Using a caliper gauge, measure the bush bore diameter of the cylinder head side.
- Maximum diameter:
- 11.065 mm (0.4356 in.)
If the bush bore diameter of the cylinder head is 11.065 mm (0.4356 in.) or more, replace the cylinder head.
 |
Select a new guide bush (STD or O/S 0.05), and measure its diameter.
Machine the bush bore diameter of the cylinder head side to the diameter of the selected guide bush.
- Bush bore diameter:
Bush size Specified Condition STD 10.985 to 11.006 mm (0.4325 to 0.4333 in.) O/S 0.05 11.056 to 11.065 mm (0.4353 to 0.4356 in.)
Gradually heat the cylinder head to approximately 80 to 100°C (176 to 212°F).

- Standard protrusion height (H):
- 9.0 to 9.4 mm (0.354 to 0.370 in.)
 |
Using a sharp 6.0 mm reamer, ream the guide bush to obtain the standard specified clearance between the guide bush and valve stem.

| 3. REPLACE CYLINDER HEAD RING PIN |
- ПРИМЕЧАНИЕ:
- It is not necessary to remove the ring pin unless it is being replaced.
Remove the ring pins.
Using a plastic-faced hammer, tap in a new ring pin to the cylinder head.
| 4. REPLACE CYLINDER HEAD TIGHT PLUG |
- ПРИМЕЧАНИЕ:
- If water leaks from the tight plug or the plug corrodes, replace it.
Remove the tight plugs.
Apply adhesive around 2 new tight plugs.
- Adhesive:
- Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent
