Introduzione

Vai al passo 1

This is a guide to removing and replacing the bottom bracket on the Windsor Willow. The bottom bracket is a self-contained bearing surface on which the crank arms and drive gears rotate. Note that the rear wheel is missing in the photos, but does not necessarily need to be removed for this guide.

    • To separate the Master Link, hold the left side of the link in your left hand and the link to the right in your right hand. Push the two links together to enable the release. Pull the links apart, one hand moving towards yourself and the other away from you. This will separate the links of the chain.

    • To remove the crank arm, place a proper fitting Allen wrench into the slot at the center of the crank arm as shown. Turn the wrench counterclockwise to loosen the bolt that keeps the crank arm on the bike until it spins easily. Hold the other crank arm in place to ensure that the bolt loosens instead of spinning the crank arm.

    • Obtain a crank puller tool. This tool has two parts, a movable threaded insert and the push bolt. Screw the crank puller into the hole left by the bolt.

  18. Windsor Willow Bottom Bracket Replacement: passo 17, immagine 1 di 2 Windsor Willow Bottom Bracket Replacement: passo 17, immagine 2 di 2

Conclusione

To reassemble your device, follow these instructions in reverse order, keeping in mind that the drive-side threads are reverse threads, meaning counterclockwise turning tightens the piece and clockwise turning loosens the piece.
