How to align multiple element drive trains. 2. How to align right angle drives. 3. The four general categories for measuring OL2R machinery movement hot and cold alignment 4. Calculating machine case thermal expansion 5. Inside micrometer-tooling ball-angle measurement methods 6. Proximity probes with water cooled stands technique 7. Using optical alignment tooling for OL2R machinery movement 8. Alignment bars with proximity probes OL2R method 9. Using laser-detector systems to measure OL2R machinery movement 10. Using the ball-rod-tubing connector system to measure OL2R machinery movement 11. Using the Vernier-Strobe system to measure OL2R machinery movement. 12. Mathematical- or graphical-modeling principles for all of the above methods 13. How to compensate for OL2R machinery movement when aligning rotating machinery Figure and Figure show sample problems that might appear on a Level 1 exam. Written or oral exams can test a person s knowledge on a subject but is somewhat inadequate in determining a persons skill level in performing specific tasks. Machinery alignment is a hands-on task. Someone can understand how the reverse indicator alignment method works but not be able to perform the method correctly. Perhaps the most effective means of verifying a person s knowledge and skill level is to have the person perform the task on a simulation machine or directly on an operating rotating equipment drive system at the plant site. However using process machinery as a test platform may not be possible. What if the equipment cannot be shut down for a scheduled test time or what if the person being tested misaligns the machine by mistake and no one checks to see that it is correct By having simulation equipment available testing can occur at virtually any time without impacting production or maintenance .
