Dismantle Freehub

Did this sometime back.

Freewheel or Freehub? See picture. Left is the traditional screw or thread-on Freewheel and the one on the right is the newer Freehub/Cassette configuration.

Typical Freehub

Hand itchy, this time tiak Freehub. I think this is the one Sultan last time said noisy. Anyway, after tiak liao machiam a ‘black box’, nothing much to play with. Just remove the rubber seal/washer, flush with degreaser and relube.

I use a 11mm hex wrench to loosen the freehub holding bolt. Sizes may differs. eg typical Shimano hub is 10mm, others may be 12mm etc

 

  Can see the steel balls after removing rubber seal.

Spin it in Diesel. Then shake it violently similar to cleaning chain :)

Spin & shake to remove as much trap degreaser as you can. (lazy to use dryer). Then inject lots of oil (I use Engine Oil) into the exposed bearings. Spin it and continue to inject oil until excess oil//trap degreaser flows from the underside.

Remember to grease both the pawls and holding bolt before assembly.
