Mounting instructions Fig. 1
for Y-bearing plummer 1
block units
with a cast housing and an eccentric locking
collar
1 Mount any components that are on the
shaft between the two Y-bearing units.
2 With the eccentric locking collar removed,
slide the Y-bearing plummer block unit onto
the shaft with the locking device facing
outwards.
3 Position the Y-bearing unit on the support
surface. Fit the attachment bolts or nuts but
do not tighten them.
4 Mount the other Y-bearing plummer block
unit on the other end of the shaft, following Fig. 2
steps 2 and 3.
5 Carefully align both Y-bearing units, using
the shaft. Fully tighten the attachment bolts
or nuts in the housing base.
6 Align the shaft in the bearing arrangement
axially and – if possible – turn it a few times.
7 Place the eccentric locking collars on the
inner ring extension of both Y-bearing units
and snug tighten them in the main direction
of rotation († fig. 1).
8 Tighten the locking collars to their final
position, using a hook spanner with a stud
engaging the hole in the circumference of
the collar († fig. 2).
9 Tighten the grub screw in the eccentric
locking collar of both Y-bearing units
(† fig. 3) to the tightening torque indicated
in table 1 on page 54. Fig. 3
10 If applicable, snap the end cover(s) into
