Disassembly:

1. Back out the barrel retaining screw, located just forward of the lever on the underside of the gun. On guns made after 1915, the head of the screw will be a knurled piece, rather than a ring.

2. Remove the barrel and forend assembly forward.

3. The forend is held on the underside of the barrel by a single screw.

4. Remove the screws at the rear tip of the upper and lower receiver tangs to release the stock for removal. Remove the stock toward the rear. If the stock is very tightly fitted, it may be necessary to bump the front of the comb with the heel of the hand or with a soft rubber hammer.

5. The screw that retains the hammer spring can be reached through the stock screw hole in the upper tang. Remove the hammer spring screw and take out the spring toward the rear. On the post-1915 guns, the hammer spring will be a heavy coil with an internal hammer strut and a base sleeve at the rear, which bears on a groove in the head of a large screw in the lower tang. On these guns, grip the sleeve firmly with pliers and move it forward, and then upward to clear the base screw. After the hammer spring is removed, in both models, the screw which retains the trigger spring will be accessible. For this screw, use either an offset screwdriver or a screwdriver with the tip cut to an angle.

6. Taking out the hammer and trigger pivot screws will release the hammer for removal upward and the trigger for removal downward.

7. Remove the lever pivot screw, located at the lower edge of the receiver.

8. Remove the breechblock pivot screw.

9. Remove the lever and breechblock assembly downward. The ejector, which is retained by the lever pivot screw, will also come out at this time.

10. The ejector on the later model guns is different from the one shown. On the post-1915 guns, it has a front lobe which contains a plunger and spring, the plunger bearing on the breechblock pivot. The plunger is staked in place, and removal in routine disassembly is not advisable. Drifting out the upper cross pin in the breechblock will release the firing pin for removal toward the rear. The lower cross pin holds the link to the breechblock, and the pin at the top of the lever retains the lever on the link.
