leys with the timing marks of the No.3 timing belt cover as
shown in the illustration.
If the marks do not align, remove the timing belt and reinstall it.
(c) Remove the crankshaft pulley bolt.
11. INSTALL RH ENGINE MOUNTING BRACKET

12. INSTALL NO.2 TIMING BELT COVER
(a) Check that the timing belt cover gasket has no cracks or
peeling, etc.
If the gasket has cracks or peeling, etc., replace it using these
steps:
Using a screwdriver and gasket scraper, remove all
the old gasket material.
Thoroughly clean all components to remove all the
loose material.
Remove the backing paper from a new gasket and
install the gasket evenly to the part of the timing belt
cover shaded black in the illustration.
After installing the gasket, press down on it so that
the adhesive firmly sticks to the timing belt cover.
(b) Install the timing belt cover with the 5 bolts.
Torque: 8.5 N´m (85 kgf´cm, 74 in.´lbf)
