the bolt.
2. To correctly install the cap, loosely install the bolts with
fingers.
3. Alternately, tighten the bolts in several steps to the specified
torque of 20
± 2 N⋅m (15 ± 1 ft-lb).
4. Make a paint mark on the head of each bolt.
CAUTION
• When the tightening angle is smaller than the specified
tightening angle, the appropriate tightening capacity
cannot be secured.
• When the tightening angle is larger than the specified
tightening angle, remove the bolt to start from the
beginning again according to the procedure.
5. Put another paint mark on the bolt head at 90 degrees in the
tightening direction from the first paint mark.
