VALVESEAT
Renew the valve seats in the cylinder head using avalve seat cutter.
NOTE: lf guides are worn (see page 6-26), replace
them {see page 6-27) before cutting the valve seats.
Carefully cut a 45" seat, removing only enoughmaterial to ensure a smooth and concentric seat.
Bevel the upper edge of the seat with the 30. cutterand the lower edge of the seat with the 60. cutter.Check width of seat and adjust accordingly.
Make one more very light pass with the 45o cutter toremove any possible burrs caused by the other cut-rers.

Standard {New}: 1.25 - 1.55 mm {0.0/t{, - 0.061 in}
S€rvice Limit: 2.0 mm 10.08 in)
After resurfacing the seat, inspect for even valveseating: Apply Prussian Blue compound to the valveface. Insert the valve in its original location in thehead, then lift it and snap it closed against the seatseveral times.
PRUSSIAN BLUE COMPOUNO
6-29
o.The actual valve seating surface, as shown by theblue compound, should be centered on the seat.
lf it is too high (closer to the valve stem), you
must make a second cut with the 60" cutter tomove it down, then one more cut with the 45"
cutter to restore seat width.
lf it is too low (closer to the valve edge), you
must make a second cut with the 30. cutter tomove at up, then one more cut with the 45. cutterto restore seat width.
NOTE: The final cut should always be made with
the 45" cutter.
Insert intake and exhaust valves in the head andmeasure valve stem installed height.

lf the old quarter glass is to be reinstalled (and
either of the clips are broken off the molding), seal
the body holes with pieces of urethane tape. Set the
quarter glass upright in the opening, make align-
ment marks across the quaner glass and body with
a grease pencil at the three points shown, then
remove the quarter glass.

lightly wipe it off with gauze or cheesecloth.
NOTE:
. Do not apply body primer to the quarter glass,
and do not get body and glass primer sponges
mixed up.
. Never touch the primed surfaces with your
hands. lf you do, the adhesive may not bond to
the quarter glass properly, causing a leak after
the quarter glass is installed.
. Keep water, dust, and abrasive materials away
