through “H”.
B – Threaded hole under the upper arm of the main spring.
C – Hammer
D – Cylinder pawl
E – Trigger
F – Trigger guard
G – Lower tang of trigger guard at grip frame
H – Lower end of main spring.
4 – Cock the hammer enough to reveal the threaded hole at “B” and screw in the screw removed at “A”. Release the hammer and the screw will hold the spring out of the way.
5 – Cock the hammer enough for the entire cone shaped firing pin to be exposed and remove the hammer.
6 – Rotate the top end of the cylinder pawl “D” to the right and remove.
7 – Remove trigger “E”.
8 – Back out the screw in the trigger guard at “F”, while maintaining upward pressure on the trigger guard, to a point where the slotted trigger guard will rotate downward under main spring tension.
9 – Remove trigger guard at “G”.
10 – Remove main spring at “H”.
Assembly is the reverse order.
