9. INSPECT VALVE STEMS AND GUIDE BUSHINGS
(a)
Using a caliper gauge, measure the inside diameter of the
guide bushing.
Bushing inside diameter:
6.010 -- 6.030 mm (0.2366 -- 0.2374 in.)
(b)
Using a micrometer, measure the diameter of the valve
stem.
Valve stem diameter:
Intake
5.970 -- 5.985 mm (0.2350 -- 0.2356 in.)
Exhaust
5.965 -- 5.980 mm (0.2348 -- 0.2354 in.)
(c)
Subtract the valve stem diameter measurement from the
guide bushing inside diameter measurement.
Standard oil clearance:
Intake
0.025 -- 0.060 mm (0.0010 -- 0.0024 in.)
Exhaust
0.030 -- 0.065 mm (0.0012 -- 0.0026 in.)
Maximum oil clearance:
Intake
0.08 mm (0.0031 in.)
Exhaust
0.10 mm (0.0039 in.)
If the clearance is greater than maximum, replace the valve and
guide bushing.
10. IF NECESSARY, REPLACE VALVE GUIDE
BUS HI NG S
(a)
Gradually heat the cylinder head to 80 -- 100
˚
C
(176 -- 212
˚
F).
(b)
Using SST and a hammer, tap out the guide bushing.
SST 09201 -- 10000 (09201 -- 01060),
09950 -- 70010 (09951 -- 07150)
(c)
Using a caliper gauge, measure the bushing bore diame-
ter of the cylinder head.
