Valve Guide Servicing: Replacement

  1. Using hammer and drift, tap guide firmly enough to break guide off flush with cylinder head surface. Remove snap ring. Gradually heat head to 194°F (90°C). Using Valve Guide Remover (09201-60011), drive guide out from camshaft side.
  2. Measure cylinder head valve guide hole. Standard guide outside diameter is .4543-.4548" (11.540-11.551 mm). If hole-to-guide clearance is excessive, machine hole for oversized guide.
  3. With head at room temperature, ream guide hole to fit new guide. Oversize guide outside diameter is .4563-.4567" (11.590-11.601 mm). To install valve guide, reheat cylinder head.
  4. Using Valve Guide Installer (09201-60011), drive in new guide until snap ring contacts head. Using 7 mm reamer, finish guide bore to specified clearance. Reface valve seat surface, as needed, after valve or guide repair or replacement.
