(15) Remove the two fillister head screws (27)
securing the rear end plate (7) to the blower
housing (28) and loosen the two fillister
head screws securing the front end plate to
the blower housing approximately three
turns.
(16) Back out the center screws of pullers
J6270-31 far enough to permit the flange of
each puller to lay flat on the face of the end
plate.
To avoid damaging the blower end plate,
be
sure
that
the
puller
retaining
capscrews are threaded all the way into
the tapped holes in the end plate to
provide maximum anchorage for the
pullers.
(17) Align the holes in each puller with the tapped holes in the end plate and secure the pullers to the end plate
with six 1/4 in. 20 x 1-1/4 in. capscrews.
(18) Turn the two puller screws uniformly clockwise and withdraw the end plate and bearings from the blower
housing and rotors.
