3. INSTALL INTAKE VALVE GUIDE BUSH

(a) Heat the cylinder head to 80 to 100°C (176 to 212°F).
(b) Place the cylinder head on wooden blocks.
(c) Using a caliper gauge, measure the bush bore diameter of the cylinder head.
Standard diameter:
10.285 to 10.306 mm (0.4049 to 0.4058 in.)
(d) Install the STD bush if the diameter is within the specified diameter.
Standard diameter:
10.333 to 10.344 mm (0.4068 to 0.4072 in.)

(e) Using SST and a hammer, tap in a new guide bush to the specified protrusion height.

Standard protrusion height:
9.6 to 10 mm (0.3780 to 0.3937 in.)
(f) Using a sharp 5.5 mm reamer, ream the valve guide bush to the standard specified clearance between the valve guide bush and valve stem.
Standard oil clearance:
0.025 to 0.060 mm (0.0010 to 0.0024 in.)
4. INSTALL EXHAUST VALVE GUIDE BUSH
