INSPECTION (Cont)
a. Rotors
Dirt or chips drawn thru
the blower will make deep
scratches in rotors and
housing and throw up burrs
around such abrasions. If
burrs cause interference
between rotors or between
the rotors and the housing,
remove the blower from the
engine and dress the parts
down to eliminate the inter-
ference, or replace the
rotors if they are too
badly scored.
b. Oil
Leaky oil seals are us-
To correct any
seals
ually manifested by the
of the above
presence of oil on the
conditions, re-
blower end plates and
move the blower
rotors or the inside
from the engine
surfaces of the housing.
and replace it.
This condition may be
checked by running the
engine at low speed and
directing a light into
the rotor compartment
at the end plates and
the oil seals. A thin
film of oil radiating
away from the seals is
indicative of an oil
leak.
