Suntour Freewheel Freewheel bearing sizes needed for Suntour?
It fell apart on the road, I am seeking the two bearing sizes and approximate quantity please.
I'm going on the assumption that this is indeed a freewheel, not the modern freehub made popular by Shimano. If it is the latter, see the 1st link below for more.
Most freewheel bearings are 1/8". They can be gotten at any good bike shop. Roughly low 30's and 40 for each set respectively. They'll probably be around $2-5 for the set depending on the shop for about 100-150. The trick to holding the bearing in place is to use a bead of grease and gravity to hold them while you assemble. See 2nd link for more.
The other option is to simply change the freewheel or freehub. Older 5 speed freewheels are roughly $15! A freehub body is roughly $25-75 depending on which model and how old.
I'm converting this for touring use. I presume that this is a lower end bike, not worth much (is to me!)
How tough is this frame/fork? I do some backwoods camping, but no silly-sick off road use.
I checked into this link

And the component dates match the 1983 suggestion from mirage....Some folks are suggesting that Ishiwata is the mfr of the tubing (rather than Tange?) But with late '82 components I think you're quite right about the 1983 model year. $15 for the bike & components...a little for tires & tubes & we've got at least a thousand miles down the road. Great Bike!! Thanks
Actually, it isn't a horrible bike... probably at or near Fujis top of the line in , um, 1983. Thinking about it, only the Fuji Newest was above the Supreme. The Supreme is still made but it has been morphed into a lower end hybrid bike.
The frame and fork is Tange 4130 Chrome Molybdneum with Fujis brand on it. Great stuff.
If you are REALLY going to tour with it and are planning to update the parts remember that the rear wheel spacing is narrower than modern 7, 8, 9, or 10 speed rears and the frame will have to be reset by someone that knows what they are doing... you can't just "spring" the rear wheel in place.
Good luck!
EDIT: I am sticking with Tange. Although Ishiwata was a material that they used it was for their lower end CrMo frames. You could lok for a stamp under the top tube of the frame near either end to confirm, but it may be filled with paint. Either way, the tubing will be well suited for your needs.
Fourples were semi-common when the littlest chainring you could get was a 24t, some guys made a gadget that let you put a Suntour freewheel cog as little as 19t on the crank as a 4th ring.
The very first Avid product was a 20t chainring and adapter to fit 74mm triples…
In 1984 there were cool Cannondale aluminum mtn bikes for the first time and some of my annoying friends made one-speeds out of them with Campy Record derailleurs serving as tensioners-the bikes had vertical drop-outs….
It didn't take long for someone to figger out that you could use a triple or fourple crank with a front derailleur and a one-speed freewheel to make…..Voila! The Vacaville ThreeSpeed!
Yo, BikeFag!
