Using a 45° cutter, cut the seat to the proper width.
Make sure that all pitting and irregularities are
removed.
CAUTION:
• Excessive lapping pressure may deform or dam-
age the seat.
• Change the angle of lapping tool frequently to
prevent uneven seat wear.
• Lapping compound can cause damage if it
enters between the valve stem and guide.
