- If the intake valve guide bush bore diameter is more than 10.306 mm
(0.406 in.), machine the intake valve guide bush bore to a dimension of
10.335 to 10.356 mm (0.407 to 0.408 in.) to install an O/S 0.05 intake
valve guide bush.
- If the intake valve guide bush bore diameter of the cylinder head LH is
more than 10.356 mm (0.40772 in.), replace the cylinder head LH.

(e) Heat the cylinder head LH to between 80 and 100°C (176 and 212°F).
(f) Place the cylinder head LH on wooden blocks. CAUTION: Be sure to wear protective gloves.
(g) Using SST and a hammer, tap in a new intake valve guide bush to the specified protrusion height.

2. REPLACE EXHAUST VALVE GUIDE BUSH (a) Heat the cylinder head LH to between 80 and 100°C (176 and 212°F).
(b) Place the cylinder head LH on wooden blocks. CAUTION: Be sure to wear protective gloves.
(c) Using SST and a hammer, tap out the exhaust valve guide bush.

(d) Using a caliper gauge, measure the exhaust valve guide bush bore diameter of the cylinder head LH.
Standard Exhaust Valve Guide Bush Bore Diameter: 10.285 to 10.306 mm (0.405 to 0.406 in.)
New Guide Bush Selection Chart:
Bush Size | Bush Bore Diameter |
STD | 10.333 to 10.344 mm (0.40681 to 0.40724 in.) |
O/S 0.05 | 10.383 to 10.394 mm (0.40878 to 0.40921 in.) |
HINT:
- If the exhaust valve guide bush bore diameter is more than 10.306 mm
(0.406 in.), machine the exhaust valve guide bush bore to a dimension of
10.335 to 10.356 mm (0.407 to 0.408 in.) to install an O/S 0.05 exhaust
valve guide bush.
- If the exhaust valve guide bush bore diameter of the cylinder head LH is
more than 10.356 mm (0.40772 in.), replace the cylinder head LH.
