Three-speed hub tightness
I got a tight three-speed hub. The shifting is just fine, but when the bike is on the stand and I get the wheel spinning, it spins the crank along with it. Even worse, when I spin the crank backwards, the wheel will very slowly begin to spin backwards as well. It is NOT one of those nifty three-speed fixed gear hubs.
What's worse, the tightness seems to be concentrated into about 15 degrees out of the 360 that the hub makes around the axle. Do you think that maybe the sun pinion is missing some teeth?
I tried adjusting the left-side cone, to no avail.
The chain is not too tight.
The hub is a Hercules B-Type (pre SA acquisition)
I DO NOT want to take the hub apart, unless absolutely neccesary. If I do have to take it apart, do I need any special tools?
Thanks for any advice
