21. Remove the lock screw and the large carrier pivot screw on each side of the receiver.
22. Remove the two sections of the carrier down-ward. Note that on early guns. the carrier will be a single part.
23. The dog and its plunger and spring are retained on the rear section of the carrier by a cross pin that is riveted in place, and this should be removed only for repair. If it is necessary, drift out the pin inward (toward the left), and be sure the carrier section is well supported.
24. Restrain the bolt spring plug at the rear of its housing, push out the cross pin, and remove the plug, spring, and follower toward the rear. Caution: The spring is powerful and is under tension. Control it, and ease it out It is possible to also unscrew the housing (tube) from the rear tang of the receiver, but this is not advisable in normal takedown.
25. Move the bolt back to the position shown, until the locking block latch pin is aligned with the exit cut in the lower edge of the ejection port. Insert a drift punch through the access hole in the left side of the receiver, and push out the pin toward the right.
26. Removal of the pin will release the locking block latch from the bottom of the bolt. Remove the latch and its spring.
27. Move the bolt to the rear, swinging the link bar out-ward. Restrain the operating handle, and move the bolt forward, leaving the handle at the rear.
28. Swing the link bar back inside, and remove the bolt assembly toward the front.
29. Move the operating handle unit forward, and remove it from the ejection port.
30. Drift out the cross pin at the rear of the bolt toward the right, and remove the firing pin toward the rear.
31. Push the front of the link bar upward, tipping the locking block out the top of the bolt, and remove the assembly upward. Drifting out the cross pin at lower rear of the locking block will release the link bar for removal.
32. The extractors and their coil springs are retained on each side at the front of the bolt by vertical pins. Drift out the pins downward, and take off the extractors and springs toward each side.
33. Remove the magazine cut-off spring screw, located on the left side at the forward edge of the receiver, and take off the spring toward the front.
34. On early guns, the magazine cut-off, carrier latch, and shell stop are retained by vertical screws set in the lower edge of the receiver. In later guns, such as the one shown, these parts are retained by roll pins. For removal, the pins are drifted upward, and exit holes are provided inside the receiver. Use a roll pin punch to drift the magazine cut-off pin upward.
35. Remove the magazine cut-off toward the left.
36. Drift out the shell stop pin upward, and remove the shell stop and its spring from inside the receiver.
37. Drift out the carrier latch pin upward, and take out the latch and its release button from inside the receiver. Note that the carrier latch spring is riveted in place, and is not routinely removed.
38. Insert a screwdriver in the open center of the magazine spring retainer, and pry the retainer out, moving the screwdriver to raise it equally around its edge. Caution: The magazine spring is under tension, so control the retainer and ease it out. Remove the spring and follower toward the front. Removal of the magazine cut-off spring screw will have freed the magazine tube, and it can be unscrewed from the receiver.These are tightly fitted, though, and are best left in place in normal takedown.
Reassembly Tips:
1. When replacing the pivot pins for the carrier latch, shell stop, and magazine cut-off, drive them in the same direction they were removed, upward. Take care that the parts are properly aligned before driving the pins into place. Insert a drift punch to insure alignment, then hold the parts in place with a fingertip while the pins are inserted. Be sure the pins are not driven too deeply, as their upper ends can enter the bolt track.
2. In the later guns that have the two-piece carrier, the parts may be difficult for the amateur. In this photo, the parts are shown in the proper position.
3. When installing the combination trigger and safety detent spring, use a tool to depress the spring at the cross pin location, and insert a drift punch to hold the spring down while putting in the cross pin. It will be necessary to depress the spring on the other side as the pin is inserted, and the end of the cross pin must also be depressed as it enters the hole on the other side of the tang.
4. When installing the trigger group in the receiver, insert the group as shown, replacing the rear cross screw first. As the group is swung СКАЧАТЬ
