skyway axles, how tight?
« on: February 27, 2013, 03:46 PM »
I am just putting my axles back into my skyways, I have never done this before. I have put the bearings in each side, put the metal cups on, how tight to I screw on the first nut*?

*not a nut but the circular bit of metal with the flats on the side

its a fine line - the wheel should spin free but have no sideways movement. Just keep adjusting it and then spin the wheel, you will get it right it may just take a couple of goes.  ;)

cheers Sid,

Sorted now but had a struggle, managed to play around and too slack I could feel movement, too right and the wheel was not spinning freely. As soon as I started tighetening the outer nuts on the forks, it was turning the inside axle nuts and putting pressure on the bearings and making the wheel tight. I got an angle grinder on an old spanner and halved the thickness of the spanner head making a thin spanner so I could stop the inner nuts moving, while tightening the outer ones. Sorted  :)

Cones should really just be finger tight and the bearings should run smoothly, then the hex locking nut gets tightened up against the cone nut  :daumenhoch:

Yup, cone spanners are thin steel spanners. Best ones are the really old bike spanner combos you could get on 70s/80s bikes. I used to feck no end up when I worked at Raynes. Another skiving method is lock one side up, fit wheel in frame or forks, tighten that side up on the frame and adjust. Sometimes a slight bit of play can't be picked up by spinning by hand.
