Question. I have a 1990 single stage snow thrower for my 312-8. I am trying to replace the bearings on the drive shaft. How do you remove them? I have taken out the set screw, soaked the collar in pb blaster, put some heat to them, pounded on them. etc. They will not move. Am I missing something? The only thing that is curious is, there is only one set screw in each bearing collar. There appears to be a second partially drilled hole but no set screw installed and it does not appear to be tapped. What gives???
