      20. Move the bolt latch slightly rearward, and slowly release the hammer spring tension. Remove the hammer spring and plunger upward.

      21. Remove the rear cross-pin sleeve and take off the right sideplate. Note that the front of the sideplate the primary shell stop, and that it has a tab that engages a recess inside the front extension of the trigger group housing.

      22. Move the carrier assembly forward, and tip it downward for removal. Note that the carrier dog retaining pivot is held in place only when in its slot in the group housing, so take care that it doesn't fall out.

      23. Turn the carrier over your hand, and the dog pivot will fall into your palm. The dog can now be taken off.

      24. Remove the carrier plunger and spring.

      25. Push out the trigger cross pin.

      26. Remove the trigger assembly upward.

      27. Detach the trigger spring from its stud on the dis- connector. urn it clockwise (top view) to remove it from the trigger stud.

      28. The disconnector is easily lifted off its pivot pin on the trigger. The pin should be left in place.

      29. Use a small tool to push the bolt latch spring retaining pin outward for removal. Restrain the spring, as it may or may not fit tightly in its recess.

      30. Remove the bolt latch spring, moving it forward and upward.

      31. The bolt latch can now be removed upward. Because its lower tip is angled slightly outward, it will have to be gently pried.

      32. Restrain the sear, and push out the sear cross pin.

      33. Remove the sear and its coil spring upward.

      34. If removal of the manual safety is necessary for repair, put the button in on-safe position, and insert a small tool with an L-shaped tip, such as the dental tool shown, to depress its plunger and spring. The safety button is then easily pushed out. Caution: Keep the plunger and spring under control.

      Reasssembly Tips:

      1. When re-installing the rear cross-pin sleeve, the trigger must be pulled slightly to clear.

      2. Insert the front cross-pin sleeve in small increments, getting it through the carrier arm, the bolt latch, the hammer, and so on. Remember to install the hammer spring and plunger before putting in the bolt latch.

      3. Remember that the bolt head must be compressed into the bolt body for reinsertion into the receiver. Be sure the lugs on the action slide bars mate properly with their recesses on the bolt.
