I have a few questions for the experienced mechanics. I just replaced the outer spindle bearing in my 60" toro. After a few hours of use things loosened up again. Wondering what may be wrong? Heres how the install went, Starting from top to bottom. Seal, spacer, a snap clip of some sort (to hold the bearing in), bearing/race, center spacer, small clip, bearing/race (bottom), spacer, seal. The larger snap clip was installed on the upper bearing, the small clip which looks like it would snap into place but doesnt, was installed on the lower between the large middle spacer and the bearing/race. It looks like the small snap clip helps keep the middle spacer from moving around? I think I have the clips upside down or something as things have loosened up already. Please give me some insight.
