Legacy GT LTD Sedan AWD F4-2.5L DOHC (1998)
-
When timing belts are not installed, four camshafts are held at the "zero-lift" position, where all cams on camshafts do not push intake and
exhaust valves down. (Under this condition, all valves remain un-lifted.)
-
When camshafts are rotated to install timing belts, #2 intake and #4 exhaust cam of left-hand camshafts are held to push their
corresponding valves down. (Under this condition, these valves are held lifted.) Right-side camshafts are held so that their cams do not
push valves down.
-
Left-hand camshafts must be rotated from the "zero-lift" position to the position where timing belt is to be installed at as small an angle as
possible, in order to prevent mutual interference of intake and exhaust valve heads.
WARNING DO NOT ALLOW CAMSHAFTS TO ROTATE IN THE DIRECTION SHOWN IN THE FIGURE AS THIS CAUSES
BOTH INTAKE AND EXHAUST VALVES TO LIFT SIMULTANEOUSLY, RESULTING IN INTERFERENCE WITH THEIR
HEADS.
