42.86 mm (1.6874 in.) for exhaust
If the cam lobe height is less than minimum, replace the cam-
shaft.
(c) Inspect the camshaft journals.
(1) Using a micrometer, measure the journal diameter.
Journal diameter:
26.959 to 26.975 mm (1.0614 to 1.0620 in.)
If the journal diameter is not as specified, check the oil clear-
ance.

(e) Using SST, align the holes of the camshaft main gear and
sub gear by turning the camshaft sub gear counterclock-
wise, then temporarily install a service bolt.
SST 09960-10010 (09962-01000, 09963-00500)
(f) Align the gear teeth of the main gear and sub gear, then
tighten the service bolt.
Torque: 5.4 NVm (55 kgfVcm, 48 in.Vlbf)
NOTICE:
Be careful not to damage the camshaft journals.

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.
