Turn the center section over. Spread a thin film
of lubricant evenly across the o-rings on the main
and center assemblies (2 & 4). Be careful not
to plug the air holes. Put the center assembly
(4) inside the main assembly (2), and use an
appropriate-sized socket to press the sleeve
assemblies into the body.
6.
Lubricate and install an EPDM ring (36‡) into
the seat for the sleeve cap, in the center of the
body (1).

Apply medium-strength thread locker to the
threads of the second sleeve cap (3). Use the
tool (45) to install the second sleeve cap (3) into
the body. Tighten just until the cap is flush with
the surface. Do not overtighten.
