6. Make a paint mark on the bolt end at a position 90 to 94 degrees from the paint
mark made on the nut in the direction of tightening the nut.
7. Turn the nut another 90 to 94 degrees and make sure that the paint marks on
the nut and bolt are aligned.
CAUTION:
If the nut is turned less than 90 degrees,
proper fastening performance may not be
achieved. Be careful to tighten the nut
exactly 90 degrees. If the nut is overtightened (exceeding 94
degrees), loosen the nut completely and then
retighten it by repeating the tightening
procedure from step 3.

INSPECTION PISTON Replace the piston if scratches or seizure is evident on its surfaces (especially the
thrust surface). Replace the piston if it is cracked. PISTON PIN 1. Insert the piston pin into the piston pin hole with a thumb. You should feel a
slight resistance. Replace the piston pin if it can be easily inserted or there is
excessive play.
2. The piston and piston pin must be replaced as an assembly. PISTON RING 1. Check the piston ring for damage, excessive wear, and breakage. Replace if
defects are evident. If the piston has been replaced with a new one, the piston
rings must also be replaced with new ones.
2. Check for clearance between the piston ring and ring groove. If the limit is
exceeded, replace the ring or piston, or both.
Standard Value:
Number 1: 0.03 - 0.07 mm (0.0012 - 0.0027 inch)
Number 2: 0.02 - 0.06 mm (0.0008 - 0.0023 inch)
Limit: 0.1 mm (0.003 inch)

3. Insert the piston ring into the cylinder bore. Force the ring down with a piston,
the piston crown being in contact with the ring, to correctly position it at right
angles to the cylinder wall. Then, measure the end gap with a feeler gauge.

If the ring gap is excessive, replace the piston ring.
Standard value:

1. Remove oil from the crankshaft pin and the bearing inner surface.
2. Cut plastic gauging material to the same length as the width of the bearing and
place it on the pin in parallel with its axis.
3. Install the connecting rod cap carefully and tighten the nuts to the specified
torque.
4. Carefully remove the connecting rod cap.
5. Measure the width of the smashed plastic gauging material at its widest section
by using a scale printed on the plastic gauging material bag.
Standard value: 0.02 - 0.04 mm (0.0008 - 0.0016 inch)
Limit: 0.1 mm (0.003 inch)
