1D-31 Engine Mechanical:
7) Install camshaft housing.
8) Tighten camshaft housing bolts as follows.
a) Apply engine oil to camshaft housing bolts.
b) Tighten camshaft housing bolts by hand.
c) Tighten camshaft housing bolts to 5 N⋅m (0.5 kgf-
m, 4.0 lb-ft) according to numerical order (“1”
through “21”) as shown in figure.
d) Retighten them by turning through 11 N⋅m (1.1
kgf-m, 8.0 lb-ft) in same manner as Step c).
Tightening torque
Camshaft housing bolt (a): 5 N⋅m (0.5 kgf-m,
4.0 lb-ft) and 11 N⋅m (1.1 kgf-m, 8.0 lb-ft) by
the specified procedure
9) 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)
10) Install timing chain with crankshaft sprocket referring
to “Timing Chain and Chain Tensioner Removal and
Installation”.
11) Install timing chain cover referring to “Timing Chain
Cover Removal and Installation”.
12) Check valve lashes referring to “Valve Lash
(Clearance) Inspection”.
13) Perform Steps 9) to 14) of “Installation” of “Timing
Chain Cover Removal and Installation”.

Intake Cam Timing Sprocket Assembly
Fit intake cam timing sprocket assembly to camshaft (2)
and hold hexagonal section of camshaft by using
spanner or the like.
Check if sprocket (1) is not turned by hand.
If moved, replace intake cam timing sprocket assembly.
Cam Wear
Using a micrometer, measure cam height “a”. If
measured height underruns its limit, replace camshaft.
