drive in the rear end of the intake camshaft.
NOTEInstall new camshafts using the following procedure.
(1) Remove the rocker arms.
(2) Lay the camshafts on the cylinder head and install
the bearing caps.
(3) Check that the camshaft can be easily turned by
hand.(4) After checking, remove the bearing caps and the

sensor, make sure that the crank angle sensor does
not turn.(3) Check that the ignition timing is set at the standard
value. (Refer to GROUP
8-Ignition System.)

9-98ENGINE <2.0L DOHC Engine> - Timing Belt22. REMOVAL OF TIMING BELT
Make a mark on the back of the timing belt indicating the
direction of rotation so it may be reassembled in the same
~direction if it is to be reused.
Caution
Water or oil on the belt shorten its life drastically, so
the removed timing belt, sprocket, and tensioner must
be free from oil and water. These parts should not be
washed. Replace parts if seriously contaminated.
If there is oil or water on each part check the front caseoil seals, camshaft oil seal and water pump for leaks.
26. REMOVAL OF CAMSHAFT SPROCKETS
(1) Using a wrench, hold the camshaft at its hexagon
(between the No.2 and No.3 journals) and remove the
camshaft sprocket bolt.
Caution
Locking the camshaft sprocket with a tool damagesthe sprocket.
(2) Remove the camshaft sprockets.
127. REMOVAL OF OIL PUMP SPROCKET
(1) Remove the plug on the side of the cylinder block.
(2) Insert a Phillips screwdriver [shank diameter 8 mm
(.31in.)] to block the left silent shaft.
(3) Remove the oil pump sprocket nut.
(4) Remove the oil pump sprocket.
33. REMOVAL OF TIMING BELT “B”
Make a mark on the back of the timing belt indicating the
direction of rotation so it may be reassembled in the same
direction if it is to be reused.
Caution
Water or oil on the belt shorten its life drastically, so
++the removed timing belt, sprocket, and tensioner must
be free from oil and water. These parts should not be
washed. Replace parts if seriously contaminated.
If there is oil or water on each part check the front caseoil seals, camshaft oil seal and water pump for leaks.

INSPECTIONWSKCACTIMING BELTS
The timing belts must be checked closely. Should the followingdefects be evident, replace the belt with a new one.
(1) Hardened back surface rubber
Glossy, non-elastic, and so hard that no mark is produced
even when scratched by a
fingernai.1.(2) Cracked back surface rubber.
(3) Cracked or separated canvas.
(4) Cracked tooth bottom.
(5) Cracked side.J(6) Abnormal wear on side.
NOTE
Normal belt should have clear-cut sides as if cut by a sharp
knife.(7) Abnormal wear on teeth.
Initial stage:
Canvas on load side tooth flank worn (Fluffy canvas
fibers, rubber gone and color changed to white, and
unclear canvas texture)
Final stage:Canvas on load side tooth flank worn down and rubber
exposed (tooth width reduced)
(8) Missing tooth.
TENSIONER PULLEY AND IDLER PULLEY
(1) Turn the pulleys to check for possible binding, excessive
play, and unusual noise. Replace the pulley if any of these
defects is evident.
(2) Replace if there is a grease leak.

(1) Check the auto tensioner for possible leaks and replace as*
necessary.(2) Check the rod end for wear or damage and replace as
necessary.(3) Measure the rod protrusion. If it is out of specification,
replace the auto tensioner.
Standard value: 12 mm

(4)Using a vise with soft jaws push in the auto tensioner rod. Ifthe rod can be easily retracted, replace the auto tensioner.
You should feel a fair amount of resistance when pushing
the rod in.
,J-Caution
’1. Clamp the auto tensioner in the vise so it maintains
a level position.
2. If the plug at the bottom of the auto tensioner
protrudes, surround it with a plain washer as
illustrated to prevent the plug from being in direct
contact with the vise.
