Kia Sedona (2008 year). Instruction — part 364

5. Inspect cylinder bore diameter

Using a cylinder bore gauge, measure the cylinder bore diameter at position in the thrust and axial
directions.

Standard diameter

96.00-96.03 mm (3.7795-3.7807 in.)

1. Using a gasket scraper, remove the carbon from the piston top.

2. Using a groove cleaning tool or broken ring, clean the piston ring grooves.

3. Using solvent and a brush, thoroughly clean the piston.

2. The standard measurement of the piston outside diameter is taken 14 mm (0.5512 in.) from the bottom of

the piston.

Standard diameter

95.96-95.99 mm (3.7779- 3.7791 in.)

3. Calculate the difference between the cylinder bore diameter and the piston diameter.

Piston-to-cylinder clearance

0.03-0.05 mm (0.0012-0.0020 in.)

4. Inspect the piston ring side clearance.

Using a feeler gauge, measure the clearance between new piston ring and the wall of the ring groove.

Piston ring side clearance

Standard

NOTE:

Do not use a wire brush.

If the clearance is greater than maximum, replace the piston.

5. Inspect piston ring end gap.

To measure the piston ring end gap, insert a piston ring into the cylinder bore. Position the ring at right
angles to the cylinder wall by gently pressing it down with a piston. Measure the gap with a feeler gauge.
If the gap exceeds the service limit, replace the piston ring. If the gap is too large, recheck the cylinder
bore diameter against the wear limits. Refer to CYLINDER BORE INNER DIAMETER
REFERENCE. If the bore is over the service limit, the cylinder block must be replaced.
