Tightening needed
Preliminary
tightening torque,
Nm (kgf m)
Tightening is performed in three
steps:
1. Preliminary tighten (2–3
revolutions)
2. Start
in
successively moving toward
both sides, tighten to torque of
20–30 Nm (2.0–3.0 kgf·m).
3. Starting from the left end,
successively move to right and
tighten additionally to torque
73.54 ± 4.9 (7.4 ± 0.5)
50 – 55 (5.0 – 5.5)
195 ± 5 (19.5 ± 0.5)
50 – 55 (5.0 – 5.5)
45 ± 2 (4.5 ± 0.2)
16 ± 1 (1.6 ± 0.1)
5 (0.5)
25 + 8 (2.5 + 0.8)
Tighten to maximum torque
in case of fuel leakage
22 – 25 (2.2 – 2.5)
8 – 10 (0.8 – 1.0)
8 – 10 (0.8 – 1.0)
Final tightening
to angle in
degrees or torque
in Nm (kgf m)
