1995 TOYOTA SUPRA height

(d) Using SST and a hammer, tap in a new guide bushing to the
specified protrusion height.
SST 09201±10000 (09201±01060), 09608±30022
(09608±05010)
Protrusion height:
Intake
12.3±12.7 mm (0.484±0.500 in.)
Exhaust
11.4±11.8 mm (0.449±0.465 in.)
HINT: Different bushings are used for the intake and exhaust.
(e) Using a sharp 6 mm reamer, ream the guide bushing to obtain
the standard specified clearance (See step 6) between the
guide bushing and valve stem.
7. INSPECT AND GRIND VALVES
(a) Grind the valve enough to remove pits and carbon.
(b) Check that the valve is ground to the correct valve face angle.
Valve face angle:
44.55
(c) Check the valve head margin thickness.
Standard margin thickness:
0.8±1.2 mm (0.031±0.047 in.)
Minimum margin thickness:
0.5 mm (0.020 in.)
If the margin thickness is less than minimum, replace the
valve. EG±54

10. INSPECT CAMSHAFTS AND BEARINGS
A. Inspect camshaft for runout
(a) Place the camshaft on V±blocks.
(b) Using a dial indicator, measure the circle runout at the center
journal.
Maximum circle runout:
0.08 mm ª(0.0031 in.)
If the circle runout is greater than maximum, replace the cam-
shaft.
B. Inspect cam lobes
Using a micrometer, measure the cam lobe height.
Standard cam lobe height:
Intake
44.570±44.670 mm (1.7547±1.7587 in.)
Exhaust
44.770±44.870 mm (1.7626±1.7665 in.)
Maximum cam lobe height:
Intake
44.42 mm (1.7488 in.)
Exhaust
44.62 mm (1.7567 in.)
If the cam lobe height is less than minimum, replace the cam-
shaft.
C. Inspect camshaft journals
Using a micrometer, measure the journal diameter.
Journal diameter:
28.949±28.965 mm (1.1397±1.1404 in.)
If the journal diameter is not as specified, check the oil clear-
ance.
D. Inspect camshaft bearings
Check the bearings for flaking and scoring.
If the bearings are damaged, replace the bearing caps and
cylinder head as a set.
E. Inspect camshaft journal oil clearance
(a) Clean the bearing caps and camshaft journals.
(b) Place the camshafts on the cylinder head.
(c) Lay a strip of Plastigage across each of the camshaft
journals.
