spring force of the sub gear has been eliminated by installation
of the service bolt.
(c) Using several steps, loosen and remove the 10 bearing
cap bolts uniformly in the sequence shown in the illustra-
tion. Remove the 5 bearing caps and No. 3 camshaft.
NOTICE:

bolts uniformly in the sequence shown in the illustration.
Torque: 16 NVm (163 kgfVcm, 12 ftVlbf)
30. INSTALL NO.3 CAMSHAFT SUB-ASSY
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while being installed. If the
camshaft is not kept level, the cylinder head or camshaft
may be damaged. To avoid this, the following steps must
be carried out.
(a) Apply new engine oil to the thrust portion and journal of
the camshaft.
(b) Align the timing marks (1 dot marks) of the camshaft drive
and driven gears.
(c) Place the camshaft to the cylinder head.
(d) Install the 5 bearing caps in their proper locations.
(e) Apply a light coat of engine oil to the threads of the bear-
ing cap bolts.
(f) Using several steps, install and tighten the 10 bearing cap
bolts uniformly in the sequence shown in the illustration.
Torque: 16 NVm (163 kgfVcm, 12 ftVlbf)
(g) Remove the service bolt.
