(c) Remove the 12 bolts and 2 nuts.
(d) Insert the blade of SST between the crankcase,
chain cover and oil pan, then cut off the applied
sealer and remove the oil pan.
SST 09032-00100
NOTICE:
Be careful not to damage the contact surface of
the crankcase, chain cover and oil pan.
20. SET NO. 1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley until its groove and the
timing mark "0" of the timing chain cover are
aligned.
(b) Check that each timing mark of the camshaft timing
gear and sprocket is aligned with each timing mark
located on the No. 1 and No. 2 bearing caps as
shown in the illustration.
If not, turn the crankshaft by 1 revolution (360
) to
align the timing marks as above.
21. REMOVE CRANKSHAFT PULLEY
(a) Using SST, fix the pulley in place and loosen the
pulley bolt.

(a) Install the chain vibration damper with the 2 bolts.
Torque: 9.0 N*m (92 kgf*cm, 80 in.*lbf)
4. INSTALL CHAIN SUB-ASSEMBLY
(a) Set the No. 1 cylinder to TDC/compression.
(1) Turn the camshafts with a wrench (using the
hexagonal lobe) to align the timing marks of the
camshaft timing gear with each timing mark
located on the No. 1 and No. 2 bearing caps as
shown in the illustration.
(2) Using the crankshaft pulley bolt, turn the
crankshaft to position the key on the crankshaft
upward.
