NOTICE:

When installing the upper side rail and lower side rail, the ends of the oil ring expander may overlap. If it occurs, the upper side rail or lower side rail may move out of its groove.

(3) Check that the ends of the oil ring expander are not overlapping and that the upper side rail and lower side rail are securely installed into the groove.

NOTICE:

• After installing the oil ring expander, upper side rail and lower side rail, press around the circumference with a finger to check that they are securely installed into the groove.
• If the oil ring expander is not securely installed into the groove, check that the ends of the oil ring expander are not overlapping.
• If the ends of the oil ring expander are overlapping, remove the upper side rail and lower side rail and realign the oil ring expander using a screwdriver.

7. INSTALL CRANKSHAFT BEARING

(1) Clean the main journal and both surfaces of the No. 1 crankshaft bearings and No. 2 crankshaft bearings.

(2) Install the 5 No. 1 crankshaft bearings to the cylinder block sub-assembly as shown in the illustration.

NOTICE:

Do not apply engine oil to the No. 1 crankshaft bearings or the contact surfaces.

HINT:

Both sides of the oil groove in the cylinder block sub-assembly should be visible through the oil feed holes in the No. 1 crankshaft bearing. The amount visible on each side of the holes should be equal.

(3) Install the 5 No. 2 crankshaft bearings to the 5 crankshaft bearing caps.

NOTICE:

Do not apply engine oil to the No. 2 crankshaft bearings or the contact surfaces.

(4) Using a vernier caliper, measure the distance between the crankshaft bearing cap edge and No. 2 crankshaft bearing edge.

Difference between (A) and (B):

0 to 0.7 mm (0 to 0.0276 in.)

8. INSTALL CRANKSHAFT THRUST WASHER

(1) Install the 2 crankshaft thrust washers to the No. 3 journal position of the cylinder block sub-assembly with the oil grooves facing outward.

(2) Apply engine oil to the crankshaft thrust washers.

9. INSTALL CRANKSHAFT

(1) Apply engine oil to the upper crankshaft bearings and install the crankshaft to the cylinder block sub-assembly.

10. INSTALL CRANKSHAFT BEARING CAP

(1) Apply engine oil to the lower crankshaft bearings.

(2) Confirm the front marks and numbers, and place the 5 crankshaft bearing caps on the cylinder block sub-assembly.

(3) Apply a light coat of engine oil to the threads and under the heads of the crankshaft bearing cap set bolts.

(4) Using a plastic hammer, lightly tap the crankshaft bearing caps to ensure a proper fit.

(5) Install the crankshaft bearing cap set bolts.

NOTICE:

The crankshaft bearing cap set bolts are tightened in 2 progressive steps.

(6) Uniformly tighten the 10 crankshaft bearing cap set bolts.
