Tightening sequence

Tighten the bolts that hold the flywheel housing to the cylinder block in the sequence that follows:

1. In a numerical sequence, tighten bolt ( 1) through bolt (17) .

   Torque for bolts ... 40 ± 10 N·m (30 ± 7 lb ft)

2. In a numerical sequence, again tighten bolt (1) through bolt (8) .

   Torque for bolts ... 135 ± 20 N·m (100 ± 15 lb ft)

3. In a numerical sequence, again tighten bolt (9) through bolt (17) .

   Torque for bolts ... 55 ± 10 N·m (41 ± 7 lb ft)

4. Tighten plug (18) .

   Torque for plug ... 55 ± 14 N·m (41 ± 10 lb ft)
