Removal
NOTE: ldentify valves and valve springs as they areremoved so that each item can be reinstalled in its origi-nal position.
1. Tap e€ch valve stem with a plastic mallet to loosen
valve keepers before installing the spring compres-sor.
Install the spring compressor. Compress spring andremove valve keeper.

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.

Cylinder Head
Wapage
NOTE: lf camshaft-to-holder oil clearances (see page 6
22) arc nol within specification, the head cannot be
resurfaced.
lf camshaft-to-holder oil clearances are within specifica-
tions, check the head for warpage.
lf warpage is less than 0.05 mm (0.002 in) cylinder
head resurfacing is not required.
lf warpage is between 0.05 mm (0.002 in) and 0.2 mm
(0.008 in). resurface cylinder head.
Maximum resurface limit is 0.2 mm (0.008 in) based
on a height of 132.0 mm (5.20 in).
Measure along edges, and 3 ways across center.

lnstallation
Install the cylinder head in the reverse order of removal:
NOTE:
. Always use a new head gasket.
. Cylinder head and cYlinder block surface must be
clean.
. "UP" mark on the camshaft pulleys should be at the
to p.
. Do not use the middle cover and lower cover for stor-
ing removed items.
. Clean the middle cover and lower cover before instal-
lation.
. Replace the washer when damaged or deteriorated
L Cylinder head dowel pins and the oil control orifice
must be aligned.
. When hand'ing a metal gasket, care should be
taken not to fold it or damage the contact surface
of the gasket.

NOTE:
a To check the clutch interlock switch and clutch
switch, see section 23.
a The clutch is self-adjusting to compensate Ior wear.
CAUTION: ll there is no clealance between the master
cylinder piston and push rod, the release bearing is held
against the diaphragm spring, which can result in clutch
slippage or other clutch problems.
1. Loosen locknut A, and back off the clutch switch
(or adjusting bolt) until it no longer touches the clutch
peoal.
2. Loosen locknut C. and turn the push rod in or out
to get the specified stroke (@) and height {O) at the
