NOTE: Install the bearings dry when the clearance checks are made. Put clean engine oil on the main bearings for final assembly.

1. Clean the bearing surfaces in the cylinder block. Install the upper halves of the main bearings in the block.

2. Heat the crankshaft gear to a maximum temperature of 315°C (600°F). Install the gear on the crankshaft.Fasten a hoist to the crankshaft and put the crankshaft in position in the cylinder block with all timingmarks in alignment.

3. Clean the bearing surfaces of the main bearing caps. Install the lower halves of the main bearings in thecaps.

NOTE: When the bearing clearance is checked and the engine is in a vertical position, such as in thevehicle, the crankshaft will have to be lifted up and held against the upper halves of the main bearings to geta correct measurement with the Plastigage. The Plastigage will not hold the weight of the crankshaft andgive a correct indication. If the engine is in a horizontal position, it is not necessary to hold the crankshaft

up. Do not turn the crankshaft when the Plastigage is in position to check clearances.

NOTICE

Make sure the upper and lower halves of the main bearings areinstalled so the bearing tabs fit into the notch in the cylinder block andmain bearing caps.





4. Check the main bearing clearances with Plastigage (A) as follows:

a) Put a piece of Plastigage (A) in position as shown.

NOTE: Do not turn the crankshaft when Plastigage (A) is in position.

b) Install the main bearing caps. Put clean engine oil on the bolt threads and the face of the washersand install the bolts. Tighten the bolts to a torque of 30 ± 3 lb. ft. (40 ± 4 N·m).

c) Put a mark on each bolt and main bearing cap, then tighten the bolts 90° more.

d) Remove the main bearing caps. Remove Plastigage (A) and measure the width of the Plastigage.The main bearing clearance must be .0030 to .0065 in. (0.076 to 0.165 mm). The maximum

permissible clearance with used bearings is .010 in. (0.25 mm).

5. Put clean oil on thrust bearing (1) for the No. 7 main bearing. Install the thrust bearing with theidentification "BLOCK SIDE" toward the cylinder block.

NOTICE

Make sure the part number on the main bearing cap is toward thefront of the engine and the number on the main bearing cap is the

same as the number on the cylinder block on the left side of each mainbearing cap.

NOTICE

Do not use an impact wrench to tighten the bolts the additional 90°.





The tabs will not let the thrust bearing be installed backward.

6. Install the main bearing caps and tighten the bolts as in Steps 4b and 4c.

7. Check the crankshaft end play with tooling (B). The end play is controlled by the thrust bearings on the No. 7 main bearing. End play with new bearings is .0025 to .0145 in. (0.064 to 0.368 mm). The maximum permissible end play with used bearings is .025 in. (0.65 mm).

end by:

a) install pistons

b) install timing gear cover

c) install flywheel housing

d) install engine
