TIMING BELT INSTALLATION
(1) Place the exhaust side camshaft sprocket in a position
where its timing mark is one tooth offset from the timing
mark on the rocker cover in the counterclockwise direction.
NOTE
Even if the timing marks on the sprocket and the rocker
cover are brought into alignment, the exhaust camshaft
is forced back by the valve spring tension. It is stabilized
at a position one tooth before the timing mark.
(2) Align the timing mark on the intake side camshaft sprocket
with that on the rocker cover.
NOTE
Even if the timing marks on the sprocket and the cover
are brought into alignment, the intake camshaft is forced
to turn one tooth in the clockwise direction by the valve
spring tension and stabilized there.
(3) Place the timing mark on the crankshaft sprocket one
tooth this side from the mated timing mark as in the case
of the camshaft sprocket.
(4) Align the timing mark on oil pump sprocket with its mating
mark.
(5) Remove the plug on cylinder block and insert a Phillips
screwdriver (shank diameter 8 mm) through the hole
(Engine with counterbalance shafts).
If it can be inserted as deep as 60 mm or more, the
timing marks are correctly aligned. If the inserted depth
is only 20 – 25 mm, turn the oil pump sprocket one turn
and realign timing marks. Then check to ensure that the
screwdriver can be inserted 60 mm or more. Keep the
screwdriver inserted until installation of timing belt is
finished.
