13. Install the cylinder plug assembly (5) into the cylinder sleeve assembly (4). There is a slight interference fit between the cylinder plug and the
cylinder sleeve assembly, so be sure that the cylinder plug is fully seated into the bottom of the cylinder sleeve. The cylinder plug should be
slightly below flush with the inner face of the cylinder sleeve. Once the cylinder plug assembly is fully installed into the cylinder sleeve assembly,
the tumblers (8) will be fully enclosed and retained.
14. Install the actuator (11) into the pocket in the front face of the cylinder plug.
15. Install the security plate (10) on top of the cylinder plug in the cylinder sleeve assembly.

16. Securely stake the security plate (10) into the cylinder sleeve assembly (4) by using the BO-47869. Assemble the cylinder sleeve assembly,
security plate, and BO-47869. When loading cylinder sleeve assembly into the staking tool, ensure staking cup number 12 is positioned cup
toward cylinder sleeve. Secure assembled staking tool in a vise. Rotate the forcing screw (13) in order to uniformly stake the cylinder sleeve
material over the security plate.
Tighten the forcing screw (13) to 23-28 N.m (17-21 lb ft). Once the security plate has been staked to the assembly, ensure the actuator (11)
can rotate freely inside the assembly by inserting a key and removing it.
