Installation
CAUTION!
After timing chain is removed, never turn
crankshaft and camshafts independently
more than such an extent (“a”, “b”) as shown
in figure.
If turned, interference may occur between
piston and valves and valves themselves,
and parts related to piston and valves may be
damaged.

1) Check that match marks (1) on intake and exhaust
camshaft timing sprockets are in match with notches
(2) on cylinder head as shown in figure.
2) Set key (3) and turn crankshaft to position key on
upside of crankshaft.3) Install timing chain to camshaft timing sprockets as
follows.
• For engine with VVT
Install timing chain by aligning dark blue plates (1)
of timing chain and triangle mark (2) on camshaft
timing sprockets.
• For engine without VVT
Install timing chain by aligning dark blue plates (1)
of timing chain and circle mark (5) on intake
camshaft timing sprocket and triangle mark (5) on
exhaust camshaft timing sprocket.
4) Fit crankshaft timing sprocket to timing chain by
aligning gold plate (3) of timing chain and circle mark
(4) on crankshaft timing sprocket. Then install
crankshaft timing sprocket fitted with chain to
crankshaft.
“a”: 90°4. Camshaft (IN and EX) allowable turning range.
By marks on camshaft timing sprocket within 15° from notches
on cylinder head on both right and left.
“b”: 15°5. Crankshaft allowable turning range.
By key on crankshaft, within 90° from top on both right and left.
