INSPECTION (Cont)
b. Check the oil seal rings,
carriers and collars for
wear and scoring.
NOTE
When a blower with lip type oil seals is being reconditioned, the installation of
new seals is recommended. Oversize oil seals and oil seal spacers are available
in the blower kit to replace the standard oil seals when the blower rotor shafts are
grooved.
c. Inspect the blower rotor
lobes, especially the
sealing ribs, for burrs
and scoring. Rotors must
be smooth for efficient
operation of the blower.
If the rotors are slightly
scored or burred, they
may be cleaned up with
emery cloth.
d. Examine the rotor shaft
serrations for wear,
burrs, or peening. Also,
inspect the bearing and
oil seal contact surfaces
of the shafts for wear and
scoring.
e. Inspect the inside surface
of the blower housing for
burrs and scoring. The
inside surface must be
smooth for efficient
operation of the blower.
If the inside surface of
the housing is slightly
scored or burred, it may
be cleaned up with
emery cloth.
