(Part 2 Of 2):

1. Install, but do not tighten, lower cylinder block to upper cylinder block retaining bolts.
2. Tighten lower cylinder block to upper cylinder block bolts in sequence shown at this time to 3-5 Nm (27-44 inch lbs.).
3. Push crankshaft rearward and then lightly, using a prybar or a similar tool, seat crankshaft thrust washer forward.
4. Tighten lower cylinder block to upper cylinder block retaining bolts in sequence, as follows:
- Tighten fasteners 1 through 8 to 22-28 Nm (17-20 ft. lbs.).
- Tighten fasteners 9 through 16 to 37-43 Nm (28-31 ft. lbs.).
- Rotate fasteners 1 through 16 an additional 85-95°.
- Tighten fasteners 17 through 22 to 20-30 Nm (15-22 ft. lbs.).
5. Verify crankshaft rotates freely and does not bind. Clean any residual sealer from inside the cylinder block with a clean shop towel.
