(c) Measure the end gap using a thickness
gauge (Figure 5-119).
Figure 5-119
Figure 5-119
Standard end gap:
• No. 1 ring: 0.270 to 0.470 mm (0.011 to
0.018 in.)
• No. 2 ring: 0.400 to 0.650 mm (0.016 to
0.025 in.)
• Oil ring: 0.200 to 0.500 mm (0.025 to 0.020 in.)
Maximum end gap:
• No. 1 ring: 0.85 mm (0.0334 in.)
• No. 2 ring: 0.90 mm (0.0354 in.)
• Oil ring: 0.88 mm (0.0346 in.)
Note: If the end gap exceeds the specified
maximum, replace the piston ring. If the
end gap still exceeds the maximum even
when a new piston ring is used, bore all
six cylinders or replace the cylinder
block.
9. Inspect the piston pin fit to the piston. If the
piston pin can be pressed into the piston by
hand after heating the piston to about 80°C, the
fit is acceptable (Figure 5-120).

10. Measure the bend of the connecting rod using a
rod aligner (Figure 5-121, (1)) and thickness
gauge.
• Maximum bend: 0.03 mm (0.001 in.) per
100 mm (3.936 in.)
If the measured bend exceeds the specified
maximum, replace the connecting rod assembly.
