sudden mower deck noise

[peter lena 9,472]

my decks are very quiet, so when a rattling type of noise suddenly came up, i quickly dropped the deck and looked around, spindles were smooth and quiet . found the center spindle drive pulley to be a little loose , causing the rattling sound against the keyway , examination showed no damage to keyway or pulley. i had tightened everything up after rebuild ,re tightened with electric impact and 6 point impact socket . everything smooth and easy turning , added a couple of drops of  75x90 gear oil to the idler pulley bearing , when the bearing area bubbles up , its sucking in the lube. remounted deck and the quiet is back, staying after it , pete

I have had an issue with certain fasteners using an electric impact does not tighten it completely. Recheck by hand or torque wrench.
