One mine was the one-way bearing pressed in upside down, bearing blocks the wrong way.

Upgraded bearing stand SJM500
Oct 04, 2008
This upgraded bearing stand comes with 2 one-way bearings installed in stead of only 1 in the old. Much better then the original, which is likely to fail if you pump the pitch a lot. (it failed twice on mine, forcing an autorotation)
