2. Figure 183 shows the rotor nut O-ring installed.
3. Apply a small amount of anti-seize to the shaft threads, then
install the rotor nut.
4. Repeat these steps for the second rotor.
5. Insert the rotor blocking tool (part number 139790+) to keep
the rotors from turning when installing the rotor nuts.
NOTE: When working on a rotor, always block the rotor
against the body, not against the other rotor. See Figure 185.
NOTE: SPX FLOW recommends using the Non-Marring
Socket Tool for Rotor Nuts (see below) to protect the rotor
nut when torquing.
