17. INSTALL EXHAUST VALVE GUIDE BUSH
(a) Using a caliper gauge, measure the bushing bore diame-
ter of the cylinder head.
Diameter: 10.985 ± 11.006 mm (0.4325 ± 0.4333 in.)
If the bushing bore diameter of the cylinder head is greater then
11.006 mm (0.4333 in.), machine the bushing bore to the di-
mension of 11.035 ± 11.056 mm (0.4344 ± 0.4353 in.).

(c) Using SST and a hammer, tap in a new guide bushing to
the specified protrusion height.
SST 09201±10000 (09201±01060), 09950±70010
(09951±07100)
Protrusion height:
9.65 ± 10.05 mm (0.3799 ± 0.3957 in.)
(d) Using a sharp 6 mm reamer, ream the guide bushing to
obtain the standard specified clearance between the
guide bushing and valve stem.
Standard oil clearance:
0.035 ± 0.070 mm (0.0014 ± 0.0028 in.)
18. INSPECT VALVE SEATS

(c) Check the valve face and seat according to the following
procedure.
(1) If blue appears 360
around the face, the valve is
concentric. If not, replace the valve.
(2) If blue appears 360
around the valve seat, the
guide and face are concentric. If not, resurface the
seat.
(3) Check that the seat contact is in the middle of the
valve face with the following width.
Intake1.2 ± 1.6 mm (0.047 ± 0.063 in.)
Exhaust1.6 ± 2.0 mm (0.063 ± 0.079 in.)
19. REPAIR INTAKE VALVE SEATS
NOTICE:
Take off a cutter gradually to make smooth valve seats.
(a) If the seating is too high on the valve face, use 25
and
45
cutters to correct the seat.
(b) If the seating is too low on the valve face, use 70
and
45
cutters to correct the seat.
(c) Hand±lap the valve and valve seat with an abrasive com-
pound.
(d) Check the valve seating position.
