SPECIFICA TIONS
For general locking torque (except appointed locking
torque), locking torque force is determined by thread
diameter (two-face width) and thread pitch when fas-
tening a screw and a screw cap.
Tightening order of steering system (dual
toroidal nut)
1. First, the nut (serial number ) is fastened to
30
35N.m.
2. Then, the direction handle is turned from left to
right 2
3 times. Clamping stagnation must not be
occurred and the ball race is not flexible while the
direction handle is turned.
3. After that, the nut (serial number
) is unscrewed
one-quarter turn, and then fastened. Its fastening
torque is 20
24 N.m.
4. The nut (serial number
) is turned to press against
the nut (serial number
).
5. Then a special gasket of the nut (serial number
)
is assembled, a retaining pawl should be jammed in
the furrows of the nuts (serial number
and ) in
the meantime. If the furrows are not aligned, the nut
(serial number
) should be turned to guarantee
alignment.
Tightening order of steering system (securing
nut with dustproof)
1. First, the nut (serial number ) is fastened to
30
35N.m.
2. Then, the direction handle is turned from left to
right 2
3 times. Clamping stagnation must not be
occurred and the ball race is not flexible while the
direction handle is turned.
3. After that, the nut is unscrewed one-quarter turn,
and then fastened. Its fastening torque is 20
24 N.
