Item  Qty  Part  Specification Description 
Before installation of the flywheel housing, inspect the following components for any foreign materials: The front face of the flywheel housing, the two sides of the flywheel housing gasket and the rear face of the cylinder block. These components must be free of the following substances: oil, fuel, water, gasket adhesive, assembly compounds, and any other foreign material. Apply ultra blue Loctite 587 to seal the joints between the engine oil pan, cylinder block, and the flywheel housing. 
223-4903 Bolt  Use the following procedure to tighten the flywheel housing bolts:

1.Tighten bolt 1 through bolt 9 in the numerical sequence as shown in Illustration 1 to 100 ± 20 N·m (75 ± 15 lb ft) in the numerical sequence.
2. Tighten bolt 10 through bolt 23 in the numerical sequence as shown in Illustration 1 to 40 ± 10 N·m (30 ± 7 lb ft) in the numerical sequence.
3. Again, tighten bolt 1 through bolt 9 in the numerical sequence as shown in Illustration 1 to 135 ± 20 N·m (100 ± 15 lb ft) in the numerical sequence.
4. Again, tighten bolt 10 through bolt 23 in the numerical sequence as shown in Illustration 1 to 55 ± 10 N·m (41 ± 7 lb ft) in the numerical sequence.
