The following bolts are 216 mm (8.5 inch) long: 11, 12, 13, 14, 16, 18, 20, 22, 24 and 26. The following bolts are 198.8 1.0 mm (7.83 0.04 inch) long: 2, 8 and 10. The rest of the bolts are 194 mm (7.6 inch) long.Apply 6V-4876 Lubricant to the bolt threads and both sides of the washers. Tighten the bolts in the following step sequence:
In a numerical sequence, tighten bolts 1 through 26. Torque for bolts ... 270 15 N m (200 11 lb ft)
In a numerical sequence, tighten bolts 1 through 26. Torque for bolts ... 450 15 N m (330 11 lb ft)
In a numerical sequence, again tighten bolts 1 through 26. Torque for bolts ... 450 15 N m (330 11 lb ft)Note: The flatness of the cylinder head should be within a total of 0.13 mm (0.005 inch). Also, the flatness of the cylinder head should be within a maximum of 0.05 mm (0.002 inch) for any 150 mm (5.9 inch) span.
