4. Rotors and Bearing Housing Assembly - Gear End
Bearing housing must be oriented so that dowel holes in bearing housing lines up with dowels in air
cylinder.
13.
From
the
blower
model
designation,
determine
drive
shaft
(long
rotor)
location
and
the
direction
it
rotates.
14.
Insert
rotors
(2)
into
the
cylinder
individually
using
an
overhead
hoist.
Verify
that
the
long
end
of
the
drive
rotor
extends
through
the
drive
end
bearing
housing
and
that
it
is
in
the
correct
bore.
Ensure
that
the
rotation
of
each
rotor
matches
the
arrows
on
the
outside
of
the
air
cylinder.
Ensure
that
rotor
lobes
match
the
triangular
shape
of
the
discharge
port.
15.
Measure
and
record
the
total
rotor
to
bearing
housing
end
clearance
for
each
rotor.
This
is
accomplished
by
using
a
depth
micrometer
to
measure
the
distance
from
the
top
edge
of
the
air
cylinder
to
the
top
of
the
rotor
lobe
while
the
rotor
is
supported
by
the
bottom
bearing
housing
and
held
as
vertically
as
possible.
16.
Apply Loctite Gasket Eliminator 515 (50) to the
sealing surface of the cylinder and install two dowel
pins (27) into the cylinder. Install the bearing housing
(3) onto the cylinder using two socket head bolts
(31), four hex head bolts (38) and four lock washers
(32).
17.
Tighten bolts (31) to 110lbs. and (38) bolts to
75lbs.
