4. Heat cylinder head to 110° to 130°C (230° to 266°F) by soaking
in heated oil (A).
5. Press valve guide (1) from camshaft side to dimensions as
shown.
CAUTION:
Cylinder head contains heat, when working, wear protective
equipment to avoid getting burned.
6. Apply reamer finish to valve guide using suitable tool (A).
VALVE SEAT CONTACT

After confirming that the dimensions of valve guides and valves are within specifications, perform this pro-
cedure.

Apply prussian blue (or white lead) onto contacting surface of valve seat to check the condition of the
valve contact on the surface.

Check if the contact area band is continuous all around the cir-
cumference.

If not, grind to adjust valve fitting and check again. If the contact-
ing surface still has NG conditions even after the re-check,
replace valve seat.
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. Refer to EM-109, "
Valve Seat" .

in heated oil (A).
4. Provide valve seats cooled well with dry ice. Press-fit valve seat into cylinder head.
CAUTION:

Never touch cold valve seats directly.

Cylinder head contains heat, when working, wear protective equipment to avoid getting burned.
5. Using valve seat cutter set or valve seat grinder, finish valve
seat to the specified dimensions. For dimensions, refer to EM-
109, "Valve Seat" .
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.
6. Using compound, grind to adjust valve fitting.
7. Check again for normal contact. Refer to EM-70, "
VALVE SEAT CONTACT" .
VALVE SPRING SQUARENESS

Set try square along the side of valve spring and rotate the
spring. Measure the maximum clearance between the top of
valve spring and try square.
CAUTION:
Never remove valve spring seat from valve spring.

If it exceeds the limit, replace valve spring (with valve spring
seat).

place a torque wrench (A) on the extended line of the flywheel
(2) center line.

Tighten bolt at a force of 9.8 N·m (1.0 kg-m, 87 in-lb) to keep it
