4.6.8 Check point - Disc stack
pressure
This check will ensure that the number of discs in
the bowl is correct, so that two conditions have
been fulfilled:
• The disc stack pressure is sufficient.
• Bowl hood and bowl body are securely
attached to each other.
NOTE
Ensure that the disk stack pressure is
sufficient to maintain bowl balance.
Insufficient pressure in the disk stack can
cause vibration and reduce life of ball
bearings.
Assumptions:
• The wear on the lock ring joint has been
checked. See “4.6.7 Check point - Limit for
thread wear” on page 104.
• The position of the 0-mark on the lock ring
has been marked with a marker pen (only
applies if the 0-marks are
not
exactly aligned
with each other).
• All parts of the bowl have been cleaned.
• The sliding bowl bottom and distributing cone
are in place.
Procedure:
Insert the complete disc stack in the bowl. The
distributor fits into the guide pin and locked so
that it cannot be turned in relation to the bowl
body.
Remove the lifting eye from the distributor. Place
the bowl hood in position. Make sure that the
groove in the hood fits into the guide pin in the
bowl body. The bowl hood should drop down over
the guide pin. Don’t remove the bowl hood lifting
tool.
Place the large lock ring on the bowl. Fit the lock
ring tool on the lock ring and tighten the lock ring
by hand.
