    Repairing an old Sturmey Archer 3 speed gear system

    Well, the little chain that comes out of the gear system has snapped.
    I think this is it - http://www.amazon.co.uk/Sturmey-Arch...ref=pd_cp_sg_0

    Now, I have no experience at all in fixing gear systems or anything similar. How difficult would it be for me to replace it with a new one?
    Also, how would it be done? Will I have to dismantle the whole system, or can it be simply be screwed in.
    Bike is an old Raleigh Stowaway, 3 speed.

    Cheers

    there are several lengths of the straight part of those indicator chains , which varies with the axle width .

    OVer there SJS cycles in the south, Bridgwater Somerset TA6 5HX is a well stocked S-A spare parts seller , here is the parts page

    Sturmey Archer Bicycle Equipment Shop at SJS Cycles


    the marks stamped in the shaft are indication of which one you need , ... yes it does unscrew ..

    I unscrew mine when I want to add oil to the gears inside.

    The Sturmey Archer HSA 125 is the right indicator spindle for a Stowaway, it fits the 146mm / 5 3/4 standard axle.

    If the chain has broken externally and is still exposed you should be able to unscrew it and replace it with the new spindle (it is a right hand thread).

    If it is broken off inside the hub you will have to learn how to dismantle the hub to access the spindle from the inside.

    You don't say what model hub you have, but the HSA125 indicator rod is probably the most commonly used. Replacing the rod is, as fietsbob suggests, simply a matter of unscrewing it from the axle key and screwing the replacement in. Don't force it; thread it in until it stops, then back it off enough to connect the cable. If you replaced it with the proper length rod, you adjust the gears by putting the shift lever in the "2" position and adjusting the cable tension using the barrel adjuster on the end of the cable. The cable is properly adjusted when the shoulder of the indicator rod is flush with the end of the axle when viewed through the windowed axle nut.
