Cylinder Head -- Replacement |
| 1. REMOVE NO. 2 OIL SEAL RETAINER OIL SEAL |
Using a screwdriver and hammer, tap out the oil seal.
- HINT:
- Tape the screwdriver tip.
| 2. REMOVE INTAKE VALVE GUIDE BUSH |
Gradually heat the cylinder head to approximately 80 to 100°C (176 to 212°F).
Using SST and a hammer, tap out the valve guide bushing.

| 3. REMOVE EXHAUST VALVE GUIDE BUSH |
Gradually heat the cylinder head to approximately 80 to 100°C (176 to 212°F).
Using SST and a hammer, tap out the valve guide bushing.

| 4. INSTALL INTAKE VALVE GUIDE BUSH |
Using a caliper gauge, measure the bush bore diameter of the cylinder head.
- Maximum diameter:
- 13.075 mm (0.5148 in.)
If the bush bore diameter of the cylinder head is greater than 13.025 mm (0.5128 in.), proceed to the next step.
If the bush bore diameter of the cylinder head is greater than 13.075 mm (0.5148 in.), replace the cylinder head.
Machine the bush bore diameter to between 13.054 and 13.075 mm (0.5139 to 0.5148 in.). Then select a new guide bush (STD or O/S 0.05).
- Bush bore diameter:
Bush Size
| Specified Condition
|
STD
| 13.004 to 13.025 mm (0.5120 to 0.5128 in.)
|
O/S 0.05
| 13.054 to 13.075 mm (0.5139 to 0.5148 in.)

Gradually heat the cylinder head to approximately 80 to 100°C (176 to 212°F).
Using SST and a hammer, tap in a new guide bush to the specified protrusion height.
- SST
- 09201-10000(09201-01080)
09950-70010(09951-07100)
- Standard protrusion height (H):
- 10.8 to 11.2 mm (0.425 to 0.441 in.)
Using a sharp 8.0 mm reamer, ream the guide bush to obtain the standard specified clearance between the guide bush and valve stem.
| 5. INSTALL EXHAUST VALVE GUIDE BUSH |
Using a caliper gauge, measure the bush bore diameter of the cylinder head.
- Maximum diameter:
- 13.075 mm (0.5148 in.)
If the bush bore diameter of the cylinder head is greater than 13.025 mm (0.5128 in.), proceed to the next step.
If the bush bore diameter of the cylinder head is greater than 13.075 mm (0.5148 in.), replace the cylinder head.
Machine the bush bore diameter to between 13.054 and 13.075 mm (0.5139 to 0.5148 in.). Then select a new guide bush (STD or O/S 0.05).

- 10.8 mm to 11.2 mm (0.425 to 0.441 in.)
Using a sharp 8.0 mm reamer, ream the guide bush to obtain the standard specified clearance between the guide bush and valve stem.
| 6. INSTALL NO. 2 OIL SEAL RETAINER OIL SEAL |
Using SST and a hammer, tap in a new oil seal until its surface is flush with the oil seal retainer edge.
- SST
- 09223-46011
Apply MP grease to the lip of the oil seal.
