1. Remove the piston rings and clean the grooves
and the piston rings.

2. Install new piston rings (2) in the piston grooves
(3).
3. Check the clearance for the piston ring by placing a
suitable feeler gauge (1) between piston groove (3)
and the top of piston ring (2) for the intermediate
ring and the oil control ring. Refer to Specifications,
"Piston and Rings" for the dimensions.
Inspect the Piston Ring End Gap

2. Place each piston ring (1) in the cylinder bore just
below the cylinder ring ridge (2).
3. Use a suitable feeler gauge (3) to measure piston
ring end gap. Refer to Specifications, "Piston and
Rings" for the dimensions.
Note: The coil spring must be removed from the oil
control ring before the gap of the oil control ring is
measured.

Connecting Rod - Inspect

If the crankshaft or the cylinder block are replaced,
the piston height for all cylinders must be measured.
Refer to Specifications, "Piston and Rings" for the
correct piston height.
Inspect the connecting rod for wear or for damage.
Refer to Specifications, "Connecting Rod" for the
correct dimensions.
Note: When the piston pin is installed, always install
g00905732
new retaining rings on each end of the piston pin.

Cylinder Block - Inspect

1. Clean all of the coolant passages and the oil
passages.
2. Check the cylinder block for cracks and damage.
3. The top deck of the cylinder block must not be
machined.
4. Check the front camshaft bearing for wear. Refer to
Specifications, "Camshaft Bearings" for the correct
specification of the camshaft bearing. If a new
bearing is needed, use a suitable adapter to press
the bearing out of the bore. Ensure that the oil hole
in the new bearing faces the front of the block. The
oil hole in the bearing must be aligned with the oil
hole in the cylinder block. The bearing must be
aligned with the face of the recess.

Cylinder Head - Inspect

1. Remove the cylinder head from the engine.
2. Remove the water temperature regulator housing.
