NOTE
Only remove the protective wrapping of the seal faces immediately before assembly
takes place.
1. Insert the mating ring and the secondary seals of the mechanical seal into
mating ring carrier 476 and slide them onto the shaft from the pump end.
2. Slide the rotating components of the mechanical seal (torque-transmitting
element, springs, primary ring, secondary seal, etc.) onto the shaft as a complete
sub-assembly.
3. For LP02 and LP03: The mechanical seal is correctly positioned on the shaft when
its pump-end face (see "2" in Fig. "Installing the mechanical seal") is aligned
with the mark on the shaft (see "1" in Fig. "Installing the mechanical seal").
On shafts without marking, align the mechanical seal with the shaft shoulder.
The mechanical seal is generally positioned correctly when the bolt head is
located in the centre of the slotted hole (marking) (see Fig. "Correct position of
KSB mechanical seal" )

4. Tighten the grub screws with cup point evenly, alternately and gradually to the
torques specified, depending on the nominal thread diameter.
Grub screws with cup point may be used without applying a thread-locking
agent. Grub screws with cup point must not be re-used.
