HINT:
If using a standard bearing, replace it with one having the same
number. If the number of the bearing cannot be determined, se-
lect the correct bearing by adding together the numbers im-
printed on the cylinder block and crankshaft, then refer to the
table below for the appropriate bearing number. There are 5
sizes of the standard bearings. For No.1 and No.5 position
bearings, use bearings marked ”3”, ”4”, ”5”, ”6” and ”7”. For oth-
ers position bearings, use bearings marked ”1”, ”2”, ”3”, ”4” and
”5”.

(k)

Completely remove the Plastigage.

24.

REMOVE CRANKSHAFT

(a)

Lift up the crankshaft.

(b)

Remove the 5 upper main bearings and 2 upper thrust
washers from the cylinder block.

HINT:
Arrange the main bearing caps, bearings and thrust washers in
correct order.
25.

CHECK FIT BETWEEN PISTON AND PISTON PIN

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

REMOVE PISTON RINGS

(a)

Using a piston ring expander, remove the 2 compression
rings.

(b)

Remove the 2 side rails and oil ring by hand.

HINT:
Arrange the piston rings in correct order only.

27.

DISCONNECT CONNECTING ROD FROM PISTON

(a)

Using a small screwdriver, pry out the 2 snap rings.

(b)

Gradually heat the piston to approx. 60

°

C (140

°

F).

(c)

Using a plastic–faced hammer and brass bar, lightly tap
out the piston pin and pin and remove the connecting rod.

HINT:



The piston and pin are a matched set.



Arrange the pistons, pins, rings, connecting rods and
bearings in correct order.

INSPECTION

1.

CLEAN CYLINDER BLOCK

(a)

Using a gasket scraper, remove all the gasket material
from the top surface of the cylinder block.

(b)

Using a soft brush and solvent, thoroughly clean the cylin-
der block.

2.

INSPECT CYLINDER BLOCK

(a)

Inspect for flatness.
Using a precision straight edge and feeler gauge, mea-
sure the surfaces contacting the cylinder head and main
bearing cap for warpage.
Maximum warpage: 0.07 mm (0.0028 in.)

If warpage is greater than maximum, replace the cylinder block.

(b)

Visually check the cylinder for vertical scratches.

If deep scratches are present, rebore all the 8 cylinders and re-
place all the 8 pistons. (See page 

EM–116

) If necessary, re-

place the cylinder block.
