ii.

Align the timing mark on the camshaft timing gear assembly with the paint mark on the chain sub-assembly.

iii.

Align the timing mark on the camshaft timing exhaust gear assembly with the paint mark on the chain sub-assembly.

iv.

Using the hexagonal portion of the intake camshaft sub-assembly, install the camshaft timing gear assembly to the intake camshaft sub-assembly.

Check that the knock pin matches the pin hole from the No. 2 timing chain cover sub-assembly side.

vi.

Using a 10 mm bi-hexagon socket wrench, temporarily install the camshaft timing gear assembly with the bolt.

HINT:: Temporarily install the bolt enough that the camshaft timing gear assembly does not detach from the knock pin of the intake camshaft sub-assembly.

vii.

Using the hexagonal portion of the exhaust camshaft sub-assembly, install the camshaft timing exhaust gear assembly to the exhaust camshaft sub-assembly.

viii.

Temporarily install the 2 bolts.

HINT:: The 2 bolts can only be installed as shown in the illustration if the knock pin on the exhaust camshaft sub-assembly and the pin hole on the camshaft timing exhaust gear assembly match. If the 2 bolts cannot be installed, the knock pin and pin hole do not match.

Check the status of the camshaft timing gear assembly and camshaft timing exhaust gear assembly temporarily installed to each camshaft.

Camshaft timing gear assembly side:

Check that the chain sub-assembly does not overlap the No. 1 chain vibration damper as shown in the illustration.

NOTICE:: If the chain sub-assembly overlaps the No. 1 chain vibration damper, install it again.

Camshaft timing exhaust gear assembly side:

Check that the chain sub-assembly does not overlap the chain tensioner slipper as shown in the illustration.

NOTICE:: If the chain sub-assembly overlaps the chain tensioner slipper, install it again.

ii.

Using the hexagonal portion of the intake camshaft sub-assembly, hold the intake camshaft sub-assembly.

NOTICE:: ·

Do not damage the camshaft housing sub-assembly, cylinder head sub-assembly and spark plug tube.

·

Do not disassemble the camshaft timing gear assembly.

iii.

Using a 10 mm bi-hexagon socket wrench, tighten the bolt on the camshaft timing gear assembly.

Torque:: 86 N*m (877 kgf*cm, 63 ft.*lbf)

iv.

Using the hexagonal portion of the exhaust camshaft sub-assembly, hold the exhaust camshaft sub-assembly.

NOTICE:: Do not damage the camshaft housing sub-assembly, cylinder head sub-assembly and spark plug tube.

Using a 5 mm hexagon wrench, tighten the 2 bolts.

Torque:: 19 N*m (194 kgf*cm, 14 ft.*lbf)
