1. Record the main bearing code found on the front of the engine block.

2. Record the main bearing code found on the back of the crankshaft.

3. Using the data recorded earlier and the Bearing Select Fit Chart, Standard Bearings, determine the required bearing grade for each main bearing.

� Read the first letter of the engine block main bearing code and the first letter of the crankshaft main bearing code.

� Read down the column below the engine block main bearing code letter, and across the row next to the crankshaft main bearing code letter, until the two intersect. This is the required bearing grade for the number one crankshaft main bearing.

� As an example, if the engine block code letter is "F" and the crankshaft code letter is "D", the correct bearing grade for this main bearing is a "2".

� Repeat this process for the remaining four main bearings.

4. If oversize bearings are being used, use the procedure in the previous step and the Bearing Select Fit Chart, Oversize Bearings to determine the required bearing grade for each main bearing.

Position the lower bearing and connecting rod, and install the new bolts loosely.

17. NOTE: Main bearing caps are removed for clarity.

NOTE: Rotate the crankshaft after each connecting rod is installed and tightened to check for assembly binding.

Tighten the bolts in two stages, using the sequence shown.



� Stage 1: Tighten to 43 Nm (32 lb-ft).

� Stage 2: Tighten an additional 105 degrees.

18. Position the oil pump and install the bolts loosely. Tighten the bolts in the sequence shown.

19. CAUTION: The gasket sealing surfaces on the cylinder head and cylinder block must be clean. For additional information, refer to Cylinder Heads in the Removal portion of this section.

CAUTION: The use of sealing aids (aviation cement, copper spray, and glue) is not permitted. The gasket must be installed dry.

CAUTION: The new gasket has a film coating which is crucial to the gasket's ability to seal correctly. Do not scratch the gasket.

NOTE: The RH head gasket is shown; the LH head gasket is similar.

Install the head gasket over the dowel pins.

20. CAUTION: Cylinder head machining or milling is not authorized by the Ford Motor Company. Cylinder head flatness must be within 0.0254 mm (0.001 in) across a 38.1 mm (1.5 in) square area.

CAUTION: The gasket sealing surfaces on the cylinder head and cylinder block must be clean. For additional information, refer to Cylinder Heads in the Removal portion of this section.



CAUTION: The use of sealing aids (aviation cement, copper spray, and glue) is not permitted. The gasket must be installed dry.

CAUTION: Do not allow the dowels to scratch the sealing surface of the cylinder head during cylinder head installation.
