TIMING BELT
ENGINE OVERHAUL <4G63-Turbo>
11D-24
(2) Insert a crosspoint screwdriver with a shank
diameter of 8 mm through the plug hole. If it
can be inserted 60 mm or more, the sprocket
is in the correct phase. If the insertion depth is
up to 20 − 25 mm, the screwdriver is blocked
by the counterbalancer shaft. Then turn the oil
pump sprocket one turn and realign the timing
marks. Then check that the screwdriver can
be inserted 60 mm or more. Keep the
screwdriver inserted until installation of timing
belt is finished.
(3) Turn the oil pump sprocket counterclockwise
by one sprocket tooth.
5. Install the timing belt on the exhaust camshaft
sprocket, and hold it in place with a paper clip at
the point indicated in the drawing.
6. Turn the intake camshaft sprocket
counterclockwise to bring the timing mark on it
one sprocket tooth away from the mating timing
mark in the counterclockwise direction. Then
install the timing belt on the sprocket and hold it in
place with a paper clip.
NOTE: The timing marks will be aligned when the
belt is installed since the intake camshaft is turned
slightly clockwise by the force of the valve
springs.
7. Turn the exhaust camshaft sprocket clockwise to
align the timing marks, and make sure that the
intake camshaft sprocket timing marks are also
aligned.
8. Install the timing belt on the idler pulley, oil pump
sprocket, and crankshaft sprocket, in this order.
NOTE: There should be no slack in the installed
portion of the belt.
9. Install the timing belt on the tensioner pulley.
