VALVE SEAT REPLACEMENT
When valve seat is removed, replace with oversized [0.5 mm (0.020 in)] valve seat.
1.
Bore out old seat until it collapses. Boring should not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this.
2.
Ream cylinder head recess diameter for service valve seat.
●
Be sure to ream in circles concentric to the valve guide center.
●
This will enable valve seat to fit correctly.
3.
Heat cylinder head to 110 to 130
°
C (230 to 266
°
F) by soaking in
heated oil.
4.
Provide valve seats cooled well with dry ice. Force fit valve seat
into cylinder head.
CAUTION:
●
Avoid directly to touching cold valve seats.
●
Cylinder head contains heat. When working, wear protec-
tive equipment to avoid getting burned.
5.
Using valve seat cutter set (commercial service tool) or valve
seat grinder, finish the seat to the specified dimensions.
CAUTION:
When using valve seat cutter, firmly grip the cutter handle
with both hands. Then, press on the contacting surface all
around the circumference to cut in a single drive. Improper
pressure on with the cutter or cutting many different times
may result in stage valve seat.
