Engine mechanism - Camshaft

Warning: if the air pressure in timing advance side oil duct is released earlier than that in
timing delay side oil duct, VVT driver assembly will move suddenly toward
delay side.This will cause the damage of lock pin.
(g) Remove VVT drive fixed bolts.
Notes:
It is strictly forbidden to remove other 4 bolts.
Under the condition of repeating using camshaft
timing sprocket, release lock pin at first, and then
install sprocket.


  1. Install VVT driver assembly.

  2. Install camshaft.
    Put VVT driver assembly together with intake camshaft.
    (a) As shown in the diagram, gently make VVT assembly
    hold camshaft and turn it toward left until straight pin is
    inserted into groove.
    Warning: it is strictly forbidden to turn camshaft
    timing sprocket toward timing delay side
    (toward right).


(b) Check there is no clearance between sprocket flange
and camshaft.
(c) Fix camshaft timing sprocket and then tighten flange
bolt.
Torque: 70 ±5N.m

(d) Check VVT driver assembly could move to timing
delay side and is locked at max. timing delay position.

(f) As shown in the diagram, align alignment mark with
timing mark on camshaft timing sprocket, and install
timing chain on the timing sprocket.
(g) Check forward mark and figure, and tighten bolts as
sequences shown in the diagram.
Torque: 13 ±0.78N.m


(h) Align alignment mark on the chain with timing mark on
