13. Check fit between piston and piston p in.

Try to move the piston back and forth on the piston p in. If any movement is felt, replace piston and
piston pin as a set.

14. Remove piston rings.

1. Using a piston ring expender, remove the 2 compression rings.

2. Remove 2 side rails and the spacer by hand.

15. Disconnect connecting rod from piston.

Using a press, remove the piston pin from piston. (Press-in load: 800-1400 kg (1764-3086 lbs.)

INSPECTION

CONNECTING ROD AND CRANKSHAFT

1. Check the connecting rod end play.

Using a feeler gauge, measure the end play while moving the connecting rod back and forth.

NOTE:

Arrange the main bearings and thrust bearings in the correct order.

NOTE:

Arrange the piston rings in the correct order only.



If out-of-tolerance, install a new connecting rod.



If still out-of-tolerance, replace the crankshaft.

2. Check the connecting rod bearing oil clearance.

1. Check the matchmarks on the connecting rod and cap are aligned to ensure correct reassembly.

2. Remove 2 connecting rod cap bolts.

3. Remove the connecting rod cap and bearing half.

4. Clean the crank pin and bearing.

5. Place plastigage across the crank p in.

6. Reinstall the bearing half and cap, and torque the bolts.

Tightening torque

19.6 N.m (2.0 kgf.m, 14.46 lb-ft) + 90°

7. Remove 2 bolts, connecting rod cap and bearing-half.

8. Measure the plastigage at its widest point.

Standard oil clearance

0.038-0.056 mm (0.0015-0.0022 in.)

NOTE:

Do not turn the crankshaft.

9. If the plastigage measures too wide or too narrow, remove the upper half of the bearing, install a

new, complete bearing with the same color mark (select the color as shown in the next column),
and recheck the clearance.

10. If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing (the

color listed above or below that one), and check clearance again.

CONNECTING ROD MARK LOCATION

CAUTION: Do not file, shim, or scrape the bearings or the caps to adjust

clearance.

NOTE:

If the proper clearance cannot be obtained by using the appropriate
larger or smaller bearings, replace the crankshaft and start over.

CAUTION: If the marks are indecipherable because of an accumulation of

dirt and dust, do not scrub them with a wire brush or scraper.
Clean them only with solvent or detergent.
