fixed position of the rotor. This is an important
step in the assembly. The best method for tighten-
ing the nuts is with a wrench of the type shown in
FIGURE 3, Disassembly, page 23. Install the
gate rotor shaft clamp plate (11) and tighten three
screws (41) progressively to pull the assembly
tight as described above. Note the retainer is
installed with the pilot up to prevent marring of the
oil slinger side.
19. Check the discharge end clearance of the rotor
with a feeler gauge through the discharge
opening, FIGURE 19, page 34. Also check rotor
end clearance at the inlet end through the inlet
opening. Clearance should match those listed in
the chart, FIGURE 7 - 8, page 35, keeping in
mind the allowable tolerance and possible .002
”
variation in rotor lengths. Never allow rotors to
run closer than allowable tolerance. Wider
clearance will not result in blower failure but may
affect efficiency. If the discharge end clearance
is too great, make sure the bearing retainer plate is
tight, holding the bearing solidly in the bore, and
the bearing retainer nuts are tight, which clamp
shims and bearing spacer solid against the end
of the rotor, Step 18. If clearance is too close,
remove the discharge end carrier and repeat the
steps to establish shaft shim sets and total end
clearance.
20. Bend the ear of the lock washer (27) into the slot
of the nuts (26) on the main rotor shaft extension.
Oil the bearing generously. Remove the gate rotor
retainer plate (11) and install with the pilot side
down in the bearing inner race. Place the oil
slinger (6), with reinforcing plate up, FIGURE 20,
on the retainer plate and pull the assembly tight
with three
“Nylok” type screws.
21. Check the shaft extension and keyway for burrs.
Install keyway tool. Push the oil seal
(22) on to the shaft. Install the seal
adaptor gasket (44), to the end cover (12) and
using four screws (37). Slide the end cover over
the shaft extension (FIGURE 7 - 21) and mount
the cover to the bearing carrier with screws (39)
and washers (43). Remove the keyway tool.
Drive dowels (35) into end cover/bearing carrier
holes. Expulsion port on the seal should be
positioned down, install and tighten temporary
bolts. Rotate shaft 6 times. Replace temporary
bolts with nylon bolts and tighten. Install drive
key (33).
