(c) Remove the LH camshafts.
(1) Move a service bolt of the sub-gear upward by turn-
ing the hexagon shaped port of the exhaust cam-
shaft with a wrench.
(2) Secure the sub-gear to the main gear with a service
bolt.
Recommended service bolt:
Thread diameter6 mm
Thread pitch1.0 mm
Bolt length16 - 20 mm
HINT:
When removing the camshaft, make sure that the torsional
spring force of the sub-gear is eliminated by the above opera-
tion.
(3) Align the timing mark (2 dot marks) of the camshaft
drive gear by turning the hexagon wrench head por-
tion of the exhaust camshaft with a wrench.
(4) Evenly loosen and remove the 22 bearing cap bolts
a little at a time for several times as in the sequence
shown.
(5) Remove the oil feed pipe, 9 bearing caps, and cam-
shafts.
HINT:
Arrange the bearing caps in correct order for installation.
22. DISASSEMBLE EXHAUST CAMSHAFTS

IFOLD ASSEMBLIES
(a) Uniformly loosen the 10 cylinder head bolts on one side
of each cylinder head in a little at a time for several times
as in the sequence shown, then do the other side as
shown. Remove the 20 cylinder head bolts and the plate

Do not drop the plate washer of the cylinder head bolt
into A area in the illustration. It will fall down to the oil
pan through the cylinder head and the cylinder block.
(b) Lift the cylinder head from the dowels on the cylinder
block, and place the 2 cylinder heads on wooden blocks.
HINT:
After lifting off the cylinder head, pry off the cylinder head and
the cylinder block with a screwdriver.
NOTICE:
Be careful not to damage the contact surfaces of the
cylinder head and the cylinder block.
The cylinder head should not be tilted so to secure the
valve lifter. If the cylinder head is tilted, remove the
valve lifter and check that the adjusting shim is set
correctly.
26. REMOVE RH EXHAUST MANIFOLD FROM CYLINDER
HEAD
(a) Remove the 4 bolts and the heat insulator.
(b) Remove the 8 nuts, the exhaust manifold and the gasket.

REPLACEMENT
1. REPLACE VALVE GUIDE BUSHINGS
(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 (09951-07100)
(c) Using a caliper gauge, measure the bushing bore diame-
ter of the cylinder head.
(d) Select a new guide bushing (STD or O/S 0.05).
If the bushing bore diameter of the cylinder head is greater than
10.306 mm (0.4057 in.), machine the bushing bore to the fol-
lowing dimension:
10.335 - 10.356 mm (0.4069 - 0.4077 in.)
If the bushing bore diameter of the cylinder head is greater than
10.356 mm (0.4077 in.), replace the cylinder head.
HINT:
The intake bushing and the exhaust bushing differ in their sizes.

(e) Gradually heat the cylinder head to 80 - 100°C (176 -
212°F).
(f) Using SST and a hammer, tap in a new guide bushing to
the specified protrusion height.
Protrusion height:
Intake
9.2 - 9.8 mm (0.362 - 0.386 in.)
Exhaust
8.2 - 8.8 mm (0.323 - 0.346 in.)
SST 09201-10000 (09201-01060),
09950-70010 (09951-07100)
(g) Using a sharp 5.5 mm reamer, ream the guide bushing
to obtain the standard specified clearance (See page
EM-45) between the guide bushing and the valve stem.
2. REPLACE SPARK PLUG TUBE GASKETS
(a) Bend the 4 ventilation case claws installed on the cylinder
head cover to an angle of 90° or more.
(b) Using a screwdriver, pry out the gasket.
NOTICE:
Be careful not to damage the cylinder head cover. Tape up
the screwdriver tip.
(c) Using SST and a hammer, tap in a new gasket until its sur-
face is flush with the upper edge of the cylinder head cov-
er.
