Standard value:
- No. 1 ring: 0.03 - 0.07 mm
No. 2 ring: 0.03 - 0.07 mm
PISTON RINGS |
|
1.Check clearance between piston rings and ring grooves. If the limit is exceeded, replace
piston rings or piston, or both. Standard value:
No. 2 ring: 0.03 - 0.07 mm |
) |
2.Put piston rings into the cylinder bore, press them against the piston top face, and push
them in. After achieving squareness, measure the end gap with a thickness gauge. If the end
gap is excessive, replace piston rings. Standard value:
No. 1 ring: 0.15 - 0.25 mm <4B12> No. 2 ring: 0.30 - 0.45 mm <4B11> No. 2 ring: 0.25 - 0.40 mm <4B12> Oil ring: 0.10 - 0.35 mm
No. 2 ring: 0.8 mm Oil ring: 1.0 mm |
CRANKSHAFT PIN OIL CLEARANCE (PLASTIGAGE METHOD) |
| 1.Wipe oil off the crankshaft pin and connecting rod bearing. |
| 2.Place a Plastigage in length equal to the bearing width on the pin shaft straight
in alignment with the shaft centre. |
) |
3.Carefully install the connecting rod cap and tighten bolts to the specified torque of
5.0 N·m → 20 N·m → +90°. 4.Remove bolts and gently remove the connecting rod cap. |
) |
5.Measure the crushed Plastigage width (area most widely crushed) using a scale printed
on the Plastigage bag. Standard value: 0.018 - 0.045 mm Limit: 0.1 mm |
