Do not waste time on free, blurry scans labeled "new" that are actually 20 years old. Instead, invest in a legitimate digital copy from a technical bookstore or the publisher. The $50-$100 cost of the real document is a fraction of the cost of destroying one bearing due to a miscalculated balance using a corrupted PDF.
: Check for physical signs of wear, spalling, or lubrication loss, which will distort pure unbalance sinusoids.
Having the guide on a tablet or smartphone allows for immediate reference while standing next to a vibrating blower or motor.
Here is a breakdown of the core topics you will find inside:
A common question for new technicians is, "How much trial weight should I use?" Wowk provides empirical formulas for estimating a safe trial weight that is heavy enough to cause a measurable shift in vibration (usually a 30% change in amplitude or a 30-degree shift in phase), but light enough not to cause damage.
