REMOVAL SERVICE POINTS
 
 
<<A>> TIMING CHAIN TENSIONER REMOVAL
1. Insert a flatblade screwdriver into the release hole of the timing chain tensioner to release the latch.
cautionThere is danger that the chain tensioner plunger could be thrown away from the body, fully push it [10 mm (0.393 in)or more] to the bottom with a stiff wire etc. and secure it there.
2. Push the tensioner lever by hand and push in the plunger of the timing chain tensioner until it hits the bottom. Then, insert a hard wire (piano wire or the like) of Φ1.5 (0.095 in) or hexagonal bar wrench [1.5 mm (0.059 in)] into the fixing hole of the plunger.
3. Remove the timing chain tensioner.
 

 
 
<<B>> EXHAUST CAMSHAFT SPROCKET BOLT REMOVAL
1. Hold the hexagonal portion of the exhaust camshaft with a wrench and loosen the exhaust camshaft sprocket bolt.
 

 
 
<<C>> INLET V.V.T. SPROCKET BOLT REMOVAL
1. Hold the hexagonal portion of the inlet camshaft with a wrench and loosen the inlet V.V.T. sprocket bolt.
 
 
 
 
INSTALLATION SERVICE POINTS
 
 
>>A<< INLET V.V.T. SPROCKET ASSEMBLY/INLET V.V.T. SPROCKET BOLT INSTALLATION
1. Assemble the inlet V.V.T. sprocket assembly in the following procedure.
(1) Make sure that the knock pin of the inlet camshaft assembly is positioned facing straight upward.
(2) Apply an appropriate and minimum amount of engine oil to the circumference of the tip of the inlet V.V.T. sprocket assembly and the entire circumference of the area into which the inlet V.V.T. sprocket assembly is inserted.
(3) Slowly insert the inlet V.V.T. sprocket assembly into the normal position of the inlet camshaft assembly with its knock pin hole facing straight upward.
2. Install the V.V.T. sprocket.
3. Make sure that the V.V.T. sprocket is securely inserted into the bottom and that the V.V.T. sprocket does not rotate with the hexagonal portion of the camshaft secured with a wrench.
4. Hold the hexagonal portion of the camshaft with a wrench and tighten the inlet V.V.T. sprocket bolt to the specified torque.
Tightening torque: 59 ± 5 N·m (44 ± 3 ft-lb)
 
 
 
>>B<< EXHAUST CAMSHAFT SPROCKET/EXHAUST CAMSHAFT SPROCKET BOLT INSTALLATION
1. Assemble the exhaust camshaft sprocket assembly in the following procedure.
(1) Make sure that the knock pin of the exhaust camshaft assembly is positioned facing straight upward.
(2) Slowly insert the exhaust camshaft sprocket into the normal position of the exhaust camshaft assembly with its knock pin hole facing straight upward.
2. Install the exhaust camshaft sprocket.
3. Make sure that the exhaust camshaft sprocket is securely inserted into the bottom and that the exhaust camshaft sprocket does not rotate with the hexagonal portion of the camshaft secured with a wrench.
4. Hold the hexagonal portion of the camshaft with a wrench and tighten the camshaft sprocket bolt to the specified torque.
Tightening torque: 59 ± 5 N·m (44 ± 3 ft-lb)
 
 
 
>>C<< TIMING CHAIN/TIMING CHAIN GUIDE/TENSIONER LEVER INSTALLATION
1. Align the timing mark of the inlet V.V.T. sprocket and the exhaust camshaft sprocket.
2. Align the crankshaft sprocket keys with illustrated positions.
3. Align the link plate with the timing mark of the exhaust camshaft sprocket and loop the timing chain.
4. Align the link plate with the timing mark of the inlet V.V.T. sprocket to loop the timing chain.
Rotate the inlet V.V.T. sprocket by one or two teeth to align with the timing mark.
5. Align the timing mark of the crankshaft sprocket with the link plate to loop the timing chain. Because the timing chain slacks, hold it to prevent the timing mark from coming off the link plate.
6. Make sure that the timing mark of each sprocket is aligned with the link plate of the timing chain at all of three locations.
7. Install the timing chain guide and tensioner lever.
 
 
 
>>D<< TIMING CHAIN TENSIONER INSTALLATION
cautionTo prevent the plunger on the timing chain tensioner from popping out, after mounting the tensioner lever and chain guide, mount the timing chain tensioner securely to its prescribed location.
1. Install the timing chain tensioner on the cylinder block and tighten it to the specified torque.
Tightening torque: 10 ± 2 N·m (89 ± 17 in-lb)
2. Remove the hard wire (piano wire or the like) of Φ1.5 (Φ0.059 in) or hexagonal bar wrench [1.5 mm (0.059 in)] from the timing chain tensioner. This enables the plunger of the timing chain tensioner to push the tensioner lever to keep the timing chain tight.
