4) If installing the sprockets without the plastic support,
install the individual or preassembled sprockets and the
spacers on the sprocket body of the hub aligning the spline
patterns (Fig. 27). The profile of the freewheel body with two
asymmetrical grooves (Fig. 27) ensures automatic sprocket
timing since there is only one assembly option.
5) Using a torque wrench (D - Fig. 28) together with the
Campagnolo tool UT-BB080 (B - Fig. 28), tighten the ring
®
nut (G - Fig. 28) that came with the Campagnolo
pack onto the freewheel body, observing the tightening torque
indicated on the instruction sheet of the sprocket pack.
5.2.2 - DISASSEMBLY
1) Remove the lockring (G - Fig. 29) using the Campagnolo
tool UT-BB080 (B - Fig. 29) with a 24 mm hexagonal wrench
(E - Fig. 29) and the chain whip Campagnolo
(F - Fig. 29).
2) Insert the plastic sprocket carrier on the side of the
freewheel body and align the spline patterns on the body
with those on the carrier. Slide the sprockets onto the carrier.
3) Slide the sprockets, off the freewheel body (Fig. 30).
