Turning over the auxiliary bolt
1. Remove the auxiliary bolt spring and the deadlocking spring.
See Figure 6.6.
2. Remove the auxiliary bolt from the case and turn it over.
3. Insert the auxiliary bolt into the case. The beveled portion of the
bolt should be pushed through the front of the case and the feet
should be resting in the slot.
4. Place the auxiliary bolt spring, bent shank up, onto the hollow post
on the deadlocking lever. Then place the deadlocking spring, bent
shank down, on top of the auxiliary bolt spring. The center of both
spring coils should rest around the hollow post.
5. Position the long, straight shank of the auxiliary bolt spring so it
rests between the solid post on the deadlocking lever and the hubs.
Position the short, straight shank of the deadlocking spring against
the U-shaped latchbolt rod support.
6. While holding the springs on the post, grasp the bent shanks of both
springs and fit them into the top groove on the auxiliary bolt. The
spring tension should push the bolt toward the front of the case.
