Hello Sold I have 2 of these 50-2481 newer blowers with the black hub. They need new bearings. If you can install the bearings this is a real bargain at $50 each plus shipping because new they are $326.00 !!! See post with pics on how to replace the bearings here GCI60, GC60, M55 Convection Fan Bearing See pics of Convection Blower below
