Read the General Procedures to prepare for seal installation, refer to section
4.3.1.
- Install lipseal (43) to flushed housing (44).
- During Pump assembly Install housing (44) to rotorcase securing with
screws (26) tightening to correct torque, refer to section 5.2. Ensure the
gasket or o-ring (27) is in place before tightening screws (26).
- Locate thrust ring (42) into rotorcase (item 40 see fig 5.6) to engage with
flushed housing (44). Ensure wave spring (29) is installed to thrust ring
(42). If only the seal faces are being replaced the housing (44) and thrust
ring (42) will already be in place.
- Install o-rings (32) into rotors (item 41 see fig 5.6).
- Install rotary seal faces (33) into rotors (item 41 see fig 5.6) ensuring that
the drive lugs and drive slots engage. Make sure the o-rings (32) are
located correctly and that the seal faces (33) are sitting squarely in the
rotors (item 41 see fig 5.6).
- Install o-rings (30) to stationary seats (31).
