MISC: Chain Tensionposted by: Lee
on 2/6/2010 at 7:38:18 AM
How much crank chain tension should there be on a sturmey archer AW. If I tension as tight as a normal single speed there seems to a click noise while turning the crank. Almost like a bad spot on a chain would make but more than once per revolution. If i back it off enough to be quiet it seems it might be too loose and rubs against chain gaurd. by: 126.96.36.199

Grab the centre of the bottom of the chain and tug up and down. I like to have about an inch of play, tops. You should not be able to push the chain off the rear cog when turning the crank. The chainguard is flexible and adjustable enough to be made silent
A fixed gear would have half the slack depending on the uniformity of the crank. by: 188.8.131.52

That's about how much slack I have now. As far as the chain guard goes , I have a little adjustment but not much. It is on a Pashley that has a fully enclosed guard. I'll just have to tinker a tad. As far as the noise goes when the chain was taught is that typical. Probably putting too much pressure on pawls ? Thanks by: 184.108.40.206

Sorry I wasn't considering the enclosed chainguard...I've only ever owned one of them and it was fussy.
Check the axle to see if it's a little bent...this puts uneven pressure on the internals and can make noise. by: 220.127.116.11

The axles look good. If anything I might replace the chain. It seems like it might be a tad longer than needed. Back tire almost touching back inside of fender. Also excessive fender clearance on fender behind the seat tube. If the chain is shortened just a tad that might give me more clearance internally in the guard. Maybe.
