                          Interpreting. we  see that the extension of  the motor shaft centerline
                           is 0.146 in. higher than the pump shaft  centerline at  plane "S" and.
                           the motor  shaft centerline is 0.220 in. higher than  the eXtenSiOI7  Of

                           Solving by plotting board we get the following; if the motor is moved:
