Note

Install a new slotted spring pin each time the old slotted spring pin is removed.

1. INSTALL DRIVE LEVER LOCK ON VERTICAL CAM.

a. Position the drive lever lock (1) on the vertical cam (2), so that the curved step on the drive lever lock is upward as shown.

b. Place the two ends of the drive lever lock in a vise. This keeps the ends of the lock from bending during step 2a.

2. INSTALL NEW SLOTTED SPRING PIN INTO VERTICAL CAM ASSEMBLY.

a. Using the hammer, tap a new slotted spring pin (3) into the aligned holes on one side. Guide the slotted spring pin as you continue to tap it in, until the slotted spring pin enters the aligned holes on the other side of the drive lever lock. Ensure the slotted spring pin is flush on both ends.

b. Install the vertical cam assembly and primary drive lever in the receiver.
