(3) Make sure that the relationship between the tensioner
pulley center and the bolt center is as shown in the
illustration.
(4) Move the tensioner “B” in the direction of arrow while
lifting with a finger to give a sufficient tension to the tension
side of timing belt. In this condition, tighten bolt to secure
tensioner “B” . When the bolt is tightened, use care to
prevent shaft from turning together. If shaft is turned
together, belt will be overtensioned.

OIL PUMP SPROCKET INSTALLATION
(1) Block the counterbalance shaft in the same way as at the disassembly to prevent it from turning.
(2) Install the oil pump sprocket.
(3) Apply a proper amount of engine oil to the bearing surfaces
of the flange nuts.
(4) Tighten the flange nuts to the specified torque.

AUTO TENSIONER INSTALLATION
(1) If the auto tensioner rod is in its fully extended position, reset it as follows.
a. Clamp the auto-tensioner in the vise with soft jaws.
b. Push in the rod little by little with the vise until the
set hole A in the rod is aligned with the hole B in
the cylinder.
