Kia Carens. Manual — part 44

7. Replace a feeler gauge in end gap and check end gap clearance.

End gap clearance

Ring

Specification

Top ring

0.006~0.011in (0.15~0.30mm)

Second ring

0.012~0.018in (0.30~0.45mm)

Oil rail

0.008~0.027in (0.20~0.70mm)

Maximum

0.039in (1.0mm)

8. Replace piston ring if necessary.

Piston pin

1. Measure each piston pin hole diameter at X and Y directions in four locations shown in figure.

Diameter : 0.7872~0.7875in (19.994~20.002mm)

2. Measure each pinston pin diameter at X and Y direction at four locations shown.

Diameter : 0.7869~0.7871in (19.987~19.993mm)

3. Subtract piston pin diameter from pin hole diameter to determine piston to piston clearance.

Clearance : 0.00004~0.0006in (0.001~0.015mm)

4. If clearance exceeds specification, replace piston and pinston pin.

Piston and piston pin are a matched set.

INSPECTION

1. Check connecting rod bushing inside diameter.

Inside diameter : 0.7875~0.7880in (20.003~20.014mm)

2. Subtract piston pin diameter from connecting rod bushing inside diameter to determine piston pin fit.

Clearance : 0.0004~0.0010in (0.010~0.027mm)

3. If clearance is not within specification, replace connector rod bushing.

4. Check each connecting rod for bending.

5. Replace connecting rod if necessary.

Connecting rods must always be replaced as an assembly. Rod cap, rod bolts and nuts are mached
set.

Engine Mechanical System

Cylinder Block - Crankshaft

Engine Mechanical System

2001 > 1.8L DOHC >

INSPECTION

1. Check crankshaft bearing and crank pin journal for damage and scoring.

2. Check oil holes for clogging.

3. Set crankshaft on V-blocks.

4. Measure crankshaft run-out at center journal.

Replace crankshaft if it is not within specification.

Runout : 0.0016in (0.04mm)

5. Use a micrometer to measure crankshaft main bearing journals and crank pin journals at X and Y direction

as shown.

6. Grind crankshaft only if there is visible scoring or if out-of-round is excessive.

7. Only grind crankshaft amount necessary to correct condition.

8. If crankshaft must be ground 0.020in (0.50mm) or more, heat-treat crankshaft to ensure durability.
