  1. Using a caliper gauge, measure the bushing bore diameter of the cylinder head.

    Diameter:
    10.985 to 11.006 mm (0.4325 to 0.4333 in.)

    HINT:
    1. If the bushing bore diameter is as specified, install the standard bushing.
    2. If the bushing bore diameter is not as specified, correct it to 11.035 to 11.056 mm (0.4345 to 0.4353 in.) and install the oversize bushing.

  1. Using a reamer, ream the inside of the valve guide bushing to the specified oil clearance between the valve guide bushing and valve stem.

    Standard oil clearance:
    0.025 to 0.060 mm (0.0010 to 0.0024 in.)



2. REPLACE EXHAUST VALVE GUIDE BUSHING


    A069792E01

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

  1. Using SST and a hammer, tap out the valve guide bushing to the combustion camber side.
