Valve Guides

  1. Measure diameter of valve guide and valve stem. Maximum clearance for exhaust valves is .0039" (.10 mm). Maximum clearance for intake valves is .0031" (.08 mm). If valve stem oil clearance exceeds specification, valve guides and valves must be replaced. Break off end of guide using punch and hammer. Heat cylinder head to about 194°F (90°C).
  2. Using Valve Guide Remover (09201-60011) and hammer, drive old guide out through combustion chamber. Install new valve guide from top of head until snap ring contacts cylinder head. Ream valve guide with a .31" (8 mm) reamer for proper stem clearance.
