OK guys, I am getting paranoid. I have a 1997 variable 2HP and have removed and looked at the back gear housing. I think I have correctly determined that the gear set needs to be replaced, and am replacing the bearings on the small and large gears. I have received parts from Industrial Control and Automation, which has been mentioned by many posters as a good company to do business with. Their bull gear shaft bearings are about $30 apiece, though at various suppliers mentioned on this site they run from mid $20's to over $100 apiece. I talked with Wayne prior to ordering and he said they were good Japanese bearings they had used for the past 15 years or so with good success. These are marked "Japan EZO 6908 RS". I have since discovered numerous threads on this site that caution against using non angular or non preloaded bearings (regardless of ABEC number) because they have too much play axially and radially and so permit the bull gear shaft and bull gear to wander a bit. Since the gears cost over $250 I don't want to have to replace them again anytime soon because of improper alignment or wear. Posters have suggested using 7208 SU or DB? All I find are 7208 BB.... and they are over $200 apiece. Do I need to use different bearings thanwhat I bought? and if so, could someone give me a reference to a specific source and specific part number for angular and/or preloaded?? Thanks.
