Note: The top surface of the cylinder block for the gasket, the cylinder liners, and the bottom surface of the cylinder head for the gasket must be free of oil, fuel, water, and other contaminants before assembly.Note: Before assembly, lubricate the threads of the bolts and both sides of the washers with Loctite Graphite-50.Use the following procedure to tighten the cylinder head bolts:
Tighten bolt 1 through bolt 26 in a numerical sequence to 170 10 N m (125 7 lb ft).
Again tighten the bolt 1 through bolt 26 in a numerical sequence to 170 10 N m (125 7 lb ft).
Place a mark on bolt 1 through bolt 26. Rotate bolt 1 through bolt 26 in a numerical sequence to an extra 120 5 degrees (1/3 turn).
Loosen bolt 1 through bolt 26 to 0 N m (0 lb ft).
Tighten bolt 1 through bolt 26 in a numerical sequence to 170 10 N m (125 7 lb ft).
Again tighten the bolt 1 through bolt 26 in a numerical sequence to 170 10 N m (125 7 lb ft).
Place a mark on bolt 1 through bolt 26. Rotate bolt 1 through bolt 26 in a numerical sequence to an extra 120 5 degrees (1/3 turn).
Tighten bolt 27 through bolt 34 in a numerical sequence to 55 10 N m (41 7 lb ft).
