A boiler feed pump (BFP) at a power plant was driven by a unique drive train experiencing elevated sleeve motor bearing temperatures and vibration. Testing methods included: Motion Magnification Video (MMV) testing, Experimental Modal Analysis (EMA) testing, Operating Deflection Shape (ODS) testing, and a vibration survey. Specific solution recommendations, including Finite Element Analysis (FEA) results and descriptive CAD drawings were presented. Subsequent post-fix testing confirmed the problem was resolved.
