4. INSPECT PISTON 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. (110 mm (4.33 in.) from the top surface of cylinder block) (c) Using a thickness gauge, measure the end gap. Ring end gap: No.1 No.2 Oil STD Limit STD Limit STD Limit 7M-GE 0.23 - 0.38 0.68 0.10 - 0.40 1.00 (0.0091 - 0.0150) (0.0268) 0.25 - 0.53 1.13 (0.0039 - 0.0157) (0.0394) 7M-GTE 0.29 - 0.44 0.74 (0.0098 - 0.0209) (0.0445) (0.0114 - 0.0173) (0.0291) -Δo- 0.10 - 0.44 1.04 (0.0039 - 0.0173) (0.0409) If the diameter is greater than maximum, rebore all six cylinders, or replace the cylinder block. 5. CHECK PISTON PIN FIT At 60°C (140°F) you should be able to push the pin into the piston with your thumb. If the pin can be installed at a lower temperature, replace the piston. 6. INSPECT CONNECTING ROD (a) Using a rod aligner and thickness gauge, check the connecting rod alignment. • Check for bend: Maximum bend: 0.05 mm (0.0020 in.) per 100 mm (3.94 in.) If bend is greater than maximum, replace the connecting rod assembly. • 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 assembly.
