PROCEDURE

1. REMOVE NO. 1 VENTILATION CASE

2. REMOVE CYLINDER BLOCK WITH HEAD STRAIGHT SCREW PLUG

(1) Using a 10 mm hexagon socket wrench, remove the cylinder block with head straight screw plug and gasket from the cylinder block sub-assembly.

3. INSPECT CONNECTING ROD THRUST CLEARANCE

(1) Using a dial indicator, measure the thrust clearance while moving the connecting rod sub-assembly back and forth.

Standard Thrust Clearance:

0.160 to 0.512 mm (0.00630 to 0.0202 in.)

Maximum Thrust Clearance:

0.512 mm (0.0202 in.)

HINT:

If the thrust clearance is more than the maximum, replace the connecting rod. If necessary, replace the crankshaft.

4. INSPECT CONNECTING ROD OIL CLEARANCE

*a

Alignment Mark

-

-

(1) Note the alignment marks on the connecting rod and connecting rod cap so that they can be reinstalled to their original locations.

(2) Using an E12 "TORX" socket wrench, remove the 2 connecting rod bolts and connecting rod cap.

(3) Clean the crank pin and connecting rod bearing.

NOTICE:

Check the crank pin and connecting rod bearing for pitting and scratches.

HINT:

If the crank pin or connecting rod bearing is damaged, replace the connecting rod bearings. If necessary, replace the crankshaft.

Plastigage

*b

Front Mark

*c

Paint Mark

*d

90°

*e

1, 2 or 3 Mark

-

-

Front of Engine

-

-

(1) Lay a strip of Plastigage on the crank pin.

(2) Check that the front mark of the connecting rod cap is facing the correct direction, and install the connecting rod cap to the connecting rod.

(3) Apply a light coat of engine oil to the threads and under the heads of the 2 connecting rod bolts.

(4) Using an E12 "TORX" socket wrench, install and alternately tighten the 2 connecting rod bolts in several steps.

Torque:

38 N·m {387 kgf·cm, 28 ft·lbf}

(5) Mark the front of each connecting rod bolt with paint.

(6) Tighten the connecting rod bolts 90° as shown in the illustration.

NOTICE:

Do not turn the crankshaft during the measurement.

(7) Remove the 2 connecting rod bolts and connecting rod cap.

HINT:

Keep the connecting rod bearing and connecting rod cap together.

(8) Measure the Plastigage at its widest point.

Standard Oil Clearance:

0.032 to 0.065 mm (0.00126 to 0.00256 in.)

Maximum Oil Clearance:

0.065 mm (0.00256 in.)

HINT:

  • If the oil clearance is more than the maximum, replace the connecting rod bearings. If necessary, replace the crankshaft.
  • If replacing a connecting rod bearing, select a new one with the same number as marked on the connecting rod cap. There are 3 sizes of standard connecting rod bearings, marked "1", "2" or "3" accordingly.

Standard Connecting Rod Big End Inside Diameter:

Mark

Specified Condition

1

51.000 to 51.008 mm (2.00787 to 2.00818 in.)

2

51.008 to 51.016 mm (2.00818 to 2.00850 in.)

3

51.016 to 51.024 mm (2.00850 to 2.00881 in.)

Standard Connecting Rod Bearing Center Wall Thickness:

Mark

Specified Condition

1

1.483 to 1.487 mm (0.05839 to 0.05854 in.)

2

1.487 to 1.491 mm (0.05854 to 0.05870 in.)

3

1.491 to 1.495 mm (0.05870 to 0.05886 in.)

Standard Crank Pin Diameter:

47.992 to 48.000 mm (1.88945 to 1.88976 in.)

NOTICE:

Remove the Plastigage completely after the measurement.

5. REMOVE PISTON WITH CONNECTING ROD

(1) Using a ridge reamer, remove all the carbon from the top of each cylinder.

(2) Remove the 8 connecting rod bolts, 4 connecting rod caps and 4 connecting rod bearings.

(3) Push the 4 pistons, 4 connecting rods and 4 connecting rod bearings out through the top of the cylinder block sub-assembly.

HINT:

  • Keep the connecting rod bearings, connecting rods and connecting rod caps together.
  • Arrange the removed parts in such a way that they can be reinstalled to their original locations.

6. REMOVE CONNECTING ROD BEARING

7. INSPECT CRANKSHAFT THRUST CLEARANCE

(1) Using a dial indicator, measure the crankshaft thrust clearance while prying the crankshaft back and forth with a screwdriver.

Standard Thrust Clearance:

0.02 to 0.22 mm (0.000787 to 0.00866 in.)

Maximum Thrust Clearance:

0.22 mm (0.00866 in.)

HINT:

If the thrust clearance is more than the maximum, replace the crankshaft thrust washers as a set. If necessary, replace the crankshaft.
