CYLINDER BLOCK DISASSEMBLY (II)

Caution
• Placing the crankshaft on a disassembly bench will cause the drive gear to contact the disassembly bench because the crankshaft drive gear is larger than the counterweight. This could result in the drive gear being scratched or damaged which could become a source of noise. Therefore, set wood blocks or similar object on the both sides of the crankshaft or place a thick clean rag under the drive gear so that the drive gear does not contact the disassembly bench directly.
• The piston, piston pin and connecting rod (semi-floating type piston pin) cannot be disassembled.
• If the piston, piston pin, and connecting rod of the full floating type piston pin are disassembled, the piston, piston pin, and snap ring must be replaced as a single unit. Therefore, inspect the following items before disassembly so as to avoid unnecessary disassembly.
― Piston diameter (See PISTON INSPECTION.)
― Piston-to-cylinder clearance (See PISTON INSPECTION.)
― Piston and connecting rod oscillation torque (See PISTON AND CONNECTING ROD INSPECTION.)
― Connecting rod large end side clearance (See PISTON AND CONNECTING ROD INSPECTION.)

1.Disassemble in the order indicated in the table.

Pilot Bearing Disassembly Note

Note
• Only remove the pilot bearing if there is a malfunction in the pilot bearing or when replacing the crankshaft.

1.Use the SST to remove the pilot bearing.

Connecting Rod Cap Disassembly Note

1.Before removing connecting rod inspect the connecting rod side clearance. (See CONNECTING ROD INSPECTION.)

2.Remove the connecting rod bolt from the connecting rod cap by tapping the bolt with a plastic hammer.

Note
• The tappets are numbered to make sure they are assembled in their original positions. When removed, keep the tappets with the cylinder head they were removed from. Do not mix the tappets.

Main Bearing Cap Disassembly Note

1.Before removing main bearing cap inspect the crankshaft end play. (See CRANKSHAFT INSPECTION.)

2.Loosen the main bearing cap bolts in two or three steps in the order shown in the figure.
