    HELP: How to service Cannondale Expert Hub Freewheel

    My freewheel is in need of service. I am not sure whether just a cleanup / grease cycle will be sufficient or whether it will need to be replaced, but right now I am trying to figure how to take it apart...

    It's a 2001 vintage Cannondale expert hub.

    My Cannondale LBS service manager said that I could just knock the free wheel off by taping the axle from the non-drive side. I tried gently taping and the drive side bearing came out. The axle is still captive.

    I am rather concerned about starting to whack pretty hard on the aluminum axle to try to push out the freewheel assembly. When I look at it (see pictures), it looks like there are two indentations inside the freewheel which might be used to "unscrew" the freewheel with a special tool.

    Wisdom of the MTBR Cannondale specialists is welcome.

    Thanks.

    DRC

    Got help from my local LBS (thanks Rob at Mike's Bike in Palo Alto, CA)

    OK,

    Since I didn't get that many answers from the mtbr lurkers (not hot wrenches in here), I went and bug my LBS.

    The trick is to tap the axle from both sides to extract both bearing, then going from the non drive size with a 12 mm Allen wrench to unscrew the freewheel assembly.

    Trouble is that (according to the service guy) they come assembled from the factory with loctite and tightened with a impact wrench.

    So... I know how to take it apart, but couldn't in mine (didn't want to use too much force and risk tearing the spokes off the rim!)

    Thanks again to Rob at Mike's Bike in Palo Alto (BTW, Mike's Bike is one of the largest Cannondale dealer in the US).
