3. Assemble gear headplate (18) and mounting foot
(17) to the impeller case with cap screws (21) and
where the mounting foot is secured to the head-
plate use capscrews (16). The two positioning
dowel pins (19) will ensure proper alignment of the
headplate and impeller case. Also secure lifting
lugs using capscrews (21) (see exploded assem-
bly drawing page 25). Torque capscrews alter-
nately and evenly. Refer to FIGURE 25, page 24,
for torque specifications.
4. Apply a light oil or grease on the shaft seal areas
and the bearing areas. Insert impellers into the
gear headplate using the same headplate bores
as used in the original assembly.
Seals are delicate; use extreme care
when installing impeller shafts in the
headplate bores. A piece of light shim
stock wrapped around the shaft key-
way will prevent cutting the seal lip.
5. Position blower so that impellers are vertical, with
the drive end on top. It will be necessary to use
blocks in order for the unit to set level. Measure
the total end clearance using a depth micrometer
(see FIGURE 19).
If total clearance is not within the limits specified
in FIGURE 21, page 20, it may be necessary to
shim the case to obtain the proper total end clear-
ance. The shim should be placed between the
drive headplate and impeller case.
If more than .007” shim is required,
put .007” on the drive end and the re-
maining on the gear end.
6. Assemble drive headplate (24) to impeller case as
done in step 3 with the gear headplate. If shims
were required, place shims between drive head-
plate and impeller case.
MECHANICAL SEALS ONLY
A. Refer to FIGURE 18, page18. Lightly coat
the impeller shaft (H) and the inside diameter
of the mating ring (B) with assembly lubri-
cant.
B. Install the mating ring (B) on the shaft only far
enough to get the bearing (E) started on the
shaft.
C. Lightly lubricate the bearing inner race (E)
with a light oil or grease.
Do not drive the mating ring down to
the mechanical seal, as this can dam-
age the seal.
D. Using a press, install the bearing on the shaft
with the bearing driver shown on page 14.
