disc assembly on to the compressor shaft. Shaft
should be recessed 3/8” (9.5mm) from the face of
the hub. Gradually tighten all shrink disc locking
screws to 42 ft.---lbs. (57 Nm) (see Installation of
Shrink Disc and Figure 6---6).
STEP 2 --- CHECK ALIGNMENT
Angular --- Take readings with an inside microme-
ter at 90
_
intervals between flange faces. If a dial in-
dicator is used, compensate for sag and attach it
on one shaft and rotate the hub 360
_
while taking
readings on the flange face as shown.
DO NOT ex-
c eed instal l a tion A N GU LA R l imit spec if ied in
. When using a dial indic a tor, the best r esul ts ar e
achieved by rotating both driver and driven shafts
together.
CAUTION
!
Dial indicator face readings should not be used
on journal bearing equipment due to the liberal
end float inherent in such a design.
