Reassembly

2AZ-FE ENGINE MECHANICAL: CYLINDER HEAD:

REASSEMBLY

1. INSTALL INTAKE VALVE GUIDE BUSH
(a) Using a caliper gauge, measure the bush bore diameter of the cylinder head.
Diameter:
10.285 to 10.306 mm (0.4049 to 0.4057 in.)
(b) Install the STD bush if the diameter is within the specified diameter.
Specified diameter:
10.333 to 10.344 mm (0.4068 to 0.4072 in.)

(c) Using SST and a hammer, tap in a new guide bush to the specified protrusion height.
SST: 09201-10000
09201-01050
SST: 09950-70010
09951-07100
Protrusion height:
9.6 to 10.0 mm (0.3779 to 0.3937 in.)
(d) Using a sharp 5.5 mm reamer, ream the guide bush to obtain the standard specified clearance between the guide bush and valve stem.
Standard oil clearance:
0.025 to 0.060 mm (0.0010 to 0.0024 in.)
2. INSTALL EXHAUST VALVE GUIDE BUSH
(a) Using a caliper gauge, measure the bush bore diameter of the cylinder head.
Diameter:
10.285 to 10.306 mm (0.4049 to 0.4057 in.)
(b) Install the STD bush if the diameter is within the specified diameter.
Specified diameter:
10.333 to 10.344 mm (0.4068 to 0.4072 in.)

(a) Using a plastic-faced hammer, tap in a new ring pin to the specified protrusion height.
Protrusion height:
3 mm (0.12 in.)
4. INSTALL STUD BOLT
(a) Install stud bolt.
Bolt A - Torque: 5 Nm (51 kgf-cm, 44 in-lbf)
Bolt B - Torque: 5 Nm (51 kgf-cm, 44 in-lbf)
Bolt C - Torque: 10 Nm (97 kgf-cm, 7 ft-lbf)
Bolt D - Torque: 10 Nm (97 kgf-cm, 7 ft-lbf)

5. INSTALL VALVE SPRING SEAT
6. INSTALL VALVE STEM OIL SEAL

(a) Apply a light coat of engine oil on a new oil seal.

NOTE: Pay close attention when installing the intake and exhaust oil seals. For example, installing the intake oil seal into the exhaust or installing the exhaust oil seal to the intake can cause installation problems later.

HINT: The intake valve oil seal is gray and the exhaust valve oil seal is black.

(b) Using SST, push in the oil seal.
SST: 09201-41020

NOTE: Failure to use SST will cause the seal to be damaged or improperly seated.

7. INSTALL INTAKE VALVE

(a) Install the valve, spring and retainer to the cylinder head.
(b) Using SST and wooden blocks, compress the spring and install the 2 retainer locks.
SST: 09202-70020
09202-00010

(a) Install the valve, spring and retainer to the cylinder head.

NOTE: Install the same parts in the same combination to the original locations.

(b) Using SST and wooden blocks, compress the spring and install the 2 retainer locks.
SST: 09202-70020
09202-00010

(c) Using a plastic-faced hammer and a discarded valve with its tip wrapped in tape, lightly tap the installed valve to ensure that it is securely fit.

NOTE: Be careful not to damage the valve stem tip.

9. INSTALL VALVE LIFTER
(a) Assemble the valve lifter and the tip of the valve stem with a light coat of engine oil applied.

NOTE: Install the valve lifters in their original places.
