Timing Component Alignment Marks: Locations
CAUTION: Incorrect removal or installation of the timing chain can result in damage to internal engine components.
NOTICE: For complete replacement and installation procedures for the timing chain, please refer to Timing Chain; Service and Repair. See:
Timing Chain/Service and Repair
INSTALL CHAIN
a) Set the position of the No. 1 cylinder to 20° ATDC.
NOTICE: To prevent the pistons from hitting against valves, these procedures must be performed in this order.
1) Set the crankshaft between 40 to 140° ATDC.
2) Set the cams of the intake and exhaust timing sprockets to 20° ATDC.
3) Reset the crankshaft to 20° ATDC.
b) Install the chain vibration damper with the 2 bolts.
Torque: 9.0 Nm (92 kgf-cm, 80 inch lbs.)
c) Align the timing marks of the camshaft timing sprocket, camshaft timing gear and crankshaft timing sprocket with each mark plate (colored in
yellow) of the timing chain.
HINT: To prevent the exhaust camshaft from springing back, turn it using a wrench and set it at the mark on the chain.
d) Install the chain tensioner slipper with the bolt.
Torque: 9.0 Nm (92 kgf-cm, 80 inch lbs.)
e) Install the chain tensioner with the 2 bolts.
1) While rotating the stopper plate of the chain tensioner upward as shown in the illustration, push in the plunger of the tensioner.
2) While rotating the stopper plate of the tensioner downward, insert a 2.5 mm (0.098 inch) diameter bar into the holes of the stopper plate
and the tensioner to hold the stopper plate.
3) Install the chain tensioner with the 2 bolts.
Torque: 9.0 Nm (92 kgf-cm, 80 inch lbs.)
4) Remove the bar from the chain tensioner.
f) Check the tension between the intake and exhaust camshaft timing sprockets.
