CAUTION:
 Never loosen the adjusting bolts (A), mounting bolts (black color) (B) of VVEL ladder assembly, or the
mounting bolts (C) of the VVEL control shaft position sensor. If loosened, the stroke of the cam lift will
be out of adjustment. In such a case, the replacement of the VVEL ladder assembly and the cylinder
head assembly is required.

Never loosen the mounting bolts (C) of the VVEL control shaft position sensor. VVEL control shaft
position sensor mounting bolts are required to be loosened for adjustment only when using a new
VVEL ladder assembly.
