INSPECTION
Va l v e
1. Clean valves thoroughly and discard any burned,
bent, warped, and cracked valves.
2. Measure valve stems for wear (Refer to 9 -
ENGINE - SPECIFICATIONS).
NOTE: Valve stems are chrome plated and should
not be polished.
Valve Guide
1. Remove carbon and varnish deposits from inside of
valve guides with a reliable guide cleaner.
2. Measure valve stem guide clearance as follows:
1. Install valve into cylinder head so it is 14 mm
(0.551 in.) off the valve seat. A small piece of hose
maybeusedtoholdvalveinplace.
2. Attach Special Tool C-3339, dial indicator to cyl-
inder head and set it at right angle of valve stem
being measured.
3. Move valve to and from the indicator. (Refer to 9
- ENGINE - SPECIFICATIONS) for valve guide
specifications. If guides are out of specifications,
ream to next oversize.
3. Ream the guides for valves with oversized stems if
dial indicator reading is excessive or if the stems
are scuffed or scored.
4. Service valves with oversize stems and over size seals are available in 0.15 mm (0.005 in.) and 0.40 mm (0.015
in.) oversize.
NOTE: Oversize seals must be used with oversize valves.
5. Select the correct size reamer to accommodate the oversize valve stem. Refer to Valve Guide Oversize Chart.
6. Slowly turn reamer by hand and clean guide thoroughly before installingnew valve.Do not attempt to ream the
valve guides from standard directly to 0.40 mm (0.015 in.). Use a step procedure of 0.15 mm (0.005 in.) to
0.40 mm (0.015 in.), so the valve guides may be reamed true in relation to thevalve seat. After reaming
guides, the seat runout should be measured and resurfaced if necessary. See Refacing Valves and Valve
Seats (Refer to 9 - ENGINE/CYLINDER HEAD/INTAKE/EXHAUST VALVES & SEATS - STANDARD PROCE-
DURE).
NOTE: Replace cylinder head if guide does not clean up with 0.40 mm (0.015 inch) oversize reamer, or if
guide is loose in cylinder head.
