Re: Dismantling Suntour Perfect freehweel

Does anyone out there have experience taking these apart?
FWIW. The conventional wisdom is that you should NOT try to service a Freewheel ...
In other words, it would probably be 40x easier (i.e., if it takes you 1 hour to go to your bike shop & return home, allow at least 40 hours to try to service the Freewheel because you will probably spend a lot of time tryng to disassemble & reassemble it!) & less expensive ($20 for the Freewheel vs. a lot more for the tools) for you to get a new Freewheel from eBay OR even (!?!) your local bike shop.
FYI. SR bought out SunTour & subsequently renamed the combined product line SunRace ... but, the Freewheel removal tool is different for the SunRace Freewheels than for the SunTour Freewheels.
The current SunRace Freewheels are ramped & index compatible with 8-speed Shimano & Campagnolo shifters (if that ever becomes an issue). Use an 8-speed Shimano chain which is basically a copy of the Sedis Narrow
The 7-speed SunRace Freewheel will fit a 126mm spaced rear wheel.
Presumably, you need a 130mm spaced wheel for the 8-speed SunRace Freewheel.
If, for some reason, you can't get another 14-34 Freewheel exactly like the one you have, you can (of course) with some effort & special tools
remove the lockring + cogs & transplant the cogs to ANOTHER "SunTour Perfect" Freewheel body. I'm pretty sure the "SunTour Winner" body is slightly different, BTW, but maybe the difference was internal.
