3. Heat cylinder head to 110 to 120ÉC (230 to 248ÉF) by soaking
in heated oil.
4. Sufficiently cool valve seat with dry ice. Force fit valve seat into
cylinder head.
WARNING:
Do not touch cold valve seat with your bare hands.
5. Cut or grind valve seat using suitable tool to the specified
dimensions as shown in SDS (EM-245).
CAUTION:
Use the valve seat cutter properly. Securely gripping the cut-
ter handle with both hands, press the cutter down onto the
entire circumference of the contacting surface and finish cut-
ting at one time. Improper pressing of the cutter or cutting in
several steps may result in staged surface on the valve seat.
6. After cutting, lap valve seat with abrasive compound.
7. Check valve seating condition. Refer to EM-207, ªValve Seatsº.
JEM253G
8. Use a depth gauge to measure the distance between the
mounting surface of the cylinder head spring seat and the
valve stem end. If the distance is shorter than specified, repeat
step 5 above to adjust it. If it is longer, replace the valve seat
with a new one.
