These parts have inspection items.

9. Baffle Plate - Remove


10. Connecting Rod Bearing Cap and Bearing Half - Remove

NOTE: Keep all connecting rod bearing caps and connecting rod bearings in order.

11. Lower Block - Remove
1.
Remove the 8 mm bolts in the sequence shown.
2.
Remove the bearing cap bolts. To prevent warpage, loosen the bolts in sequence 1/3 turn at a time; repeat the sequence until all bolts are loosened.
3.
Using a flat blade screwdriver, separate the lower block from the engine block in the places shown.
NOTE: Keep all the bearings in order.

2. CKP Pulse Plate - Install

NOTE: Apply new engine oil to the threads of the CKP pulse plate mounting bolts.

3. Crankshaft - Install
1.
Install the bearing halves in the engine block and the connecting rods.
2.
Apply a coat of new engine oil to the main bearings and the connecting rod bearings.
3.
Hold the crankshaft so rod journal No. 2 and rod journal No. 3 are straight up, then lower the crankshaft into the engine block.

4. Thrust Washer - Install
1.
Apply new engine oil to the thrust washer surfaces. Install the thrust washers (A) in the No. 4 journal of the engine block.

5. Lower Block - Install
1.
Apply liquid gasket to the engine block mating surface of the lower block, and to the inside edge of the threaded bolt holes.
2.
Put the lower block on the engine block.
3.
Apply new engine oil to the threads and flange of the bearing cap bolts.
4.
Torque the bearing cap bolts, in sequence, to 35 N·m (3.6 kgf·m, 26 lbf·ft).
5.
Tighten the bearing cap bolts an additional 41 °.
6.
Torque the 8 mm bolts, in sequence, to the specified torque.

7. Connecting Rod bearing Cap and Bearing Half - Install
1.
Measure the diameter of each connecting rod bolt at point A and point B.
2.
Calculate the difference in diameter between point A and point B.
Point A?Point B = Difference in Diameter
Difference in Diameter
Specification:
0?0.05 mm (0?0.0020 in)
3.
If the difference in diameter is out of specification, replace the connecting rod bolt.
4.
Apply new engine oil to the threads and flanges of connecting rod bolts (A).
5.
Seat the rod journals into connecting rod No. 1 and connecting rod No. 4. Line up the mark (B) on the connecting rod and the connecting rod bearing cap.
6.
Install the connecting rod bearing caps and the bolts finger-tight.
7.
Rotate the crankshaft clockwise, and seat the journals into connecting rod No. 2 and connecting rod No. 3. Line up the mark on the connecting rod and the connecting rod bearing cap.
8.
Install the connecting rod bearing caps and the bolts finger-tight.
9.
Tighten the connecting rod bolts to 5.0 N·m (0.51 kgf·m, 3.7 lbf·ft).
10.
Tighten the connecting rod bolts to the specified torque.
Specified Torque:
39 N·m (4.0 kgf·m, 29 lbf·ft)
11.
Tighten the connecting rod bolts an additional 120 °.
NOTE: Remove the connecting rod bolt if you tightened it beyond the specified angle, inspect the connecting rod bolts. Do not loosen it back to the specified angle.

8. Baffle Plate - Install


1. Crankshaft - Inspect

Out-of-Round and Taper
1.
Clean the crankshaft oil passages with pipe cleaners or a suitable brush.
2.
Check the keyway slot and the threaded holes.
3.
Measure the out-of-round at the middle of each rod and main journal in two places. The difference between measurements on each journal must not be more than the service limit.
Journal Out-of-Round
Standard (New):
0.004 mm (0.00016 in) max.
Service Limit:
0.010 mm (0.00039 in)
4.
Measure the taper at the edges of each rod and the main journal. The difference between measurements on each journal must not be more than the service limit.
Journal Taper
Standard (New):
0.005 mm (0.00020 in) max.
Service Limit:
0.010 mm (0.00039 in)




Straightness
5.
Place the V-blocks on a flat surface.
6.
Check the total runout with the crankshaft supported on V-blocks.
7.
Measure the runout on all of the main journals. Rotate the crankshaft two complete revolutions. The difference between measurements on each journal must not be more than the service limit.
Crankshaft Total Runout
Standard (New):
0.03 mm (0.0012 in) max.
Service Limit:
0.03 mm (0.0012 in)
