Feeling inspired by a modern replacement freewheel that is knocking after only 100 miles, I decided to try and tackle rebuilding this Suntour Perfect freewheel that was otherwise never going to get used. The 14t was a bit more stuck than I had hoped. On the first attempt the chainwhip slipped / bent and destroyed this poor 14t cog.



After straightening the chain whip in a vise, I was able to give it another go successfully.



And completely apart.



Am I wrong that these 14t cogs don't really come around too often? I'm wondering if this just needs to become a parts freewheel and I just need to obtain another. I looks like there are some "reasonably" priced 14-22 NOS ultra 6 freewheels available. Wondering if I could adapt these larger cogs with the narrower spacers onto this freehub. Or I guess I can always return the knocking freewheel to amazon and give a second one a try. Maybe I could even pull it apart and remedy the knocking with a clean and regrease.
