2. Remove:   

• valve guide   

NOTE

:

 

To ease guide removal, installation and to 

maintain correct fit, heat the cylinder head to 

100 °C (212 °F) in an oven. 

 

a. Install the new valve guide using a valve guide 

remover 

①

 and valve guide installer 

②

.  

 

b. After installing the valve guide, bore the valve 

guide using a valve guide reamer 

③

 to obtain 

proper stem-to-guide clearance.   

 

NOTE

:

 

After replacing the valve guide reface the 
valve seat.   

 

 

 

 

 

 

c. If the valve seat is to wide or narrow or cracked, 

grind it to ensure impermeability.   

3. Lap:   

• valve face   

• valve seat   

NOTE

: 

 

After reface the valve seat or replacing the 

valve and valve guide, the valve seat and valve 

face should be lapped.
