SERIAL NUMBER BELOW 310000000 SHOWN
NOTE: The rotor shaft and bearings can be serviced
without removing inner housing (item 23) from machine
(see Rotor Shaft in this section). For replacement of the
inner housing, stator vanes (item 10) or outer housing
(item 12), the following procedure is necessary.
NOTE: ProForce Blowers have used t hree (3) methods
of securing the inner and outer housings. On machines
with serial number below 310000000 (Fig. 13), the inner
housing is attached directly to the outer h ousing. On ma -
chines with serial number from 310000000 to
313000000, a fin spacer and possibly additional thin
spacers exist between the inner housing flanges and the
outer housing (Fig. 14). Machines with serial number
above 313000000 use four (4) fin mounts with fin
spacers and possibly additional thin spacers that are se-
cured b etween inner housing and outer housing (Fig.
15). Refer to correct illustration when removing and in -
stalling inner and outer housings.
