10. INSPECT PISTON RING GROOVE CLEARANCE
Using a feeler gauge, measure the clearance between new pis-
ton ring and the wall of the ring groove.
Ring groove clearance:
0.030
− 0.070 mm (0.0012 − 0.0028 in.)
If the clearance is not as specified, replace the piston.
11. INSPECT PISTON RING END GAP
(a) Insert the piston ring into the cylinder bore.
(b) Using a piston, push the piston ring a little beyond the bot-
tom of the ring travel, 110 mm (4.33 in.) from the top of the
cylinder block.
(c) Using a feeler gauge, measure the end gap.
Standard end gap:
No.1 0.25
− 0.35 mm (0.0098 − 0.0138 in.)
No.2 0.35 − 0.50 mm (0.0138 − 0.0197 in.)
Oil (Side rail) 0.15 − 0.40 mm (0.0059 − 0.0157 in.)
Maximum end gap:
No.1 1.05 mm (0.0413 in.)
No.2 1.20 mm (0.0472 in.)
Oil (Side rail) 1.05 mm (0.0413 in.)
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 80 − 90 ° C (176 − 194 ° F), you should be able to push the pis-
ton 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.
S
Check for out − of − alignment
Maximum out − of alignment:
0.05 mm (0.0020 in.) per 100 mm (3.94 in.)
If out − of alignment is greater than maximum, replace the con-
necting rod assembly.
