          Indicator clamps for bridging across the coupling sleeves and/or hubs
        should be  installed as shown in Figure 6-3 1. This method  allows the final
        hot alignment check to be made without disconnecting the coupling halves.
        Since no two couplings can be aligned absolutely perfectly, suggested maxi-
        mum  allowable runout values for use in alignment procedures are listed in
        Table 6-1. Proceed with the hot alignment check in the following manner:


          1.  Record  ambient  temperature  and oil  sump temperature  on  work-
            sheet.
         2.  Rotate shafts in the direction they were designed to operate under
            load conditions.
