25.
Engage serrations (9) of fitting (6) with proper
wrench from table 1. Tighten fitting to minimum
torque from table 2. Make sure serrations of
Rosan fitting align with serrations in port.
NOTE
Upon reinstallation of original Rosan
fitting, index marks should align.
26.
If serrations of lockring (1) and port (8) do not
align, slowly increase torque toward maximum
until serrations align. Do not exceed maximum
torque.
27.
Clean port hose. Use solvent (E162).
28.
Apply enough zinc chromate primer (E291) to
port (8) and below fitting lockring (1) so primer will
squeeze serrations during lockring installation.
29.
Install reducer lockring (1) while zinc chromate
primer is still wet as follows:
a.
Select proper size lockring drive tool
RF98-DEK from table 1.
b.
Place drive tool over reducer (14). When
properly located it will rest on lockring (1).
c.
Set lockring (1). Use a hammer, arbor press,
or hydraulic press. Installation is complete
when tool bottoms on surface of port (8).
