7. Secondary Lock Installation
1.
Start the roll pin into the casting lug hole, opposite
where the cam plate is installed (Figure 16).
2.
Assemble the secondary lock to the torsion spring as
illustrated (Figure 16), then position and align between
the casting lug and the casting hole beneath (Figure
17). The spring flats must rest against the casting post
underneath the casting lug (Figure 17).
3.
Drive the roll pin through the casting lug hole, torsion
spring, and secondary lock, and then into the next hole
in the top plate casting until flush with the casting lug
(Figure 17).
4.
Check for proper spring tension and operation by
pulling the secondary lock out and allowing the spring
to snap it closed.
5.
Lubricate the post (roll pin) on the secondary lock where
it contacts the cam plate (Figure 16), with water-
resistant lithium-based grease.
