(10) Mark camshaft sprocket relative to timing
chain.
(11) Unbolt camshaft sprocket from exhaust cam-
shaft.
NOTE: Note the position of dowel pin for camshaft
sprocket alignment during reassembly.
(12) Remove camshaft sprocket.
CAUTION: Camshaft bearing caps must remain in
proper order and position.
(13) Mark and remove camshaft bearing caps.
(14) Remove the inlet and exhaust camshafts (Fig.
11).
INSTALLATION
CAUTION: The camshafts are sensitive to fractur-
ing. Ensure they are installed free of stress.
CAUTION: Pay attention to assignment of cam-
shafts. Camshaft code numbers are visible on the
thrust collar of the axial bearing.
CAUTION: Oil bucket tappets and camshaft bearing
points. Inspect ease of operation of bucket tappets.
(1) Install inlet and exhaust camshafts.
CAUTION: Install camshafts so that the two holes in
camshaft sprockets are positioned opposite and the
markings of the camshaft and camshaft bearing cap
are aligned.
(2) Align inlet and exhaust camshafts at axial
bearing (Refer to 9 - ENGINE/CYLINDER HEAD/
CAMSHAFT(S) - STANDARD PROCEDURE).
(3) Position piston of cylinder #1 to 30° TDC.
NOTE: Pay attention to markings on camshaft bear-
ing caps.
(4) Install camshaft bearing caps in the proper
order. Tighten bolts to 9N·m (80 lbs. in.).
CAUTION: Do not rotate engine counter clockwise.
(5) Position the piston of cylinder #1 to ignition
TDC.
NOTE: Pay attention to markings on camshaft bear-
ing caps.
(6) Install the bearing caps in reverse order at the
same point. Tighten bearing cap bolts evenly in steps
each of 1 turn.
NOTE: The piston of cylinder #1 must be positioned
at ignition TDC when the inlet camshaft is locked.
(7) Insert locking pin through the first camshaft
bearing cap into the whole in the camshaft sprocket.
NOTE: Do Not use old camshaft sprocket bolts.
(8) Fit camshaft sprocket with timing chain fitted
on, onto exhaust camshaft paying attention to posi-
tion of dowel pin. Tighten bolt to 18N·m (159 lbs.in.).
(9) Install timing chain tensioner (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT/CHAIN
AND SPROCKETS - INSTALLATION).
