bearing No.1 has some holes.

3) Install intake camshaft (1) and exhaust camshaft (2).
Align knock pin (3) and match mark (4) with notches
(5) as shown in figure.
NOTE
Before installing camshafts, turn crankshaft
until key position faces upward.
Refer to “Timing Chain and Chain Tensioner
Removal and Installation”.

kgf-m, 8.0 lb-ft) by the specified procedure8) For engine with VVT, with hexagonal section (1) of
intake camshaft (2) held stationary with spanner or
the like, tighten bolt of intake cam timing sprocket
assembly (3) to specification.
Tightening torque
Intake cam timing sprocket bolt (a): 60 N·m (6.0
kgf-m, 43.5 lb-ft)
9) Install timing chain with crankshaft sprocket referring
to “Timing Chain and Chain Tensioner Removal and
Installation”.
10) Install timing chain cover referring to “Timing Chain
Cover Removal and Installation”.
11) Check valve lashes referring to “Valve Lash
(Clearance) Inspection”.
12) Perform Steps 10) to 14) of “Installation” of “Timing
Chain Cover Removal and Installation”.
