Inspection
Cylinder block
Remove the sealing material.
Using a gasket scraper, remove all gasket material from the top surface of the cylinder block.
Clean the cylinder block.
Using a soft brush and solvent, thoroughly clean the cylinder block.
Inspect the top surface of the cylinder block for flatness.
Using a precision straightedge and feeler gauge, measure the cylinder head gasket contact surface for warpage.
Cylinder block gasket surface flatness
Standard: less than 0.05 mm (0.002 in.),
Less than 0.02 mm (0.0008 in.) / 100 x 100 (3.937 x 3.937 in.)

Inspect the cylinder bore.
Visually check the cylinder for vertical scratches.
If deep scratches are found, replace the cylinder block.
Check the cylinder bore diameter.
Using a cylinder gauge, measure the cylinder diameter at points in the axial and transverse directions.
Standard diameter: 72.00–72.03 mm (2.8346–2.8358 in.)

Installation
Remove the crankshaft.
(Refer to Cylinder Block - Crankshaft)
Remove the piston and connecting rod assembly.
(Refer to Cylinder Block - Piston and Connecting Rod)
Install the piston cooling oil jet (A).
Tightening torque: 8.8–12.7 N·m

Install the oil pan frame.
Using a gasket scraper, remove all old sealing material.
Install a new O-ring (A) on the cylinder block.

Before installing the ladder frame, apply TB1217H liquid sealant to the ladder frame.
Assemble the part within 5 minutes after the sealant has been applied.
Bead width: 2.5–3.5 mm (0.1–0.14 in.)

Install the ladder frame bolts and tighten them evenly in several passes.
Tightening torque: 28.4–32 N·m

Assemble the remaining components in the reverse order of removal.
