3. Press service valve guide into cylinder head using suitable tooluntil the guide projects out 16 0.2 mm (0.63 0.008 in).
4. Ream valve guide. Finished size:8.000 - 8.015 mm (0.3150 - 0.3156 in)
VALVE SEATS
Check valve for any evidence of pitting at valve contact surface,
and reseat or replace if worn out excessively.
IWhen repairing valve seats, check valve and valve guide
for wear beforehand. If worn, replace them. Then correct
valve seat.
I The cutting should be done with both hands for uniform
cutting.
REPLACING VALVE SEAT FOR SERVICE PARTS
1. Before out old seat until it collapses or remove valve seats with
Tool.
Place a copper seat between contact surface of Tool and cyl-
inder head.
2. Place new valve seats on dry ice and allow them to cool for five minutes.
WARNING:
Do not touch cooled valve seats with bare hand.
3. Heat cylinder head to 80ÉC (176ÉF).
4. Install cooled valve seats on cylinder head with Tool.
