The recommended procedures, practices, and checklists of API 686




API 686 provides detailed and comprehensive procedures, practices, and checklists for each topic related to machinery installation and installation design. These procedures, practices, and checklists are based on the best available knowledge and experience of the industry experts who contributed to API 686. They are intended to help ensure that the machinery is installed properly and safely, according to the manufacturer's specifications and industry standards.


For example, API 686 provides a procedure for aligning a pump and a motor using a dial indicator method. The procedure consists of several steps, such as:


  • Mounting the dial indicators on the coupling hubs or shafts.



  • Setting the dial indicators to zero at the top position.



  • Rotating both shafts together by 180 degrees and recording the dial indicator readings.



  • Calculating the vertical offset and angularity between the shafts.



  • Adjusting the shims under the motor feet to correct the vertical offset.



  • Repeating steps 2 to 5 until the vertical offset is within tolerance.



  • Rotating both shafts together by 90 degrees and recording the dial indicator readings.



  • Calculating the horizontal offset and angularity between the shafts.



  • Adjusting the motor horizontally to correct the horizontal offset.



  • Repeating steps 7 to 9 until the horizontal offset is within tolerance.



  • Checking the soft foot condition of the motor by loosening one foot at a time and measuring the change in dial indicator readings.



  • Correcting the soft foot condition by adding or removing shims under the motor feet.



  • Rechecking the alignment after correcting the soft foot condition.



API 686 also provides a checklist for verifying the alignment of a pump and a motor. The checklist consists of several items, such as:


  • The alignment method used is appropriate for the type and size of machinery.
