Thanks again bertsmobile1. Tried your last suggestion of 6/29. Thought working when discovered blade bolt was just loosening. Tried several other methods with tools/equipment I had to hold spindle shaft in place without success. Found & purchased a GM spanner wrench that fit holes in top mounted pulley. With 2 cheater bars & lots of PB blaster finally broke loose. I had to use same spanner wrench with 3 jaw 7" diameter puller, 2 cheater bars, more PB blaster & lots of torque to remove the top pulley. Discovered bottom pulley key had slide out of shaft slot wearing down spindle shaft. So, after attempt to remove bottom pulley in same manner--had to drill out the slipped key with 1/4" bit to remove. Both pulleys were bent in process of removal. Spindle shaft & bottom pulley were damaged beyond reuse before removal. (Had planned to reuse all if in ok shape). The problem originally trying to repair (loose spindle to deck bolts)--found bolts stripped--so should be easier repair with bit longer bolts thru spindle housing base & deck locked down with nuts. Believe the cause of bolts stripping was the slipped key from the spindle shaft slot causing out of center spin/balance/rotation of bottom pulley & shaft wear. Who knows. Amazing to me how well this mower was mowing until 3 of the deck bolts stripped. Now to find replacement spindle assembly, housing & pulleys. And, reference seizing--I am a firm believer in using anti-seize compound when replacing parts. Thanks again!
