Remove crane lock screw (22) and crane lock (21). Swing out cylinder and remove cylinder and crane assembly by pushing to the front. Disassembly of the cylinder and cranc assembly should be undertaken only by a competent gunsmith.
Remove stock screw (39) and stocks (40). Remove sideplate screws (24). Do not attempt to pry out the sideplate (23) but tap the frame and sideplate with the wooden handle'of a tool until the plate loosens and can be lifted out. Remove the latch (25) and latch spring and guide (26 and 27) from the sideplate.
To remove the mainspring (15), lay the pistol flat and push the hammer back about 14" with the left forefinger. Holding a screwdriver in the right hand, press down on the mainspring near the stirrup (3) with the flat tip of the screwdriver. Push the hammer forward to disengage the stirrup from the mainspring and lift out the mainspring with the fingers.
Remove hand (12) from trigger (13). Drive out the rebound lever pin (20) with a punch or drift pin and remove the rebound lever (19). Remove the trigger by lifting it up off the trigger pin (14). Draw the hammer (1) to its rearmost position and lift it up off the hammer pin (2). Drive out the strut pin (7) from the hammer with a small punch and remove the strut (5) and strut spring (6). Drive out the hammer stirrup pin (4) and remove the hammer stirrup (3).
Remove the safety lever (11) from its pivot around the base of the hammer pin (2) and remove the safety (10) from its slot in the frame. Remove the bolt screw (18) and remove the bolt (16), using care not to lose the bolt spring (17). The latch pin (28) can be dropped out of its hole in the frame.
Removal of the barrel, firing pin, recoil plate, stock pin, trigger pin, or hammer pin should be attempted only by an experienced gunsmith.
The revolver is reassembled in the reverse order. The safety lever (11) should be placed back on its pivot with the slot in its short end engaging the stud on the safety (10). Replace the trigger so that the stud on the right side of the trigger engages the slot on the longer end of the safety lever. This assembly should be tested by moving the trigger back and forth to determine if the safety and safety lever are operating smoothly with the safety in its full "up" position when the trigger is all the way forward. The proper relationship of the safety, safety lever, trigger, and bolt are shown in Fig. 1.
To replace the mainspring (15), grasp the spring between thumb and forefinger of the right hand and slide the slotted end of the spring into position with the hammer stirrup (3), guiding the stirrup into position by moving the hammer on its pin with the forefinger of the left hand. When the stirrup and mainspring have been engaged, lift the bottom of the spring onto the rebound lever (19) with thumb of right hand. Replace hand (12) in its hole in the trigger and press upward on the rebound lever (19) to allow the hand to be fully seated. The sectionalized diagrammatic view in Fig. 2 shows these parts in their proper relationship.
Replace the latch spring and guide (26 and 27) in sideplate (23) and place sideplate in position on frame but do not seat fully. Place the latch (25) in its slot in the sideplate so that the stud on the latch pin (28) engages the hole in the latch. Seat the sideplate tightly and replace the screws (24). Replacing cylinder and crane assembly and the stocks completes the reassembly. -mt
