3. Crankshaft removal
1) Measure the crankshaft thrust clearance using a feeler gauge.
Standard: 0.04 to 0.22 mm { 0.0016 to 0.0087 in }
Note
- Replace the thrust bearing if the measured value is outside the standard range.
2) Loosen the bearing cap bolts in the order shown in the diagram.
3) Remove the bearing cap from the cylinder block.
Caution
- Do not reuse the bearing cap bolt.
However, only when a new bearing cap bolt is used to measure the oil clearance, the bearing cap bolt can be reused.
4) Remove the lower crankshaft bearing from the bearing cap.
Note
- If reusing the crankshaft bearings, put number tags on the crankshaft bearings.
5) Remove the crankshaft from the cylinder block.
6) Remove the thrust bearing from the cylinder block.
7) Remove the upper crankshaft bearing from the cylinder block.
Note
- If reusing the crankshaft bearings, put number tags on the crankshaft bearings.
