[QUOTE="skidsteer.ca, post: 4415, member: 307"] I got my new hub finally and it came complete with the seal and the bushing for $83 cdn. I welded the seal surface up with the mig and the casting has good steel in it and it welded perfectly. Bolted it up to my lathe and turned it back down, good as new. The seal only slides on this sureface when the excentric rotates to “adjust “ the belt. So it does not have to be “110%” so to speak. Re asembly went good and the spring is a piece of cake, nothing nearly as ignorant as the rewind springs, you only have to wind it a 1/3 of a turn. The new 6207 bearing was available from my local bearing supplier for $16. Bearing is held to the hub with a internal and external snap ring so you need some pliers to remove these. I'll post another pic of the back of the asembly, as you can check how much the bushing is worn by looking at how close the pin is to side of the “curved slot“ in the back of the tightener. This check only requires you remove it from the machine not tear it apart. I'll be checking mine at 250 hours now, until i see how the grease is lasting. Probably it would be good for 1000 or so.
