COMPONENT NOTES
Connecting Rod (3)
- Only replace as a set.
- Mark cylinder number on rod -A-.
- Installation position:
- Marking -B- faces toward pulley end.
- When replacing rods, piston protrusion must be measured and the correct head gasket selected, refer to Cylinder Head Gasket.

Connecting Rod Bearing Cap (4)
- Note installation position.

Connecting Rod Nuts (5)
- Tighten in two stages:

- First stage, tighten to: 30 Nm (22 ft. lbs.)
- Second stage, turn: an additional 90° (1/4 turn).

- Oil threads and contact surfaces.
- Tighten only to: 30 Nm (22 ft. lbs.) when measuring radial (oil) clearance.

Bearing Shell (8)
- Note installed position
- Do not interchange used bearing shells
- Ensure that retaining lugs fit tightly in recesses
- Axial clearance:

- New: 0.5-0.31 mm (0.0020-0.0122 inch).
- Wear limit: 0.37 mm (0.0146 inch).

- Check radial clearance with Plastigage:

- New: 0.01-0.06 mm (0.0004-0.0024 inch).
- Wear limit: 0.12 mm (0.0047 inch).

- Do not rotate crankshaft when checking radial clearance.
