Standard cylinder bore diameter

10.285 to 10.306 mm (0.405 to 0.406 in.)

If the bush bore diameter of the cylinder head is between 10.285 to 10.306 mm (0.405 to 0.406 in.), proceed to the next step.

If the bush bore diameter of the cylinder head is 10.356 mm (0.408 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	10.333 to 10.344 mm (0.4068 to 0.4072 in.)
O/S 0.05	10.383 to 10.394 mm (0.4088 to 0.4092 in.)

Standard bush length

41.3 to 41.7 mm (1.63 to 1.64 in.)

Using SST and a hammer, tap in a new guide bush to the standard protrusion height.

Standard protrusion height

15.8 to 16.2 mm (0.622 to 0.638 in.)

Using a sharp 5.5 mm reamer, ream the guide bush to obtain the standard oil clearance between the guide bush and valve stem.

Standard oil clearance

0.025 to 0.060 mm (0.000984 to 0.00236 in.)
