• Hold with one hand the left-hand hand crank in the cor-
rect position, tighten manually the fastening screw (fig. 6)
until it the semiaxles engage, then apply a torque wrench
(to the 10mm hexagonal insert) and tighten to a 42 Nm ÷ 60
Nm torque (372 in.lbs ÷ 531 in.lbs) (fig. 6).
WARNING:
the titanium central screw FC-SR007 mounted
exclusively on Ultra-Torque Super Record crankset, with
titanium semiaxles, has a left-hand thread (to tighten,
turn anti-clockwise, to loosen, turn clockwise). Observe
the tightening direction that the arrow on the head of the
central screw shows (Fig. 6).
• Turn manually the screw until the two hand cranks, posi-
tioned in line, can no longer turn between them.
If the increased tooth is correctly positioned in the greater
slot on the opposite semiaxle, turning a hand crank with
respect to the other, the impact of the tooth can be clearly
noticed.Only at this point, apply a torque wrench (to the
10mm hexagonal insert) and tighten to a 42 Nm ÷ 60 Nm
torque (372 in.lbs ÷ 531 in.lbs) (fig. 7).
• Make sure that the hand cranks are correctly aligned.
DANGER!
Never use fixed Allen wrenches in place (Fig. 8) of a tor-
que wrench because, in addition to not being able to set
the correct tightening torque, they are often shorter than
65 mm, which may result in partial engagement on the
screw head with the possibility of damaging the screw
and generating cracks.
Screw breakage during use may lead to malfunction or
breakage, accidents, physical injuries or death.
