(c) Using a thickness gauge, measure the end gap.
Ring end gap:
Standard No.1 0.25 – 0.47 mm
(0.0098 – 0.0185 in.)
No–2 0.60 – 0.82 mm
(0.0236 – 0.0323 in.)
Oil 0.20 – 0.57 mm
(0.0079 – 0.0224 in.)
Maximum No.1 1.07 mm (0.0421 in.)
No.2 1.42 mm (0.0559 in.)
Oil 1.17 mm (0.0461 in.)
If the gap is greater than maximum, replace the ring.
Do not file the ring end.
6. INSPECT CONNECTING RODS
(a) Using a rod aligner, check the connecting rod align–
ment.
If the rod is bent or twisted, replace the connecting
rod.
• Check that the rod is not bent.
Maximum bend:
0.05 mm (0.0020 in.) per 100 mm (3.94 in.)
5. INSPECT PISTON PIN FIT
At 80C(176 F), you should able to push the pin into
the piston with your thumb.
If the pin can be installed at a lower temperature,
replace it and the piston.
4. MEASURE RING END GAP
(a) Insert the piston ring into the cylinder.
(b) Using a piston, push the ring a little beyond the
bottom of the ring travel.
(130 mm (5.12 in.) from top surface of cylinder block)
