NOTICE:
Pull up the main bearing cap little by little to the right and
the left by turns and pay attention not to damage the joint
surface of the cylinder block and the main bearing cap.
HINT:
Keep the lower bearing and main bearing cap together.
Arrange the main bearing caps and lower thrust washers
in correct order.

NOTICE:
Do not turn the crankshaft.
(j) Remove the main bearing caps. (See steps (a) to (c) )
(k) Measure the Plastigage at its widest point.
Standard oil clearance:
No.1 and No.4 journals0.014 ± 0.036 mm (0.0006 ± 0.0014 in.)
No.2 and No.3 journals0.026 ± 0.048 mm (0.0010 ± 0.0019 in.)
Maximum clearance:
No.1 and No.4 journals0.05 mm (0.0020 in.)
No.2 and No.3 journals0.06 mm (0.0024 in.)

29. 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.
30. 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 the correct order only.
31. 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 remove the connecting rod.
HINT:
The piston and pin are a matched set.
Arrange the pistons, pins, rings, connecting rods and
bearings in the correct order.

INSPECTION
1. REMOVE GASKET MATERIAL
Using a gasket scraper, remove all the gasket material from the
top surface of the cylinder block.
2. CLEAN CYLINDER BLOCK
Using a soft brush and solvent, thoroughly clean the cylinder
block.
NOTICE:
If the cylinder is washed at high temperatures, the cylinder
liner sticks out beyond the cylinder block, so always wash
the cylinder block at a temperature of 45°C (113°F) or less.
3. INSPECT TOP SURFACE OF CYLINDER BLOCK FOR
FLATNESS
Using a precision straight edge and feeler gauge, measure the
surface contacting the cylinder head gasket for warpage.
Maximum warpage: 0.07 mm (0.0028 in.)
If warpage is greater than maximum, replace the cylinder block.
4. INSPECT CYLINDER FOR VERTICAL SCRATCHES
Visually check the cylinder for vertical scratches.
If deep scratches are present, replace the cylinder block.

If the end gap is greater than maximum, replace the piston ring.
If the end gap is greater than maximum, even with a new piston
ring, replace the cylinder block.
12. INSPECT PISTON PIN FIT
At 60°C (140°F), you should be able to push the piston pin into
the piston pin hole with your thumb.
13. INSPECT CONNECTING ROD ALIGNMENT
Using a rod aligner and feeler gauge, check the connecting rod
alignment.
Check for out±of±alignment.
Maximum out±of±alignment:
0.05 mm (0.0020 in.) per 100 mm (3.94 in.)
If bend is greater than maximum, replace the connecting rod as-
sembly.
Check for twist
Maximum twist:
0.15 mm (0.0059 in.) per 100 mm (3.94 in.)
If twist is greater than maximum, replace the connecting rod as-
sembly.
14. INSPECT PISTON PIN OIL CLEARANCE
(a) Using a caliper gauge, measure the inside diameter of the
connecting rod bushing.
Bushing inside diameter:
22.005 ± 22.014 mm (0.8663 ± 0.8667 in.)
