6. Rotate the crankshaft to approximately 90° after

top-dead-center (ATDC).

DE240A

DE275A

7. Turn the camshaft drive pulley until the camshaft

and rocker arms are “unloaded” (all rocker arms in

“valve-closed” position).

8. Remove the three nuts securing the rocker arm

shaft; then using rubber bands or a large O-ring

secure the rocker arms together.
