At this location the keyway in crankshaft drive gear will
be at the 12 o’clock position, visible when vibration
damper is removed. This is TDC of No. 1 cylinder’s
compression stroke. Also, with timing pin installed in
camshaft and crankshaft slots, this ensures that
camshaft-to-crankshaft timing is within specification.
