INSTALLATION SERVICE POINTS
>>A<< CAMSHAFT SPROCKET BOLT 
INSTALLATION

AK201774

Tighten the camshaft sprocket bolt to 88 

± 10 N⋅m 

while preventing the camshaft from rotation using a 
wrench fitted on the hexagonal portion of the cam-
shaft.

sprocket 
bolt

V.V.T. sprocket

Camshaft

1. Apply a proper minimum quantity of engine oil to 

the following points.

• Camshaft end

• Insertion hole in V.V.T. sprocket (all over inside 

and outside surfaces)

• Threads and head of V.V.T. sprocket bolt

• Bearing surface of V.V.T. sprocket bolt

2. Install the V.V.T. sprocket onto the camshaft.
3. Make sure that the V.V.T. sprocket is installed all 

the way onto the camshaft. Holding the hexagonal 
portion of the camshaft with a wrench, check that 
the V.V.T. sprocket does not turn. 

AK201775

4. Holding the hexagonal portion of the camshaft 

with a wrench, tighten the V.V.T. sprocket bolt to a 
specified torque of 55 

± 5 N⋅m.

5. Holding the hexagonal portion of the camshaft 

with a wrench, check that the V.V.T. sprocket is 
not loose to turn.
NOTE: This check is to ascertain that the V.V.T. 
sprocket is locked at the most retarding position 
by means of internal pin.

>>D<< AUTO-TENSIONER INSTALLATION

AK201880AC

A

B

1. If the auto-tensioner rod remains in its fully 

extended position, reset it to the retracted position 
as follows:
(1) Clamp the auto-tensioner in a vise at right 

angles to the jaws.

CAUTION

Because the leak down of the auto-tensioner 
takes a long time, slowly insert the rod. If the rod 
is suddenly inserted, the auto-tensioner could be 
damaged.

(2) Push in the rod little by little with the vise until 

the set hole A in the rod is aligned with the set 
hole B in the cylinder.

AK300154

(3) Insert a piece of wire (1.4 mm diameter) into 

the set holes.

(4) Remove the auto-tensioner from the vise.

2. Install the auto-tensioner in position. Leave the 

wire installed until the auto-tensioner is 
completely installed.
