4.3.2 Coat all sleeve O-rings with
silicone lubricant and install
them onto the sleeve. See
Figure 11.
Note: Earlier versions of the P-50
utilized a different pin drive design
which does not require O-ring. If the
pin in the sleeve is not grooved for an
O-ring, the O-ring will not be used.
Note: If Duraflon encapsulated
O-rings are to be installed, contact
your local Flowserve repair facility for
proper installation.
4.3.3 Install the rotor onto the sleeve
aligning the drive slot with the
pin. See Figure 12.
4.3.4 Install the rotor retaining ring.
Be careful not to nick, scratch or
damage the rotor face.
4.3.5 Place the sleeve/rotor assem-
bly rotor face up and clean the
face with alcohol.
See Figure 13.
4.3.6 Install new springs into the
stator, clean the stator face
with alcohol and place it down
onto the rotor. Be sure the
springs are placed in the proper
(deeper) holes. See Figure 14.
