Valve Guide Servicing

NOTE: Manufacturer recommends using new valve guides whenever valves are replaced.

Fig 1: Removing Valve Guide Bushing and Reaming to Proper Clearance

Measure clearance between valve stem and valve guide bushing. If clearance is greater than 0.003" (0.08 mm) for intake or 0.004" (0.10 mm) for exhaust, replace valve and/or guide bushing.
Break off upper half of valve guide and heat cylinder head to 176-212°F (80-100°C). Using guide replacement tool (09201-60011), drive out guide bushing toward combustion chamber.
Apply thin coat of oil to guide and guide hole. Drive guide in until snap ring contacts head. Ream guide to achieve proper clearance.
