screwdriver [shank diameter 8 mm (.31 in.)] through the
hole (Engine with silent shafts).

one turn and realign timing marks. Then check to ensure
that the screwdriver can be inserted 60 mm (2.4 in.) or
more. Keep the screwdriver inserted until installation of

sprocket and camshaft sprocket in that order. There should
be no slack on the tension side.

excessive belt tension.
