8 - Place  the  electric  motor  on  the  baseplate  and  bring  the  two  coupling  halves  together  with  approx.  2  mm  gap 

between them keeping the motor axially aligned with the pump shaft.  In  the  event  the  two  shaft  heights  do  not 
align,  proper shimming under the pump or motor feet will be required. Mark the motor and/or pump anchoring bolt 
holes. Remove motor and/or pump, drill and tap the holes, clean and mount pump and/or motor in place and lightly 
tighten the bolts (see fig. 24).

9 - With  a  straight  edge  ruler  check  the  parallelism  of  the  two  coupling  halves  at  several  points  ,90°  from  each  other 

(see fig. 26). 

NOTE: 

Easier  and  more  accurate  readings  can  be  attained  with  instruments  such  as  Dial  Indicators  (if  readily 
available).

If the maximum value of "X" is higher than that listed in the tab.  6 (for the given coupling size) it will be required to 
correct the alignment by using shims under the pump or motor feet. 
When the measured values fall within the tolerances, the pump and motor mounting bolts can be tightened. 

 
10 -  Angular misalignment can be measured with a caliper. Measure the outside coupling dimension at several points 

(see fig. 27).
