Xylem 8100 Series Centrifugal Pumps AC2515 REV.C - Manual (Page 10)

straddling the support arm, and install
but do not tighten the two remaining
capscrews.
ii. For pumps without a motor saddle
support bracket: Insert the spacer
washer between the holes located
closest to the motor in the outer guard,
and install, but do not tighten, the two
remaining capscrews.
f. Position the outer guard so it is centered
around the shaft, and so there is less than
a 1/4" of the motor shaft exposed. On
guards that utilize a slotted support
bracket, the inner guard will have to be
positioned so there is only a 1/4" of the
pump shaft exposed.
g. Holding the guard in this position, tighten
the three capscrews.

Method 1 – Straight Edge Alignment for
Standard Sleeve Type Coupler with Black
Rubber Insert
(See Figure 10A)
Proceed with this method only if satisfied that
face and outside diameters of the coupling
halves are square and concentric with the
coupling borers. If this condition does not
exist or elastomeric couplings do not make
this method convenient, use Method 2.
1. Check angular misalignment using a
micrometer or caliper. Measure from the
outside of one flange to the outside of the
opposite flange at four points 90° apart.
DO NOT ROTATE COUPLER.
Misalignment up to 1/64" per inch of
coupler radius is permissible.
2. At four points 90° apart (DO NOT
ROTATE COUPLER), measure the
parallel coupler misalignment by laying a
straight edge across one coupler half and
measuring the gap between the straight
edge and opposite coupler half. Up to a
1/64" gap is permissible.
