remove the extractor, insert a small tool to push the spring plunger rearward, and lift the extractor out of its recess. CAUTION: Control the plunger and spring, and ease them out.
12. The roll-pin in the lower edge of the bolt is only a bearing pin for the cartridge lifter, and it need not be removed in normal takedown.
13. Remove the ejector plate from the left side of the trigger group.
14. Move the safety to off-safe position, restrain the hammer, pull the trigger, and ease the hammer down to fired position. Unhook the disconnector springs (one on each side) and allow them to go over toward the rear. (Note: The Colt parts list calls the disconnector the “sear bar”)
15. Remove the disconnector cross pin toward either side.
16. Restrain the sear, and remove the sear cross pin toward either side.
17. Move the disconnector slightly rearward, and take it off upward.
18. Tip the sear over toward the front, and remove it through the side opening.
19. Remove the sear plunger and spring.
20. If necessary for repair, the disconnector springs can be removed by prying out their mounting posts on each side. These are usually fitted very tightly, so routine removal is inadvisable.
21. Drift the hammer spring pin alternately toward each side, just far enough to allow unhooking the spring. CAUTION:Even with the hammer in fired position, the spring is under tension, so control it. When it is unhooked on both sides, move the spring to the rear and turn it for removal.
22. Drift out the cross pin that pivots and retains the hammer and trigger, and remove the hammer upward. Note: Drift out this splined pin toward the left side.
23. Drift out the hammer stop pin toward the left, and remove the trigger upward. As with all pins that are splined, check to be sure that some previous disassembly has not reversed them.
24. When the trigger is removed, be sure the small nylon bushings are still present in both sides at the pivot point. If not, retrieve any missing bushing from inside the trigger group.
25. The trigger spring is mounted at the center on the hammer spring cross pin, and drifting out the pin will free it for removal, if necessary.
26. Drifting out these two pins will free the two sides of the cartridge feed throat for removal upward. In normal takedown, this system is best left in place.
27. Removal of the feed throat assembly will allow the cartridge lifter to pivot over rearward, easing the tension of its spring. The lifter and its spring are retained by this cross pin. Do not attempt to remove the lifter and spring without first taking off the feed throat assembly. (It is still in place here.)
28. If removal of the safety is necessary, insert a very small tool through the access hole in the safety to depress the detent plunger, and move the safety out toward the left side. Caution: The plunger and spring will be released as the safety clears, so take care that they are not lost. The tool used must have an offset tip with a reach of at least 5.16-inch. A dental tool is being used here. The hole is accessible only with the button in off-safe position.
29. The barrel is retained in the receiver by a large roll-pin. If removal is necessary, after the pin is drifted out grip the barrel in a padded vise and use a hammer and a block of hardwood to drive the receiver off the barrel.
30. The outer magazine tube is best left in place, but if it must be removed, take out the cross-screw and take off the forward barrel band.
31. The front sight is retained by two vertical screws. The dovetail-mounted rear sight is drifted out to the right. The buttstock is retained by a through-bolt from the rear, accessible by taking off the buttplate.
Reassembly Tips:
1. When installing the hammer and trigger, be sure the lower end of the hammer is inside the top of the trigger, to ensure that the nylon bushings are not dislodged. When inserting the pin, take care that the bushings are not damaged. When the hammer spring is moved back into place, use pliers to fit the spring loops back onto the ends of the cross pin on each side.
2. When positioning the sear for insertion of the cross pin, use a tool to depress and hold the sear plunger and spring. This is best done with the trigger group held gently in a padded vise.
3. This view shows all of the trigger group parts in their proper positions. Remember to place the bolt on top before reinsertion into the receiver. As the group is moved upward into place, use a tool at the center of the cocking handle assembly, inside, to push it back slightly for re-engagement with the bolt recess. Do not use the bolt handle for this.
