ROTOR CASE ASSEMBLY
10. IMPORTANT!
During the following operations, take care you don't
damage the lapped seal surfaces; don't lay them
on the bench and handle them with clean hands.
11. Clean carefully the shafts. Be sure the spacers for
the seals are set (295). Lubricate lightly the O-rings
and insert the rotating part of the seals on the shafts.
Exert pressure only with hands; avoid using metal
tools.
12. Be sure the mechanical seals stand on the shaft
shoulder and tighten by degrees the socket head
screws. We suggest you should use a thread locking
adhesive in order to avoid their untightening on
work.
