БЛОК ДВИГАТЕЛЯ - ПРОВЕРКА
| 1. INSPECT CAMSHAFT |
Inspect the circle runout.
Place the camshaft on V-blocks.
Using a dial indicator, measure the circle runout at the center journal.
- Maximum circle runout:
- 0.10 mm (0.00394 in.)
If the circle runout is more than the maximum, replace the camshaft.
Using a micrometer, measure the cam lobe height.
- Standard Cam Lobe Height:
Cam Lobe Specified Condition Intake 54.890 to 54.910 mm (2.1610 to 2.1618 in.) Exhaust 54.990 to 55.010 mm (2.1650 to 2.1657 in.)
- Minimum Cam Lobe Height:
cam Lobe Specified Condition Intake 54.39 mm (2.141 in.) Exhaust 54.49 mm (2.145 in.)
If the cam lobe height is less than the minimum, replace the camshaft.
| 2. INSPECT INTAKE MANIFOLD |
Using a precision straightedge and feeler gauge, measure the surface that contact the cylinder head for warpage.
- Maximum warpage:
- 0.40 mm (0.0157 in.)
If the warpage is more than the maximum, replace the intake manifold.
| 3. INSPECT EXHAUST MANIFOLD |
Using a precision straightedge and feeler gauge, measure the surface that contact the cylinder head for warpage.
- Maximum warpage:
- 0.40 mm (0.0157 in.)
If the warpage is more than the maximum, replace the exhaust manifold.
| 4. INSPECT CYLINDER HEAD SET BOLT |
Using a vernier caliper, measure the minimum outer diameter of the elongated thread at the measuring point.
- Standard outer diameter:
- 11.80 to 12.00 mm (0.465 to 0.472 in.)
- Minimum outer diameter:
- 11.60 mm (0.457 in.)
| *a | Measuring Point |
| *b | Elongated Thread |
If the diameter is less than the minimum, replace the cylinder head set bolt.
