    What tools for BB/Crankset removal/repair???

    I have a 1999 Specialize Hardrock Comp FS A1 that has a square taper BB

    I am looking to replace the crankset and Bottom Bracket and thinking something like this:

    What tools are needed for this removal and replacement?

    Any suggestions on where to buy cheap tools.

    Thanks

    To remove the square taper crankset and bottom bracket, you will need:

    1. a long 8mm Allen key (for the crank bolts).
    2. a TL-FC10 Crank Extractor or compatible tool to remove the cranks.
    3. a TL-UN74-S or compatible tool to remove the lockring and BB.
    4. a big adjustable spanner

    If the TL-UN74-S tool slips then just improvise a tool (from an M8 bolt and a large diameter washer) to hold it securely in place.

    To install the Shimano Hollowtech II BB cups and crankset:

    5. a TL-FC32 spanner to screw in the outboard BB bearing cups.
    6. a TL-FC16 for the preload screw.
    7. a 6mm Allen key for the left crank pinch bolts.

    I have listed the original Shimano service tools required, but I would recommend that you buy the compatible versions of them instead because they often include extras for the same price. For example, the compatible version of (2) often also includes a small adapter cap for removal of ISIS and Octalink cranks. The compatible version of (5) often combines (5) and (6) on a single tool.

    Look for tools that have been chemically treated a black colour as they are more robust than their plated or untreated counterparts.
