**TORQUE ALL BOLTS EVENLY
IN A CRISS--CROSS PATTERN
1 -- Torque bolts to 22 ft. lbs. (30 Nm)
2 -- Torque bolts to 51 ft. lbs. (70 Nm)
Leave at this torque for 1 minute to allow
gaskets to seat for proper sealing.
3 -- Loosen bolts evenly 360q (1 turn)
4 -- Torque bolts to 29 ft. lbs. (35 Nm)
5 -- From this point, tighten bolts
evenly 90q (1/4 turn)
6 -- Finally, tighten another 90q (1/4
turn)
7 -- Install two 6mm bolts and torque
to 6 ft. lbs. (8 Nm)
