(a) Using SST and a hammer, tap in a new guide bush to the specified protrusion height. Protrusion height: 9.6 to 10.0 mm (0.3779 to 0.3937 in.)
SST 09201-10000 (09201-01050), 09950-70010 (09951-07100)
(b) 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.) 21. 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.
(c) Using SST and a hammer, tap in a new guide bush to the specified protrusion height.
(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.
SST 09201-10000 (09201-01050), 09950-70010
(09951-07100) Standard oil clearance: 0.030 to 0.065 mm (0.0012 to 0.0026 in.)
22. INSPECT VALVE LIFTER
(a) Using a micrometer, measure the lifter diameter. Lifter diameter:
(b) Using a caliper gauge, measure the lifter bore diameter of the cylinder head.
Lifter bore diameter:
(c) Subtract the lifter diameter measurement from the lifter bore diameter measurement.
Specified oil clearance:
If the oil clearance is greater than the maximum, replace the lifter. If necessary, replace the cylinder head.
INSTALL RING W/HEAD PIN
Using a plastic-faced hammer, tap in a new ring pin to the specified protrusion height. Protrusion height: 3 mm (0.12 in.)
INSTALL STUD BOLT Torque:
5 N m (51 kgf cm, 44 in. Ibf) for bolt A 5 N m (51 kgf cm, 44 in. Ibf) for bolt B 10 N m (97 kgf cm, 7 ft Ibf) for bolt C 10 N m (97 kgf cm, 7 ft Ibf) for bolt D
25. INSTALL VALVE SPRING SEAT
Intake Side Exhaust Side
26. INSTALL VALVE STEM OIL O SEAL OR RING
(a) Apply a light coat of engine oil on a new oil seal. NOTICE:
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.
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
27. 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.
(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. NOTICE:
Be careful not to damage the valve stem tip.
