Where the pivot is:
- 5mm hex key with ball end
- 6mm hex key
- Rubber/plastic mallet
- Additional 5mm hex key or hex combination tool
- Two bolts
- Two countersunk washers
- Two brass bushings
- One threaded pin
1. Insert the ball end 5mm hex into the drive side (right) bolt.
2. Insert the second 5mm hex into the non-drive side (left) bolt.
3. While holding the drive side hex in place, loosen the non-drive side bolt by turning the hex key counter-clockwise. With the non-drive side loosened, the drive side bolt should be able to be loosened and removed with your fingers.
4. Thread the non-drive side bolt out and remove the countersunk washer. Thread the bolt back into the non-drive side.
5. While applying upward pressure on the pivot, gently tap the non-drive side bolt to push the center pin through.
6. Apply upward pressure on the pivot and remove the drive side brass bushing from the center pin.
7. Use the 6mm hex to gently tap the center pin towards the non-drive side, while taking care to not damage the threads.
8. While applying upward pressure on the pivot, remove the brass bushing from the non-drive side.
9. Thread the bolt into the non-drive side and while applying upward pressure on the pivot, gently tap on the 6mm hex with the mallet to push the center pin towards the non-drive side.
10. Gripping the bolt and the center pin while applying upward pressure on the pivot, the center pin can be pulled out.
11. This is how the pivot should look at this point.
1. Apply upward pressure on the pivot and begin tapping the new center pin into the pivot.
2. After tapping the center pin in, push the new brass bushing over the center pin.
3. Place the new countersunk washer on the non-drive side bolt and thread the bolt in a few turns. Then, gently tap the bolt towards the drive side.
4. While applying upward pressure on the pivot, press the new brass bushing onto the drive side of the center pin.
5. Place the new countersunk washer on the new bolt and begin threading the bolt into the drive side of the center pin.
6. Start tightening the non-drive side bolt with the 5mm hex key and the drive side bolt with the ball end 5mm hex key. The goal is to have each side threaded in the same amount. Once you are confident that both bolts are equal, tighten the bolts down to 28 Nm. Beware of over-tightening the bolts as the heads could strip; the Loctite on the threads will hold the bolts in.
7. Take the bike for a test ride and observe the bolts after the ride; further tighten the bolts if necessary.
