2.5 Axial locking device adjustment
2.5.1 If the "X" dimension shown on Table 2 could not
be achieved /- 0.250 inch (6.4mm), the
axial locking device has a provision to accommodate
this variation.
2.5.2 Position the motor shaft on its magnetic center and
measure the gap between the faces of the drum hub
and spider ("X" dimension on Table 2). The difference
between this measured dimension and the value
shown on Table 2 is the amount of correction to be
made with adjustment of the axial locking device.
2.5.3 Referring to Figure 5, the overall length of the axial
locking device can be adjusted by relocating spacers
(11 / 17) from one side of a bearing to another.
2.5.3.1 Remove four hex head screws and lock washers
(6,7) from the bearing housing (8) and adapter
plate (1 or 9).
2.5.3.2 Remove the snap ring (2) from the bearing housing.
2.5.3.3 After ensuring the shaft (3) is clean and free of
foreign matter, nicks or burrs in the area between
the two bearing housings, slide the bearing housing
assembly toward the opposite bearing housing
assembly to expose the bearing/spacer
assembly (10,11,17).
2.5.3.4 Remove the bearing locknut and lockwasher (13,14)
from the shaft.
2.5.3.5 The assembled length of the axial locking device is
established by the location of the bearings with
respect to the shaft. The assembled length can
therefore be adjusted by moving spacers from
one side of the bearing to the other. Two
thicknesses of spacers are included in each
assembly 0.025 inch (0.6 mm) and 0.098 inch
(2.5 mm). After making the appropriate assembled
length adjustment, reassemble, making sure the
thinner spacers are against the bearing.
2.5.3.6 Tighten the locknut sufficiently to take up all axial
clearance in the bearing/spacer/snap ring assembly.
2.5.3.7 Slide the housing back over the bearing and install
the snap ring.
2.5.3.8 Secure and tighten the bearing housing to
the adapter plate using four hex head screws
and lockwashers. Tighten the screws to
35 ft.-lbs. (47 Nm).
2.5.3.9 After completing assembly, lubricate both bearings
with No. 2 EP grease.

2.6 Installation of element and drum (dual wide)
2.6.1 Separate the shafts as far as the bearing clearances
will allow.
2.6.2 Attach the drum having the female register on
the drum flange to the drum hub with short screws
and lockwashers. There are tapped holes in the drum
flange to accept the screws. Make sure the bore in
the drum flange fully engages the pilot on the drum
hub. See Figure 3.
2.6.3 Disassemble the dual element into two halves
and, noting the orientation of the air connections,
place the element onto the drum installed in 2.6.2.
2.6.4 Noting the orientation of the flange on the remaining
drum with respect to tie air connections on the
remaining element, slide the drum into the element.
