ASSEMBLY INSTRUCTIONS
Illustrations for Assembly Instruc-
tions are taken from various sizes of
CycloBlower. Minor variations in
construction of some parts should
not cause concern.
Numbers in parentheses ( ) refer to
key numbers in assembly drawings
on pages 23 and 24.
The CycloBlower
®
is manufactured with close toler-
ances for efficient operation. All parts must be handled
carefully to prevent burrs which will give false clearance
readings and/or cause rapid wear.
All parts and oil passages must be thoroughly cleaned
of dirt which will cause galling of close running parts.
Clean work area, washing tank, tools, and wiping rags
must be provided.
Refer to Parts List, Section 5, pages 24 and 25, for
sectional views showing complete assembly of parts.
The following illustrations are of a
standard blower with top inlet,
bottom discharge, main rotor dis-
charge end drive. Some variations
will be noticed in the following
illustrations for blowers of other
arrangements.
There may be cases where foreign materials have
entered the blower, or other causes have resulted in
galling of the rotor ends, carrier faces, rotor lobes, or
housing walls. Since the blower is designed with no
contact of parts within the rotor chambers, these parts
may be cleaned and polished for reuse unless galling
is severe. Reuse of parts severely galled may result
in loss of blower efficiency. All damaged parts which
have been reworked should be checked for run out
or warpage before reuse.
Assembly of the
“R” Series CycloBlower differs from
earlier models in the approach to installing the oil seals.
On previous models the installation of the lip seals into
the bearing carriers was the first step in the assembly
process. On the
“R” Series, the Impro seals are not
installed into the bearing carriers until after the rotors
have been assembled. This requires that the Impro
seal is slipped over the rotor shaft using an Impro
installation too.
1.
Oil the O.D. of the rotor shaft seals (15) to prevent
seizure and press into each bore of the inlet end
carrier (5) (FIGURE 1, page 28). NEVER
REUSE SHAFT SEALS. Refer to
“Rotor Shaft
Seals,
” page 22, for an explanation. A simple
press utiliz- ing a bolt and two bars, one across
the seal and one underneath across the bearing
bore, is an ef- fective method for installing the
seal. Tightening the nut on the bolt presses the
seal into place. Press the seal .010
” to .015”
below the face of the carrier to prevent the end of
the rotor from rubbing the end of the seal. A
simple method is to place a .010
” to .015” shim on
the end of the seal under the press bar which will
allow the seal to be pressed the correct distance
below the face of the carrier. Handle the seal with
care to prevent damage to the babbitt lining.
2.
To ease assembly in later steps, fit the bearing
spacers (14) to the seals (15) (Figure 7-2, page
338). Be sure there are no burrs on the spacer
O.D. and seal I.D. Spacer should be SLIP FIT
in the seal. A sloppy fit will cause excess air
leakage and decrease blower efficiency. Do not
drive the spacer through the seal as damage to
the babbitt will result. It may be necessary to
polish the high spots from the seal I.D. to allow
slip fit of the spacer. USE CROCUS CLOTH,
not emery cloth.
Never push the grooved end of the spacer through
the bearing oil seal as the lip of the seal may be
damaged. Apply Loctite 620 to the ID of the
bearing spacer. When the spacers are fitted,
slide them on the gear end shaft extension of the
rotors (2, 3)
