1. Heat the cylinder head to 80 to 100°C (176 to 212°F).
   

2. Place the cylinder head on wooden blocks.
   

3. Using SST and a hammer, tap out the guide bush.
   

   SST

   09201-10000   (09201-01050)
   

4. Using a caliper gauge, measure the bush bore diameter of the cylinder head.
   

   Cylinder bore diameter:

   9.685 to 9.706 mm (0.3813 to 0.3821 in.)
   

   Select a New Guide Bush (STD or O/S 0.05):

   Bush Size	Bush Bore Diameter
   STD	9.727 to 9.738 mm (0.3830 to 0.3834 in.)
   O/S 0.05	9.777 to 9.788 mm (0.3849 to 0.3854 in.)

   If the bush bore diameter of the cylinder head is greater than 9.706 mm (0.3821 in.), machine the bush bore to the dimension of 9.735 to 9.756 mm (0.3833 to 0.3841 in.) to install an O/S 0.05 valve guide bush.
   

5. Heat the cylinder head to 80 to 100°C (176 to 212°F).
   

6. Place the cylinder head on wooden blocks.
   

7. Using SST and a hammer, tap a new guide bush into the specified protrusion height.

   Protrusion height:

   9.4 to 10.0 mm (0.3701 to 0.3937 in.)
   

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

   Standard oil clearance:

   0.025 to 0.060 mm (0.0010 to 0.0024 in.)
   

1. Heat the cylinder head to 80 to 100°C (176 to 212°F).
   

2. Place the cylinder head on wooden blocks.
