Method 2 – For Orange Hytrel Insert, 3500 RPM Operation, or All Other Coupler Types
(See Figure 7B)
a.Make sure each hub is secured to its respective shaft and that all connecting and/or spacing elements are removed at this time.
b.The gap between the coupling hubs is set by the manufacturer before the units are shipped. However, this dimension should be checked. (Refer to the coupling manufacturer’s specifications supplied with the unit.)
c.Scribe index lines on coupling halves as shown in Figure 7B.
d.Mount dial indicator on one hub as shown for parallel alignment. Set dial to zero.
e.Turn both coupling halves so that index lines remain matched. Observe dial reading to see whether driver needs adjustment (See paragraph i below).
f.Mount dial indicator on one hub as shown for angular alignment. Set dial to zero.
g.Turn both coupling halves so that index lines remain matched. Observe dial reading to see whether driver needs adjustment (See paragraph i below).
h.Assemble coupling. Tighten all bolts and set screw(s). It may be necessary to repeat steps c through f for a final check.
i.For single element couplings, a satisfactory parallel misalignment is
.004"T.I.R., while a satisfactory angular misalignment is .004"T.I.R. per inch of radius R (See Figure 7B).

Final Alignment
Final alignment cannot be accomplished until the pump has been operated initially for a sufficient length of time to attain operating temperature. When normal operating temperature has been attained, secure the pump to
WARNING: Rotating Components
Hazard
Do not operate pump without all guards in place. Failure to follow these instructions could result in serious personal injury or death and property damage.
OPTIONAL Alignment Procedure
If desired, the pump and motor feet can be doweled to the base after final alignment is complete. This should not be done until the unit has been run for a sufficient length of time and alignment is within the tolerance. See Doweling Section.
CAUTION: Extreme Temperature and/or Flying Debris Hazard
Eye protection and gloves required. Failure to follow these instructions could result in property damage and/or moderate personal injury.
NOTE: Pump may have been doweled to base at factory.
DOWELING
Dowel the pump and driving unit as follows:
a.Drill holes through diagonally opposite feet and into the base. Holes must be of a diameter 1/64 inch less than the diameter of the dowel pins. Clean out the chips.
b.Ream the holes in feet and base to the proper diameter for the pins (light push fit). Clean out the chips.
c.Insert pins to be approximately flush with feet.
SUCTION AND DISCHARGE PIPING
General
When installing the pump piping, be sure to observe the following precautions:
Piping should always be run to the pump.
Do not move pump to pipe. This could make final alignment impossible.
Both the suction and discharge piping should be supported independently near the pump
