Note. Typical cylinder head shown in illustration.

  1. Remove carbon and varnish deposits from inside of the valve guides with a reliable guide cleaner.
  2. Measure valve stem-to-guide clearance as follows
  3. Install the valve (2) into the cylinder head so that it is 15 mm (0.590 inch.) off of the valve seat. A small piece of hose may be used to hold the valve in place.
  4. Attach the Dial Indicator Set (special tool #C-3339A, Set, Dial Indicator) (1) to the cylinder head and set it at a right angle to the valve stem being measured.
  5. Move the valve to and from the indicator. Compare this reading to the specification. Refer to «ENGINE SPECIFICATIONS»(ref-646215-S03916579012014072800000) .

Note. If stem-to-guide clearance exceeds specifications, you must measure the valve stem. If the valve stem is within specification or if the valve guide is loose in the cylinder head, replace the cylinder head.
