I changed the 2 bearings on my mower deck spindle and am now putting everything back together. The mower is a Toro rear engine rider 10-32, Model 56190 circa 1992. The pulley sits on top of the upper bearing inner race and then a large nut screws on the spindle shaft on top of the pulley and holds everything tight.
The nut is rather large at 1 1/8", and when I disassembled I had to use a crescent wrench with a 2' long pipe over the wrench handle to break the nut loose. I didn't have a normal wrench that large. When I tighten the nut back up, does anyone know or have any ideas on how tight it should be? I don't want to put it on to loose but I am also worried about over-tightening since the pulley directly contacts the inner race of the bearing. Is there a point where you can tighten too much and put too much pressure on the bearing?
Also, I assume I need to put some grease on the shaft when I put everything back together. Would the Supertech general purpose grease at Wal-Mart work for that, or should I use something like white lithium or something else? Thanks for any help.
