hey again guys- I just posted a moment ago but I didn't see it on the board, so i'll do a shorter one. don't know what happened. I have a 94 timberking b-16 with flat steel wheels. couldn't get it to track right, well, took a long time. took off the wheels and had them trued back flat again and replaced idle wheel bearings. they press in but seemed to be kinda loose. I got them plumb again and lifted up the guide rollers. this time they were fairly easy to set tracking on and I got it perfect when I turned wheels both ways. before, I would always lose my tracking adjustments when I changed blades and would have to spend couple of hours to do it again. this time took about 20 minutes. to check myself, I loosened blade 7 turns with my T handle, then tightened it back up 7 turns. spun the wheels and tracking was really bad. didn't stay. I think I have checked everything. drive side bearing wont move with a pry bar so I figure its good. all my bolts are good. the wheels stay plumb. someone mentioned loose bores on the bearings. the "pressed" fit did seem loose, like I could tap it lightly with small punch and it would come out of bore a little. can track it easy now but when I loosen tension and tighten it back, I lose everything. I have friends who say they set it one time on their mills and it stays. if I got it bored for a sleeve or something and then re-bored it for the bearing where it was tight, do ya'll think it would fix it? I don't think even belted wheels would solve it. would a loose fitting bearing do this? any help would be appreciated. thanks.
